Answer:
Symbiotic relationships are characterized by one organism feeding off of another, but both organisms benefit from the interaction. Predator-prey interactions involve one organism hunting and consuming another organism for sustenance. Both involve one organism feeding on another, but symbiotic relationships also benefit the host.

Answer: The change in the structure of the genes or change in the DNA sequence is called mutation. The mutations are of different types that are deletion, rearrangement, insertion and others.
Explanation:
Mutation in which the one to several nucleotides get changed at a point is called point mutation. The point mutation can be in the form of deletion, substitution, and insertion. Deletion will involve the removal of nucleotide that involves the change in the sequence of DNA. When the nucleotide is added to the genome it is called insertion. In deletion and insertion the whole sequence of nucleotides from the point of mutation get displaced this affect the codons in the amino acid sequence which is responsible for protein synthesis so the functioning of the body may get affected by such mutations.
In the case of substitution the new nucleotides are added to the DNA sequence and the one which was already present at that place is removed. So, only one amino acid in the sequence will change so the polypeptide structure will not be affected.
I believe it is the ascending loop of henle. In the ascending portion, the loop becomes impermeable to water and instead the cells of the loop, actively reabsorb the solute; thus water is not reabsorbed but ions are readily reabsorbed. As the ions are reabsorbed the concentration becomes more and more hypotonic until it reaches 100-150 mOsm/L. Therefore, the ascending loop is called the diluting segment of the nephron due to its ability to dilute the fluid in the loop from 1200 to 100 mOsm/L.
The light-harvesting complexes of a chloroplast are located in the thylakoid membrane.
The enzymes of the calvin cycle reactions are located in the stroma.
Chloroplast, found in plant cells and some protists such as algae and cyanobacteria, is a cell organelle known as a plastid. Chloroplasts are oval-shaped and have two membranes: an outer membrane and an inner membrane.
The enzymes required during the calvin cyle reaction are present in the stroma while, thylakoid System is the internal membrane system consisting of flattened sac-like membrane structures called thylakoids where light energy is converted into chemical energy. Thylakoids contain the light-harvesting complex, including the electron transport chains used in photosynthesis and pigments like chlorophyll and carotenoids.
