Explanation:
Skeletal muscle is attached to bones, is under voluntary control, and has a striated appearance due to the arrangement of actin and myosin filaments. Smooth muscle (visceral) is non-striated and involuntary, found in internal organs. Cardiac muscle is striated but involuntary, found only in the heart. Skeletal muscles are multinucleated.

Explanation:
Acidosis is a condition of decreased blood pH (7.45). Homeostasis is maintenance of stable internal environment. Apoptosis is programmed cell death. Acidosis can be respiratory (due to CO₂ retention) or metabolic (due to accumulation of acids like lactic acid or ketone bodies).

Explanation:
Adventitious roots arise from stem, leaf, or other non-root tissues, unlike taproots and fibrous roots that develop from the radicle. Examples: prop roots of banyan, stilt roots of maize, aerial roots of orchids. They can serve support, aeration, or additional absorption.
