PLEASE HELP ME! I WOULD REALLY APPRECIATE IT

blue eye cats= B

yellow eye cats= b

black wing fruit  bat= W

white winged fruit bat= w

Explanation:

For any dominant trait, you use a capital letter (in this case i used the captial letters of the colors they were usuing)The captial letter will tend to go first so for the Blue eye cat the answer will be 'BB', meanwhile the yellow eyed cat will be 'bb' (because yellow is a reccesive trait) and the same goes with the fruit bat situation.    

i'm thinking (a) to keep sand in place; ////////////

explanation: a sand fence or sandbreak, like a snow fence, is used to force windblown, drifting sand to accumulate in a desired place. sand fences are employed to control erosion, sand dune stabilization, keep sand off roadways, and to recruit new material in desert areas.
