Answer:
The cell membranes controls what goes in and out by having protein channels that perform their role accordingly sometimes like funnels and like a pump in different cases.
When a channel open in the plasma membrane it allows molecule to pass through, in this case there is no requirement for energy so it is a passive transport.
Gases and food particles broke down in water must be assimilated and waste or harmful substance and molecules must be remove. For most cells, this type of selective transport of all materials all through the cell must happen through the plasma membrane.
Answer: A.
Explanation:
There core, or inner layer, is the most dense due to its magnetic pole, not to mention, the core is comprised of multiple molten materials, heated so hot, tht it practically exist between two states of matter simultaneously.
The examples of positive feedback loops are as follows:
- contractions during the process of giving birth
- Blood clotting
<h3>WHAT IS POSITIVE FEEDBACK LOOP:</h3>
- Positive feedback loop is that in which a change in a given direction causes additional change in that same direction.
- The contractions during the process of giving birth is an example of positive feedback loop because the contractions further stretch the walls and continues until birthing occurs.
- Also, the clotting of blood causes the stoppage of blood flow.
Therefore, the examples of positive feedback loops are as follows:
- contractions during the process of giving birth
- Blood clotting

Explanation:
when an animal in an ecosystem consisting of such things as what it eats, when it eats, and where it lives would be called a <u><em>NICHE</em></u>.
Answer:
Restoring force is a force which acts to bring a body to its equilibrium position. The restoring force is a function only of position of the mass or particle, and it is always directed back toward the equilibrium position. Therefore the restoring force of air particles should be displaced in the direction of the force and according to Newton 3rd law of motion, once the force is removed, restoring force of elasticity returns the displaced particle to a resting state .
