Adult tigers look very different from a fertilized tiger egg cell.  A fertilized tiger egg cell is only a zygote. As it grows it developes stem cells that create seperate tissues. These tissues grow into organs and organ systems that form a body.

What effect would hypotension have on the capillary hydrostatic pressure gradient and net filtration pressure?
Alla [95]

Hypotension will  cause the interstitial fluid hydrostatic pressure to increase and capillary hydrostatic pressure to decrease. The net filtration pressure will be reduced favoring the absorption .

Explanation:

Hypotension refers to reduced blood pressure. Decrease in blood pressure results in reduced filtration pressure on capillary walls. This reduces the filtration of water and solutes into the tissue fluid but will favor the movement of water from tissue to blood. So we can say that net filtration pressure will be reduced.

Three examples of selective breedings, explain?
ANEK [815]

Artificial Selection is a form of selection in which humans actively choose which traits should be passed onto offspring. Humans have used selective breeding long before Darwin's Postulates and the discovery of genetics. Farmers chose cattle with beneficial traits such as larger size or producing more milk, and made them breed; and although they may have known nothing about genes, they knew that the beneficial traits could be heritable. The farmers selected for certain traits in their cattle and probably noticed that the offspring were becoming more and more productive with each generation. Scientists study these traits and spend a lot of time calculating how heritable these traits can be. The more these traits are expressed in the offspring (i.e. size, milk production, etc), the more heritable these traits are said to be. Hunting is also a form of artificial selection, with the genes that humans "want" (i.e. - the biggest buck with the most points, the largest fish, etc.) being removed from the gene pool, allowing the less "wanted" genes to pass on to the next generation by increasing their odds of mating when compared to the hunted specimens.

Hope this will help.

Which nerves are the hair cells in contact with?
AlekseyPX

Answer:

Auditory nerve

Explanation:

Hair cells form synapses with bipolar neurons whose axons form the auditory nerve. Tips of the outer hair cells are attached directly to the tectorial membrane. When the inner hair cells move they make contact with the overhanging tectorial membrane

Fun fact: Hair and nials are made out of the same things!
