A similarity would be that they are both muscles. A difference would be cardiac muscle is only in the heart while skeletal muscle can be found throughout the body. Another similarity would be that they are both striated. Another difference would be that skeletal muscle is generally on conscious or voluntary control while the cardiac muscle is automatically used to keep your heart pumping
Analogous structures have a different evolutionary ancestries but they have the same function
while homologous structures are the opposite; they have similar ancestries and common traits but maybe not have the same function in an organism
Answer:
It means that the cell membrane allows certain substances to pass through and not others. As the cell membrane consists of a phospholipid bilayer with a hydrophobic core, only small uncharged hydrophobic molecules can pass through the cell membrane e.g. glucocorticoid and other larger charged particles require transporters or channel proteins to pass through the cell membrane, e.g. glucose.
Answer & Explanation:
Feedback is a form of regulation where the main product of one reaction, can also inhibit it. It can work in several ways, mainly there's a receptor that, somehow, measures the presence of a determined molecule, in this case, ATP. These receptors can also be involved in the metabolic process and when there's an excess of ATP, the enzymes are inhibited, maybe with an allosteric type of inhibition.
