Answer:

<em>The correct option is A. variables</em>

Explanation:

The columns in any given table will be the list of the variables that are being applied to the experiment. In scientific method of research, a variable can be described as anything that can be changed in an experiment. However, a controlled group in an experiment is the one in which only one of the variable is manipulated.

The controlled experiment is used as a comparison for the experimental groups

agasfer [191]

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.

Romashka [77]

Answer:

nucleic acids.

Explanation:

The fusion of the sperm with the egg results in the formation of a zygote that develops into a new offspring. Twins refers to the two offspring which are a result of the same pregnancy. They are of two types. Monozygotic twins are a result of the single zygote (formed by the fusion of one egg with a single sperm) spiltting into two embryos forming the identical twins. Dizygotic twins are a result of two eggs fertilized with two different sperms forming the fraternal twins.

Identical twins are genetically simliar. The genetic material is derived from the same embryo and thus, the DNA of the identical twins are nearly identical. The spilitting of the embryo formed results in the separation of the same genetic material or identical DNA getting incorporated into the twins making them look alike in majority of the cases.
