Explanation

Skin regulates body temperature through sweating, blood flow adjustment, and insulation.

It helps maintain homeostasis by releasing heat or conserving warmth as needed.

Explanation

The human cell contains 46 chromosomes.

These are organized into 23 pairs, where each parent contributes one chromosome to each pair, resulting in a total of 46 chromosomes in most human cells.

This number includes 22 pairs of autosomes and 1 pair of sex chromosomes, determining an individual's sex (XX for females and XY for males).

NOTE: DON'T BE CONFUSED about the pair and number of Chromosomes in the Human body

Total Chromosomes: 46

Pairs of Chromosomes: 23

It helps in breaking down proteins into amino acids and sugars into simpler forms for absorption.

Explanation

The Hindbrain is divided into three main parts:

• Medulla Oblongata (controls breathing, heart rate, and blood pressure)
• Pons (involved in controlling sleep and arousal)
• Cerebellum (coordinates movement, balance, and learning)

Explanation

 The eustachian tube is not part of the inner ear; the inner ear consists of the cochlea, semicircular canals, and the vestibule (which includes the utricle and saccule). 

Explanation

The respiratory center, responsible for controlling breathing, is primarily located in the medulla oblongata and pons within the brainstem.
