Question b) "66%".
Explanation:
Achondroplasia is caused by a dominant allele, which means that a person with a "A" allele will develop this condition. In this case, all the people with Achondroplasia are heterozygotes "Aa" because the dominant genotype "AA" causes prenatal death. If a person with achondroplasia "Aa" mates with a person of average height "aa", the expected percentage of children with average height will be 50%, since there are 50% of chances of having "aa" children and 50% chances of having "Aa" children. Also, If two persons with achondroplasia have children ("Aa" x "Aa") , the expected percentage of children with achondroplasia will be 66%. The probability of having children with the "Aa" genotype is 50%, however since the "AA" genotype causes prenatal death, this genotype is not considered in the percentage.
Answer:
The answer is A.
Explanation:
The permeability of the pacemaker cell's membrane is the factor that controls the density of the materials inside the cell which also includes sodium and that controls the neurons and muscles. So if we were able to artificially alter the pacemaker cell's membrane parmeability, for the heart it would result in a quicker satisfaction of the threshold value and therefore would increase the heart rate.
