Consider statements about human anatomy: 1. The femur is the longest bone in the body. 2. The stapes is the smallest bone in the body. 3. The hyoid bone is attached to another bone by a joint. Which are correct? MCQ with Answer and Explanation

Explanation:
The cerebellum, located at the back of the brain below the cerebrum, coordinates voluntary movements, maintains posture, balance, and muscle tone. Damage leads to unsteady gait and tremors. The cerebrum controls thinking, memory, and voluntary actions. Thalamus relays sensory impulses, hypothalamus regulates body temperature, hunger, and endocrine functions. Cerebellum is often called the 'little brain'.

Explanation:
Transcription is the synthesis of mRNA from the DNA template strand by RNA polymerase. It occurs in the nucleus (eukaryotes). Replication is DNA duplication. Translation is protein synthesis from mRNA. Transformation is the uptake of foreign DNA by bacteria. The central dogma: DNA → RNA → Protein. Transcription produces mRNA, tRNA, rRNA. The mRNA carries the codon sequence for protein assembly.

Explanation:
The pancreas is a mixed gland; its exocrine part secretes digestive enzymes (trypsin, lipase, amylase), and its endocrine part (Islets of Langerhans) secretes hormones (insulin, glucagon). The liver continuously secretes bile, but bile does not contain digestive enzymes; it contains bile salts that emulsify fats. The gall bladder stores and concentrates this bile before releasing it into the duodenum. Thus, statements 1 and 3 are correct.
