It depends on the statement, but most aren't true from my perspective. Perspective also determines the validity of the statement.
Hope this helps and please give brainliest!
The answer is A as corals are very delicate to their surroundings
The parallel evolution of flowering plants and pollinators represents a case of coevolution. It may lead to different types of natural selection.
<h3>Disruptive, stabilizing, and directional selection</h3>
Disruptive selection is a type of natural selection that favors extreme phenotypes (in this case, flowers too small or too big).
Stabilizing selection is a type of selection that leads to decreased genetic variation (in this case, all red flowers to attract pollinators)
Finally, directional selection is a type of natural selection where an extreme phenotype can be favored (in this case, taller plants to be noted by bees).

<span>Adult's urine generally has a specific gravity in the range of 1.000 to 1.030.
Increases in specific gravity of urine are said to be hypersthenuria. For example, increased the concentration of solute in the urine. While decreases in specific gravity of urine concentration result in hyposthenuria.
The concentration of solute levels may be slightly lower after drinking an unusually high amount of water, this occurs only because the urine has been diluted and concentration of solutes is less.
The lower protein level doesn't mean there are fewer solutes because it simply there is more water. Drinking an excessive amount of water is immediately apparent reason being urinalysis test which includes an indication for a specific gravity.
Specific gravity is referred to as the ratio which compares the density of urine compared to the density of water. If you drink a lot of water the specific gravity of urine is lower than normal.</span>
