OH- and H+ , and let's not forget H3O^+
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.
Agree
Explanation:
It is very correct that plants cannot walk and animals can't use energy from the sun.
Locomotion is the movement of body from one place to another.
The process by which plants manufacture their food using sunlight is called photosynthesis.

Epigenetics is the study of how the structure and function of genes interact with our environment to influence behavior.
In addition to your surroundings and habits, such as what you eat and how much exercise you get, your genes play a significant part in determining your health. The field of epigenetics investigates how environmental factors and behavior may alter how your genes function. Gene-environment interactions that result in the expression of different phenotypes throughout development are the basis for the initial usage of the term "epigenetics." To turn on or off the genes that cause long-lasting alterations linked to the differentiation of various cell types, epigenetic processes are frequently used.
Epigenetics is the study of how DNA sequences are maintained as genes are controlled by cells. DNA alterations known as epigenetic changes control whether or not genes are activated.
