Biology

Ulleksa [173]3 years ago
5 0
To breath in the air, frog lowers the floor of the mouth. That causes throat to expand and nostrils to open. The air enters the mouth through nostrils and after that nostrils close. The floor of the mouth contracts to push the air into the lungs. To breath out the air, the floor of the mouth is lowered again and the air is pushed into the mouth. Nostrils open again and the air leaves the mouth.

If a natural disaster caused all warbles to go extinct, why would the natural disaster not kill all living organisms?
likoan [24]

Answer:

Living organisms that are able to adapt to the environment (natural disaster) will increase in number while the ones such as warbles who can't adapt will die and go into extinction.

Explanation:

Natural selection can be defined as a biological process in which species of living organisms having certain traits that enable them to adapt to environmental factors such as predators, competition for food, climate change, sex mates, etc., tend to survive and reproduce, as well as passing on their genes to subsequent generations.

Simply stated, natural selection entails the survival of the fittest. Therefore, the species that are able to adapt to the environment will increase in number while the ones who can't adapt will die and go into extinction.

Additionally, due to genetic variation within populations, some living organisms have a better chance of possessing good or beneficial traits being passed from the parent organism to her offsprings which enables them to survive a natural disaster.

Hence, if a natural disaster caused all warbles to go extinct, the natural disaster may not kill all living organisms due to natural selection.
