Populations evolve, individuals do not. It is incorrect to say that individuals adapt to their environment because adaptation occurs as a result of random mutations. Changes in the individual during its lifetime, such as phenotypic plasticity, is not adaptation.
Answer:
No oxygen is required.
Explanation:
This pathway for forming ATP needs no oxygen and the ATP that is produced are in very low concentration. The low amount of ATP production occurs when the cell goes for anaerobic respiration in which the cell produces less ATP. This type of ATP production occurs only when the body requires ATP quickly so that's why the body uses this type of respiration during exercise and running activities etc.
The central vacuole holds all of the water for the plant, and when the plant has had enough water, it swells. When the central vacuole swells with all of the water, it pushes against the cell wall. This is called turgor pressure, and it gives the plant the support it needs to stay upright.
<u>Answer</u>:
Vestigial organs are those organs that were present in the past ancestors but absent in their present generations. Vestigial organs are not leftover of evolution because they are evolved to perform a different function.
<u>Explanation</u>:
For example, an appendix is considered as a vestigial organ but it helps in storing good bacteria and plays a vital role in the immune system. These vestigial organs are the product of changing the environment and adaptation to the changing environment. Due to natural selection some specific traits have been passed down to generations which helped the animals to survive in those conditions. The other examples of vestigial organs are wisdom teeth coccyx, tonsils, several genes in the chromosomes and our hair.
Answer:
Most frogs see well only at a distance, but they have excellent night vision and are very sensitive to movement.This peripheral vision helps them spot predators and prey. Humans and other mammals focus images by changing the shape of the lens. Like a camera lens, frog eyes focus by moving the lens back and forth.
