Unequal reproductive success ______.Group of answer choicescan lead to a population being less well adapted to its environmentca
postnew [5]

Answer:

can lead to natural selection

Explanation:

<h2></h2><h2>Unequal reproductive success<em> _can lead to natural selection_____.</em></h2>

This is because if there is unequal reproductive success then one of the organisms is <em>better suited for reproducing, surviving, and passing down their genes to their offspring</em> rather than the organism who is unfit. This is where natural selection comes into play because natural selection is process where <em>i</em><u><em>ndividuals better suited for their environment produce more and have better survivality. </em></u>

So overtime, the organism which is weaker  (in sense of fitness) (here fitness relates to reproduction and survival), will not pass as many genes and won't survive, whereas, individual better suited will, hence in  a way "<u>Nature selected"</u><u> </u>the better fit organism.

Receipt of extracellular signals can change cell behavior quickly (e.g., in seconds or less) or much more slowly (e.g., in hours
balandron [24]

Answer:

A. Molecular changes such as extracellular signals on extracellular ligands can result in quick changes in cell behaviour. One example is insulin. Upon insulin binding on the receptor on the cell membrane, the cell release GLUT4 transporters (for muscle cells) to increase uptake of glucose.

B. Slow changes in cell behaviour can be observed for other lipophilic hormones or intracellular receptors such as glucocoortoid or estrogen which reacts with receptors in the cells.

C. Insulin is required to maintain a constant blood glucose level and hence levels of insulin has to be mediated in correspondence to the blood glucose levels. Fast acting signalling is thus required for homeostasis of blood glucose levels. Where for such lipophilic hormones such as steriods, glucocortoid, these hormones tend to have a longer lasting effect and hence results in a slow change.

miRNAs can control gene expression by what action?A. degrading proteins as soon as they are formedB. inhibiting the catalytic ac
levacccp [35]

Answer:

C) binding to mRNAs and degrading them or blocking their translation

Explanation:

<u>miRNAs:</u>

miRNAs is the abbreviation of MicroRNAs. These are the small noncoding RNAs of ∼22 nucleotides which can not code for peptides. miRNAs are responsible for gene expression regulation at the level of post transcription. They can do so by forming complementary base pairing with target mRNA and inhibiting their translation.

They silenced mRNA by the following processes:

(1) Cleavage of the mRNA strand into pieces,

(2) stopping mRNA from translation into proteins by ribosomes.

(3) Shortening of mRNA poly(A) tail and destabilizing it.
