Answer:
The conformational change in the G protein coupled receptor.
Explanation:
GPCR or the G protein-coupled receptor is one of the largest group of receptors in the eukaryotes.
The GPCR are seven-transmembrane receptors which are attached to the G proteins. The binding of the stimulus signalling molecules to the GPCR causes a conformation change in the GPCR. This conformational change in the GPCR disrupts the interaction between the G proteins and GPCR.
The change in the conformation of the receptor causes the dissociation of the G proteins and which can interact with other molecules of the membrane.
Thus, the conformation changes in the GPCR are the correct answer.
The production of sperm and egg cells are an indication that meiosis took place in the life cycle of a jellyfish. Gametes, or sex cells are produced in meiosis. Another indication is based on the legend in the phase 1 arrow, is haploid. The result of meiosis is also haploid, while in mitosis it is diploid.
Answer:
Both have two circuits for circulation.
Explanation:
- The two circuits of circulations are known as the systemic circuit and the pulmonary circuit.
- In the<u> systemic circuit</u> oxygenated blood from the heart is pumped to all parts of the body through the blood vessels and then the blood is pumped back to he heart.
- In the<u> pulmonary circuit</u> deoxygenated blood from all parts of the body is pumped from the heart to the lungs to be oxygenated and after it is oxygenated it is pumped back to the heart.
