Answer:
the native species will go extinct
Explanation:
Final answer:
Invasive species, like the birds in the nonnative habitat, can compete with native species for resources, leading to a decline in native populations.
Explanation:
Invasive species, such as the birds in the nonnative habitat, can have various effects on native species that share the same resources. One of the most likely effects is competition for resources. Invasive species often out-compete native species for food, nesting sites, and other essential resources, which can lead to a decline in native species populations. For example, if the invasive birds consume the same food sources as the native birds, it may result in food shortage and decreased reproductive success for the native birds.

Name a product in your home that affects the ocean. What is its impact, and how can you change it?
Plastic has a major effect on the ocean's environment. fish and other ocean creatures can get stuck in the plastics and kill them. It as well takes a long time to decompose, creating an even larger risk of ocean creatures getting stuck or even mistaking the plastic for food and choking. You can change this by switching to recyclable material like paper bags.
Hope this helps!
Explain the difference between speed, velocity and acceleration. Give an example of each.
speed is the rate that something is able to move or operate, velocity is the speed of something in a given direction, and acceleration is somethings capacity to gain speed within a short time.
examples.
speed: 45 mph or cleaning a room in 10 mins
velocity: 75 mph
acceleration: dropping a ball, speeding up, slowing down, turning
Speed measures the rate of distance traveled, velocity includes direction, and acceleration is the rate of change of velocity. Average speed is based on total distance while the magnitude of average velocity is based on total displacement.
Understanding the difference between speed, velocity, and acceleration is crucial in physics.
Speed
Speed is a scalar quantity that measures how fast an object is moving. It is the distance traveled per unit of time and does not include direction. For example, if a car travels 60 kilometers in 2 hours, its speed is 30 kilometers per hour (km/h).Velocity
Velocity is a vector quantity that specifies both the speed of an object and the direction of its motion. For example, if a car travels 30 km/h north, its velocity is 30 km/h north. The difference between speed and velocity is that velocity includes direction, whereas speed does not.Acceleration
Acceleration is the rate of change of velocity. It can be due to a change in the object's speed, direction, or both. For example, if a car speeds up from 30 km/h to 60 km/h in 10 seconds, its acceleration is (60 - 30) / 10 = 3 km/h per second.Average Speed vs. Magnitude of Average Velocity
There is a distinction between average speed and the magnitude of average velocity. Average speed is the total distance traveled divided by the total time taken. On the other hand, the magnitude of average velocity is the total displacement (change in position) divided by the total time taken.For instance, if you travel 100 km to city A and back to the starting point in 4 hours, your total distance is 200 km, making your average speed 50 km/h.However, your displacement is zero because you end up where you started, so the magnitude of your average velocity is 0 km/h.

Brendan made a chart to categorize the characteristics of animals. which phrase should be written in the column titled “sometimes”?
A. are multicellular
B. have membrane-bound organelles
C. produce their own food
D. display an asymmetrical body plan
Answer:
D. display an asymmetrical body plan
Explanation:
Most of the animals have bilateral symmetry but sometimes animals show asymmetrical body plan.
Rest of the options are wrong.
Animals are always multicellular and there is no exception to this fact. So, if we will write sometimes animals are multicellular, it will be a wrong statement.
Animals are eukaryotic organisms so it means that they must have membrane-bound organelles .The organisms which do not have membrane-bound organelles are known as prokaryotes but animals are eukaryotes. So B statement is wrong.
All the animals are heterotrophs that means that animals cannot produce their own food in any situation so statement C is also wrong.
Answer:
Display an asymmetrical body plan

Which molecules are reactants in cellular respiration? Cellular respiration uses oxygen as a reactant and photosynthesis does not.
Answer
Hi,
The reactants in cellular respiration are oxygen and glucose
Explanation
The process of cellular respiration takes place in the mitochondria. The reactants are oxygen and glucose and the main product is ATP energy. The waste products of cellular respiration are carbon dioxide and water. In photosynthesis, the reactants are light energy, water, carbon dioxide and chlorophyll to produce oxygen, water and glucose.
Best wishes!
Final answer:
In cellular respiration, oxygen and glucose are reactants that combine to produce ATP, with carbon dioxide and water being byproducts. This process primarily takes place in the mitochondria and is vital to energy production in cells.
Explanation:
Reactants in Cellular Respiration:
In the biological process of cellular respiration, oxygen and glucose are the primary reactants. Oxygen is essential for the breakdown of glucose; a molecule that cells derive from food which provides the necessary chemical energy. This process is critical for producing ATP (adenosine triphosphate), the energy currency of the cell, and occurs primarily within the mitochondria.
The overall chemical reaction for cellular respiration uses one molecule of glucose (C₆H₁₂O₆) and six molecules of oxygen (O₂) to produce energy. This reaction yields six molecules of carbon dioxide (CO₂) and six molecules of water (H₂O) as waste products. It reflects the inverse of photosynthesis, which utilizes carbon dioxide and water to produce glucose and oxygen.
It's noteworthy that every molecule involved in these processes is conserved and recycled in nature, maintaining a balanced and continuous cycle of matter and energy among organisms.

Answer:
A. They provide a way to study the overall age demographics of a population.
Explanation:
" it's a summary of the number of individuals of each age in the population. Age structure is useful in understanding and predicting population growth."
Answer: Hence, Option 'a' is correct.
Explanation:
Age structures is the proportion of population that belongs to different age group.
The purpose of age structure is that it provide a way to study the overall age demographics of a population.
With the age structures, we get to know about the prevailing age groups mostly present in particular area or country or world wide.
Hence, Option 'a' is correct.
What does evolutionary theory suggest about the unity and diversity of life?
all species-living and extinct-are united by descent from anciet common ancestors, and exhibit diversity due to natural selection and adaptation
Within each eon, identify major events and the types of life that dominated the Earth during the time.
There has been two eons in the Earth's geologic history so far, the Precambrian eon, and the Phanerozoic eon. The eons are the basic and by far longest units on the geological time scale, spreading over hundreds of millions of years.
The Precambrian eon is the eon that starts with the formation of the Earth, up until the development of multi-cellular organisms. A very important event in this eon can be considered the formation of the Earth's oceans, which later enabled the conditions for the development of life. The organisms that dominated this eon are the one cellular organisms.
The Phanerozoic is the eon in which the multi-cellular organisms started to develop and evolve. This eon started with the end of the Precambrian eon, 543 million years ago up until the present. A very important event in this eon is the change of the composition of the atmosphere, which enabled the terrestrial life, as well as the better living conditions for the marine life. It is very hard to choose a dominant form of life in this eon, but worthy of mentioning are the plants, the sinapsids, dinosaurs, mammals, fish.

issues related to blood donation
In addition to being very confused, our bodies work systematically. When there is a lack of blood, it begins to produce new blood. As you give blood, the blood cells are renewed and you get younger. Bone marrow prevents oiling. The risk of heart attack is reduced by 90%. The rate of fat in the blood drops, your headache, stressful mood, your blood pressure goes. Your cholesterol and sugar levels remain in balance. Each time you give blood, a screening test is performed. Thus, HIV, Hepatitis B, Hepatitis C and syphilis scan will be passed. And of course, the happiness you have gained by giving life to the people you do not know hiç
Unless alcohol is taken twelve hours before giving blood; fifty kilograms and over, between the ages of 18 and 65, anyone with a normal hemoglobin measurement can donate blood. Men can donate blood four times a year in ninety days, women can donate blood once in a hundred and twenty days. drug addicts, heart attackers, infectious diseases, very low and high pulse, blood coagulants, excessive alcohol consumption of organ and tissue transplantation, those with flu, blood-expressing drug users, those with body temperature above 37.5 can not donate blood. Blood don't stand up immediately after the process, ten minutes to rest, do not carry heavy with your arm, blood juice and water for the first four hours to consume plenty of sports activities to exhaust the body and things like not to enter the sauna.

why do offspring produced through sexual reproduction show traits of each parent?
it depends on the sperm because the sperm goes through and it either takes the female sperm or the Male sperm to activate faster. The sperm from which parent basically gives the offspring their traits. I hoped this helped
Sexually reproducing organisms have two sets of genes for every trait. Offspring inherit one allele for each trait from each parent, thereby ensuring that offspring have a combination of the parents' genes.
What are the characteristics of genes?A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins.
Type I genes tend to be involved in immune response or sensory receptors while type III genes are involved in cell to cell signalling and type II genes are a complex mix of all three types.
Your genome is inherited from your parents, half from your mother and half from your father. The gametes are formed during a process called meiosis.

What two factors keep Earth in orbit and around the sun and the moon in orbit around Earth?
A)
force and speed
B)
mass and distance
C)
gravity and inertia
D)
gravity and distance
Final answer:
Gravity and inertia are the two factors that maintain the orbits of the Earth around the sun, and the moon around Earth, providing the equilibrium for their movements in space.
Explanation:
The factors that keep the Earth in orbit around the sun and the moon in orbit around Earth are gravity and inertia. Gravity is the force of attraction between two masses, which in this case are Earth and the sun, and Earth and the moon. Inertia is the tendency of an object to remain in uniform motion unless acted upon by an external force. The balance between gravity pulling the celestial bodies towards each other and inertia trying to keep them moving in a straight line is what keeps them in their respective orbits.

explain how local geography can influence the local pattern of precipitation
If there is a high undulation such as a mountain in the local region there will be high precipitation on the windward side of the mountain and low precipitation on the leeward. This is because a mountain forces the winds towards the cooler upper atmosphere. The moisture in the wind condenses and precipitates. As the winds descend into the leewards side most of the moisture has been drained out.

As far as my knowledge goes, the yellow area is mitosis, and mitosis is a process of cell division which results in two new nuclei (each containing a complete copy of the parental chromosomes)
D. the cell is dividing
Answer:
D. The cell is dividing.
Explanation:
Cell cycle is a series of events that leads to development of two daughter cells from a parent cell. The two main phases of cell cycle are interphase and mitosis. Interphase is the longest phase of cell, while mitosis takes much less time than interphase.
During interphase cell prepares for division and replicates its DNA, while mitotic phase involves actual cell division. During mitosis, division of nucleus and cytoplasm takes place to form two daughter cells.
Thus, the correct answer is option (D).

What was the predator of the stickleback in loburg lake?
A. Frogs (tadpoles)
B. Dragon flies (larva)
C. Humans
D. Moose
The correct answer is - C. Humans.
The stickleback in Loburg Lake, Alaska, is not a native species of the lake. It is thought that this fish was introduced to this lake somewhere between 1984 and 1989. The reason for this kind of suggestion is that the stickleback in this lake had full armor like the stickleback in the seas, which is not something found among the lake populations of this species. Also, the full armor had gradually been reducing with each new generation, and in the present, the stickleback in this lake looks totally the same as the other lake populations.
The stickleback did not had any predators in Loburg Lake, thus the losing of the full armor as it was not needed, instead the stickleback was the predator. But even though it didn't had a predator in the water, the humans became its predator through the recreational fishing that takes place on this lake.

An atom is the smallest unit of matter that retains properties of an element. It consists of a nucleus of protons and neutrons, surrounded by electrons. Atoms are fundamental to all matter and can convert matter into energy.
An atom is the smallest unit of ordinary matter that retains the properties of a chemical element. Here's how an atom works:
Structure: An atom consists of a central nucleus surrounded by a cloud of negatively charged electrons.Nucleus Composition: The nucleus is composed of positively charged protons and electrically neutral neutrons.Electrons: Electrons orbit the nucleus in various energy levels and are attracted to the nucleus by the electromagnetic force.Subatomic Particles: Atoms are made up of protons, neutrons, and electrons. Protons have a positive charge, neutrons have no charge, and electrons have a negative charge.Energy Conversion: Matter can be converted into energy, as described by Einstein's equation, E=mc², which shows that a small amount of mass can be converted into a large amount of energy.Atoms are incredibly small, with typical sizes around 100 picometers. Despite their size, they are the fundamental building blocks of matter, making up all solids, liquids, gases, and plasma in the universe.
