Cells are made up smaller units called organelles that undertake various critical roles in the activities of the cell. Some of these organelles include, mitochondria whose major function is formation and production of energy in the form of ATP, Ribosome is an organelle involved in the protein synthesis, lysosome is involved in the destruction of old and worn out tissues and organelles, Golgi apparatus or complex helps in transportation, modification and packaging of secretions such as proteins and lipids. Therefore, alcoholism affects the activity of lysosomes in the liver since they are tasked in the digestion of proteins using hydrolytic enzymes.

Explanation:
Skeletal muscles are the multinucleated muscles with striations and are attached to the bones (skeleton). The main function of skeletal muscles is to generate the voluntary movement of the body or body parts. The skeletal muscles of face, rectum, and urinary bladder generate their voluntary movement as per the will of the organism. On the other hand, blood vessels are lined with smooth muscles with spindle-shaped cells.
For example, the muscles present in the subcutaneous layer of the skin of the face are responsible for various facial expressions. Contraction of these facial muscles brings about the movement of skin of the face to generate a wide variety of emotions. Smooth muscles of blood vessels are involuntary in nature.
Vasodilation and vasoconstriction as brought about by smooth muscles of blood vessels are regulated by the autonomic nervous system. Under the conditions of lower blood pressure, contraction of smooth muscles of blood vessels restore the reduced blood pressure. On the other hand, when the blood pressure rises above the normal range, the smooth muscles of blood vessels relax to dilate them and to lower down the blood pressure.

The basis of classification of
Linnaeus’ system is sexual reproduction. The
only "natural" taxon in Linnaeus' system is the species. Species defined
as a population with viable, fertile reproduction are separated from
interbreeding with other species.
