Answer:

A. Dihydrofolate reductase—methotrexate

Explanation:

Dihydrofolate reductase is an enzyme that reduces dihydrofolic acid to tetrahydrofolic acid. Methotrexateis its inhibitor. It interferes with folate metabolism by acting as a competitive inhibitor of the enzyme.

Since folateis necassary for rapid dividing cells, such as cancer cells, methotrexate can be used as anticancer drug that inhibits DHFR.

What is the primary function of the juxtaglomerular complex?
Vsevolod [243]

Answer:

Juxtaglomenular is a structure in the kidney which regulates the function of each nephron, the functional units of the kidney. The main function of the  juxtaglomerular cells is to secrete renin in response to:

Stimulation of the beta-1 adrenergic receptor

Decrease in renal perfusion pressure (detected directly by the granular cells)

Decrease in NaCl concentration at the macula densa, often due to a decrease in glomerular filtration rate

Explanation:

The juxtaglomerular apparatus is a specialized structure formed by the distal convoluted tubule and the glomerular afferent arteriole. It is located near the vascular pole of the glomerulus and a structure in the kidney that regulates the function of each nephron, the functional units of the kidney.

The trait of medium-sized leaves in iris is determined by the genetic condition PP′. Plants with large leaves are PP, whereas pl
dsp73

Answer:

20 large size leaves plants

40 medium sized leaves plants

20 small sized leaves.

Explanation:

PP = large leaves

P'P' = small leaves

PP' = medium leaves

PP' was crossed with another PP' plant:

PP'   x   PP'

progeny = PP, 2PP', and P'P'

PP = 1/4  x 80 = 20 large size leaves plants

PP' = 1/2 x 80 = 40 medium sized leaves plants

P'P' = 1/4 x 80 = 20 small sized leaves.

<em>Hence the phenotypes would be:</em>

<em>20 large size leaves plants</em>

<em>40 medium sized leaves plants</em>

<em>20 small sized leaves.</em>
