Answer:
In this given statement , the plastic base becomes negatively charged because plastic is an insulator . And the metal cup does not become charged because metal is a conductor.
Explanation:
<u>Reason behind , why plastic base becomes negatively charged -:</u> When a plastic base is rubbed with a dry cloth in the metal trophy, electrons are shifted from one material to the other. Thus, the substance that gains electrons (which is the plastic base) becomes negatively charged. thus , the plastic is an insulator , which causes charge (negative ) by rubbing.
<u>Reason behind , why the metal cup does not become charged -:</u> The metal cup is a conductor, and the surplus charge on the metal flows to the person who charges the cup and to the ground so that it is not charged. Thus, rubbing a metal can trigger hand\finger injury because metals generate excess heat in rubbing .
<u>Answer:</u>
Area receives little precipitation.
<u>Explanation:</u>
- Arid climate is a type of climate that receives less than 25.4 cm of rainfall throughout the year.
- Desert climate is called as arid climates. Rainfall in arid climates is usually irregular but when rainfall occurs then it will be huge with thunderstorm.
- Many plants and animals found in that climate adopt themselves from rare rainfall and they remain inactive during most of time of the year and active only on the time when rainfall occurs.
Answer:
Yes, you are right for both.
The main difference between population and community is that a population is a group of individuals of a particular species living in a particular ecosystem at a particular time whereas a community is a collection of populations living in a particular ecosystem at a particular time.
It is both a Parasitic and segmented
