sergejj [24]

Answer:

1. Sickle cell anemia is an inherited red blood cell disorder in which there aren't enough healthy red blood cells to carry oxygen throughout your body. Normally, the flexible, round red blood cells move easily through blood vessels. In sickle cell anemia, the red blood are shaped like sickles or crescent moons.

Symptoms: Pain

2. Diabetes is the <u>condition in which the body does not properly process food for use as energy</u>. Most of the food we eat is turned into glucose, or sugar, for our bodies to use for energy. The pancreas, an organ that lies near the stomach, makes a hormone called insulin to help glucose get into the cells of our bodies.

3. Acne is a skin condition that occurs when your hair follicles become plugged with oil and dead skin cells. It causes whiteheads, blackheads or pimples. Acne is most common among teenagers, though it affects people of all ages.

Assume that plant weight is determined by a pair of alleles at each of two independently assorting loci (A and a, B and b) that
shepuryov [24]

Answer:

10g

Explanation:

A cross between genotype AA BB is crossed with a plant with genotype aa bb will produce

Parent genotype:AABB x aabb

Gametes: AB x ab

F1 generation - AaBb

Since an uppercase letter contributes 4 g to weight and each allele represented by a lowercase letter contributes 1 g to weight.

Thus, 4+1 + 4 + 1 = 10g
