<h3><u>Answer;</u></h3>
Carbohydrate
<h3><u>Explanation;</u></h3>
- Carbohydrate is the macromolecule produced during photosynthesis for plant food. Carbohydrate is among the four major macromolecules, others being, nucleic acid, lipids, and proteins.
- During photosynthesis energy from the sun, together with water and carbon dioxide are used to make nutrients or organic compounds such as simple sugars like glucose.
- By using the energy from the sunlight and absorbing the water molecules from the soil, the plant produces glucose molecules. The glucose is a carbohydrate.

-The number of B cells producing the antibody is proportional to the concentration of that antibody.
-On day 16, one out of 100000 B cells are specific for antigen A
\frac{1}{100000} = 1 x 10⁻⁵ B cells
- on day 16, Antibody concentration is 2 × 10¹= 20 Antibodies
- on day 36, antibody concentration 8 × 10³.= 8000
20 antibodies ------------ 1 x 10⁻⁵ B cells
8000 antibodies--------------x
x= (8000 x 1 x 10⁻⁵)/ 20
x= 4x10⁻³ or 1 in 250 are <span>B cells specific for antigen A</span>
Answer:
Of all the energy that does reach Earth, slightly less than 34 percent is reflected back to space by clouds. The Earth itself reflects another 66 percent back to space. Less than one percent of the total energy that reaches Earth is used by plants for photosynthesis.
