Mars2501 [29]

The premises that reinforce the thesis "the human drift", statement are A) 1, 2, and 3.

  • The objective of a thesis statement, which often consists of one or two phrases, is to lead the author so that he or she doesn't lose focus while also educating the reader about the author's viewpoint and the topic of what will be read by the man.
  • The thesis statement in the "The Human Drift" passage by Jack London reveals that the topic under discussion will be how humans have improved upon and become more proficient at killing.
  • The thesis statement should be supported and reinforced by the premises. In this instance, the thesis statement will be well supported by any premise that demonstrates the development of man's killing techniques and the diversity of his prey.
  • Those are the exact things that sentences 1, 2, and 3 do. They discuss how man kills to maintain his dominance over other species, how killing tools were created perhaps too early in man's history, and how man has improved to the point where he can kill germs.

Hitman42 [59]

Answer:

Actin depolymerizing factor binds F-actin cooperatively and induces a conformational change in F-actin that causes it to twist further and become more destabilized. This twisting causes severing of the bond between actin monomers, depolymerizing the filament.

Explanation:

Actin filament depolymerization ensures the turnover of actin filaments within these structures and maintains a pool of actin monomers that permits the continual restructuring and growth of the actin cytoskeleton. ADF/cofilin influences actin filament turnover.

Answer:

•The dodder plant is parasitic.

A parasite cannot survive or reproduce without its host because it depends on it. The dodder plant is parasitic to the potato plant because it derives its nutrition from the potato plant which is the host. The potato plant is denied its nutrient and therefore grows weakly below its maximum potential. The dodder plant gains while the potato plant is negatively affected- that’s parasitism relationship.
