Back in Darwin’s time, people thought that animals sources were a nonhuman ancestors.

c, d, a, b, f, g, e
The impulse starts at the SA node that has its own contraction rhythm (but can be faster or slower depending on other impulses or hormones). That impulse travels then through the atria and is slowed down by the atrioventricular septum except for a region in the right atrium called AV node where the impulse has continuity. The impulse travels then to the ventricles through the AV bundle. The impulse continues through bundle branches to other fibers: Purkinje fibers. These Purkinje fibers cause then a contraction that goes from the apex of the heart and rapidly through the ventricles.</span>
Answer:
the trait with Mendelian inheritance shows segregation in the F2 generation.
Explanation:
Blending inheritance is the theory that the offspring inherits any characteristic that are intermediate between those of the parents.
However, Gregor Johann Mendel showed that this not true that hereditary substances from parents merge together in their offspring.
In the given question,
the offspring of true-breeding parents show an intermediate phenotype, although a trait such as flower color in snapdragons is determined by two alleles with incomplete dominance.
The difference is that the trait with Mendelian inheritance shows segregation in the F2 generation.
The correct answer is - nutrients.
The cold water is very rich in nutrients, and those nutrients are crucial for the survival of the small organisms as they are their primary food source. When El Nino occurs though, the water is becoming warmer and stops the up-welling of the cold water, which also means that the nutrients remain deep with it. As a result, the small organisms are left without their primary food sources, thus they struggle to survive, and even die out in the region on a large scale.
