What would happen to the possible variation in gametes if the number if chromosome pairs increased from two to three?
Orlov [11]
<span>If each of the pairs of chromosomes was heterozygous (what gives you the highest potential number of different gametes), then the number of possible gametes increases from 4 to 8 for a diploid organism. To figure out how many are possible, raise the number of homologous chromsomes (2 for a diploid organism) to the power of the number of chromosomes. So if you have two different chromosomes (A and B), raise 2 to the 2nd power (or multiply 2 x 2) and you have 4. If you have chromosomes A, B, and C, then you have 2^3, or 2 x 2 x 2 = 8.

To show possible combinations, AaBb gives you AB, Ab, aB, or ab. AaBbCc gives possible gametes of ABC, ABc, AbC, Abc, aBC, aBc, abC, and abc. </span>

BRAINLIESTTT ASAP!!!!
puteri [66]

When antibiotics attacks a bacteria first the growth of bacteria is stopped and the bacteria will become unable to divide and spread throughout the body via the bloodstream and aortic arteries. An antibiotics' main job is to stop the growth of bacteria and other foreign entities inside our body, such as a virus, fungal spore, parasites, and other dangerous and potentially deadly protozoa, so as to prevent the body from harm that may be fatal.

On cellular level, antibiotics chemically damage the bacteria or targeted organism's DNA and alter it in such a way that they will become unable to divide any further and thus become unable to reproduce and eventually die off as the white blood cells engulf the decaying organism's body, so it doesn't become dangerous.
