Answer:

1.Apoptosis in Cancer

The loss of apoptotic control allows cancer cells to survive longer and gives more time for the accumulation of mutations which can increase invasiveness during tumor progression, stimulate angiogenesis, deregulate cell proliferation and interfere with differentiation [2].

2.BCL-2 family proteins are the regulators of apoptosis, but also have other functions. This family of interacting partners includes inhibitors and inducers of cell death. Together they regulate and mediate the process by which mitochondria contribute to cell death known as the intrinsic apoptosis pathway.

Which statement best describes a scientific theory?

Liono4ka [1.6K]

The statement that describes a scientific theory is as follows: Jose explained that all planets orbit around the sun in an elliptical path (option A).

<h3>What is a scientific theory?</h3>

A scientific theory is a coherent statement or set of ideas that explains observed facts or phenomena and correctly predicts new facts or phenomena not previously observed.

A theory can also be described as a statement that sets out the laws and principles of something known or observed, in other words, a hypothesis confirmed by observation, experiment.

According to this question, the fact that all planets orbit around the sun in an elliptical path is a scientific theory because it has been tested and confirmed to be true.

Therefore, the statement that describes a scientific theory is as follows: Jose explained that all planets orbit around the sun in an elliptical path.

Normally, how many chromosomes are required to determine the outward expression of a trait?a homologous paironly oneany twotwo p

jeka94

Answer:

A homologous pair

Explanation:

In determining the expression trait of humans, this is based on the homologous chromosomes. This in turn comprised of alleles otherwise known as homologous alleles. The homologous loci are thereby located in these alleles which served as the formation of traits when combined.

Hence, normally, A HOMOLOGOUS PAIR is required to determine the outward expression of a trait?

The mechanism by which the end product of a metabolic pathway inhibits an earlier step in the pathway is most precisely describe

defon

Answer:

The mecanism is termed as feedback inhibition.

Explanation:

In an enzyme catalyzed sequential reaction the end product of that reaction inhibits the activity of the activity of the enzyme catalyzing the ist step This type of regulation is called Feed back regulation or feedback inhibition.

The main function of human body is to maintain the homeostasis of the all the components it contains.When the end product of an ongoing enzyme catalzsed sequential reaction is produced in a high lebel at that time to maintain its own homeostatis that end product inhibits the functioning of the enzyme catalzsing the ist step of that biochemical reaction.

For Example Cytidine tri phosphate inhibits the activity of aspartate transcarbamoylase catalyzing the de novo biosynthesis pathway of pyrimidine metabolism.
