Hello there ^ _ ^
I believe the answer is : A - Evolution
Good luck!
Answer:
Genetic drift is change in allele frequencies in a population from generation to generation that occurs due to chance events. To be more exact, genetic drift is change due to "sampling error" in selecting the alleles for the next generation from the gene pool of the current generation.Explanation:
Answer: a. True
Explanation:
Glomerular filtrate is formed by the difference in force of hydrostatic and osmotic pressure. This physical force involves:
Bowman's capsule hydrostatic pressure: This includes the pressure that develops in the Bowman's capsule against the fluid to be filtrated expelled out by the glomerulus.
Glomerular hydrostatic pressure: The glomerulus is the main site of production of filtrate. It is higher than the average blood capillary hydrostatic pressure. It allows the water and solute molecules to be filtrated out of the plasma membrane.
Colloid osmotic pressure: The osmotic pressure which is generated by the large molecules is the colloid osmotic pressure. It is created by the plasma proteins. This pressure draws water from the glomerulus.
Answer:
Hormones are controlled by a
(negative)
feedback system between the glands that produce this hormone and the concentration of blood calcium ions. If the level of ions is
(low)
,hormone secretion is increased. This causes resorption by cells called
which releases both calcium and phosphate ions into the blood stream.
Explanation:
Negative Feedback a the process in your body that helps to maintain Homeostasis. If some variable changes a value in your body, like your ion levels, your glands produce a hormone that causes resorption by cells. This releases both calcium and phosphate ions into the blood stream and therefore your ion levels go back to normal.
Hope this helps!
