Answer:
Prokaryotes lack a true nucleus with well defined nuclear membrane and other membrane-bound organelles. Mitochondria are the double membrane bound organelle and hence is absent in prokaryotes. Mesosome is an extension of the cell membrane presence in the cytoplasm as infolding and serves to increases surface area and as a site for cellular respiration in prokaryotes. Histones are positively charged proteins that serve in the packaging of negatively charged eukaryotic DNA but are absent in prokaryotes.
So, the correct answer is option A.(DNA is complexed with histones).
The correct option is (D) Nucleotide variability and average heterozygosity
The higher the proportion of loci that are "fixed" in a population, the lower are that population's nucleotide variability and average heterozygosity.
<h3>
What does it indicate when a gene in a population is fixed?</h3>
- In population genetics, fixation is the transformation of a gene pool from one in which at least two alleles of a certain gene exist in a given population to one in which only one allele persists.
- Any allele must eventually be lost entirely from the population or fixed (permanently established at 100% frequency in the population) in the absence of mutation or the heterozygote advantage.
- Selection coefficients and random variations in allelic proportions determine whether a gene will ultimately be lost or fixed. Fixation may relate to a specific nucleotide location in the DNA chain or a gene in general (locus).

Answer:
the predators and the prey that live there
Answer:
Organism
Explanation:
An individual palm tree grown in a tropical forest is regarded as an organism. This answer is gotten from the definition of an organism. An organism is defined as an individual living thing, which could be an animal, a plant, or a one celled creature. An individual palm tree is an organism because individually bit has all properties of life and can respond to stimulus.
