Answer:
Explanation:
Water will not move in as the movement of water molecules will be the same in both directions. There will be no net movement of water molecules.
Hope this helps
the answer would be D. Presence of cell membranes.
Pioneer species are the first species that colonize places where there were previously no other living organisms, such as algae that colonize bare rocks. ... Therefore, they pave the way for other species to establish themselves at the location through the creation of new potential ecological<span> niches.</span>
It is mostly likely the cell membrane.
The cell membrane is a structure of a cell composed of double layer of lipids and proteins. It surrounds a cell and separates the cytoplasm from its surrounding environment. The cell membrane is selectively permeable (semi-permeable), which means that it only lets certain molecules enter and exit. It can also control the amount of some substances that go into or out of the cell.
The number of chromosomes does not correlate with the apparent complexity of an animal or a plant:
in humans, for example, the diploid number is 2n = 46 (that is, 23 pairs), compared with 2n = 78, or 39 pairs, in the dog and 2n = 36 (18) in the common earthworm.
