B) wavelength
Notice how Z goes from one wave's crest (top) to another's crest. Wavelength can also be measured from a wave's trough (bottom) to the next one's trough.
Cell is the living blocks of life. They form the structural
and the functional unit of our life, that is a group of cell
forms tissue, a group of tissue forms organ, a group of
organs form organ system and finally a group of organ
systems form a complete organism / individual.
And there are two types of cell
1/ eukaryotic cell ( consists of the plant cell and the animal
cell )
2/ prokaryotic cell (... I don't know man )
NAD+ is the abbreviated symbol for Nicotinamide Adenine Dinucleotide. It is a coenzyme present in biological systems. NAD+ is involved in the metabolism specifically in redox reactions. It accepts electrons from other molecules and become reduced.
NADH is the reduced form of NAD+. Similar to NAD+, NADH also participates in metabolic processes when reduction is necessary. When NADH reduces a compound, it gets oxidized to NAD+.
Mutualism- both species helped
Commensalism- one species helped; one species not affected
Parasitism- one species "parasite" helped; one species "host" harmed
