as a pesticide since the 19th century used especially during World War I to control typhus and malaria
vectors. The chemical had application as
a pesticide both in homesteads and in agriculture. However, it has been banned in the USA due to claims of its carcigonecity and its negative environmental impact. DDT has been shown to harm most arthropods indiscriminately.

Answer:
The options
A)Damage to cellular mitochondria
B)Increased ATP levels
C)Activation of the p53 protein
D)Apoptosis
The CORRECT ANSWER IS D
D)Apoptosis
Explanation:
The extrinsic pathway of apoptosis includes extracellular signaling proteins which adhere to cell surface molecules known aa death receptors which in turn activates apoptosis.
The aftermath activates endonucleases prompting division of DNA and ultimately cell death.
Apart from the TNF and Fas ligand, primary signaling molecules also promotes the extrinsic pathway, examples of such are the TNF-related apoptosis-inducing ligand (TRAIL); the cytokineinterleukin-1 (IL-1); and lipopolysaccharide (LPS), the endotoxin located in the outer cell membrane of gram-negative bacteria while the activation of the p53 protein, and decreased ATP levels in the intrinsic pathway results in DNA damage.
Answer:
XnY
Explanation:
II-2 is a male so the genotype must have a Y in it. Majority of the other options do not have Y, so they are incorrect. Because the individual is male, the father has passed a Y chromosome, while the mother has passed an X chromosome. The X chromosome is Xn because the mother is hemolytic, which is a recessive trait. So both the mother's X chromosomes carry the hemophilia trait.
