Answer:
Littoral Communities
Littoral areas of ponds and lakes are typically better oxygenated, structurally more complex, and afford more abundant and diverse food resources than do profundal sediments. All these factors lead to a high diversity of insects and very complex trophic interactions (see Section IV.

Answer:
<h3>Velocity (Rate of change of position)</h3><h3>Velocity is a vector quantity that is defined as the rate of change of position of an object with respect to a frame of reference with respect to time. Velocity is equivalent to the speed of the object along with the direction of motion.</h3><h3>Hope this is fine for you</h3>
The percentage of progenies with red eyes and spine will be 56.25%.
<h3><u>Explanation:</u></h3>
This cross will be just similar to Mendel’s Dihybrid cross where he crossed the pea plants considering two characters at once.
Here two characters that are taken into account are eye colour and presence of spine. The eye colour has two traits - red and brown. Red colour is dominant. The presence of spine has also two possibilities - presence of spine or absence of spine.
The allele denoting red eye colour is R and allele denoting brown eye colour is r. Similarly, the allele denoting presence of spine is S and absence of spine is s.
Genotype of the heterozygous parents = RrSs.
Gametes produced by the parents= RS, Rs, rS and rs.
So crossing them, we get the phenotypic ratio of red eyed spined : red eyed spineless : brown eyed spined : brown eyed spineless = 9:3:3:1.
So, the percentage of red eyed spined = 56.25%.
