Non­renewable resources mean it takes a longer time for the earth to produce it than the rate at which we use it. true false

This is true because we use these resources up faster than we can re-produce them.

I’ve personally felt invisible all my life, especially when a friend turned out to be fake and didn’t seem to take any type of interest in what i said or any type of input i said. being invisible is a terrifying feeling to experience due to the fact you feel like no one sees you and just sees you (sorry if that doesn’t make sense). it’s like a deep emptiness that no one can fill, just you; you have to fix that emptiness by yourself and you don’t really want , or in some cases want to be invisible. i can see many invisible people when they intentionally stay away from people that can potentially hurt them in any way. also, when a person intentionally breaks off a connection so they aren’t seen by people.hope it

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/
