Answer:

<em>The potential environmental impacts associated with solar power—land use and habitat loss, water use, and the use of hazardous materials in manufacturing—can vary greatly depending on the technology, which includes two broad categories: photovoltaic (PV) solar cells or concentrating solar thermal plants (CSP).</em>
Explanation:
I just answer the second question
Answer:
(1) it is transparent so it makes the reading difficult. (2) it is volatile. (3) it is a poor conductor of heat. (4) it has a higher specific heat capacity, so it absorbs more heat from the body with which it is kept in contact. (5) Water cannot be used in thermometer because of its higher freezing point and lower boiling point than other liquids . If water is used in a thermometer , it will start phase change at 0oC and 100oC and will not measure temperature , out of this range .
PLEASE READ CAREFULLY AND PLEASE MARK AS BRAINLIEST :)
They help scientists explain concepts that are difficult to observe.
<h3><u>Answer;</u></h3>
A. Skeletal muscles, which are made of fibers, nerves, and blood vessels, contract in order to make the body move.
<h3><u>Explanation</u>;</h3>
- <em><u>Muscular tissues functions in movement and locomotion through its direct connection with the skeletal system. </u></em>
- <em><u>Skeletal muscles are responsible for moving the body. The skeletal muscle contractions pull on tendons, which as attached to bones. When the skeletal muscle contraction causes the muscle to shorten, the bone and thus the body par will move. </u></em>
- <em><u>Skeletal muscles also provide structural support for the entire body. </u></em>
