As the number of coyotes increase, the numbe
r of beavers will decrease.
Observe the food web shown above. If the gray wolf became extinct,
what conclusion about the coyote population would not be valid
based on the relationships shown in the food web?
CLEAR ALL
Answer:
No, coyote will not become the apex predator.
Explanation:
No, coyote will not become the apex predator but greatly reduces the populations of foxes in order to reduce competition for available resources. Yes, The coyote population will decreases because t he gray wolf kills coyote to avoid competition for food resources. If another wolf is introduced to fit the same ni che, the coyote population will decrease because the wolf feeds on coyote. As the number of coyotes increase, the number of beavers will decrease because coyote feeds on beaver. If the gray wolf became extinct, the coyote population increases in that location due to no predator.
The total volume of plant cells is often significantly greater than the total volume in animal cells. The most reasonable explanation for this observation is that:_______
a. The total volume of plant cells is often significantly greater than the total volume in animal cells.
b. The most reasonable explanation for this observation is that plant cells have a much more highly convoluted (folded) plasma membrane than animal cells.
c. Animal cells are spherical, whereas plant cells are elongated. plant cells are capable of having a much higher surface-to-volume ratio than animal cells.
d. Plant cells contain a large vacuole that occupies much of the volume of the cell.
Answer:
d. Plant cells contain a large vacuole that occupies much of the volume of the cell.
Explanation:
The vacuole is a membrane-bound organelle which is often found in plant and fungi cells, as well as in certain bacteria, protists and animal cells. The vacuole is filled with water that forms a solution containing inorganic and organic compounds. The size of the vacuole may vary depending on the requirements of the specific cell type. In plant cells, vacuoles often occupy an important fraction of the overall cell volume and play key roles during growth and development, influencing diverse cellular functions ranging from photosynthesis to transpiration.

Which of the following is a main difference when comparing an animal cell and a plant cell?
Plant cells lack cell walls and form fixed shapes.
Animal cells have chloroplasts and mitochondria.
Animal cells lack cell walls and are irregular in shape.
Plant cells have one vacuole, produce chloroplast, but do not have mitochondria.
Answer:
I think the answer is animal cells lack cell walls and irregular in shape animals do not have chloroplast because they do not manufacture their own food so chloroplast is only found in plants plants have cell walls

How is a protein's shape related to its function?
Answer:
"A protein's specific shape determines its function. If the three-dimensional structure of the protein is altered because of a change in the structure of the amino acids, the protein becomes denatured and does not perform its function as expected."

In a nuclear reaction, the fuel pellets are split using what ? This also causes a chain reaction
Answer:
A nuclear reactor is driven by the splitting of atoms, a process called fission, where a particle (a 'neutron') is fired at an atom, which then fissions into two smaller atoms and some additional neutrons. ... Two examples of nuclear fissioning of uranium-235, the most commonly used fuel in nuclear reactors.
Explanation:
every time you see the ATP starburst or lighting symbol you should relate to it which concept
Answer:
The concept must be identified: that the energy currency for cells is ATP.
Explanation:
ATP is the abbreviation of the term Adenosine Triphosphate, the presence of its three phosphors and the dephosphorylation of them are the sources of chemical and electronic energy that our body and our cells need to be able to develop life.
The following reaction occurs in each ATP molecule used for energy purposes:
ATP + KINASE ----> ADP + P (inorganic)
Kinase is the enzyme that dephosphorylates the phosphorous molecules of ATP resulting in an ADP (adenosine diphosphate) and a free inorganic phosphorus.
Parents and their offspring are usually very similar, but always slightly different. For example, certain moths can have offspring with either dark or light wings. Almost everything else about the moths is nearly identical, but the wing color and pattern may look very different. If the moths live in a forest with trees that have very dark bark, which newborn moth would have a survival advantage, the light winged moth or the dark winged moth? A) The dark winged moth, because its color will help it fly away from predators. B) The light winged moth, because its color will help it fly away from predators. C) The dark winged moth, because its color will help it blend with the environment. D) The light winged moth, because its color will help it blend with the environment.
Answer:
The answer is A.
Explanation:
Moth with dark wings under the tree with dark bark have a higher chance of surviving as its wings protect them from predator due to similar colour features.
Answer:The answer is C.
Explanation:If the bark is dark, then a dark winged moth will blend.
Oxygen moves passively into our cells. Which cell will experience the slowest rate of movement of oxygen from outside the cell into the cell?
Answer:
The oxygen molecules move, by diffusion, out of the capillaries and into the body cells. While oxygen moves from the capillaries and into body cells, carbon dioxide moves from the cells into the capillaries. Carbon dioxide is brought, through the blood, back to the heart and then to the lungs

Which of the following is NOT a difference between normal cell division and cancer
cell division?
O Normal cells recognize signals that tell them to stop and start the cell cycle, but cancer cells
do not
Normal cells can invade other tissues, but cancer cells cannot
In normal cells, DNA is replicated correctly, but in cancer cells DNA is mutated
O Normal cells communicate with each other, but cancer cells do not
In normal cells, DNA is replicated correctly, but in cancer cells DNA is mutated. This is not a difference between normal cell division and cancer cell division. Thus, option B is correct.
What is Apoptosis?
Apoptosis is the process in which cells are destroyed or killed for the purpose of controlling their development and growth. The normal cells follow this process but the cancer cell do not response to it and keep growing.
Normal cells can invade other tissues, but cancer cells cannot. In normal cells, DNA is replicated correctly, but in cancer cells DNA is mutated.The difference between a normal cell and a cancer cell is that a normal cells undergo while cancer cells don't Also, normal cells respond to signals while cancer cells don't.
Cancer cells are grow in the absence of signals telling them to grow. Normal cells only grow when they receive such signals. Ignore signals that normally tell cells to stop dividing or to die which is the process known as programmed cell death.
Therefore, In normal cells, DNA is replicated correctly, but in cancer cells DNA is mutated. This is not a difference between normal cell division and cancer cell division. Thus, option B is correct.

If the top level consumers were eliminated from a food web would the populations in the levels below them increase without bounds
Answer:
That isn't true
Explanation:
That is not true bc if the top level consumers were removed from the food chain, then the level below would become the top level of the food chain. If that happened then the level below the NEW top level of the food chain would still be getting eaten and the food chain still goes on, just with one missing level.
