What is the 1st 2nd 3rd 4th 5th 6th and 7th layers of the inside of a leaf? plz asap

A leaf is made up of many layers and is surrounded by two. Upper epidermis, mesophyll, bundle sheath, vein, mesophyll, lower epidermis, and guard cells.

Cuticle, paliscade layer, spongy layer, guard cells, stomata, vascular bundle, lower epidermis, upper epidermis, mesophyll.

The answer would be c, white eyes are homozygous recessive. in the early 1900s, morgan conducted several experiments with vinegar  flies (drosophila). one  sample revealed an anomaly: a  white-eyed, single male fly. he attempted to breed this fly with the typical red-eyed females. the offspring were all red-eyed. using flies from this new generation (brother-sister pairs)  produced some red-eyed and a few white-eyed flies. the white-eyed were all male. in later experiments, he was able to produce white-eyed females. this proved that white eyes are not lethal to either sex (ruling out a and b). since the percentage of white eyes to red eyes is so low, white eyes are not a dominant trait. it would be a recessive trait.
