Answer:
A major reason for the lack of any substitution effect with aquaculture, says Longo, is that many farmed species, such as salmon and bluefin tuna, are top predators so farming them requires feed made from other fish. ... “But it's hard to take a top marine predator and feed it soy meal,” Wiber says.
Explanation:
The repressor protein is coded by the i gene.
<h3>What is the function of the repressor protein in lac operon?</h3>
A protein known as a repressor prevents one or more genes from being expressed. The i gene codes for the repressor protein. The repressor protein inhibits messenger RNA synthesis by attaching to the promoter region of the gene(s). For the control of gene expression in cells, repressor proteins are crucial.
Repressors and activators of gene expression in bacteria are different from one another. However, depending on how a DNA binding protein interacts with other proteins in the cell or in other biological contexts, higher eukaryotic cells can use it as either an activator or a repressor of gene expression. As repressors, additional components like non-coding RNA may also be present.

Explanation:
Epinephrine triggers a direct signal transduction pathway.
I know this because when epinephrine binds to it's receptor example on a muscle cell,this is known as a type of G protein -coupled receptor,signal transduction cascade is triggered and this involves the production of a second messenger molecule cyclic AMP(cAMP).
Epinephrine also know as Adrenaline or sus-phrine.
It is a vasoconstrictor,broncho dilator and a sympathetic stimulant.
It constricts the peripheral abdominal organs as well as a stimulating the heart beat thereby raising the blood pressure,it also relaxes the spasms of the bronchial muscles thereby promoting ventilation of the lungs.
