When exposed to bright sunlight, some people involuntarily sneeze. This reaction is known as a photic response. It is controlled

by a single gene with two alleles, H and h.A man and a woman who sneeze when exposed to bright sunlight are both heterozygous for the photic response trait.
Identify the most likely inheritance pattern for this trait (dominant-recessive, codominant, sex-linked, or polygenic).

Answer:

dominant-recessive

Explanation:

Photic sneeze reflex is an autosomal dominant or dominant-recessive disorder that means that person having only a single dominant allele of the gene of trait will suffer from the disorder irrespective of the sex.

As mentioned in the question, the Photic sneeze reflex disorder is a condition in which a person, when exposed to bright sunlight,involuntarily sneeze.

Since the disorder is autosomal dominant, it means that A man and a woman who sneeze when exposed to bright sunlight can both be heterozygous for the photic response trait. Therefore, if one of the if one parents is affected, there are 50% chances that the child will inherit syndrome and be effected.

If you want to better understand the pattern of autosomal dominant or dominant-recessive disorders, please see attached image.

Hope it helps!

Akimi4 [234]

Answer:

The correct option is B. Fermentation would occur at a similar rate to that of glucose.

Explanation:

Fermentation can be described as a process in which alcohol is released by using sugars. In fruit juices, fructose is present mainly to get the sweetness. It is used as a substitute for glucose because fructose is more sweeter than glucose. Both fructose and glucose are monosaccharides with the formula C6H12O6. The only difference is in the arrangement of molecules in the atoms of these compounds. Hence, the rate of fermentation would be same for these two sugars.

A hypothetical three-step metabolic pathway consists of the intermediates W, X, Y, and Z, and the enzymes that catalyze the reac
GenaCL600 [577]

Answer:

ZBWCYAX

Explanation:

Equation for the intermediates: Z↔W↔Y↔X

1) B catalyzes the breakdown of Z, therefore inhibiting B leads to the build up of Z.

2) If enzyme C is inactive then the organism will not  receive Y to grow, thus Y is a by-product of C.

3) If A is inhibited then W, Y and Z build except for X, thus it make sense that A catalyzes a reaction that leads to X as a by-product.

4) Inhibiting C leads to the reaction toward making Z and W, thus it catalyzes the breakdown of C directly and Z indirectly.
