Answer:
q1 : ribosomes because they are responsible for protein synthesis
q2 : by transporting potassium ions into the cell and sodium ions out of the cell maintaining a concentration gradient
q3 : seawater contains a high concentration of sodium and chlorine ions that the Atlantic cod gets rid of by actively transporting them out of its body
Answer:
Non- targeted cell lacks intracellular receptor for these hormone.
Explanation:
Receptors that are found on the cell surface are called cell surface receptor and those which are found inside the cell are called intracellular receptors. Intracellular receptor binds to lipophilic molecules. Each receptor binds specifically to a particular ligand or signal molecule.
So even though testosterone and estrogen can diffuse in every cell they will only affect those cell which have specific receptor which can bind to these hormones and then regulate the transcription of a specific gene in the nucleus.
So only those cells will respond to testosterone and estrogen who have specific intracellular receptors for them.
The green frog's population decreases because they cannot blend as easily into the mostly brown environment of the dry river bed as their brown counter parts. There are not as many green plants for them to hide against, making it easier for predators to see them.
A fold shaped like an elongate arch is an anticline.
<h3>What is an anticline?</h3>
An anticline occurs when the rock folds, this folding of the rock gives rise to an arch like shape.
The folding occurs in the strata layer of the rock to give an anticline.
Therefore, a fold shaped like an elongate arch is an anticline.
