An organism has a diploid number of 102. what is the organism's haploid number?
a. 51
b. 102
c. 408
d. 204

51

Explanation:

An organism is said to be diploid if he/she possesses two complete sets of chromosomes and the number of such sets is the diploid number.

The haploid number refers to the number of chromosomes in one set, that is it is half the diploid number.

Since in the given question the diploid number is 102, the haploid number must be 1/2 X 102 = 51.

increase soil erosion                                             reduce soil erosion

cattle grazing                                                         hydroseeding

deforestation                                                         contour plowing

                                                                                planting vegetation

plant roots basically hold the top soil

together and stop soil erosion because

in such situation top soil is not removed

during flood but cattle grazing causes

soil erosion because cattle consume the

grasses and herbs and top soil is exposed.

same situation occurs because of

deforestation, the trees and plants are cut

down to expose top soil which causes soil

erosion
