Amutation that inhibits ras from hydrolyzing gtp will
a. block association with the sos1/grb2/shc1 complex.
b. inactivate p53.
c. block elk1 location in the mitochondria.
d. bind erk to the igf1 receptor.
e. result in permanent activation of ras.

The correct answer is option e. "result in permanent activation of Ras".

Explanation:

Ras function is regulated by the GTP/GDP cycling rate, in a way that Ras is inhibited by the substrate GDP. Once Ras hydrolyzes GTP, GDP is produced and Ras is inhibited by GDP. A mutation that inhibits Ras from hydrolyzing GTP, would lock Ras in a permanently activated state because no GDP would be produced and there will be no substrate to inhibit Ras.

it would be f

explanation:

white blood cells or wbc s are mainly 2 types-

1.agranulocytes

2.granulocytes

the monocytes or macrophages of agranulocytes , dendritic cells which are accessory leucocytes, and b cells which is one type of lymphocytes   identify the antigens present on the pathogen's surface. these three cells are called antigen presenting cells(apc) which are phagocytes and destroy the antigens by secreting antitoxins. besides this leukocyte is always plays vital role in the immunity of the body.
