The organ of the human body that stores glycogen as a reserve carbohydrate is: MCQ with Answer and Explanation

Explanation:
The ball and socket joint (e.g., glenohumeral, hip) allows movement in multiple axes (flexion, extension, abduction, adduction, rotation). The rounded head of one bone fits into the cup-shaped socket of another. Hinge (elbow, knee) allows movement in one plane, pivot (neck) allows rotation, gliding (wrist) allows sliding.

Explanation:
Mendel's first law (law of segregation) states that two alleles of a gene separate during gamete formation (meiosis) so that each gamete receives only one allele. This is due to the separation of homologous chromosomes in anaphase I of meiosis. Fertilization restores the diploid number. This law explains the 3:1 phenotypic ratio in monohybrid crosses. Mitosis maintains the allele pair.

Explanation:
ATP (adenosine triphosphate) is the immediate energy currency for cellular processes. Hydrolysis of its high-energy phosphate bonds releases energy. Glucose and acetyl CoA are fuels, NADPH is an electron donor for biosynthesis. ATP is generated by substrate-level phosphorylation and oxidative phosphorylation.
