Answer:
Their vision underwater is better than a humans, but inferior on land. Lenses are enlarged and almost round, adapted for focusing on light that is refracted upon entering water. They use the light to continue swimming which is why researchers think they use visual cues because of how quickly they react to the amount of light in the water
Answer:
The correct answer will be option-C.
Explanation:
The muscle contraction occurs as a result of the sliding of the myofilaments made up of thin actin filaments and thick myosin filaments. The actin contains a binding site for the myosin which is covered with the tropomyosin-troponin complex proteins.
The troponin contains a binding site for the "calcium" which is released from the sarcoplasmic reticulum in response to the nerve signals. The calcium binds the troponin and causes conformation changes in tropomyosin which exposes the myosin-binding sites to bind myosin. The myosin binds and forms cross-bridge and cause muscle contraction.
Thus, Option-C is the correct answer.
Eons, Eras, Periods, and epochs are all examples of Units of time on the Geologic Time Scale.
It’s number 1 because solids don’t have large spaces and they don’t take the space of container like liquid and gas would and they have low kinetic energy
