Meiosis contributes to genetic variation due to which of the following characteristics of the process?
Homologous chromosomes move to opposite sides of the cell to form new nuclei.
Gametes that contain half the genetic information are formed.
O The process begins with one diploid cell containing two copies of each chromosome.
When homologous chromosomes split, sections of chromosomes can switch places.

Kelly ran electricity though a sample of water using electrolysis. the water changed into two gases, x and y. it was not possible to break down the gases x and y into simpler particles.

Ais a landform that is formed at the mouth of a river from the deposition of sediment carried by the river as the water flows.

The kidney filters potentially toxic substances in the blood, and thus “clears” the blood of those substances. this clearance function is dependent upon and proportional to the diffusion gradient of the substance across filtering capillaries, i.e. if the concentration of the substance is doubled, twice as much will be cleared from each ml of blood that is filtered. suppose that the body produces a constant amount of a substance x per unit of time. the kidneys eliminate substance x at a rate directly proportional to the concentration of the substance and the volume of blood cleared each minute (c): elimination = c × [x], where [x] is the steady-state concentration of substance x. imagine an individual with an initial concentration of x equal to [x]0 who develops kidney disease. her baseline clearance c0 drops to one half of the original (½c0). what is the new steady state concentration of x? (for simplicity, assume that substance x is 100% filtered by the kidney).
