While doing exercise, one can control skeletal muscles only.
The body has three kinds of muscles, that is, skeletal muscle, cardiac muscle, and smooth muscle. The skeletal muscles are linked with the bones of the skeleton, that is why these are under control and are known as voluntary muscles.
On the other hand, the smooth muscles like skeletal muscle can never be under control. These muscles helps in pushing substances, like blood or food through organs. The cardiac muscle is also an involuntary muscle, which is found only in the heart. These muscles helps in contraction of the heart and can never be controlled.
The largest elliptical galaxies can be over a million light-years in diameter. The smallest "dwarf elliptical" galaxies are less than one-tenth the size of the Milky Way! Elliptical galaxies have very little gas and dust. Since stars form from gas, little star formation occurs in elliptical galaxies.
A and B don’t even make sense, (small doesn’t equal more contact or more space) C doesn’t either, (if it’s large it’s gonna have more contact space) so the best answer for me would be D. It’s the only one that seems logical.
False. renewable energy is any resource that can be replenished. period.
Answer:
The correct answer is - C. members of different populations can no longer meet successfully.
Explanation:
Reproductive isolation is the process that occurs when two or more species or populations are not able to interbreed. The mechanisms or properties that are used to preventing individuals of separate species from mating called Reproductive isolation mechanisms.
The different barriers can cause this reproductive isolation such as different mating seasons. These barriers could be behavioral or temporal or ecological isolations.
