Answer: The option that is true regarding Carl's use of substances is D) All of these choices are true.
Explanation: All of the choices provided about Carl's use of substances are true. First, he shows that he has characteristics of addictive behaviour when <u>he denies that he has a problem with drug use, when he boasts about his capacity to drink alcohol, and when he dismisses the risks of mixing alcohol and drugs.</u> Moreover, Carl has a substance abuse problem<u> he desires to drink and use drugs day and night and even to mix the substances</u>. He also has a substance dependence problem because, <u>when he is not drinking, he is using "speed" and, when he needs to sleep, he takes Valium.</u> In that way, Carl has both substance abuse and substance dependence problems and he also behaves as an addict.
When cyclic AMP phosphodiesterase is inhibited in a muscle that is stimulated by epinephrine,there will be a crucial effect of making the phosphorylase kinase to remain active,this active state of the phosphorylase kinase is because the associated protein kinase A will not be deactivated any longer.
Epinephrine signaling pathway has varying steps,but the preceding step occurs when the associating hormone binds to the receptor of the epinephrine in the cell surface,the receptor then changes shape when the hormone triggers it,this makes the receptor to move to it's active form. GDP( guanosine diphosphate) is released after the G protein ( guanine nucleotide-binding proteins) binds to the receptor that is activated,the G protein then takes up a molecule of GTP (guanosine triphosphate) .

Answer: Sorry umm i cant see the problem quite clearly
Explanation:
sorry
Answer:
sin a=-4/5
we have sina=perpendicularp/hypotenuseh=-4/5
let p=-4k
h=5k
by Pythagoras theorem
h²=p²+b²
(5k)²=(-4k)²+b²
25k²-16k²=b²
(3k)²=b²
b=√(3k)²=3k
now
cos a =b/h=3k/5k=3/5
