The branch of biology concerned with the study of tissues is: MCQ with Answer and Explanation

Explanation:
The biceps brachii is a two-headed muscle located in the upper arm, responsible for flexing the elbow. The quadriceps femoris is a large, four-headed muscle group in the front of the thigh, extending the knee. The diaphragm is a dome-shaped skeletal muscle that forms the floor of the thoracic cavity and the roof of the abdominal cavity, crucial for breathing. All statements are correct.

Explanation:
The genetic code is a sequence of nucleotide triplets in mRNA called codons. Each codon consists of three consecutive nitrogenous bases and specifies a particular amino acid or a stop signal during protein synthesis. For example, AUG is the start codon (methionine). Anticodons are the complementary triplets found on tRNA molecules.

Explanation:
Spermiogenesis is the final stage of spermatogenesis, where the spherical, non-motile spermatids undergo a complex morphological transformation to become highly specialized, motile spermatozoa (sperm). This involves the formation of the acrosome, condensation of the nucleus, development of the flagellum (tail), and the shedding of excess cytoplasm. Spermiation is the subsequent release of these mature sperm into the tubule lumen.
