isometric contraction is when the joint angle and muscle length do not change during contraction
In an isotonic contraction, tension remains the same, while the muscle's length changes
Answer: I have been asked to give a speech to your class. I am concerned that if you refuse the opportunity, you may feel disappointed in yourself. However, I am also afraid that you'll be too nervous to speak in front of a large group. A positive of doing the speech would be self improvement and you would grow from the experience further improving self confidence, and even bravery. A negative of doing a speech would be stress and the time it would take to create the speech. A positive of not doing the speech would be time and freedom. A negative of not doing the speech could be later on regretting the decision for missing out on a chance to grow and improve. I would probably chose to take that chance and do the speech because it won't hurt to learn a bit. Practicing talking in front of big crowds can also help someone become friendlier. The best way to move past the stress of making a decision would be to change the meaning of the negative energy. For example if I were feeling nervous I would channels that energy into being exited and it would help motivate me to move on and create this speech.

The matter in our body has been connected to earth by micro alient cells that connect to unknown species and such as dirt.
The glial cells forming myelin sheaths are called oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system. The gaps (approximately 1 micrometer wide) formed between myelin sheath cells long the axons are called Nodes of Ranvier.
hope this helps :p
