Are found in the stroma of chloroplasts small coins that provide energy. numerous mitochondrial membranes. stacks of thylakoids called grana. organelles called eukaryotes

The correct answer is small coins that provide energy

Explanation:

Small coins structures are found in chloroplast which are termed as thylakoid.There are stacks like arrangement of thylakoids within the granum.

    The Surface area of thylakoids is being increased by grana as a result more light is absorbed by the chloroplast.

   The thylakoid of granum is the site of light reaction.

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.

c.more precipitation,but only when emission levels.
