Answer:

There should be more groups of subjects, each consuming a different quantity of beta carotene.

Explanation:

For them to determine whether the amount Vitamin A absorbed by the body is dependent on the amount of beta carotene consumed, what they need to do is to create more groups each consuming a different amount beta carotene by so doing, they have been able to modify the experiment to determine whether the amount of vitamin A absorbed by the body is dependent on the amount of beta carotene consumed.

Answer:

The experiment should have more different subject groups, with each group consuming a different amount of beta carotene.

Explanation:

When designing an experiment, to determine the effect of the amount of a substance, the experimental design should be done to accommodate more than two experimental group with each group treated with different amount of the substance and also a control group. This will enable the researcher to determine the effect of the different ranges of amount.

In the example, in other to determine if vitamin A is dependent of the amount of beta carotene consumed, there should be more different subject groups, with each group consuming a different amount of beta carotene.

Can mRNA coding for a protein destined to be embedded in the plasma membrane associate with rough ER prior to the initiation of
Debora [2.8K]

Answer:

mRNA must start membrane protein in the cytoplasm and, after that, continue it in the rough ER.

Explanation:

Protein synthesis is initiated when mRNA meets a free ribosome, the primary structure for protein synthesis. Ribosomes can be found in the r<em>ough endoplasmic reticulum</em> or floating in the cytosol. They read the mRNA code and add the correct amino acid using transference RNA to build the protein.

The <u>rough endoplasmic reticulum</u> is in charge of the synthesis and transport of the membrane proteins. It is also in charge of the latest protein modifications after transduction. Synthesis of membrane proteins <u>starts in the cytoplasm</u> with the production of a molecule portion known as a signal sequence. This portion leads the synthesizing protein and associated ribosome to a specific region in the Rough endoplasmic reticulum where it continues the protein building.

Membrane proteins are synthesized in the endoplasmic reticulum and <em>sent to the Golgi complex in vesicles</em>, where it happens the final association of carbohydrates with proteins. Finally, protein is transported <em>from the Golgi complex to its final destiny, the membrane. </em>
