Answer:

The answer is C.

Explanation:

When you breathe out or exhale, your diaphragm relaxes and moves up into your chest cavity. As the space in your chest cavity gets smaller, the air rich in carbon dioxide is forced out of your lungs and windpipe, and then out your nose or mouth.

lapo4ka [179]

Options are not given in the question. The complete question is as following:

Gene expression is often assayed by measuring the level of mRNA produced from a gene. If one is interested in knowing the amount of a final active gene product, a potential problem of this method is that it ignores the possibility of _____.

A) chromatin condensation control

B) transcriptional control

C) alternative splicing

D) translational control

Answer:

D) translational control

Explanation:

Gene expression is the mechanism used in the production of a functional gene product through information from a gene. This results in much more rapid cellular change by direct protein concentration regulation.

Translational regulation refers to regulating the protein concentrations synthesised from its mRNA. This control is of great importance for the cellular response to stressors, signs of growth and differentiation. This results in much more rapid cellular change by direct protein concentration regulation.

Hence, to evaluate gene expression it is important to measure the possibility of translational regulation as most of the time, function of the stop codon is ignored by ribososme which leads to long peptide chains and interfer with gene expression.

So, the correct answer is D).

A strawberry plant is an example of a plant that can reproduce through the process of vegetative reproduction. Are the offspring
alexandr402 [8]
The offspring will be genetically identical to the parent because vegetative reproduction is a form of asexual reproduction. Therefore, there is only one parent and the offspring is identical to the parent.

Electrons spin in shells around the nucleus. The closest shell (n = 1) can contain a maximum of _____ electrons?
LUCKY_DIMON [66]

The given blank can be filled with two electrons.  

The K, L, M, N are the four shells in an atom. The K shell is the initial that is present nearest to the nucleus of the atom, and it comprises two electrons. The L shell can withstand eight electrons, M shell can withstand eighteen electrons, and however, the atom attains stability if the last (valence) shell comprises eight electrons.
