harkovskaia [24]

If given a chance to advice Mr. Smith, I would recommend him to minimize going out in the sun when it is at the peak of the morning but if not possible since he works under the sun, it would be good to put on sunblock with a highest SPF and use precautionary measures like using hats and wearing long sleeve to protect also the skin.  More water to hydrate, and vitamins for skin protection.

Which of the following best describes a nuclear fusion reaction?

Think of the words "nuclear fusion".

Nuclear = "relating to a nucleus"

Fusion = "joining"

So, nuclear fusion is the joining of two nuclei into one.

1. Muscles move tendons attached to bone by performing an action called _______.
REY [17]

1. Contraction

2. Actin

3. Tendons

4. Epidermis

5. Dermis

6. Acne

7. A nerve signal from the brain arrives at the intersection of the nerve and muscle cells and releases acetylcholine from the neuron. This triggers chemical changes in the muscle cell involving ions, including Ca2+. Calcium triggers the thick filaments, made of myosin, to attach to the thin filaments, made of actin, in the muscle cell, and the myosin pulls the actin toward the center of the muscle cell. ATP causes the release of the actin fibers, allowing the muscle to relax and the process to begin again.
