Answer:

B. Internal and external

Explanation:

The first egg has a calcareous shell, so we can imagine it is a dry and hard shell, and the egg has a large amount of yolk. These are characteristic of an egg generated from the internal fertilization, where the union of gametes occurs within the animal's body. During copulation the male uses his genitals or copulators to release sperm into the female's body, which results in an egg similar to the one described in the above question. Birds have this type of fertilization.

The second egg has a wet appearance, with gelatinous substances on its surface. These are characteristic of eggs resulting from external fertilization, where gametes fuse outside the female's body in the environment. In external fertilization, there must be water for the male gametes to move to the female. In addition, males need to eliminate large numbers of gametes to ensure they reach the eggs. Fish have this kind of fertilization and this kind of egg.

How could the tomato plant’s response to being eaten by a hornworm caterpillar be described as a function of homeostasis?
Ad libitum [116K]

Answer:

The required answer is given below:

Explanation:

This can be clarified with the idea of induced resistance. it is the capacity of a plant to react to the specific compound delivered from the damaged body parts, The dispersion of the synthetic animates all different plants parts and different plants to be less delectable and thusly not wonderful to eat. In this manner the more the degree of harm to the plant, the higher the volume of synthetic compounds delivered, and consequently the less delicious the plants and lower the harms negative criticism instruments. Since this reestablished the plants to moderately consistent inner environments, this is homeostasis.

Hornworm caterpillar harms tomatoes plants leaves, leaving holes. When a tomato plant is eaten, it discharges a compound substance called methyl jasmonate. The last would be gotten by adjoining plant parts or other tomato plants. The open tomato plants hence turn out to be less scrumptious. Subsequently, the caterpillar in the wake of crushing the underlying aspect of the tomato plants would not have the option to proceed with the taking care of and in this manner feed on each other prompting their death, turning them to cannabis caterpillars.  

Since trying to keep up the generally consistent interior condition plant discharges methyl jasmonate to forestall further harm and in this manner guarantees the soundness of the plant.
