Answer:
0.0177
Explanation:
Cystic fibrosis is an autosomal recessive disease, thereby an individual must have both copies of the CFTR mutant alleles to have this disease. The Hardy-Weinberg equilibrium states that p² + 2pq + q² = 1, where p² represents the frequency of the homo-zygous dominant genotype (normal phenotype), q² represents the frequency of the homo-zygous recessive genotype (cystic fibrosis phenotype), and 2pq represents the frequency of the heterozygous genotype (individuals that carry one copy of the CFTR mutant allele). Moreover, under Hardy-Weinberg equilibrium, the sum of the dominant 'p' allele frequency and the recessive 'q' allele frequency is equal to 1. In this case, we can observe that the frequency of the homo-zygous recessive condition for cystic fibrosis (q²) is 1/3200. In consequence, the frequency of the recessive allele for cystic fibrosis can be calculated as follows:
1/3200 = q² (have two CFTR mutant alleles) >>
q = √ (1/3200) = 1/56.57 >>
- Frequency of the CFTR allele q = 1/56.57 = 0.0177
- Frequency of the dominant 'normal' allele p = 1 - q = 1 - 0.0177 = 0.9823
Explanation:
science is the practical and intellectual activity encompassing the systematic studying of the behaviour and structures of the physical and natural world
Activation energy is required to start a chemical reaction. Activation energy is the energy needed to allow the reactant to react. Activation energy is measured in Joules (J).
Answer:
a.) ventilation, circulation, cellular respiration
Explanation:
a.) ventilation, circulation, cellular respiration
b.) diffusion in tissues, cellular respiration, diffusion at respiratory surface
c.) ventilation, diffusion in tissues, circulation
d.) circulation, cellular respiration, diffusion in tissues
e.) circulation, ventilation, cellular respiration
Ventilation occurs in the lungs and is the process by which carbon dioxide in the capillaries is lost to the environment while oxygen is taken in. Circulation is the process by which this dissolved oxygen is taken by the blood to tissues around the body. When this oxygen is taken to tissue, the concentration gradient allows the oxygen to be taken up by tissue. This oxygen is used as an electron acceptor (when it reduced to water) in the mitochondria during electron transport chain of cellular respiration.
Answer:
The ovary often supports a long style, topped by a stigma. The mature ovary is a fruit, and the mature ovule is a seed. Stigma: The part of the pistil where pollen germinates
