Answer:

All plants of purple colour.

Explanation:

All the offspring plants of F1 generation have purple leaves because Ay is dominant allele which appear in the leaf colour instead of A2 which is a recessive allele. In the F1 generation, the dominant allele must appear in the shape and structure of the offspring whereas the recessive allele does not appear so offspring of purple leaves appear if plants have purple leaves cross with white leaves.

Blue jays and crows eat caterpillars and mice. if the number of blue jays increases, what are the two likely effects on other po
suter [353]

If the number of blue jays increases, the two likely effects on other populations are both the number of mice and the number of caterpillars will decrease.

<h3>What are two likely effects on other populations due to the increment in Blue jays population?</h3>
  • An organism that preys on other species in order to consume them as food is referred to as a predator.
  • Prey is a term used to describe an organism that a predator kills.
  • An ecosystem's ability to balance an expanding prey population depends on the interaction between predators and their prey.
  • Blue jays and crows both rely on mice and caterpillars as food sources, as indicated by the current circumstance.
  • Mice, caterpillars, and blue jays are the prey, while crows and crows are the predators. The two prey populations will decline if the number of blue jays rises.

Hence, both the number of mice and the number of caterpillars will likely drop as the number of blue jays rises, having two possible implications on other populations.

IgA is important for protection of mucus membranes such as in saliva, sweat, tears and gastric fluid.

IgE is active during allergic reactions and defense against infections.

IgD is found on the surface of lymphocytes and is activated upon contact with antigens.

IgG forms part of the secondary response to antigen and is also responsible for newborn protection.
