Answer:
B) When an electrically charged object comes close to an uncharged object, it will attract it.
Explanation:
Suppose that you rubbed a balloon with a sample of animal fur such as a wool sweater or even your own hair. The balloon would likely become charged and its charge would exert a strange influence upon other objects in its vicinity. If some small bits of paper were placed upon a table and the balloon were brought near and held above the paper bits, then the presence of the charged balloon might create a sufficient attraction for the paper bits to raise them off the table. This influence - known as an electric force - occurs even when the charged balloon is held some distance away from the paper bits. The electric force is a non-contact force. Any charged object can exert this force upon other objects - both charged and uncharged objects.
Any charged object - whether positively charged or negatively charged - will have an attractive interaction with a neutral object. Positively charged objects and neutral objects attract each other; and negatively charged objects and neutral objects attract each other.

Answer:
Plasma plays an essential role of transporting nutrients and waste.
Explanation:
The largest constituent of the blood that comprises 55 percent of its entire constituents is the plasma. It is a light yellow liquid, which along with water transports enzymes and salts to different parts of the body. Plasma primarily plays an essential role in transporting hormones, nutrients, and proteins to different body parts.
Apart from this, plasma also carries waste materials withdrawn from the cells and discharges it out of the body.
Hmm... after some long thinking about this I would have to go with land. After land has been frozen, it thaws (<span>become liquid or soft as a result of warming.) Heat cannot "thaw" because it is apart of air. Water cannot "thaw" because it is already a liquid. Makes sense? I hope this helps! P.S. (A brainliest wouldn't hurt) ;)</span>
