Answer:
A rock is a collection of minerals. In a cooling lava, mineral crystals do not have time to form and are very small. The chemical composition will be the same as if the magma cooled slowly. Existing rocks may be heated enough so that the molecules are released from their structure and can move around.
Explanation:
After the adenylyl cyclase reaction (which convert ATP into cyclic adenosine monophosphate-cAMP), cAMP level is directly increased. Next steps of PKA activation include:
• cAMP binding to regulatory subunits of PKA, as a result conformational change in the regulatory subunits of PKA is induced,
• catalytic subunits are detached and unleashed by regulatory subunits and as a result activated.
Light energy (from the sun) is used to convert carbon dioxide and water into glucose and oxygen in the process of photosynthesis.
carbon dioxide + water --> glucose + oxygen
the light energy from the sun is then trapped in the glucose. in order to retrieve the chemical energy stores within the molecule, the bonds have to be broken.
Endocrine glands secrete hornmones whereas
exocrine glands secrete enzymes....
here, Pituitary gland secrete stimulating and growth hormone and thyroid gland secrete thyroxine hormone whereas salivary gland produce enzyme called saliva
So,pituitary gland and thyroid gland are endocrine and salivary glands are exocrine...
