,What ability does muscle tissue have? - ANS Ability to contract and shorten.
What is muscle tissue classified as? - ANS Voluntary(skeletal muscles) and
involuntary(smooth & cardiac)
What is meiosis? - ANS The cell division that takes place in the gonads, i.e. the ovaries and
testes.
What two layers compose the skin? - ANS Epidermis and dermis.
What is the epidermis? - ANS The outermost protective layer of dead keratinized epithelial
cells.
What is the dermis? - ANS The underlying layer of connective tissue with blood vessels, nerve
endings, and the associated skin tissues.
What are the layers of the epidermis? - ANS Corneum

, What are the 2 types of sweat glands? - ANS ecrine & apocrine
What do ecrine sweat glands produce? - ANS Sweat. Regulate body temperature.
What do apocrine sweat glands produce? - ANS Secretions contain bits of cytoplasm from
cells, attracting bacteria that produces body odor.
What do sebaceous glands secrete? - ANS They secrete sebum through the hair follicles,
which lubricates the skin and prevents drying.
What secretion produces oil? - ANS Holocrine secretion.
What are sebaceous glands prone to during adolescence? - ANS Becoming clogged and
attracting bacteria.
What protein composes the hair and skin? - ANS Keratin
What makes the body's framework? - ANS Bone, cartilage, ligaments & joints.
What are the functions of the skeletal system? - ANS Support, movement, blood cell
formation, protection of internal organs, detoxification, muscle attachment, mineral storage. *A
