Organisms are classified as eukaryotes or prokaryotes based on their basic body structure. Which of the following is true of org
Len [333]

Question 9: The right answer is B (the second one)

The two major types of cellular, prokaryotic and eukaryotic organisms.

* Prokaryotes are identified with bacteria: most live as single-cell organisms but some bacteria associate in a chain. Prokaryotes have their DNA in the cytoplasm of the cell.

* Eukaryotes have a nucleus, a compartment separated from the rest of the cellular contents, which contains the DNA.

Question 17: The right answer is incomplete dominance.

Incomplete-dominated genetic action is a type of genetic action where one of the alleles outweighs the other in the production of qualitative phenotypes, without the dominant allele completely overshadowing the heterozygous recessive allele. Two copies of the dominant allele are required to produce the dominant phenotype. Since the recessive allele can perform its function at the heterozygous stage, this genotype produces a phenotype (the heterozygous phenotype) which differs little from the dominant phenotype.

In our case the phenomenon of incomplete dominance gave a pink color (between white and crimson) instead of crimson color when the white flowering plant was mixed with the crimson flower plant.

Question 19: The right answer is Speciation occurs gradually.

Speciation is a term that means the formation of new species.

Gradualism is an evolutionary theory according to which new species occur by gradual transformation of ancestral species, by evolution.

These transformations are slow and regular. Otherwise expressed: evolutionary theory according to which speciation is gradually effected by small successive changes over long periods.
