Snails have a diploid chromosome number of 22. after meiosis, the snail’s sperm or egg would have 11 chromosomes. how many chromosomes would the zygote have after fertilization?

11
22
33
46

The correct answer would be 22.

A zygote or fertilized ovum is produced by fusion of sperm and egg nuclei.  

Thus, both sperm and egg contribute their genetic material in the formation of a zygote.

This fertilization event restores the chromosomal number to that of the parent cell.  

Thus, the zygote of a snail would contain 22 chromosomes, 11 of which are contributed by sperm and other 11 are contributed by the egg.

the correct answer is c   with the systems

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
