Crossing over is important because it creates genetic variability.

<h3>What is crossing over?</h3>

It is the exchange of chromosomal segments between non-homologous chromosomes in a tetrad.

Since chromosomal segments contain genes at different loci, the exchange will increase the genetic variability of the new chromosomes.

Thus, the daughter cells carrying the recombined chromosomes will be genetically variable from not just the parent cell, but fellow daughter cells.

Katyanochek1 [597]

Answer:

The correct answer is option C. "2+".

Explanation:

A common procedure to test for the presence of antigens is to perform an agglutination reaction by performing an antibody screen. In an agglutination reaction that is graded  2+ the red blood cells start to be broken and medium-sized agglutinates are formed. In this reaction no red blood cells are free, only agglutinates are seen at the bottom of the microtubes. The characteristics of the reaction herein described concur with an agglutination reaction that is graded  2+.

Jobisdone [24]

Answer:

Grunion (Leuresthes tenuis): life begins at high tide. During summer and spring, thousands of these fish swim up onto sandy beaches (carried in by high tide). This is called a grunion run, and it occurs ta night during the new moon and full moon when the tide is highest. The females wiggle into the sand and lay thousands of eggs as the males deposit sperm around them. Afterward, they are swept back into the sea. The spawning is timed so exactly that it occurs only on the second, third, and fourth days that follow a new or full moon. After the grunion eggs are fertilized, they incubate for two weeks until the next new or full moon occurs.

Horseshoe Crab (Limulus polyphemus): during late May and early June, vast numbers of horseshoe crabs come together in shallow bays, marshes, and inlets along the Atlantic and Gulf coasts, waiting to come up on the beaches to spawn. The signal to begin is provided by the moon. During the new and full moons, when tide is highest, the crabs come ashore. The female produces a cluster of tiny eggs on her abdomen, and the eggs are fertilized by the male's sperm, and then deposited out in the sand by the female. The next two weeks, the eggs incubate until they hatch during the next full or new moon. When the high water reaches the eggs, they hatch and go out into the ocean.

The Coriolis effect happen when ?
Pie
The Coriolis effect<span> is caused by a combination of the inertia of moving air and the rotation of the Earth. Air tends to move from high pressure to low pressure in a straight line, but the rotation of the Earth means that, to an observer at one spot on its surface, the moving air appears to turn.
