Group 1a element sodium combines with group 7a element chlorine to form sodium chloride or table salt. based on this information, this expression is true about the electronegativity values of these two elements.

a) na > ci
b) na < ci
c) na = ci
d) we cannot make a prediction with data provided.

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. 

  like australopithecus afarensis; probably the direct ancestor of this group. africa: 5.8 to 4.4 million years ago. 

Advection fog occurs when warm air blows over a cold surface like snow and since tropical water is warm advection fog rarely forms over it
