Answer:

C) there would be a decline in the populations of primary producers

Explanation:

If a new primary consumer were introduced to the ecosystem, there will be more consumers with the same population of primary producers, wich means that it would be a decline in this populations. There would be more species that consumes, that species that produces.

The existence of introns in mRNA-encoding genes seems to be a problem because so much cellular energy goes into splicing them ou

Svetllana [295]

Answer:

In normal conditions, introns serve following functions in the body of an organism:

1) They contain genes of miRNA which are known as Mirtrons, reverse transcriptase, endonucleases, transposase etc.

2) It is because of presence of introns that alternative splicing of mRNA is possible. The sex determination in drosophila is based on alternative splicing.

Apart from this, alternative splicing can be useful and beneficial in an unforeseen situation such as an environmental problem which is faced by the organism for the first time.

Explanation:

Alternative splicing is an important mechanism because with the help of alternative splicing different type of proteins can be synthesized from the same pre mRNA transcript. In case suddenly the surrounding environment of an organism is changed and the environmental conditions have become extremely harsh due to which organism's life is at stake, in such situation organism may make a different type of protein through alternative splicing which can help the organism in survival.

Default splicing in Drosophila leads to the development of male off-spring while female off-spring is produced as a result of alternative splicing.

Anuta_ua [19.1K]

Her hypothalamus will secrete vasopressin. If her dehydration becomes severe, her secretion of vasopressin will increase.

<h3>What is vasopressin?</h3>

The posterior pituitary gland releases the peptide hormone vasopressin, also known as antidiuretic hormone.
Which is produced by the supraoptic and paraventricular nuclei of the hypothalamus (neurohypophysis).

It primarily functions as an anti-diuretic in the kidney, where it causes the body to reabsorb water by acting on the distal region of the nephron when it is dehydrated.
The AVP gene for it is found on human chromosome 20.
Vasopressin has an antidiuretic effect; it reduces the volume of urine by raising the collecting tube's water permeability.
It attaches to the G protein-coupled V2 receptor, which in turn starts a signaling cascade through the PKA.
Aquaporin 2 (a transmembrane pore) is produced as a result, and it is then transported to the apical/urinary membrane.
