Suggest reasons for the color patterns of the frog and its lack of color on the ventral surface.

Answers

Answer:

To save itself.

Explanation:

The color patterns of the frog and its lack of color on the ventral surface allows the frog to protect itself from their predators because the frog changes its colour and the predators are unable to see them. The color patterns of frogs and their lack of color on the ventral surface allow frogs to escape from their predators. If the frog does not change its colour, the predators will see them and the frog will be catch by its predators and feed on them so this is the reason that frog changes colour or the presence of colour patterns.

A. They are multicellular, but bacteria are unicellular.
B. They are thought to have separate paths of evolutionary
development
C. They are able to perform endosymbiosis, but bacteria are not.
D. They have no similar characteristics.

Answers

Answer:B

Explanation:

Archaea is in a different domain from bacteria because they are thought to have separate paths of evolutionary development. Therefore, the correct statement is option B.

What are the differences between archaea and bacteria domains?

Archaea and bacteria are both prokaryotic organisms, but archaea are more closely related to eukaryotes than bacteria. Archaea have unique  lipid membrane and cell wall components that are different in composition than those found in bacteria.

These differences suggest that archaea and bacteria evolved to have separate paths of evolutionary development early in the history of life on Earth and then classified into Archaea and Bacteria domains.

Based on the phylogenetic tree constructed by researchers, the tree has classified life into three domains which are Archaea, Bacteria, and Eukarya These domains are based on their fundamental genetic and biochemical differences.

Therefore, archaea and bacteria are in a different domain because they followed separate paths of evolutionary development.
