The administration method that takes the longest time for the drug to reach the brain is __________.
photoshop1234 [79]

Oral ingestion or swallowing is the administration method that takes the longest time for the drug to reach the brain. When using this method, the drug is swallowed through the mouth, moves to the stomach and then into the bloodstream before it can be transported to the brain. This means that it takes longer for a swallowed drug to start functioning than it does with other methods of administration such as injecting.

What happens to predator populations when prey populations are scarce? Why?
GenaCL600 [577]
When prey is abundant, predator populations increase because more young are able to survive. More predators kill more prey, which, along with food scarcity, decreases the population. When prey becomes more scarce, the predator population declines until prey is again more abundant. Therefore, the two balance each other.

Although the pyruvate dehydrogenase complex is subject io allosteric control, especially inhibition by reaction products, the ma
masya89 [10]

Answer: C

Explanation:

Pyruvate dehydrogenase complex (PDH) is covalently modified by phosphorylation by PDH kinase and dephosphorylation by PDH phosphatase.

The dephosphorylated form of the enzyme is active. Hence activators of PDH kinase like ATP, NADH and acetyl CoA inhibits the PDH reaction

PDH phosphatase is activated by Ca++, Mg++ and AMP; this will increase the rate of PDH reaction where as PDH kinase is inhibited by Ca++. When there is adequate ATP and acetyl CoA the enzyme is inhibited.

Explanation:

Specifically Luteinizing Hormone (LH)  along with the Follicle stimulating Hormone (FSH) released from pituitary gland gets attached to the receptors present in the cells of ovary and generate a series of chemical reaction or cascade of biochemical reaction in a cell (activation of secondary messengers like cAMP) to produce estrogen and progestrone that will help in follicle formation and ovum maturation.
