Firstly, start by doing Punnett squares for each of the characteristics. Attached are the three Punnet squares, made by me, as they should look in end.
For each of the Punnet squares, one characteristic each, we find that half of the offspring will be heterozygous for that characteristic.
Therefore, according to the product rule, you should now multiply the quantity of heterozygous for each characteristic and then obtain the total part of the offspring that's fully heterozygous.
Ss×
Ll×
Rr=
SsLlRr
Total offspring×
=10
There is 10 plants in the total offspring that are heterozygous for all the considered three genes.
As a mechanism of evolution, natural selection can be most closely equated with UNEQUAL REPRODUCTIVE SUCCESS.
Mechanism of evolution refers to micro-evolution that involves mutation, gene flow and natural selection. Unequal reproductive success is also related to other processes of micro evolution such as natural selection. The organisms that can reproduce unequally and survive even in adverse condition, increase in numbers.

Answer:
of diffusion
Explanation:
Molecules move down a concentration gradient without the need to use energy. This means they move from a high concentration to a low concentration. This occurs across a semi-permeable membrane, like the cell membrane, by simple diffusion.
Answer:
A)Biomass is transferred from one organism to another when one organism consumes another organism. When a predator organism eats the prey organism, the molecules on the food are broken down by the digestive system into smaller molecules. These smaller molecules like lipids, amino acids, glucose are used by the organism for various purposes.
B) Energy that is not transferred from one organism to another is either used up by the organism for various purposes. Most of the energy is lost into the environment in the form of heat.
c) There are typically fewer organisms at the top of the trophic levels because energy keeps on declining at each trophic levels so the number of consumers which it can satisfy also decreases.
d) Only 10% of the energy passes from one trophic level to another. The rest is usually lost in the form of heat. For example, if there was 100% energy in the producers, only 10% would pass to the primary consumers. The secondary consumers will receive 1%.
