Answer:
A habitat
Explanation:
A habitat is a natural environment which shelters living organisms of the same species. In a species habitat, species can be sheltered, fed and can also mate to reproduce offsprings. A habitat has both physical and biological characteristics. Representing the physical factors are soil, moisture, temperature range and intensity of light. While those representing the biological factors are the presence of prey and predators as well as other things. Most organisms or species adapt to strive which others might try to live up to their inbuilt habitat needs. A habitat does not necessarily refer to geographical area but can also be within the soil or inside of a branch or stem or other things which a living organism can live in. Homeostasis is essential in living organisms in a habitat because it helps to control and maintain them in optimum conditions which might have been necessary through adversary or habitat change.

Explanation:
The width of the confidence interval is 20-12 = 8 units. That cuts in half to get 8/2 = 4 which is the margin of error.
The center of the confidence interval is (12+20)/2 = 32/2 = 16. Add four onto this to get 16+4 = 20, which is the right endpoint. Subtract four from the center to get 16-4 = 12, which is the left endpoint.
Effectively, it's like saying "an archer aims for the value 16 on the number line, and the arrow could land as high as 20 or as low as 12".
Answer:
The photosphere is the visible surface of the Sun that we are most familiar with. Since the Sun is a ball of gas, this is not a solid surface but is actually a layer about 100 km thick (very, very, thin compared to the 700,000 km radius of the Sun).
