Ineed plzzz i'm taking a test

a. crossing over
b. genetic drift
c. law of dominance
d. random segregation
e. independent assortment
sexual reproduction promotes genetic variation. one way variation occurs is via the production of gametes during meiosis. sexual organisms are the product of sperm and egg, receiving chromosomes from both parents. but what mechanisms are at work during meiosis to promote genetic variation? review the prompt and select all that apply.
a) a and b
b) a, d, e
c) a, b, c, e
d) a, b, c, d, e

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

not sure if this is what you'r looking for eubacteria and archaebacteria

a. to encourage apoptosis

glacial erosion, the picking up and movement of earth beneath a glacier, is also referred to as plucking. erosion and transportation of individual pieces of bedrock, especially large "joint block occur as a result of this glacial erosion. plucking is type of erosion in which rocks become frozen into the bottom and sides of the glacier.as the glacier moves downhill it 'plucks' the rocks frozen into the glacier from the ground.
