Final answer:
The development of sweat glands is related to both body odor and acne. Sweat glands release sweat that includes organic compounds, contributing to bacterial decomposition and body odor. The oil glands in the skin can also produce sebum, which can cause acne when broken down by bacteria.
Step-by-step explanation:
The development of sweat glands is related to both body odor and acne. Sweat glands in the body help regulate body temperature by producing sweat, which contains water, salts, and organic compounds. The apocrine sweat glands, which are associated with hair follicles in densely hairy areas such as armpits and genital regions, release sweat that includes organic compounds. These compounds can contribute to bacterial decomposition and subsequent smell, leading to body odor. Additionally, the oil glands in the skin can produce sebum, which, when broken down by bacteria, can cause odors and contribute to acne.
