The type of joint that allows the head to rotate from side to side is: MCQ with Answer and Explanation

Explanation:
Insulin lowers blood glucose by promoting cellular uptake and glycogen synthesis, opposing glucagon which raises glucose. Cortisol and epinephrine are counter-regulatory hormones that increase blood glucose.

Explanation:
Smooth endoplasmic reticulum (SER) lacks ribosomes and synthesizes lipids, steroid hormones, and detoxifies drugs. Rough ER synthesizes proteins.

Explanation:
Epistasis is a form of gene interaction where the expression of one gene (the epistatic gene) masks, suppresses, or modifies the expression of another non-allelic gene (the hypostatic gene). This alters the expected Mendelian dihybrid ratio (9:3:3:1) into modified ratios like 9:7 (complementary), 9:3:4 (recessive epistasis), or 12:3:1 (dominant epistasis). Pleiotropy is one gene affecting multiple traits, and linkage is genes being on the same chromosome.
