Helper T cells become activated by interacting with antigen presenting cells. and the second blank space is either cytotoxic t cells or B cells
I believe the correct answer is the second option. Maltose and water would be formed from the reaction of two glucose molecules. This reaction is called the dehydration synthesis reaction. The production of water signifies that it is a dehydration reaction. It is a reaction which involves putting together two molecules while losing water molecules. Polymers can be formed from this type of reaction. Some polymers are complex carbohydrates, proteins and nucleic acids. It is also considered as a condensation reaction because two molecules are being condensed into a larger molecule and losing a small molecule which is the water.
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
DNA has thymine and RNA has uracil both of which pair with adenine.
Hope that helps.
