The answer is ‘behavioral isolation’. It is a form of
sympatric speciation - which occurs even when
species live in the same habitat. In this case,
the individuals in the population are isolated by differences in mating and probably different mating rituals.
P450scc or cholesterol side chain cleavage enzyme is an enzyme that converts cholesterol into pregnenolone (the precursor for steroids). The kinds of steroid hormones are mineralocorticoids (i.e. aldosterone) glucocorticoids (i.e. cortisol), and sex steroids (i.e. testosterone, estrogen). In the event where P450scc is blocked, then there will be no production of mineralocorticoids, glucocorticoids, and sex steroids. There will be no production of aldosterone, cortisol, estradiol, testosterone, and progesterone. This disease is called Lipoid Congenital Adrenal Hyperplasia.
Answer:
Proteins, Liver, Osmotic, Fluid, Into The Blood, Decrease.
Explanation:
Blood is considered a colloid because it contains proteins in the plasma.
Most of these are produced by the liver.
Collectively, these substances exert osmotic pressure and prevent the loss of fluid from the blood as it moves through the capillaries.
The pressure exerted by the plasma proteins is called colloid osmotic pressure.
This force is responsible for moving fluids into the blood and preventing excess fluid loss between blood capillaries and the interstitial fluid.
If plasma protein levels decrease, colloid osmotic pressure will decrease.
I hope this answer helps.
Answer:
Blood vessels constrict
Explanation:
On seeing danger, impulses are sent to the adrenal medulla. It responds by secreting adrenaline into the bloodstream. This results in the following:
- Increased heartbeat
- Diversion of blood from alimentary canal and skin to skeletal muscles.
- Increased breathing rate and depth
- The liver releases more glucose.
These changes increase energy production especially in the skeletal muscles and prepare animal for sudden fight or flight.
