Identify the earth motion that provides the basis for our system of local time and time zone

1 answer:

3 0

I think the Rotation of the earth provides a basis for our system of local time. The earth rotates on an imaginary axis at a rate of 15 degrees per hour. Meridians of longitude are the basis for time Zones. As Earth rotates different parts of Earth receive sunlight or darkness, giving us day and night. Having time Zones means that no matter where you live on the planets, your noon is the middle of the day when the sun is highest, while midnight is the middle of the night.

Using a microscope, a student observes a small, green organelle in a plant cell. which energy transformation most likely occurs

olganol [36]

The green organelle is the <u>CHLOROPLAST</u>.

It contains chlorophyll, which absorbs light energy and convert it into chemical energy, in form of ATP and NADPH. This reaction takes place in this organelle only. And since chlorophyll is a pigment delivering green color, so its chloroplast. The process of conversion of this energy is called as photosynthesis.
