Answer:
The penguins are geographically close to each other
The penguins have similar amino acid sequences for Cytochrome B
The penguins look somewhat like each other
Explanation:
Both King penguin and Emperor penguin are closely related to each other because both lives on the same geographical location which is Antarctica. Both King penguin and Emperor penguin have similar amino acid sequences for Cytochrome B due to belongs from the common ancestor. Both King penguin and Emperor penguin have similar appearance and look very similar to each other with some differences in their shape which make them different species.
Importance:
Oxygen is the third most abundant element and constitute about 21% of the gases in earth's atmosphere. It is a key for generating energy in cellular respiration. In aerobic respiration, electron release in electron transport chain is culminated by oxygen, result into the production of chemical energy.
Oxygen obtained by human:
Human obtain oxygen through respiratory system by applying partial law of diffusion.The partial pressure of oxygen in atmosphere is higher than inside lungs, so oxygen move into lungs in exchange for carbon dioxide.
Oxygen obtained by flatworms:
Oxygen obtained by ferns:
