Buildup of organisms means that the species number is pretty high.
Gradual change means that it was a slow, calm time to make the change.
I hope this helps!!
The greatest degree of genetic variation would be found in an offspring resulting from sexual reproduction.
<u>Explanation:</u>
Asexual reproduction produces very less variations. Asexual reproduction requires only one parent and thus the offspring would be very similar to the parent. The chance of variations in offspring is very less.
But the case of sexual reproduction is different. Sexual reproduction involved two parents and each parent contribute equal amount of genetic material to the progeny.
Some characters of the offspring will be like one or the other parent and some characters will be a combination of the characters of both parents
. Such a combination produces variant offspring.
Protozoa are Eukaryotic organisms, they show animal/plant like behaviors. Bacteria are prokaryotic, very tiny simple single celled organisms with no nucleus or mitochondria.
Chromosomes are made up of two sister chromatids , and are then dispersed as chromatin which is the DNA making up the chromosome.
Antophytes attract pollinators through sweet nectar and/or fruits. They are a type of plant that bears flower-like structures that secrete distinct scents that attract organisms and help them thrive and get pollinated more. These flowers would then grow and mature into fruits that can be attractive to bigger organisms.
