If a haploid sperm cell contains 8 chromosomes, it comes from an animal that has chromosomes. 4 8 12 16

It would have to come from a animal that has "16" chromosomes or the fourth option. When a person or animal reproduces to make a baby that would half the amount of chromosomes half from his/her mother, half from his/her father. In this case it would come from a animal that has 16 chromosomes since how tyou have to split the amount to get 8.

Hope this helps!

answer: tributaries flow into rivers.

wetland is a biome that develops when the water gets accumulated in a land exhibiting a huge depression. these form either seasonally or permanently. the water in the wetland comes from rivers, lakes, ocean, flood, rain or other sources. the wetlands includes mangroves, marshes and peatland.

tributaries flow into the rivers develops a wetland because such water will get deposited in the depression and will restrict the original flow of tributary water. hence, water with low drainage current combines with the river water.
