Answer:
See the answer below
Explanation:
Let the disorder be represented by the allele a.
Since the disease is an autosomal recessive one, affected individuals will have the genotype aa and normal individuals will have the genotype Aa or AA.
Since the four adults are carriers, their genotypes would be Aa.
Aa x Aa
Progeny: AA 2Aa aa
Probability of being affected = 1/4
Probability of being a carrier = 1/2
Probability of not being affected = 3/4
(a) The chance that the child second child of Mary and Frank will have alkaptonuria = 1/2
(b) The chance that the third child of Sara and James will be free of the condition = 3/4
(c)
(d) If someone has no family history of the disorder, their genotype would be AA.
AA x aa
4 Aa
<em>The chance that a child with alkaptonuria will have an offspring with alkaptonuria if the child's mate has no family history </em>= 0
(e)
(f) <em>The chance that a child with alkaptonuria will have an offspring with alkaptonuria if the child's mate has no family history</em> = 0
The correct answer is that "xylem transports water, stomata take in carbon dioxide, and chlorophyll absorbs sunlight." The xylem is a vascular structure in plants that transport water, the phloem is another vascular structure in plants that transport nutrients. The stomata (singular; stoma) is the one responsible for the plants' gas exchange (takes in carbon dioxide, releases oxygen). The chlorophyll is what makes the green pigment of the leaves and mostly because of the presence of chloroplasts, the organelle in plant cells responsible for photosynthesis.
30 minutes of physical activity every day, Im pretty sure
