<span>The correct answer is b. The open ocean. The definition of an island ecosystem does not have anything to do with water, but simply refers to an ecosystem that exists as a microcosm within a far larger, separate ecosystem. The ocean has lots of separate island ecosystems within it, but it itself cannot be referred to as one.</span>
The right answer is chromosome > DNA > gene.
Living cell element, of characteristic shape and in constant number, located in the nucleus of the cell.
DNA, which is our chromosome, carries the genes
. The DNA molecule, also known as deoxyribonucleic acid, is found in all our cells.
The gene is a piece of this DNA that corresponds to a particular genetic information that codes for a single protein. So it's a very small portion of chromosome.
Vacuole is the answer.
Wilting is the loss of rigidity of non woody parts of plants and occurs when turgor pressure falls.
The vacuole controls turgor pressure. Turgor pressure dictates the rigidity of the cell and is associated with the difference between the osmotic pressure inside and outside the cell.
When a plant receives adequate amounts of water, the central vacuoles of its cells swell as the liquid collects within them creating a high level of turgor pressure which helps maintain the structural integrity of the plant along with the support of the cell wall.
In the absence of enough water , central vacuoles shrink and turgor pressure is reduced compromising the plant's rigidity so that wilting takes place.
Radiation can actually affect the entire body, however it has a large effect of the bone marrow. Radiation is dangerous because too much can cause cellular depredation, this happens in environment that rapidly change like the bone marrow, which then interferes with blood cell production.
Answer is A because the habitat’s resources are depleting
