Alexander Graham Bell was an eminent Scottish-born scientist, inventor,
engineer and innovator who is credited with inventing the first practical
telephone.  His research on hearing and speech led him to experiment
with hearing devices.  Bell considered his most famous invention to be
an intrusion on his real work as a scientist and refused to have a telephone
in his study.  Many other inventions marked Bell's later life, including
groundbreaking work in optical telecommunications, hydrofoils and
aeronautics.

The radio transmitter and 'aerial' radio antenna were innovations of
Guglielmo Marconi.

Ihave never had a problem with someone answering questions.. just keep trying

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/
