Answer:
Large quantities of water molecules constantly move across cell membranes by simple diffusion, often facilitated by movement through membrane proteins, including aquaporins. In general, net movement of water into or out of cells is negligible. For example, it has been estimated that an amount of water equivalent to roughly 100 times the volume of the cell diffuses across the red blood cell membrane every second; the cell doesn't lose or gain water because equal amounts go in and out. There are, however, many cases in which net flow of water occurs across cell membranes and sheets of cells. An example of great importance to you is the secretion of and absorption of water in your small intestine. In such situations, water still moves across membranes by simple diffusion, but the process is important enough to warrant a distinct name - osmosis.
Answer: The estimated size of the population is 150
Explanation: For the Mark-Recapture method, there is a formula that can be used:
N = (M × C)/R
where :
N = estimated number of individuals in the population
M = number of individuals captured and arked
C = total number captured the second time (with and without a mark)
R= number of individuals ecaptured (those with a mark)
So with this formula we can calculate an estimation of the population of rodents. Because there is no number of rodents captured the second time given, we will assume 30 was caught again, making the 20% found marked being 6. We calculate it as:
N = (M × C)/R
:N = ( 30 × 30)/ 6
:N = 900/6
:N = 150 estimated rodents in the population
Answer:
A function that does not correspond to proteins is energy.
Explanation:
Proteins are macromolecules, considered essential nutrients, which participate in the mechanisms of construction, development and repair of the body, among other functions.
The energetic function is not a fundamental function of proteins, although they can be considered an alternative source of energetic substrate. The main source of energy of the organism is constituted by the carbohydrates.
The other options certainly describe functions of proteins:
- <u><em>Build and repair
.</em></u><em> Proteins are the main components of muscles and connective tissue.</em>
- <u><em>Transport molecules</em></u><em>. Globulins are a type of proteins in charge of transporting essential substances, such as transferrin, an iron-carrying globulin.
</em>
- <u><em>Regulation of body process</em></u><em>. Enzymes are formed by proteins and intervene in innumerable biochemical processes in the organism, as bio-catalysts.</em>
