I'm not saying this is for sure but this is what I'm answering for mine thanks to a yahoo answers. d) Migrating bird populations and the carry capacities of local animal species. You don't have to award points or anything I just wanted to try and help. This is what I put on another persons questions as well. I hope this is helpful and accurate. I'm sorry if it is not.
Answer:
B. They belong to the same species and C. They live in the same area.
Explanation:
This is an educated guess. If you think about it, if there was a population of humansss, we dont have the same parents nor the exact genes so to only two that make sense is those to (^ω^)
Answer:
If the shape of an enzyme changes then the enzyme will no longer be able to perform its function.
Enzymes can be described as bio-catalysts which usually speed up a chemical reaction. Each enzyme has a particular substrate which fits into the active site of the enzyme. Every enzyme needs a particular temperature and pH for its functioning. If the shape of an enzyme changes, then it will no longer be able to perform its function and will become denatured.
Answer: May occur in response to growth factors
Explanation:
Hyperplasia is increased cell production in a normal tissue or organ. Hyperplasia may be a sign of abnormal or precancerous changes. This is called pathologic hyperplasia.
Pathologic hyperplasia can occur in response to hormones and growth factors (for example in endometrial hyperplasia, the hyperplasia caused by excessive hormonal stimulation or growth factors acting on target. Thus, patients with hyperplasia of the endometrium are at increased risk for developing endometrial cancer.)
Hyperplasia is also an important response of connective tissue cells in wound healing, in which proliferating fibroblasts and blood vessels aid in repair.
Under normal circumstances, growth factors are responsible for the hyperplasia. Stimulation by growth factors is also involved in the hyperplasia that is associated with certain viral infections, such as papillomaviruses, which cause skin warts and several mucosal lesions composed of masses of hyperplastic epithelium.
Other important concepts to note:
Dysplasia refers to abnormal changes in the size, shape, and organization of mature cells. Compensatory hyperplasia enables organ regeneration and is a normal process: hyperplasia is not normal. Pathologic hyperplasia increases cell number. Hypertrophy is an increase in the size of cells and consequently in the size of the affected organ.
