An example dandilions have adapted to have a unbrella like structure allowing it to float long distances away from the parent plant so it won't have to compete with resrouces
Passive transport has 3 concepts to it.. these include: diffusion, facilitated diffusion and osmosis. All 3 of these are when a solution goes from an area of high concentration to an area of low concentration. All three of these are how substances move in and out of cells. Active transport refers to a substance going from an area of low concentration to an area of high concentration. The three of these include: plasma membrane in relation to calcium and potassium, endocytosis, and extocytosis. The function of these three is to also bring substances from an area of high concentration to an area of low concentration. Membrane pumps do this by bringing the high concentration to inside the cell so the potassium and calcium switch spots. With endocytosis and extocytosis, endocytosis brings items into the cell by digesting (phagocytosis) and drinking them (pinocytosis); extocytosis almost pushes away the cell and that’s how it gets across the membrane
The major muscles involved while performing a wall sit or squat are the quadriceps muscles.
Explanation:
Exercises like wall sit or squat are an isometric exercises which works the entire group of lower body muscles.
Isometric exercises are endurance building exercises which improves the muscle endurance by holding it in a position for longer time. These exercises does not involve any big bodily movements but works by tensing the muscles.
Both these exercises primarily involve the front thigh muscles or the quadriceps. Squats and wall sits help to tone and shape the quads and other muscles involved. The angle of the body should be maintained at right angle to reduce the pressure on these muscles.
Other muscles which are involved in these exercises are the hamstrings, core, lower back muscles etc.
It prevents dust from settling on the scope and in the lenses. Also, if working in a lab, a cover can prevent contamination.
