Answer:
The correct answer is option B. It bind to a receptor in the plasma membrane.
Explanation:
Hormones can be aminoacid based hormones (peptide or amine) or the steroid base hormones on the basis of their nature. Amino acid based proteins are molecules that are proteins,
Peptide hormones are the protein or peptide molecule that release in blood by the exocytosis in the form of preprohormones that mature later and bind to the receptor present on the surface of the plasma membrane of the target cell. The binding of the peptide hormone to the receptors a secondary messenger shows up in the cytoplasm.
Thus, the correct answer is option B. It binds to a receptor in the plasma membrane.
Answer:
Small leaves
Explanation:
These ensure that less water is lost from the plant by transpiration because the leaf has a smaller surface area.
I think it's A becuse the stageof meiosis is cytokinsis
Answer:
One band of light density and one band of heavy density.
Explanation:
According to conservative model of replication, the original strands do not separate from each other during replication. Hence, after replication the old strands are together and the new strands are together.
Here, cells were grown in 14N medium first so 14N was used for DNA replication and all DNA molecules had 14N. When the cells were transferred to 15N medium, only 15N was available for replication process. New DNA molecules would be synthesised using 15N (15N15N) and old DNA molecules have 14N (14N14N). Hence, in density gradient one band will be of light density (14N14N) and one band will be of heavy density (15N15N).
