The majority of carbon dioxide in the blood is transported by (Option C.) conversion to bicarbonate. Which is generated through a reaction between carbon dioxide and water.
Transport of Carbon Dioxide in the BloodstreamThe majority of carbon dioxide in the blood is transported by conversion to bicarbonate. This conversion of carbon dioxide to bicarbonate is catalyzed by carbonic anhydrase, an enzyme found in the red blood cells. Through this reaction, carbon dioxide combines with water to form carbonic acid, which is then broken down into bicarbonate and hydrogen ions.
The hydrogen ions are then released into the bloodstream, while the bicarbonate is used to buffer the pH of the blood. The bicarbonate is then transported to the lungs, where it is released in exchange for oxygen and carbon dioxide.

(Do the parental Punnett square and remember they DON’T have the disease,) c)Using the probability from part b, what is the chance that, if they are both carriers, their child will have the disease?
Cystic fibrosis is only expressed by individuals who have two copies of the mutated recessive allele. A) the genotypes of both Sara and Daniel’s parents is heterozygous Cc. B) the probability that Sara and Daniel are carriers is 50%. C) Assuming Sara and Daniel are carriers, they have 25% chances of having an affected children.
What is Cystic fibrosis?
Cystic fibrosis is an autosomal affection caused by the recessive allele of a diallelic gene.
Most people have two copies of the normal allele and produce the functional CFTR protein form. Patients with cystic fibrosis have two copies of the mutated recessive allele and so produce the mutated and dysfunctional form for this protein. Heterozygote people possess only one normal CFTR allele and a mutated form for the same allele and produce a normal protein and a mutated protein.The normal allele produces enough functional CFTR protein, so these individuals do not have any adverse effect and the mutated allele is recessive at a physiological level.
In the exposed example,
Sara and Daniel express the normal phenotypeSara and Daniel's parents express the normal phenotypeSara and Daniel's siblings have the disease ⇒ they are homozygous recessive fro the trait.To answer the question, we will call C to the normal allele and c to the mutated allele.
a) What are the genotypes of both Sara and Daniel’s parents?
Knowing Sara and Daniel have siblings with the disease, we can assume their normal parents are heterozygous for the trait and each of the transmitted a recessive allele to that sibling. This is the only way these individuals could express the affection.
The genotype of Sara and Daniel’s parents is Cc.
b) What is the probability that Sara and Daniel are carriers for the disease?
Assuming their parents are heterozygous for the trait, the probabilities of being carriers (Cc) are 50% for each of them.
This is because when crossing two heterozygous individuals, the proportions among the progeny are 25% homozygous dominant, 50% heterozygous (carriers) and 25% homozygous recessive.
Parentals) Cc x Cc
Gametes) C c C c
Punnett square) C c

c Cc cc
F1) 25% of the progeny is expected to be CC, expressing the normal phenotype.

25% of the progeny is expected to be cc, expressing cystic fibrosis.
c) Using the probability from part b, what is the chance that, if they are both carriers, their child will have the disease?
Assuming both parents are heterozygous, each of them has 50% chances of transmitting the recessive allele to their progeny.

Which of the following statements regarding natural selection is false?

What is natural selection?
Natural selection is the variation in individual survival and procreation brought on by phenotypic variances. The evolution of a population's heritable features across generations is a fundamental mechanism of evolution. The term "natural selection" was popularized by Charles Darwin, who contrasted it with artificial selection, which, in his opinion, is intentional whereas natural selection is not.At the expense of less favorable variants, those genotypic variations (the full complex of genes inherited from both parents) that boost an organism's chances of survival and reproduction are conserved and multiplied from generation to generation. As a result of this process, evolution frequently takes place. Natural selection can result from variations in survival, fertility, growth rate, mate-success rates, or any other part of the life cycle. Natural selection is responsible for all of these variations to the extent that they influence how many offspring an organism produces.Hence, option A is correct

in the last question, you calculated the frequency of the deleterious allele in the population. how many individuals in the village would be carriers for this disease?
The assertion indicates that 32% of the village's residents would be infected with this disease.
What are examples and alleles?For instance, the same trait, eye color, is defined by two alleles that stand for black eyes or brown eyes, etc. All of an organism's alleles together make up its genotype. If a set of alleles are similar to one another, the genotyping of an individual is known as homozygous.
Briefing:We determined the prevalence of the harmful allele in the sample for the final question.
We must now determine the approximate number of disease carriers in the village.
A healthy individual who carries a single recessive harmful gene will have minimal issue carrying the allele it onto their progeny. Even when there are many detrimental recessive alleles in a large population, they seldom show up, therefore this usually isn't a problem.
Simply dividing the total of duplicates of all the variants at that distinct genetic site in the group by the quantity of times an allele of concern is detected in a population, an allele frequencies can be calculated. Allele frequencies can be expressed as a decimal, a fraction, or a percentage.
