Which pair of terms are missing from a and b on the diagram?

a, chlorophyll; b, atp

a, chlorophyll; b, water

a, nadph ; b, sunlight

a, oxygen; b, atp

The correct answer is "A, chlorophyll; B, ATP".

Explanation:

Light-dependent reactions are a series of chemical conversions that take place during photosynthesis in plants. These reactions occur in chloroplasts, particularly at the green pigment chlorophyll. Light-dependent reactions require sunlight and water, and at the end two molecules are produced: NADPH and ATP, while oxygen is produced as a byproduct.

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.

thrombocytopenia, which is a deficiency in blood platelets, can cause bleeding and bruising in the dermis similar to senile purpura. other possible causes include: exposure to ultraviolet rays and aging skin are common causes of senile purpura. senile purpura may also be a sign of collagen loss in the skin and bones.
