Muscle tissue contraction is a response to .
a. low levels of melanin
b. signals from the nervous system
c. the integumentary system function
d. low levels of glycogen
e. neuroglial cells

b. signals from the nervous system

Explanation: Muscle tissue contract as a result of signals receive form Central nervous system.

Muscle contraction are of different type as they cause changes in length and tension.

If the muscle length decrease it is called Concentric, if the muscle tension changes but the length remain constant it is called Isometric.

Muscles contraction can occur as result of pressure exert by load or object. Also, it may occur as a result of pressure or load on the muscles by an object or load.

weathering is the answer.

a researcher conducts an experiment on the secretion of a particular hormone in mice. scientists inject mice with a substance that stimulates the production of the hormone. the scientists then test the levels of hormones produced by the mice. the tool used to measure the hormones consistently detects the levels at 10 points lower than the actual hormone levels in the mice. this tool makes measurements, but the measurements aren't .
