soil. Swamps, marshes, and other wetland areas help to control flooding because they naturally hold water. Wetland regeneration
gizmo_the_mogwai [7]
Restoring farmlands to wetlands consists of a lot of pro and cons. Firstly, they should consider that wetlands will greatly filter carbon dioxide from the atmosphere and reduce greenhouse gases. Wetlands restoration would probably affect the lives of the nearby human residents negatively. This is due to the fact that wetlands provides an optimal habitat to wild animals especially dangerous carnivores like alligators. The regeneration project will expand the habitats of animals, and clean the water system but it will remove the nutrients from the soil.

the diploid number of chromosomes in horses is 64. what is the haploid number of chromosomes in horses?
OlgaM077 [116]
The haploid number of the chromosomes should be 32. 

Diploid number means that they have the complete sets of chromosomes in their cells, these cells are usually found in somatic (body) cells and different organisms have a different number. For example, a human somatic cell has 46 chromosomes, such as a muscle cell, or a skin cell etc. 

Meanwhile, haploid number means that the number of chromosomes in the cell only have half of the chromosome number than that of the diploid cells. These haploid cells are usually found in gametes of sexually reproducing organisms, such as human, we have 23 chromosomes in our sex cells. This is important because we have to make sure the chromosome number of offsprings are not doubled, as during sexual reproduction, male and female gametes fuse together to form a zygote. 

Therefore, to calculate the haploid number of a cell, we can divide the diploid number by 2, which is 64/2, and the answer would be 32.
