Answer:
Primary succession occurs following an opening of a pristine habitat, for example, a lava flow, an area left from retreated glacier, or abandoned strip mine. In contrast, secondary succession is a response to a disturbance, for example, forest fire, tsunami, flood, or an abandoned field.In primary succession, newly exposed or newly formed rock is colonized by living things for the first time. In secondary succession, an area that was previously occupied by living things is disturbed, then re-colonized following the disturbance.
Explanation:
It is predation. How?
What do you think will happen if the fox catches the rabbit.
The fox will eat it.
Thus, predator-prey relationship; the fox gets full, and the bunny, well, it's not so good.
Answer:
As insect nymphs grow larger, their exoskeleton becomes too tight and they must replace it. Once a nymph outgrows its exoskeleton it will go through a process called molting, in which it leaves the old “skin” or exoskeleton behind. The new “skin” will harden and become the new exoskeleton
Explanation:
By predicting how the sodium-potassium pump becomes integrated into outer cell membrane. The prediction that is false is the mRNA coding into sodium pump is translated into the pump on two ribosomes.
<h3>What is sodium-potassium pump?</h3>
The sodium-potassium pump is an enzyme (an electrogenic transmembrane ATPase) present in the membrane of all animal cells. It is also known as sodium-potassium adenosine triphosphatase, Na+/K+-ATPase, or sodium-potassium ATPase. It serves a number of purposes in cell physiology.
The enzyme Na+/K+-ATPase is activated (i.e. it uses energy from ATP). Three sodium ions are exported and two potassium ions are imported for each ATP molecule used by the pump. As a result, each pump cycle results in the net export of one positive charge.
There are four distinct sodium pump isoforms or subtypes in mammals. Each has distinct qualities and patterns of tissue expression. The P-type ATPase family includes this enzyme.
