Answer:
Continuous variations are formed due to chance segregation of genes during gamete formation, crossing over and chance combination during fertilization. They can increase adaptability of the race but cannot form new species.
Meiosis produce cells with half the chromosomes, because a<span> gamete needs only half the number of chromosomes, because two gametes join together. </span>
The correct answer is - Most killer whales congregate in the areas that are near the Arctic/Antarctic Circles.
The killer whales have a very large distribution, and they can be found in all oceans, apart from the Southern Ocean. It is noted though that the population density of the killer whales differs from place to place. The higher concentrations are found around the Arctic and Antarctic Circles, where there's cool rich waters, while in the lower latitudes they are much rarer. The reason for this probably lies in the fact that most of the animals that are considered to be the prime food source of the killer whales are living in this rich cold waters.
Answer:
<u>50%</u>
Explanation:
<em>Since</em> it was not a case of a Lettuce seed exposed first to <em>red light</em> and then to <em>far-red light</em> which will very likely not germinate because Pr (chromoprotein inactive form) absorbs red light efficiently, the light absorbed will convert a high proportion of the molecules to the Pfr (chromoprotein active form), thereby inducing germination. So there is a 50/50 percentage chance of of germination.
Gram-positive microorganisms have a thicker layer of peptidoglycan which traps a greater amount of the gem violet included and upon de-colorizer discharges approximately caught stains.
Gram-positive cell dividers contain a thick peptidoglycan layer with teichoic acids. Gram-negative cell dividers contain a thin peptidoglycan layer that is encompassed by a thick plasma film. Gram-positive microorganisms will recolor purple in view of their thick peptidoglycan cell divider.
