(Elephants Can Make News)
What is the function of epithelial cells? - CORRECT ANSWER-Cover, line, and protect the
body and the internal organs.
What is the function of connective tissue? - CORRECT ANSWER-Framework of the body.
Provides support and structure to organs.
What is neuroglia? - CORRECT ANSWER-The neurons and connective tissue cells that
compose nerve tissue.
What ability does muscle tissue have? - CORRECT ANSWER-Ability to contract and shorten.

involuntary(smooth & cardiac)
What is meiosis? - CORRECT ANSWER-The cell division that takes place in the gonads, i.e. the
ovaries and testes.
What two layers compose the skin? - CORRECT ANSWER-Epidermis and dermis.
What is the epidermis? - CORRECT ANSWER-The outermost protective layer of dead
keratinized epithelial cells.
, What is the dermis? - CORRECT ANSWER-The underlying layer of connective tissue with
blood vessels, nerve endings, and the associated skin tissues.

What do ecrine sweat glands produce? - CORRECT ANSWER-Sweat. Regulate body
temperature.
What do apocrine sweat glands produce? - CORRECT ANSWER-Secretions contain bits of
cytoplasm from cells, attracting bacteria that produces body odor.
What do sebaceous glands secrete? - CORRECT ANSWER-They secrete sebum through the
hair follicles, which lubricates the skin and prevents drying.
