Epithelial cells with important transport functions such as absorption and secretion often bear on their free surfaces.

microvilli

Explanation:

Microvilli are projections, extensions of the plasma membrane, found in epithelial cells and absorption cells, such as intestinal cells that aid in nutrient absorption. In other words microvilli are folds in the plasma membrane at the surface of the intestinal cells that increase the contact surface and thereby increase nutrient absorption.

Many researchers have observed that epithelial cells with important transport functions, such as absorption and secretion, often carry microvilli on their free surfaces.

correct answer: biotic and abiotic limitations

carrying capacity is defined as the total number of an organism who can be supported in a given area within the natural resources limit and without harming or degrading the natural, economic or the cultural environment present for the future generations.

carrying capacity is determined by the limiting factors, which are known to affect the natural resources available. it may include water, nutrients, minerals, space, light etc.

explanation:

hope this ! have a wonderful day!

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.
