Prophase

Explanation:

During this phase the nuclear membrane disappears and chromosomes appear. Centrioles move to the opposite corners and spindle fibre formation starts.

No it’s interphase.

During interphase, the cell acquires nutrients, creates and uses proteins and other molecules, and starts the process of cell division by replicating the DNA. That is the first stage.

A catabolic pathway may be which of the following? a. a set of reactions that combine monomers into larger, more energy-rich pol

KiRa [710]

Answer:

The correct answer is option c. "a set of reactions that release energy that can be used to drive cellular work".

Explanation:

Catabolism is a part of metabolism at which molecules are broken down into smaller units in order to release energy that could be used in other reactions that drive cellular work. A catabolic pathway follows catabolism criteria. Catabolic pathways are the opposite of anabolic pathways, at which large molecules are synthesized with the requirement of external energy supply.

Radda [10]

Answer:

Prenatal.

Explanation:

The sexual reproduction may be defined the process of fusion of the male sperm and female ovum that leads to the formation of the zygote. Zygote is diploid in nature.

The prenatal development includes all the stages that are involved in the development of the single cell till the completion of the nine months of the fetus. The development of all organs and the process of the cell specification all occurs in the prenatal development stage.

Thus, the answer is prenatal.

Identify the model that best represents the plasma membrane of a hypothetical cell that exists in a nonaqueous environment and w

Klio2033 [76]

Answer:

The models are missing in the question. The models along with the question is provided in the attachment below.

The answer is : Model A represents the Plasma membrane.

Explanation:

According to the question, model A represents the plasma membrane. The reasons are :

(a). In the model A, the bilayers consists of two leaflets of the amphipathic lipid molecules. Here the polar head groups is in contact with the intra cellular or the extra cellular non aqueous phase, where the non polar tails are facing each other constituting the hydrophobic interior of the membrane.

(b). Lipid are not rigid as well as static structure. In the lipid bilayer, the lipid molecule are able to rotate around their axis freely and diffuse laterally with each leaflet.

(c). The plasma membrane acts as the selective plasma membrane.
