Answer:
B. Estrogen binds to specific receptors inside many kinds of cells, each of which have different responses to its binding.
Explanation:
Estrogen is a lipid-soluble steroid hormone and binds to its receptors present inside the target cells. Estrogen binds to specific receptors in different types of cells. Binding of estrogen to a specific receptor in a cell would initiate the specific cellular response. Likewise, binding of estrogen to its receptors in some other cell type would generate a different cellular response. For example, binding of estrogen to transcription factors in the cells of mammary glands may stimulate cell division and differentiation to trigger the development of mammary glands at puberty in females.
Answer:
Some may cause diseases.
Explanation:
Eubacteria and Archaebacteria differ by a few characteristics:
- DNA replication
- Transcription
- Type of translation machinery
- Cell wall structure
It has been found that these do reproduce quickly and sometimes in humans. It may cause some danger in some situations as cholera and vibrio are virulent and dangerous diseases to humans.
In other aspects it does not pose a threat to human health in the case of <em>Lactobacillus. </em>
Archaebacteria on the other hand is not known use humans as a host but they may infect other Eubacteria and cause them to be negatively affected.
Fast reproduction/division rate means that the infection of the bacteria cannot be slowed down or stopped before the organism it has taken over becomes affected.
The answer to this question in the phase Interphase when the chromosomes replicate to form joined sister chromatids , and also the dna gets replicated
Evolution; one organism adapting to better survive new conditions.
