Answer:
The correct answer is option B, that is, phthalates.
Explanation:
A class of chemicals that are used to soften plastics like PVC, function as fixatives and solvents and bind fragrances in the products are known as phthalates. The human encountering with the chemicals can take place via:
1. Inhalation of fragrances or fumes from fixatives and solvents,
2. Chewing on a plastic toy by a child that develops small openings in the plastic, which provides a space for the chemical to get leached from the toy into the mouth of the child.
3. Through the absorption of perfumes, lotion, and deodorants.
The serious health effects of the chemicals comprise developmental and reproductive issues, hormone disruption, low sperm count, asthma, undescended testes, preterm birth, premature puberty, and development of certain kinds of cancers.

Complete question:
If the recessive allele for cystic fibrosis is represented as c, classify the following genotypes as homozygous dominant, homozygous recessive, or carriers: CC,Cc, and cc. State which one has the phenotype of cystic fibrosis.
Answer:
CC - homozygous dominant
cc - homozygous recessive
Cc - carriers
cc will have the phenotype
Explanation:
Cystic fibrosis is an autosomal recessive disorder that affects the production of mucus in the body, primarily affecting the lungs and digestive system.
Because it is autosomal recessive, an affected individual needs to inherit 2 copies of the faulty gene. The presence of just one normal copy of the gene is sufficient not to cause the disease
In genetics, the dominant allele is usually displayed as a capital letter and the recessive as a small letter. Homozygous means someone has 2 copies of the same allele, heterozygous means they have different alleles. Therefore, CC - homozygous dominant, cc - homozygous recessive, and Cc - carriers. Only those with a cc genotype will be affected, as the presence of one dominant allele is enough to block the phenotype
Answer:
The probability that both will be Rh-negative out of 99% Rh-positive is 0.01 x 0.01 = 0.0001.
Explanation:
The population contain 99℅ of Rh-positive. This represent almost all of the people.
However, there is still 1℅ chance of having an individual of Rh-negative.
Both of them will have the probability of 1℅ of having Rh-negative(0.01).
Therefore, Pr(Rh-negative AND Rh-negative) = 0.01 x 0.01. The result is approximately equals zero.
The both parents having Rh-negative, will have a dominant Rh-negative blood passed to their children, only recessive Rh-positive of 25℅ chance.
Since the chance of Rh-negative blood passed to their children is 75℅, it is inevitable that their children will be Rh-negative
