Question

Animals which possess cleidoic eggs exhibit?
A.External fertilization and internal development
B.Internal fertilization and internal development
C.Internal fertilization and external development
D.External fertilization and external development

Answer 1

Hint: Cleidoic eggs are the eggs of reptiles and birds. They are isolated from the environment by proteins, membranes and shells. The fertilization of reptiles and birds is internal, while development is external.

Complete answer:
External fertilization and internal development: External fertilization is a mode of reproduction in which the sperm of the male organism fertilizes the eggs of the female organism inside and outside the female. In contrast to internal fertilization, internal fertilization is the introduction of sperm through insemination, which then combines with the eggs in the female organism.
Internal fertilization: The characteristic of internal fertilization is that the sperm fertilize the female egg. These three methods include: ovo-fetus (the egg is laid outside the woman's body), ovo-fetus (the egg is laid in the female's body), and fetal egg (the egg develops in the egg and then is born live).
Internal fertilization External fertilization: To usually occur in an aquatic environment where both eggs and sperm are released into the water. Most external fertilization occurs during spawning, one or several females release eggs, and males release sperm from the same area at the same time.
External fertilization and internal development : The internal fertilization process takes place in the female body, and the offspring only develops in the female body, while in the external fertilization process, this process occurs outside the body in the external aquatic environment.

Hence the correct answer is OPTION(C)

Note: The internal fertilization process takes place in the female body, while the offspring only develops in the female body, while in the external fertilization process, this process occurs outside the body of the external aquatic environment. There are three types of internal fertilization: egg; egg. Viviparous; ovo-fetal.
