Answer:

The stream becomes polluted

Explanation:

In this case, the insecticides are being used as a measure of pest control i.e. to kill the moths and save the Douglas Fir trees. Intended purpose of spraying insecticides:

If the moths are eliminated, the Douglas Fir trees will prosper. Their needles will be intact and it would be more suitable for the birds to use the trees for nesting. With their competition eliminated, more birds will choose the trees for nesting which would result in an increase in their population.

Unintended Consequence:

Insecticides are chemical agents that kill insects or pests. These chemical compounds are toxic and a health hazard humans and animals. As the insecticides are sprayed on the trees, some quantity of them will reach the stream and pollute the water.

Answer:

The answer is C. Pepsin becomes inactive as soon as it reaches small intestine.

Explanation:

Enzymes are pH specific. They once work at those specific values and if those are changed they either degrade or become inactive. The pH of stomach is acidic and that of the small intestine is basic. Therefore the enzymes will become inactive when it enters small intestine.

Answer:

C, It becomes inactive

Explanation:

Enzymes have an ideal pH, at which they best function. Many enzymes cannot function

at all outside their ideal pH range. Pepsin functions best in the extreme acid

environment of the stomach and will, therefore cease to function in the much higher pH

of the small intestine.

Lightning was common on early Earth is the discovery which would  weaken the primordial soup hypothesis of the origin of life.

Explanation:

The hypothetical conditions on which the theory regarding the origin of life is dependent is the Primordial Soup theory. Proposed by Alexander Oparin, this theory states that objects like hydrogen, water vapor, carbon etc. Forms the living beings on Earth. This theory though doesn't talk about the impact of uncommon asteroids in life formation on Earth.

Answer:

As depth increases in the benthic zone, there is a high pressure and limited light.

Explanation:

Benthic zone begins at the shoreline and extends downwards with the continental shelf. The benthic zone covers 70% of all earth. It can host ecosystems such as a coral reef and kelp forest. In some parts of the benthic zone, at a deeper water zone, there is high pressure, low temperature and low sunlight.

Pressure: As depth increases in the benthic zone, pressure also increases. High pressure in the zone makes a homogeneous environment and lack of oxygen develop anaerobic zone formation.

Light: In deep waters (between 200 and 1000 m), light is unable to penetrate to the lower level. Insufficient light leads toward a low photosynthesis rate which is the reason that food source comes from dead and decaying organisms drifting down from upper layers. This condition also leads to the formation of anaerobic conditions.

Two factors that limit life in the benthic zone as depth increases are the availability of light for photosynthesis and the increase in pressure.

Two limiting factors associated with increased depth in the benthic zone include light availability and pressure. First, light availability decreases as depth increases, affecting the ability of organisms to carry out photosynthesis. This results in fewer plant species and a distinct shift in the types of organisms found in these deeper areas.

Secondly, the pressure increases significantly in the benthic zone as depth increases, which can affect the physiology of many organisms. It makes the survival hard for them.

Answer: True.

Explanation:

All the organism cells read the same genetic blueprint. So they all have the exact same DNA.

True. All of an organism's cells have the exact same DNA.

The DNA in an organism is present within the nucleus of every cell and contains the genetic information necessary for the development, functioning, and reproduction of that organism. During the process of cell division, the DNA is replicated, and each daughter cell receives an identical copy of the parent cell's DNA.

This means that all cells in an organism, whether they are skin cells, muscle cells, or nerve cells, contain the same genetic information encoded in the DNA. However, not all genes in the DNA are actively expressed in every cell. Different cells express specific sets of genes that are relevant to their particular functions and characteristics. This process of gene regulation allows cells to differentiate and specialize into various cell types while still sharing the same DNA.

Exceptions to this general rule occur in certain cases such as somatic mutations, which can introduce changes in specific cells' DNA during an organism's lifetime. Additionally, some organisms, such as certain types of plants, may exhibit genomic mosaicism, where different cells contain distinct variations of the DNA due to somatic mutations or epigenetic modifications. However, on a fundamental level, the DNA sequence within an organism's cells is the same.

Answer:

The answer is 2 milliliters or 2 mL.

Explanation:

Betamethasone is considered a steroid medication. It is used to treat varieties of condition such as skin rashes, arthritis and in the case above, fetal lung maturity. When it comes to fetal lung maturity, Betamethasone is usually administered to women who are in the gestation period of 34 weeks to 36 weeks, depending on the condition. It is administered through the muscles also known as "IM" or "intramuscular" and the usual dosage is 12 mg. In the case above, it is asking for the mililiters of administration considering that the order was 12 mg IM daily for three days. Since the Betamethasone comes in a 6mg/mL vial, you have to compute how much Betamethasone is to be given.

If there's 6 mg of Betamethasone per 1 mL, then this means that there's 12 mg of the medication in 2 mL.

So, the answer is 2 mL.

Answer:

If I were studying the causes of cancer, the topic which might interest me is "The topic of spindle-fibre structure.".

Explanation:

In cell division, the accurate segregation of chromosomes is coordinated with the complex structure of spindle fibre in cell. The mitiotic structure is consisted of two apparatus, one is centrosomes and the other is microtubules. Mitiotic spindle is formed during the polymerization process of the microtubules in centrosome. Any kind of disruption in the structure of the microtubules causes aberration in the spindle fibre structure and error in the number of chromosomes. This change is one of the major causes of developing cancer.

Answer:

Explanation: Active transport uses energy (ATP) for the moving the molecules in and out of the cellular membranes and therefore remain active, while in passive transport the molecules do not use energy for their movements and so the name is given as passive.

Active transport requires the expenditure of energy in the form of ATP to move substances against a concentration gradient, while passive transport does not require any energy and permits substances to move naturally from an area of higher concentration to one of lower concentration.

The fundamental difference between active transport and passive transport involves the need for energy. Active transport requires energy in the form of ATP to move molecules against a concentration gradient - often through a membrane protein structure that functions as a pump. A known example is the sodium-potassium pump that uses energy to transport sodium out of and potassium into cells, both against their concentration gradient.

On the other hand, passive transport, does not require energy. Substances move from an area of higher concentration to lower concentration without the use of ATP or any form of energy. Passive diffusion and facilitated diffusion are two examples of passive transport.

In active transport, substances usually move from an area of low concentration to an area of high concentration, which is often termed as moving 'uphill'. The cell needs to expend energy in the form of ATP for this process. Passive transport happens naturally and does not require energy, as substances move from an area of high concentration to an area of lower concentration, going 'downhill'.

The important reason for the bed linens remaining wrinkle free is to help keep the skin healthy and also to prevent pressure injuries.

Explanation:

The linens must be changed after personal care like bed bath, or at the time of bedding or when the sheet gets damped soiled, or when it is required for straightening. For more hygienic practice the sheet should be changed in every two weeks or may say in 15 days. In case of excessive sweating, like night sweat, or general sweating it should be changed once in a week. In this way various diseases and infections can be avoided. In most cases of skin diseases the primary reason is the bedding type. When sheets used for long time a lot of microbes starts growing that are often invisible to naked eyes.

Answer:

Each base pair is formed from two complementary nucleotides (purine with pyrimidine) bound together by hydrogen bonds. The base pairs in DNA are adenine with thymine and cytosine with guanine.

Explanation:

In DNA, four types of nucleotide bases are present which forms base pair with each other such as adenine pairs with thymine and cytosine pairs with guanine. Thus, the correct option is A.

A nucleotide is composed of a nitrogenous base, a deoxyribose sugar, and a phosphate group. Nitrogenous bases are of two different types on the basis of nature of the ring present in the base: Purine and Pyrimidines.

Purines are made up of a pyrimidine and an imidazole ring. Purines include adenine and guanine. Pyrimidines are similar to pyridine in structure. These are of three types: Thymine, cytosine and uracil. In DNA, adenine and guanine are present along with thymine and cytosine.

Adenine base pairs with the thymine and forms two hydrogen bonds whereas cytosine base pairs with the guanine base with the help of three hydrogen bonds.

Therefore, the correct option is A.

240.5 gram DNA is in an adult human’s body.

Explanation:

DNA is the genetic material in human body. It is given that each human cell has approximately 6.5 picograms of DNA. It is also given that there are 37 trillion cells in the body.

We have to calculate the amount of DNA in human body.

Number of cells=37 trillion = [tex]3.7 \times 10^1^3[/tex]    

Amount of DNA per cell= 6.5 picogram = [tex]6.5 \times 10^-^1^2g[/tex]

Total amount of DNA in body= [tex]3.7 \times 10^1^3 \times 6.5 \times 10^-^1^2[/tex]

=240.5 g

Final answer:

To find the total amount of DNA in an adult human body, multiply 37 trillion cells by 6.5 picograms per cell and convert to grams. The result is approximately 240.5 grams of DNA.

Explanation:

To calculate the total amount of DNA in an adult human body, we will multiply the number of cells by the amount of DNA per cell. According to the question, an adult has approximately 37 trillion cells, and each cell has roughly 6.5 picograms of DNA. To find the total DNA in grams, we proceed as follows:

Total DNA (in grams) = number of cells ×amount of DNA per cell

Total DNA (in grams) = 37 trillion cells × 6.5 picograms/cell

We then convert the number of cells to a numerical value and picograms to grams:

Total DNA (in grams) = (3.7 × 10¹³  cells) × (6.5 ×10⁻¹² grams/cell)

Now, we multiply these two values:

Total DNA (in grams) = 3.7× 6.5 ×10¹³ × 10⁻¹²

Total DNA (in grams) = 24.05  10¹

Total DNA (in grams) = 240.5 grams

Therefore, the correct answer is that an adult human body contains approximately 240.5 grams of DNA.

Yes, the abiotic components interact with the biotic components in an ecosystem.

Explanation:

The abiotic components are the non- living components of an ecosystem. The biotic components are the living components of an ecosystem. Abiotic factors such as sunlight, temperature etc directly affect the biotic components.

For example, the light of the sun is an abiotic component which provides energy to the biotic components, plants, to produce food. Soil is also an abiotic component which provides nutrients and water for the plants which are biotic components.

Abiotic and biotic factors interact in an ecosystem.

Explanation:

An ecosystem has several biotic and abiotic factors. Abiotic factors include water, sunlight, rocks , minerals etc. biotic factors include all the life forms of  the ecosystem. Abiotic factors aid the growth and development of biotic factors in an ecosystem.

The amount of sunlight, water and minerals available can directly influence the plant and animal life of an area. Biotic component scan also contribute to altering the abiotic factors like water availability.

Ways to recover grassland ecosystem after volcanic revolution:  

The volcanic eruption destroys a grassland ecosystem. They burns the place and the plants. The dusts cover up the leaves and the heat kills the seeds and spores of the plants. The recovery isn’t easy and fast.  

Thus the grassland ecosystem again revives from the devastating hands of the volcano.  

Final answer:

The grassland ecosystem can recover from a volcanic eruption through primary succession starting with lichen growth, followed by the establishment of pioneer species such as annual plants and grasses, and eventually leading to the return of intermediate species like shrubs and small trees, culminating in the development of a climax community.

Explanation:

After a volcanic eruption, the grassland ecosystem can recover through a natural process known as succession. During this process, the area may experience several stages of recovery:

Primary succession, which occurs in lifeless areas where soil has to be created. This typically involves the growth of lichens and microorganisms that help in the breakdown of rocks into nutrient-rich soils.

Pioneer species like grasses and annual plants are usually the first to grow back. These species are important for stabilizing the soil and providing organic material as they die and decompose, thus enriching the soil further.

Over time, intermediate species such as shrubs and small trees like pine, oak, and hickory will establish themselves, building upon the changed environment and paving the way for a diverse ecosystem.

As the soil quality improves and the ecosystem matures, it will transition to a climax community, remaining relatively stable until the next disturbance.

To make sure all his heredity experiments were completed.

Explanation:

Genetic experiments, especially those investigating heredity and phenotypes take years to complete. This is one of the primary reasons genetic experiments (especially heredity) have never been conducted on humans. Scientists, instead, resort to a model system.

A model system is an organism that has been designed to make it easy for scientists to conduct experiments and reach reasonable conclusions.

Mendel chose the pea plant as a subject for its ability to replicate rapidly and produce multiple generations of offspring in a short time. This enabled him to study each generation's phenotypes and genotypes in detail. He could easily give sound conclusions on how a traitor gene travels down different generations.

Mendel chose pea plants for his studies because they reproduce quickly and produce many offspring, allowing for numerous experiments and evaluations. Pea plants also have easily identifiable traits and can be self-pollinated or cross-pollinated, providing controlled observations of crosses between different plants.

Mendel chose to work with pea plants for his studies on genetics because they are fast-growing and can produce many offspring in a short period of time. This allowed Mendel to conduct numerous experiments and evaluate several generations of plants. Additionally, pea plants have easily identifiable traits, such as height and flower color, making them ideal for studying inheritance. Furthermore, pea plants can either self-pollinate or be cross-pollinated, giving Mendel the ability to control and observe the results of crosses between different types of plants.
