The hormone that promotes the absorption of glucose into cells is: MCQ with Answer and Explanation

Explanation:
Cardiac muscle cells are striated, branched, and connected by intercalated discs containing gap junctions for synchronized contraction. They are involuntary. Multinucleated syncytium is typical of skeletal muscle. Spindle-shaped non-striated cells characterize smooth muscle. Voluntary control is for skeletal muscle. Intercalated discs allow rapid ion passage, enabling the heart to function as a syncytium.

Explanation:
Prokaryotic DNA is typically circular, double-stranded, and found in a nucleoid region without a nuclear membrane. It is not associated with histones (though some Archaea have histone-like proteins). Plasmids are extra-chromosomal DNA. Eukaryotic DNA is linear and complexed with histones. This difference is fundamental in cell classification.

Explanation:
Bile is continuously synthesized by hepatocytes in the liver. It contains bile salts, bile pigments, cholesterol, and phospholipids. The gall bladder merely stores and concentrates bile, releasing it upon eating. The pancreas produces digestive enzymes, duodenum is part of the small intestine. Bile emulsifies fats.
