When does a plant start producing flowers

the farther away the object is from the central star (the sun) it's gravitainal pull on the object is weaker when it is farther

explanation:

the "power" of a lens is its resolution power, or its ability to distinguish between to closely located points. with the low power lens, it is likely you will see the rough form of the hay and maybe some movement of dots around the hay. however, when observed with the high power lens, the detailed features of the hay become visible and the microbes being grown are more clearly visible.

i hope this you

d. changes in climate and historical records

hope this
