Answer:
True.
Explanation:
Enkephalins and endorphins are endogenous peptides while morphine is an exogenous peptide.
Enkephalins and endorphins are powerful analgesics 18 to 500 times more than morphine. Hence, morphine is less analgesic than enkephalins and endorphins.
Enkephalins and endorphins act on the mu, kappa , delta receptors and morphine also acts on the same receptors. All of them has same effects on the body.
Hence, Enkephalins and endorphins are peptides that act like morphine.
<em>G1, S and G2 phases are all cumulatively referred to as interphase involving the growth of a cell and the replication of its DNA. Initially in G1 phase, the cell grows physically and increases the volume of both protein and organelles. In S phase, the cell copies its DNA to produce two sister chromatids and replicates its nucleosomes. Finally, G2 phase involves further cell growth and organisation of cellular contents. The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells. The S phase only begins when the cell has passed the G1 checkpoint and has grown enough to contain double the DNA. S phase is halted by a protein called p16 until this happens.</em>

Answer:
Whale shark
Explanation:
The world's largest fish is the whale shark, which can grow to 40 feet long and weigh an average of 20 tons. The sharks are carnivorous, but they aren't likely to take a nibble out of an unwary surfer – they filter plankton through their enormous mouths while swimming at the surface
