Answer:
Internal Fertilization: Mammals,birds and reptiles in them the mode of fertilization is internal
External Fertilization: Amphibians and fishes used external fertilization.
Egg laying Animals;Birds,reptiles and some mammals platypus lays eggs.
Explanation:
Fertilization is a process in which a female egg (Ovum) and male egg (sperm) unite to form a zygote.A zygote is a fertilized egg which grows within an embryo.The process of fertilization is important in eukaryotes such as animals, humans,birds and plants. Fertilization divides a cell into many daughter cells by the process of mitosis and meiosis.It doubles the chromosome numbers.Fertilization are of two types internal and external.
As solar energy interacts with carbon dioxide, water vapor, and several other gases in the troposphere, it warms the troposphere process known as the Green house effect.
- Troposphere is the lower most part of the earth's atmosphere comprises of Nitrogen, Oxygen, Argon, Carbon dioxide and Water vapour.
- Carbondioxide, water vapour and other gases like methane are concentrated highly in the Trophosphere due to some human activities (Industrial revolution).
- Such excess Green house gases forms a shield layer which retains the heat by trapping the long wave radiation of solar energy in troposphere. As a result, global warming and abnormal weather conditions occurs in the planet.

Explanation:
<u>Answer:</u>
<em>The two major processes by which bacterial populations produce genetic diversity are gene transfer and mutation.</em>
<u>Explanation:</u>
Gene transfer in bacteria occurs through conjugation. In the process of conjugation, the plasmid gets transferred from bacteria to another. Mitosis leads to the formation of two identical individuals.
In this process, the chromosome and the DNA content of the daughter cell remains the same as the mother cell. Bacteria also divides by the process of binary fission.
