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.

<h3>Effects of invasive species</h3>
  • Invasive species tend to drive away or kill native species.
  • Invasive species reduce the overall biodiversity of plants or animals in the ecosystem.
  • They cause economic loss through the loss of important native species.
  • They create nuisance in the environment and may be costly to get rid of.
  • They affect ecosystem equilibrium by causing species change.
  • They are usually difficult to manage.
