What would happen first if guard cells in a plant stopped working?.

the correct option is C

C.Stomata would not open and close.

This is because guard cells play an important function of controlling stomata. the ensures that stomata are open during the day and closed during the night for the purposes of photosynthesis. The stomata are the pores that are found on the under surface of a plant leave, whose role is gaseous exchange.

it cools slower in the earth meaning the crystals have more time to form than lava on the surface

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )
