Answer:

a) It is dangerous to wear nylon clothes while cooking because it is a synthetic cloth and they catch fire easily also they can stick on our body which is very painful.

b) Cotton is a natural product. And unlike synthetic fibres, it is more absorbent. The towel hence has high absorbency.

c) Nylon and polyester are two fabrics most commonly used in raincoats and umbrellas. They are not absorbent the way natural fibers are. They naturally resist waterlogging, and can be made waterproof.

1 is C - see first attachment. Genotypes with Y's represent males, and big R represents red eyes, while little r represents white eyes. For example XRxr is a heterozygous (red-eyed) female, and XrYr is a homozygous white-eyed male.

2 is B because the absence of functional proteins and some ribosomes due to the mRNA strand is not as detrimental as the loss of the entire cell.

3 is B. (The insertion of 3 base pairs into a genetic sequence is the length of a single codon, meaning that only one amino acid in the entire polypeptide was added)

Fill in the Punnett square below to visualize the offspring of a cystic fibrosis carrier and a person who doesn't have cystic fi
valkas [14]

Answer:

50% of their children are likely to be carriers of cystic fibrosis

Explanation:

Since the normal allele "F" will be the dominant allele while the mutated CFR allele "f" will be the recessive allele, <u>the gene (pair of alleles) of the person that is a CFR carrier will be "Ff" while that of the normal person who isn't a carrier will be "FF"</u>. The attachment shows the crossing between the two parents. From the illustration in the attachment, for every 4 children given birth to, 2 of them will likely be normal, "FF", (not a carrier and doesn't have cystic fibrosis) while 2 others will likely be carriers of cystic fibrosis (Ff). Hence, 50% of their children are likely to be carriers of cystic fibrosis.
