The answer is B. the right hemisphere of the cerebrum.
It is known that the left hemisphere of the cerebrum is responsible for control of the right side of the body and that the right hemisphere of the cerebrum is responsible for control of the left side of the body. Therefore, left hand is controlled by the right hemisphere while right hand is controlled by the left hemisphere of the cerebrum.
the dense connective tissue is a scar tissue. It doesn't exert forceful contraction like muscle. The muscle as a whole is still functional although the contraction will be weaker.
The muscle is still functional because the connective tissue only replaces the damaged parts of the large muscle.
Alcohol can pass directly into the bloodstream from the mouth or stomach is a true statement.
On consumption of alcohol it travels from mouth to stomach, then into the circulatory system, kidney, liver, lungs and brain. Alcohol being a small molecule does not need any digestion in stomach and passes to the bloodstream directly in an empty stomach. When food is present in stomach, the absorption rate is reduced but is not stopped.
Once the alcohol is in the bloodstream, it gets evenly distributed throughout the body.
Answer:
mitochondria is the powerhouse
Answer:
a It has membrane-bound organelles
b It converts stored energy to use for cellular processes
Explanation:
Prokaryotic cells lack membrane-bound organelles such as a nucleus and mitochondria, that are present in eukaryotic cells. However, they do have a cell membrane that separates the cell from the outer environment.
Prokaryotic cells do not have mitochondria to break down stored material into energy, instead they obtain their energy from light or chemical sources. This is in contrast to eukaryotic cells, which can break down sugars to produce energy.
Single celled prokaryotes and eukaryotes can both possess flagella
