Answer - B
Arteries carry blood away from the heart to the rest of the body, hence they have thick walls to endure high blood pressures, whereas, capillaries have very thin walls to allow for exchange of gas and microcirculation.
cAMP is the second messenger in the pathway.
cAMP or Cyclic AMP is a secondary messenger because it transmits signals from a receptor to a target cell. When the level increases rapidly, it starts following receptor-mediated activation of AC (adenylyl cyclase), and that catalyzes the conversion of AMP (adenosine monophosphate) to cAMP.
The cAMP pathway is also known as the adenylyl cyclase pathway, which is a G protein-coupled receptor that is used in the cell signaling process. It works by activating protein kinase A. Therefore, cAMP is considered a secondary messenger which also regulates various cellular functions like cell growth, cell differentiation, etc.

Answer:
Interphase is divided into three subphases which are G1 phase, S phase and G2 phase.
Explanation:
During G1 and G2 phases, the cell grows by producing proteins and cytoplasmic organelles. Cell growth and cell differentiation occur. In the S phase, synthesis of DNA occurs. The chromosomes are duplicated and DNA has replicated to form two identical sister chromatids joined together by centromere. During interphase, the chromosomes are not visible but appear as thread-like structures, chromatin. In general. Interphase is the phase where the cell prepares for cell division. It involves synthesis of protein and organelles, growth, replication of DNA, cell differentiation and energy storage.

- It was founded by Sigmund Freud in the 19th century.
- He suggested that people can be cured of mental disorders by unlocking their unconscious experiences.
