62 -- The roots absorb water for the plant, and also provide it with stability, ie to keep it from falling over.64 -- Structure B is a leaf, and a leaf's main function is to take in sunlight and perform photosynthesis, which makes food for the plant.
Answer:
1. 1/2
2. 1/2
3. 1/4
Explanation:
Let the allele for freckles be A or a while that of dimples be B or b.
A person without freckles but heterozygous for dimples = aaBb
A person who has freckles (whose mother has no freckles) but no dimples = Aabb
aaBb x Aabb
Offspring
4 AaBb - freckled and dimpled
4 Aabb - freckled and non dimpled
4 aaBb - non freckled and dimpled
4 aabb - non freckled and non dimpled
1. <em>Probability that the parents will have a dimpled child</em> = 8/16 or 1/2
2. <em>Probability that they will have a child with freckles</em> = 8/16 or 1/2
3. <em>Probability that they will have a child with freckles and dimples</em> = 4/16 or 1/4

Answer:
All living organisms need energy to stay alive, but only producers can directly convert energy into food.
Explanation:
The process of photosynthesis is very important because all living organisms need energy to stay alive, but only producers can directly convert energy into food.
Photosynthesis is the process whereby green plants manufacture their food in the presence of carbon dioxide and water.
- They take light energy from the sun and produce food materials.
- The light energy is converted to chemical energy which are stored in carbon chains as glucose.
- The chemical energy is then used by other living organisms for their own nourishment.
