Answer:

The correct answer would be "Through a receptor on the cell membrane that transduces its signal to the cell's DNA".

Hormones produce their effects mainly by binding to their specific receptors. It leads to the formation of a hormone-receptor complex which results in certain biochemical changes on a target tissue.

These receptors can be of two types of membrane-bound and intracellular receptors.

The hormones which are protein or amine in nature are water soluble and thus can not pass through the lipid bilayer of a cell. They produce their effects mainly by binding to the membrane bound receptors. For example, insulin, growth hormone, Adrenaline, ADH, oxytocin, FSH, TSH et cetera.

Insulin binds to glycoprotein complex receptor present in the cell membrane.

In contrast, a lipid-soluble hormone such as steroidal hormone (estrogen) binds to the intra-cellular receptors as they can easily pass through the lipid bilayer.

Sati [7]

Answer:

Option A is the correct answer. To conduct a controlled experiment would be the best choice for Maria to test her prediction.

Explanation:

A controlled experiment can be described as an test in which one of the test models is kept constant for a variable, while in other experimental models, a change is made for testing the variable.

It would be best for Maria to conduct a controlled experiment. In the control model, Maria should keep light as constant whereas in other experimental models she should increase and decrease the quality of light to test her prediction. She should then compare her experimental results with the control model to deduce the results.

Liono4ka [1.6K]
Since the liver is the primary organ for metabolism, then in the setting of liver injury there will be reduced metabolism of compounds such as hormones. If these hormones are not metabolized and degraded in the liver, then these hormone levels will increase.

<em>A particular example is that the hormone estrogen is increased in the setting of liver damage, causing males with liver failure to have feminine characteristics.</em>
