Imagine that two groups of neurons (a& b) send their signals to another group of neurons (c) action potentials generated simultaneously by all the neurons of group a lead to a response in c such that a select number of neurons in group c are activated ( number of activated neurons = c1); action potentials generated simultaneously by all the neurons of group b lead to a response in c such that c2 is the number of activated neurons. what might the magnitude of the response be in c if action potentials were generated simultaneously by all the neurons in both groups a & b? can it be bigger than, smaller than, or equal to ( c1+ c2)? why?

Muscles in the body us with a lot of things for example, if i wanted to lift a heavy box and had no muscle i would just collapse where i was because of the fact muscles hold us together. overall they are 650 muscle in the human body, all of them have different purposes and ways to keep us together. there are three types of muscle in the body skeletal, smooth, and cardiac muscle. skeletal muscle are attached to the bone and with movement. smooth muscle, this is found in the wall of our organs, such as our stomach, this muscle with movement   as well, without this muscle, we would only be allowed to eat small amounts. the cardiac muscle is the heart muscle and probably the most important one. these are only found in the walls of the heart and the heart pump blood to the other parts of your body. we have two different types of muscle fibers, slow twitch and fast twitch. slow twitch muscles enable long-endurance feats such as distance running. fast twitch fatigue faster but are used in powerful bursts of movements like sprinting. there are three different types of muscle contractions concentric, eccentric, isometric. concentric contraction causes muscles to shorten, thereby generating force.   eccentric contractions cause muscles to elongate in response to a greater opposing force. isometric contractions generate force without changing the length of the muscle.: //athleticquickness.com/muscle-contraction-types-part-1/

"observation" would be the correct answer

Cells are the smallest. bones, muscles, and tendons are all made up of different type of cells.hope my answer you : )

D. not all can afford without health insurance
