Answer:
The current decrease in elephant populations is primarily due to illegal poaching, demand for Ivory products, and factors associated with human population growth.
The brain stem consists of the ________. Group of answer choices midbrain, medulla, and pons cerebrum, pons, midbrain, and medulla midbrain only pons, medulla, cerebellum, and midbrain
Hey there! I'm happy to help!
The cerebellum is in the back of the brain and it helps with balance and reflexes, but it isn't part of the actual brain stem, so that is not the right answer choice.
The cerebrum is the front part of the brain made up of the many different lobes. Its ultimate goal is to help with thought, movement, and language. This is not part of the brain stem.
The brain stem consists of the midbrain, medulla, and pons. The midbrain is the uppermost part with the pons below it and the medulla oblongata below the pons.
The midbrain is important for functions such as eye and body movement. The pons aids with body signaling and the medulla oblongata also aids with reflexes and involuntary actions (as it is close to the cerebellum). The brain stem as a whole helps with respiration, heart rate, and blood pressure.

As an ecosystem goes through succession, which of the following is likely to
happen:
A. Increase in biodiversity
B. Ecosystem will trigger Secondary Succession
C. Decrease in competition
D. Decrease in niches
Answer:
A
Explanation:
succession is replacement of one ecosystem by another so this cause increase in biodiversity
When an ecosystem goes through succession, the biodiversity of the ecosystem tends to increase. Thus, the correct option is A.
What is Succession?Succession may be defined as the gradual and continuous replacement of one community by another community over a long period of time.
Succession is always taking place by a better competitor. The first arrived species is known as the Pioneer species. Intermediate species are known as seral communities, while the highest species is known as the Climax species.
Overall, it increases the biodiversity of the region.
Therefore, the correct option is A.

from facilitated diffusion?
A. Facilitated diffusion does not use protein
channels.
B. Active transport requires energy.
C. They are very similar processes.
Answer:
B
Explanation:
active transport requires energy (ATP) where as facilitated diffusion is a passive process meaning it doesn't require energy.

whats the difference between the lipid structure and the carbohydrate structure
Lipids are an important element of the cell membrane. The structure is usually composed of a glycerol backbone.
Carbohydrates, it's very literal: are “hydrates of carbon” and possess the general structure of C(n)H(2n)O(n).
Lipid molecules comprise more energy per gram than carbohydrates: close to two times as much.Carbohydrates are more readily ingested than lipids and discharge their energy more quickly. Monosaccharides and disaccharides are water-soluble and are less complicated to move to and from storage places than lipids.Animals manage to apply carbohydrates fundamentally for short-term energy storage, while lipids are applied more for long-term energy storage. Carbohydrates are stored as glycogen in creatures while lipids are stored as fats. In plants, carbohydrates are stored as cellulose and lipids as greases.Lipids have less impact on osmotic force inside a cell than complex carbohydrates.what will happen if all snakes are killed
If all snakes are killed the prey population will grow and overlap effects would ripple through the ecosystem and cause considerable damage. the prey population that snakes feed on would grow, and the predators that feed on snake will die out.
Lipid (fat) breakdown begins in the
a. stomach
b. ileum
c. jejunum
d. duodenum
Respuesta B.
Explanation:
(((First part of the small intestine))). It connects to the stomach. The duodenum helps to continue digesting food that comes from the stomach. It absorbs nutrients (vitamins, minerals, carbohydrates, fats, proteins) and water from food so that the body can use them.
which orgnaisms transform nitrogen to a form that is useful to plants
Answer:
Nitrogen-fixing bacteria are prokaryotic microorganisms that are capable of transforming nitrogen gas from the atmosphere into “fixed nitrogen” compounds, such as ammonia, that are usable by plants.
Explanation:
Answer:
Nitrogen fixing bacteria
Explanation:
Atmospheric nitrogen is in the form of
N
2
. This molecule is exceptionally stable and unable to be used by plants. The Lewis dot structure of
N
2
is
: N :::N:
The triple bond between the two nitrogens is very strong. However nitrogen fixing bacteria can attach to the the unused paired electrons on the outside of the nitrogen molecule. The bacteria use the energy from the broken bond for life functions and produce Nitrates and Nitrites as by products. Nitrates (
N
O
3
) and nitrites (
N
O
2
) can be used by plants for nutrition.
Nuclear fusion produces _____________ nuclei.
Answer:
it produces heavier nucleus.
Explanation:
in nuclear fusion two light nuclei fuse together to form a heavier nucleus.
In order to test the effects of a new drug, you isolate the messenger RNA molecules from both treated and untreated eukaryotic cells and separate them according to size using gel electrophoresis. In each lane of the gel, the shorter RNA molecules migrate more quickly through the gel and end up near the bottom of the gel while the longer RNAs migrate more slowly and remain near the top.
The samples that were loaded into each of the four lanes are as follows:
Lane 1: the primary RNA transcripts isolated from the nucleus of untreated cells
Lane 2: the primary RNA transcripts isolated from the nucleus of cells treated with the drug being tested
Lane 3: RNA isolated from the cytosol of untreated cells
Lane 4: RNA isolated from the cytosol of cells treated with the drug being tested
Which of the following conclusions is most likely to be CORRECT?
A. These results suggest that the drug affects RNA processing.
B. These results suggest that the drug digests DNA.
C. These results suggest that the drug inhibits DNA replication.
D. These results suggest that the drug contains a protease that targets this gene product.
E. These results suggest that the drug inhibits post-translational processing of this gene.

How is nuclear energy generated?
Answer:
Nuclear energy is generated either by Fission of a nucleus into two or more fragments , or by Fusion of two nuclei into one. The nuclear energy is used to superheat steam and then drive a rotor axle inside a generator and then generate electricity.
Answer:Nuclear power comes from nuclear fission
Explanation:Nuclear power plants heat water to produce steam. The steam is used to spin large turbines that generate electricity. Nuclear power plants use heat produced during nuclear fission to heat water. In nuclear fission, atoms are split apart to form smaller atoms, releasing energy.
