A scientist investigated DNA replication in two groups of cells, labeled A and B. She injected radioactively labeled nucleotides

into cells of each group and allowed DNA replication to begin. When replication was halfway completed, she injected a drug into the cells to stop replication. She then examined the cells to determine the distribution of the newly-synthesized DNA. She found each cell of group A had many segments of new DNA in its nucleus, while each cell of group B had a single segment of new DNA in its cytoplasm.
What can the researcher conclude about the cells?

A.
Group A cells are prokaryotic because they must have many origins of replication.
B.
The cells in group B are prokaryotic because they replicate their DNA in the cytoplasm.
C.
Group B cells are eukaryotic because they must have a single origin of replication.
D.
The cells in group A are eukaryotic because they replicate their DNA in the cytoplasm or nucleus.

According to carl rogers, the ________ is how people see their actual traits and abilities.
masha68 [24]

According to Carl Rogers, the <u>real self</u> is how people see their actual traits and abilities.

  • The Real Self and the Ideal Self make up the personality, according to humanistic psychologist Carl Rogers.
  • They are words that are used to characterize a person's personality facets. The true talents, aptitudes, preferences, and attributes of an individual are reflected in one's real self.
  • The ideal self and the real self were further split by Rogers into two groups.
  • The difference between your real self and your ideal self is that the latter is the person you truly are. Rogers emphasized the requirement for consistency between these two selves.
  • For example, your ideal self might be someone who spends a lot of time learning, does well in science topics, and is not sickened by the sight of blood. If your Real Self differs significantly from this idealized version, you may feel unsatisfied with your life and like a failure.

Mitochondrial DNA accumulates DNA mutations quickly. Because of this, it would be most beneficial in analyzing the ancestral rel
konstantin123 [22]
The answer would be: <span>A. Mitochondrial DNA is beneficial in both of these cases
</span>
Mitochondrial DNA or mtDNA is DNA that found in the mitochondrial. Mitochondrial DNA only inherited from mother, so it's relatively unchanged than nuclear DNA that mixed from father and mother. 
Mitochondrial DNA has higher mutation rate in animals because it doesn't have repair mechanism like nuclear DNA. These mutations can be used as a clue for how close the relation of an organism to others.
This makes analyzing the ancestral relationship of organisms that closely or distantly related easier.
