Answer:
0
Explanation:
This question involves two genes; A and B. According to the question, two parents are crossed as follows: AABB × Aabb. The parents will produce the following gametes:
AABB- AB, AB, AB, AB
Aabb - Ab, Ab, ab, ab
Using these gametes in a punnet square (see attached image), the offsprings in the following proportion will be produced:
AABb = 4/16 = 1/4
AaBb = 4/16 = 1/4
Therefore, none (0) of the offsprings will resemble the phenotype of the second parent (Aabb).

Explanation:
In open systems, hemolymph is not contained in vessels and instead surrounds tissues and organs. In an earthworm's circulatory system, blood is contained within vessels (dorsal, ventral, and lateral), which categorizes it as a closed system.
All organisms need energy to survive. It requires many units of lower trophic level organisms to feed the next trophic level. For example many first order consumers (fish) are required to feed one crocodile (top order consumer). This is because energy is lost as heat at each trophic level, so the energy available to the top feeding level is far lower than that of the producers (plants). This is what restricts the number of trophic levels in a food chain to four or five.
