Answer:
Explanation: How do things move across a cell membrane?
Summary. Controlling the movement of things in and out of the cell is an important role of the plasma membrane. ... Osmosis is the diffusion of water molecules across a membrane. Water moves in or out of a cell by osmosis until its concentration is the same on both sides of the plasma membrane.
<u>Nitrogen and potasium levels</u> are NOT primary measures of soil quality.
Explanation:
The deeper the soil horizon, the more fertile the soil. This is because this means the soil has had enough time to weather and release the elements/minerals held up in the parent rock.
Soil composition is also important for soil quality. The good ratio silt, clay, and sand can determine the quality of the soil. This same composition can determine the holding capacity of water in the soil for plants and other soil organisms.
Organic matter is important in raising soil quality. They ensure the soil retains water nutrients from leaching

Answer:
It's fibers
Explanation:
Its fibers are longer than they are wide, and they are striated, like skeletal muscle fibers. But, unlike skeletal muscle fibers, cardiac muscle fibers have distinct ends to them, called intercalated discs.
Answer:
The cell membrane
Explanation:
The arrow is pointing to the outside ¨shell¨ so to speak which is the cell membrane, bacteria do not have cell membranes
Answer:
Negative feedback.
Explanation:
The normal carbon dioxide levels after resting, the breathing rate also decreases which is an example of negative feedback because the body moves towards stability or equilibrium conditions. There is a direct relationship between breathing rate and carbondioxide levels means if one is increases the other automatically increases in order to maintain homeostasis in the body so we can say that this relationship is very important to maintain .stability in the body
