Question

10). Internal and external fertilization both A) produce zygotes. B) occur only among invertebrates. C) occur only among terrestrial animals. D) depend on the use of intromittent copulatory organs. E) occur only among birds.

Answer 1

Internal fertilization occurs most often in land-based animals, although some aquatic animals also use this method. There are three ways that offspring are produced following internal fertilization.

Step-by-step explanation:

Internal fertilization occurs most often in land-based animals, although some aquatic animals also use this method. There are three ways that offspring are produced following internal fertilization. In oviparity, fertilized eggs are laid outside the female's body and develop there, receiving nourishment from the yolk that is a part of the egg.

This occurs in most bony fish, many reptiles, some cartilaginous fish, most amphibians, two mammals, and all birds. Reptiles and insects produce leathery eggs, while birds and turtles produce eggs with high concentrations of calcium carbonate in the shell, making them hard. Chicken eggs are an example of this second type.

Answer 2

Answer:a.produces zygote

Explanation: reproduction is tge process where organisms both plant and animals produce similar organisms to their,in order to continue their existence.reproduction could be internal or external.the male organism may directly deposit sperm into the female reproductive tract to fertilize the egg or it may fertilize the egg outside of the female.in both cases,a zygote is formed From the fusion of both male and female gamete.this zygote undergoes several mitotic Division to become a matured organism.

External fertilization occurs in fishes and Amphibians eg frogs. and internal reproduction occurs in mammals and birds
