Answer:
Smooth muscle
Explanation:
- The smooth muscle is one of the three types of muscle present in the human body and other animals.
- The smooth muscle is called smooth because of its smooth appearance without any striations in its structure.
- The smooth muscle is made of the spindle-shaped cells characterized by a single nucleus.
- The smooth muscle cells are controlled by the autonomic nervous system and therefore is involuntary in its action.
The smooth muscle is present in the hollow organs and propels the substances through these hollow internal passages like in the alimentary canal of the digestive tract and urinary bladder.
Thus, the Smooth muscle is correct.
The answer is B., Natural Selection.
Weather certainly doesn't change populations, and genes only caused individuals in a population to be slightly ( genetically-wise ) different from the others. It does cause change, but not change in the whole population over time.
Natural disasters don't change the populations over time either. Natural disasters only caused change in their environment, at most.
So, the only answer left is natural selection, and it makes sense too!
Natural selection is the process where the individuals with better traits suited to survive in that specific environment live on and give those good traits to their offspring.
The individuals with less suited traits to survive will die out, and will not be given an opportunity to reproduce and pass on their less suited traits, so over time, the population will increase of individuals with better suited traits to survive and the individuals with less suited traits will eventually die out, therefore making the entire population change.
