Answer:
The principle difference between aerobic and anaerobic process is aerobic process requires oxygen and generate more energy whereas anaerobic process occurs in absence of oxygen and generate less energy.
Explanation:
Aerobic process or aerobic respiration include glycolysis,TCA cycle and oxidative phosphorylation.As a result during Aerobic respiration a glucose molecule undergo complete oxidation to form CO2 and H2O along with 38 molecules of ATP.
On the other hand Anaerobic process or Aerobic respiration only involves glycolysis.As a result no TCA cycle and oxidative phosphorylation occur during Anaerobic process.Glycolysis that occur during Anaerobic produces only two molecules of ATP.
During anaerobic respiration the end product of pyruvate undergo lactic acid fermentation to form as well as to regenerate NAD+.
The process that requires oxygen is called an aerobic process while a process that doesn’t air is called anaerobic process.
Explanation:
Processes in nature are aerobic and anaerobic. For anaerobic processes , air is not an essential element while it is not so for aerobic processes. There are several examples of aerobic and anaerobic processes in nature. Respiration, an important biological process sometimes takes place anaerobically in some organisms while most of the organisms respire aerobically.
Some bacteria can respire anaerobically. When organisms like yeast respire anaerobically alcohol and carbon dioxide is released.

Answer:
to learn if an individual has a chance of developing genetic conditions later in life
to learn if an individual has a genetic condition
to learn if an individual has a chance of passing on a genetic condition
Explanation:
Genetic screening looks a selection of genes from an individual to identify variation or mutations that are associated with disease. This can be used to:
learn if an individual has a chance of developing a genetic condition later in life. Examples of such diseases include Huntington's disease, or genetically-linked cancers such as BRCA-linked ovarian and breast cancers. Clinicians could identify patterns in a family and suggest that an individual might want to get tested for a disease-causing mutation, even if they don't yet have any symptomsto learn if an individual has a genetic condition - genetic screening might be suggested if an individual has a collection of symptoms that are not explained, or might be associated with a particular disease. Genetic diseases often appear in childhood, so those undergoing this type of testing could be quite young.to learn if an individual has a chance of passing on a genetic condition if an individual with a genetic disease or a genetic disease prevalent in their family wants to have children, they might wish to undergo testing to see if they could pass on the condition. Genetic screening might even be used to select for embryos that don't carry the disease-causing mutation after fertilisation.genetic screening cannot tell if an individual has infections inside his or her body. Infections are a type of disease that are not caused by our DNA, and the testing will not be able to provide any information about infections or any other non-genetic health problemsNew evidence does not change what scientists already believe to be true.

Choose a specific site for further study where eutrophication is a problem (such as Chesapeake Bay, the Baltic Sea, or the Gulf of Mexico). List some sources of nitrogen and/or phosphorous to the water body and describe some of the ecological problems due to eutrophication at this specific site.
Explanation:
Due to the commercial farming activities in the MidWest, fertilizers and pesticides are usually washed away by precipitation and drain into the Gulf of Mexico. These elements (mainly nitrogen and phosphorus) offer much nutrients for algae causing them to thrive into algae blooms. Bacteria then find ‘fodder’ in dead algae breaking them down for energy sources. The bacteria, mostly aerobic, take up most of the oxygen from the water as they thrive. This makes the waters of the Gulf hypoxic hence the other marine organisms such as fishes cannot thrive. Actually, the ecosystem dies and the region is recognized as a' dead zone'.

In regards to the Amoeba Sisters' video about blood type, if a man with Type A blood and a woman with Type O blood have a child that needs a blood transfusion, what blood type would not be able to donate to the baby?
Answer:
Explanation:
Donors with blood type A can donate to recipients with blood types A and AB. Donors with blood type O. can donate to recipients with blood types A, B, AB and O (O is the universal donor to all blood
A child born to a man with Type A blood and a woman with Type O blood cannot receive blood from Type B or Type AB donors.
When determining which blood types can donate to a baby born to a man with Type A blood and a woman with Type O blood, we need to understand the compatibility rules of blood transfusion.
When a man with Type A blood and a woman with Type O blood have a child, the child can have either Type A (AO genotype) or Type O (OO genotype) blood. In the ABO blood group system, individuals with Type A blood can receive blood from Type A and Type O donors, while individuals with Type O blood can only receive blood from Type O donors.
If the child needs a blood transfusion, they would not be able to receive blood from Type B or Type AB donors. This is because Type B blood contains B antigens that would trigger an immune response in the child with Type A or Type O blood. Similarly, Type AB blood contains both A and B antigens, making it incompatible with the child's Type A or Type O blood.
Therefore, when considering blood donation for the child of a man with Type A blood and a woman with Type O blood, it is important to ensure compatibility based on the ABO blood group system to prevent adverse immune reactions during the transfusion.
The presence of lactic acid in the cell of an animals muscle tissue is an indication that the
Answer:
The animal has been performing vigorous activity with an insufficient oxygen availability in its muscles.
Explanation:
Lactic acid is an alpha-hydroxy acid (AHA) that is fundamental in the biochemical processes of the body.
During normal levels of oxygen in the body, the carbohydrates that are present in the body are transformed into water and CO2. On the other hand, when oxygen levels are low, lactic acid is produced.
Therefore, when an animal is performing vigorous exercise and the levels of oxygen in the body are low or insufficient, the muscles begin to respire anaerobically and, instead of CO2 and H2O, lactic acid is produced.
So, the presence of lactic acid in the cell of an animals muscle tissue is an indication that the animal has been performing vigorous activity with an insufficient oxygen availability in its muscles.

What benefits do plants with a smooth stem have? Does the stem type protect a plant?
Smooth stem plants like guava, eucalyptus etc do have a smooth layer of bark over its stem that comes out as a skin when they shed their barks. Whereas most of the other plants like mango, banyan etc do have a rough corrugated layer of bark over their stem.
The smooth stem doesn’t let water to accumulate in the bark which can led to infections to the tree. It also doesn’t allow any seed to settle on bark that can led to growth of parasites. Thereby this smooth bark saves the trees from some of the probable harm to the tree.
Final answer:
Plants with smooth stems benefit from less resistance to water flow and reduced pest habitation. Modified stems like rhizomes, stolons, runners, corms, tubers, and bulbs aid in survival and reproduction, storing food and facilitating spread. Stem type contributes to a plant's adaptability and protection.
Explanation:
Benefits of Plants with Smooth Stems
Plants with smooth stems often have advantages in environments where there is fast-flowing water or frequent rainfall. A smooth surface can reduce resistance and allows water to flow off easily, thereby reducing damage from strong currents or heavy rain. Furthermore, a smooth stem can be less habitable for pests and parasites, which often find it difficult to grip onto the slick surface. From an evolutionary perspective, plants have developed different types of stems, including modified stems, to adapt to their environments and enhance their survival and reproduction.
Modified Stems
Rhizomes, stolons, and runners provide an advantage by allowing the plant to spread horizontally and produce new offspring at a distance from the parent, good for colonization. On the other hand, corms, tubers, and bulbs store food, which can be crucial for survival during periods of dormancy or when conditions are not conducive to growth. These modified structures often contain nodes and axillary buds, indicating that they are indeed modified stems rather than roots.
In summary, the type of stem can indeed protect a plant by aiding in its adaptation and survivability. Whether it's through physical characteristics like a smooth surface or modifications for storage and reproduction, the stem is a vital component of a plant's success.
How is Newtons second law applied to football?
Answer:
More force from a football player's throw can accelerate a football faster.
Explanation:
Force = mass * acceleration
Final answer:
Newton's second law, stating that the change of motion is proportional to the force applied, is central to football actions like kicking, throwing, and pushing between players. The law explains how the force applied influences the ball's or player's acceleration, demonstrating the physical principles at play during a football game.
Explanation:
Newton's second law states that the change of motion of a body is proportional to and in the direction of the force acting on it. This principle is vividly demonstrated in football through various actions such as kicking, throwing, and pushing between players.
When a football is kicked or thrown, the force applied to the ball by the foot or hand causes it to accelerate in the direction of the force. The amount of force and the mass of the football determine its acceleration, according to the formula F=ma (force equals mass times acceleration). This is why quarterbacks and kickers need to apply significant force to throw or kick the ball long distances.
In the scenario of a lineman pushing against an opponent, each player exerts a force on the other. According to Newton's third law, these forces are equal and opposite. However, the player who can apply a greater force to the ground through their feet (thanks to friction and lower body strength) will be able to exert a higher force against the opponent, potentially overcoming them. This demonstrates that despite the equal and opposite forces, the outcome depends on the relative strengths and techniques of the players.
Which best describes the advantage of pest resistance?
Answer:
c) Farmers do not have to use harsh chemicals to save their crops.
Explanation:
Options:
a) Pests are mutated and tolerate more.
b) Pesticides become less effective.
c) Farmers do not have to use harsh chemicals to save their crops.
d) Farmers can kills weeds without killing their cash crop.
Pest resistance refers to a situation in which pests, e.g. weeds, insects, etc., become resistant by pesticides. This means that these chemicals are no longer effective on these organisms.
Although this could be seen as a negative effect, it could actually have advantages. Experts in biological control strategies aim to minimize the use of toxic pesticides and change to sustainable systems of pest management. Therefore, if a pest becomes resistant, farmers do not have to use harsh or toxic chemicals to save their crops and may opt, instead, for biological control methods, such as the use of nematodes to control pests.
If you were to hike the distance from Point A to Point B, what would be the gradient of your climb?
Final answer:
The gradient of a hike represents the steepness of the climb. The specific gradient of a hike from Point A to Point B depends on the change in elevation and horizontal distance between the two points. In the given example, the gradient is calculated to be 13%.
Explanation:
The gradient of a hike represents the steepness of the climb. It is a ratio of the change in elevation to the horizontal distance traveled. In this case, if you were to hike from Point A to Point B, the gradient of your climb would depend on the specific locations of Point A and Point B, as well as the change in elevation between them.
For example, if Point A is located at 3440' and Point B is located at 3720' with a rise of 280', and the run is about 2200', then the average slope or gradient would be calculated as (280)(100)/2200= 13%.
Therefore, the gradient of your climb would be 13% if you hiked from Point A to Point B.
The speed of sound is the measure of how far it travels in a certain amount of time. The speed of sound will differ depending on which of the following?
A) The frequency of sound.
B) Where the sound originated from.
C) The pitch of sound.
D) The material the sound is traveling through.
Explanation:
The speed of sound depends on the elasticity and density of the medium through which it is traveling. In general, sound travels faster in liquids than in gases and faster in solids than in liquids. The greater the elasticity and the lower the density, the faster sound travels in a medium.
Answer:
Option D is the correct answer.
Explanation:
The speed of sound refers to the distance travelled per unit time by a sound wave as it moves. At 68º F its speed in air is about 343 meters per second, or 767 miles per hour or a kilometer in 2.9 seconds. There are two big factors to be considered: first one is temperature and the material the sound is traveling through, so the last option is the right answer.

Humidity tends to be
Answer:
the humidity causes moisture
Explanation:
Final answer:
Relative Humidity tends to be higher when the air temperature is closer to the Wet Bulb Temperature, because this indicates the air is nearly saturated with water vapor, approaching 100% relative humidity.
Explanation:
When the air temperature is closer to the Wet Bulb Temperature, the Relative Humidity tends to be higher. Relative humidity is the ratio of water vapor in the air to the amount of water the air can hold at a given temperature and pressure, expressed as a percent. Warm air can hold more water vapor than cold air; therefore, if the amount of water in the air stays the same and the temperature increases, the relative humidity decreases. However, when air temperature and wet bulb temperature are similar, it indicates that the air is nearly saturated with water vapor, and the relative humidity is approaching 100%, making the air very moist and potentially leading to fog or precipitation if conditions are right.

How do the random distribution of chromosomes and crossovers create more variation in the resulting gametes?
When cells divide during meiosis, homologous chromosomes are randomly distributed during anaphase I, separating and segregating independently of each other. This is called independent assortment. It results in gametes that have unique combinations of chromosomes.
Crossing over creates new combinations of genes in the gametes that are not found in either parent, contributing to genetic diversity.
Sexual reproduction results in genetic variation through crossing-over, independent assortment, and random fertilization, leading to a vast number of unique genetic combinations.
Explanation:The process of sexual reproduction is able to produce a significant amount of genetic variation in offspring. This variation emanates from three pivotal events: crossing-over, independent assortment, and random fertilization. Crossing-over is a critical event during meiosis where there is a reciprocal exchange of DNA between maternal and paternal chromosomes. This leads to chromosomes with a mix of genetic material from both parents, which are then passed into gametes.
Moreover, the independent assortment of chromosomes during metaphase I further contributes to genetic diversity. This occurs when homologous chromosomes align randomly at the metaphase plate, and each daughter cell receives a random mix of maternal and paternal chromosomes. Given that humans have 23 pairs of chromosomes, over eight million combinations can result just from this random assortment. This figure doesn't even include the additional diversity brought about by crossing-over.
Lastly, random fertilization amplifies the potential for variation, as the combination of one randomly selected gamete with another during fertilization results in a zygote with a unique genetic makeup. These mechanisms ensure that the likelihood of producing two genetically identical gametes is extremely unlikely, which plays an important role in the survival and evolution of species.

Explanation:
As a rule, molecules can either pass within the cell without applying energy throughout the process of passive transport (Molecules of oxygen for example). The molecules that are big and un-polar are unable to pass through the cell membrane easily. These molecules will need the energy to have the ability to go through the cell membrane. These molecules possibly might go through with the assistance of the carrier or facilitated proteins (Molecules of glucose for example).
Gastric lipase has an optimal temperature of 37°C. Sketch an optimal temperature graph below.
Answer:
See attached picture
Explanation:
An optimal temperature graph plots the rate of the enzyme reaction against the temperature. We know that the optimal temperature of this enzyme is 37C, so we know that at this temperature, the rate will be highest.
Additionally, there will be a minimum temperature required for the enzyme to work at all, which is why the line graph slowly increases the rate until its optimum at 37C.
Finally, at higher temperatures, the enzyme will become denatured and its activity will be diminished. This is why the activity drops at high temperatures and is non-existent at very high temperatures.
