Answer:
Energy and Cellular Space
When gene Gene expression at( transnational level ) is regulated it ensures <u>energy and cellular space conservation</u>, If a gene were to be regulated at each time after transcription, then significant amount of ATPs beyond the synthetic capacity of the cells will be needed, the cells will need large surface to accommodate the mechanism s. Thus regulation saves more energy and space to regulate gene expression. by turning on genes when needed to expressed and off when not needed.
Sequence of Gene
In addition, for the timely synthesis of exact copies of protein needed by the cells for various cellular activities; it is important for cells to regulate and control how the DNA is translated to the required proteins. If this mechanisms were not regulated deletion , addition of nitrogenous bases in gene sequence during translation may lead to mutations and therefore wrong coding of the needed protein in the cells.
Protein Quantity
Furthermore, the need to know the quantity of protein to synthesize, when to stop the synthesis, necessitated regulation of the process.If required amount is not expressed wrong amino acids units will be synthesized leading to abnormalities in hormones and enzymes.
Explanation:
The answer is <span>Time is the independent variable, and the number of birds is the dependent variable. </span>
<span>An independent variable is variable that is not affected in the experiment. It is what experimenter controls. On the other side, a dependent variable is called dependent because it depends on the independent variables. It is what is affected during the experiment.
In Sam investigation, he controls time - he counts birds at 6 a.m. and 6 p.m. So, time is the independent variable. The number of birds is affected during the experiment, so it must be the dependent variable.

The photo is showing human karyotype. Haploid=n, diploid=2n. The picture shown 23 pair of chromosome which mean n=23. Therefore, diploid number of this individual is 46.
As the cube size increases<span> or the cell gets bigger , then the </span>surface area to volume ratio<span> - SA:V </span>ratio<span> decreases. When an </span>object<span>/cell is very small, it has a large </span>surface area to volume ratio<span>, while a large </span>object<span>/ cell has a small </span>surface area to volume ratio<span>.</span>
