What part of a plant cell responds to turgor pressure? *
Answers
Answer:
Cell wall. The plant cell wall accounts for the turgidity and the rigidity in plants. The cell wall protects the plant cell from bursting due to the influx of water. Rather than bursting, the cell is able to withstand the osmotic pressure exerted by the water molecules.
In creating recombinant DNA, some restriction enzymes produce ______ ends in both the source DNA and plasmid DNA, and these ends can stick to each other by ______.
Answers
Answer: Single-stranded; complementary base pairing
Explanation:
Restriction enzymes are essential components of recombinant DNA technology because they can be extracted from bacterial cells and utilized in the lab to modify DNA fragments, including those that contain genes (genetic engineering).
What recombinant DNA produce by restriction enzymes?An isolated bacterial protein called a restriction enzyme breaks DNA at specific sequence-specific locations to produce DNA fragments with a known sequence at each end.
For several laboratory techniques, such as genetic engineering and recombinant DNA technologies, restriction enzymes are essential.
Therefore, In creating recombinant DNA, some restriction enzymes produce Single-stranded ends in both the source DNA and plasmid DNA, and these ends can stick to each other by complementary base pairing.

The comparison between the number of human genes and those of other animal species has led to many conclusions, including that _____.
Answers
Answer:
We have a lot of similar genes to those of animal kin.
Explanation:
The genes of humans and animals show more than 50% similarity and conclude the same ancestral origin.
What are genes?The gene can be described as the hereditary unit that results in the make-up of proteins for the functioning of the body.
The genes are hereditary and evolution there results in the change in the genotype and thereby phenotype with mutations.
The genes of humans and animals result in the similarity of more than m 50%. This concludes that there has been the presence of the same ancestral origin for the animal and humans.
The genetic similarity between humans and the animal species results in the conclusion of humans belong to the animal kingdom and have the same ancestral origin.

how will you explain the importance of it in completeness of the biological organization?
Answers
The importance of biological organization is that it allows the study of natural balance between all organisms in a simple way.
The biological organization is a biological term that refers to the hierarchy of complex biological structures and systems that define life through a reductionist approach.
In this form of organization, the traditional hierarchy begins in the atom, this being the lowest level, and ends in the biosphere as a superior system.
The integrality of this organization focuses on the reciprocal relationships between each level, because the higher levels are more complex, but contain each of the organisms and parts that make up the lower levels. This type of organization must be understood as a whole.
