Answer:
Any of the answers are correct. This question is completely opinionated (I chose no).
[If you limit your interpretation of the biological species concept to only what happens in nature, lions and tigers are separate species. In contrast, if you consider what is possible with human intervention, you could argue that lions and tigers are not separate species since they can be crossed to form fertile ligers.
The biological species concept is one of over 20 different species concepts that attempt to put nature into human-constructed categories. Most biologists would agree that the challenge of defining species has still not been elegantly solved.]
Basically when water goes over the earth it corrodes it and in that way shapes the earth's surface. The hydrosphere corrodes the gyoshere at Havasu Falls.
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.
Answer:
Their genes are expressed differently.
Explanation:
Nerve cells and skin cells have the same genes, but the reason they're different is because of how those genes are expressed and used. Some genes may not be of importance of skin, but they might have an affect on the neural pathways.
