Answer:
b. A + G = C + T
Explanation:
Chargaff's rule states that<em> </em><u>a DNA molecule has the same amount of pyrimidines (T and C) as purines (A and G)</u>.
In the DNA, A pairs with T and G pairs with C. For that reason, the number of A bases has to be the same as the number of T bases, and the number of G has to be the same as the number of C.
The cell cycle is important because without it we wouldn’t get new cells
for growth and repair. Humans would not survive without the cell cycle.
Interphase has the cells carry out the functions that are needed to
survive and the cells that divide prepare for reproduction. Mitosis has
the cell’s nucleus divide. Cytokinesis is when the duplicated contents
of mitosis are made into two daughter cells. Without these three things
we would not be able to survive.
Answer:
Photosynthesis is the process by which plants make their own food in the presence of sunlight by utilizing carbon-dioxide and water and produces oxygen and energy.
The process of photosynthesis has two types of reactions: light-dependent reactions and light-independent reactions.
The light-dependent reactions occur in the thylakoid membranes of chloroplasts in which plants use light energy to form ATP and the reduced electron carrier NADPH.
In this reaction, photosystem II (P700) absorbs lights energy and passed it to reaction center. this energy is then is transferred to photosystem I (P680), that pump an electron to a high energy level. The high-energy electron then travel to an electron transport chain and releases energy. this released energy pump H+ ions into the thylakoid interior from the stroma and build a gradient H+ ions move through gradient and they pass through ATP synthase resulting in the formation of ATP.
The higher energy electron as moves into an electron transport chain, the electron is passed to NADP+ to form NADPH.
I believe it is dissecting
The substance, DDT, damages a bird life until it was largely ban in the 1970s. DDT (<span>dichlorodiphenyltrichloroethane) is a colorless, tasteless, odorless, and crystalline organochloride known for its insecticide properties.</span>
