Answer:
I and II
Explanation:
I. irrigation of cropland & II. harvest of biomass for energy
Answer: NADPH and ATP
Explanation:
The mechanism of photosynthesis can be divided into two phases, light reaction, and carbon fixation. During the light reaction, photosynthetic pigments absorb radiant energy and undergo a series of photochemical reactions and convert the trapped energy into chemical energy which is stored in the form of NADPH and ATP. These two compounds constitute the assimilatory power. Light reaction is light dependent and it takes place in the grana of the chloroplast.
Answer:Atoms of nonmetals have a tendency to gain or share electrons when they react.
Explanation: Non-metals are elements that gain electron to form negatively charged ions known as anions.
When non-metals react, they either gain/accept electron from a metal atom or share electron with another non-metal atom. When a non-metal accepts an electron from a metal atom, the type of bond formed is called ionic or electrovalent bond. In electrovalent bond, the metal atom transfers its valence electrons to the non-metal atom so that both attain a stable octet or duplet structure.
When a non-metal shares electron with another non-metal atom, the type of bond formed is known as covalent bond. In covalent bond, the two non-metal atoms share a pair of electron, each atom donating one electron to form a pair.
