Answer:
Option B
Explanation:
Water soluble hormones associate with the G protein of cAMP. This G protein is intra-cellular i.e found inside the cell.
However in case of lipid derived hormones, the hormone has to diffuse through the cell across the plasma membrane to bind to DNA or the intra-cellular receptors.This regulates the gene transcription and induces protein production that affects the cell functioning for a long time.
Hence, option B is correct
Answer:
c. Both have their own DNA.
Explanation:
Both chloroplast and mitochondria are semi-autonomous organelles which means that they both have their own DNA. Both of these organelles have a circular DNA and make some of their own proteins by themselves. Both are double membrane-bound organelles. Chloroplast has a third membrane system called thylakoid.
Chloroplasts are found in the plant cells only as they are the site for photosynthesis. Mitochondria are present in both plant and animal cells and are the site for cellular respiration to produce energy to support the vital functions of cells.
