The cells with the small size have the surface area and volume that are proportional to each other such that this aids with the efficiency of the cell's absorption of nutrients and defecation process of the wastes. Hence, the small dimensions of cells is more efficient than the large ones.
In the absence of tryptophan, the genes trpA-E will not be transcribed.
If there were a mutation in the operator region of the trp operon, there would be a nucleotide change in the sequence of the operator. Mutations in the repressor that prevent its binding to the operator will lead to constitutive expression Mutations that prevent binding of the inducer without affecting the ability to bind to the operator lead to a non‑inducible phenotype.
The tryptophan binds to the trp repressor and causes it to change shape, converting into its active form. The trp repressor with the bound tryptophan attaches to the operator, blocking RNA polymerase from binding to the promoter and preventing transcription of the operon.

Answer:
The true statement will be - D
It is a involvement of groups of transcriptional regulators which work together to determine the expression of a gene.
Explanation:
Combinatorial gene regulation is a mechanism by which small numbers or groups of transcriptional factors or regulators can control the expression of a much larger gene with temporal and spatial patterns.
The process by which a cell regulates the conversion of DNA to RNA to increase gene activity is known as Transcriptional regulation. A single gene can be regulated by altering the RNA which is transcribed.
The gene control allows the cell to respond to a variety of intracellular and extracellular signals.
The observable cellular process of the physical basis of Mendel's law comes from the first division of meiosis,This is further explained below,
To find the "What observable cellular process explains Mendel’s law of segregation?" we need to know more about Mendel’s law of segregation?
<h3>What observable cellular process explains Mendel’s law of segregation?</h3>
According to Mendel's Law of Segregation, a diploid organism passes a randomly selected allele for a trait to its offspring, with each parent receiving one allele.
In conclusion, The first division of meiosis , is the physical basis of Mendel's law of segregation.

Answer:
The chemical equation for photosynthesis is 6CO2+6H2O→6co2+6h2o. In plants, the process of photosynthesis takes place in the mesophyll of the leaves, inside the chloroplasts. Chloroplasts contain disc-shaped structures called thylakoids, which contain the pigment chlorophyll.
