Answer:  yes it most of the time is

Explanation:

The most commonly occurring mutation in people with cystic fibrosis is a deletion of a single codon. This results in:__________
ad-work [718]

Answer:

d) a polypeptide missing an amino acid.

Explanation:

Deletion is a type of mutation when one or more codons from the reading frame are removed. This results in the production of a relatively shorter mRNA that lacks one or more codons otherwise present in the non-mutated mRNA. When there is a deletion of a single codon in the gene for cystic fibrosis, the resultant shorter mRNA codes for a polypeptide chain that does not carry one amino acid. For example, deletion of one codon results in deletion of a Phe  residue present at position 508 in CFTR. The mutated transmembrane protein CFTR folds in an improper way.

evidence supporting paracrine hypothesis for akt-modified mesench- ymal stem cell-mediated cardiac protection and functional imp
Rudiy27

By injecting Mesenchymal Stem Cells with ability to express high amount of Akt or protein kinase B in myocardium, researchers witnessed restored cardiac function and inhibition of ventricular remodeling. The effect was seen after two weeks of administration of cells. The culture containing hypoxic Akt-MSCs (conditioned medium) inhibits apoptosis or cell death induced due to hypoxia. Also, it triggers in vitro contraction of cardiomyocytes, the cardiac cells specifically responsible for contraction function.

The desired functional improvement can occur in short time which is less than 72 hours, the reason for which was hypothesized as paracrine action of cells.  Hypothesis was proved by upregulation of genes that code for factors responsible for above mentioned effects (apoptosis and contraction). The factors are FGF-2, VEGF, HGF etc.

Why is the interdependence of the worms and plants an example of commensalism?
maks197457 [2]

Answer:

The interdependence of the worms and plants is an example of commensalism in a sense that as the worms burrow into the soil, it allows the soil to be<em> loosened</em> which then allows it to properly absorb water and carbon dioxide into its roots. This action <u>benefits the plants' growth.</u> However, such action of the worms,<em> neither benefit the worms nor does it cause any harm.</em>

Explanation:

"Commensalism" is a relationship between two things wherein <em>one benefits while the other is neutral</em>. This means<u> the other one doesn't benefit nor is it harmed.</u>
