follicle-stimulating hormone is a pituitary hormone that acts on the follicle cells of the ovary to trigger the synthesis of cyc
irinina [24]

Answer:

Cells grown in culture tend to adhere to each other, through adhesins, so they are able to communicate with each other. They form gap junctions that allow the cytoplasm of the cells to exchange some molecules such as cyclic-AMP associated molecules in this case.

Therefore even though the FSH binds to the receptors on the ovarian follicle cells only (since these are the cells that bear the receptors for the hormone on their surface), the pathway and associated molecules for secondary messengers can diffuse across the across the gap junction into other cells, including those of the cardiac cells, hence inducing some contraction in these cells, as they respond to the secondary messengers.

Which statement best explains why muscle cells and skin cells do not look and act the same?
Anon25 [30]
The statement which explains why muscle cells and skin cells do not look and act the same is this: THE GENES IN EACH TYPE OF CELL ARE BEEN EXPRESSED DIFFERENTLY. 
All the cells in human's body has the same set of genes, this is because, all the cells in the body originated from a single fertilized egg. Even though all the cells in the body has the same origin, they are different from one another because, the cells use the same set of genes differently.

Did the Florida Panther become endangered because of natural selection, genetic drift, or gene flow?
Natalija [7]

Answer:

ALL OF THE ABOVE

Explanation:

Genetic Drift are the changes in allele frequency of a population that result from RANDOM survival or reproduction of individuals with certain characteristics.  Survival or reproduction of those individuals in the face of some environmental change is a matter of LUCK or CHANCE, not because of their phenotype or genotype.

While in Natural selection, the environmental events that affect a population are likely random, but the survival or reproduction of the individuals depends on their phenotypes and genotypes.

Meanwhile, Gene flow is the movement of genes into or out of a population. Low gen flow can lead to low genetic diversity.

Low population which can cause low genetic diversity, poor habitat conditions and habitat loss, road deaths, and commercial development in panther range are constant threats to the Florida Panther's survival.

All these causes are related and therefore affects the Florida Panther.
