Answer:
3.5%
Explanation:
The genes crossveinless and Stubble are linked and 7mu apart. That means that the frequency of recombination between them during meiosis will be 7%.
The alleles for crossveinless are:
- cv-c+ wildtype, dominant
- cv-c mutation, recessive
The alleles for Stubble are:
- Sb mutant, dominant
- Sb+ wildtype, recessive
A dihybrid female Drosophila with genotype cv-c Sb+/cv-c+Sb is testcrossed (crossed with a homozygous recessive male):
cv-c Sb+/cv-c+Sb X cv-c Sb+/ cv-c Sb+
<u>The male can only produce one type of gametes:</u> cv-c Sb+
<u>The female can produce 4 types of gametes:</u>
- cv-c Sb+ Parental, 46.5%
- cv-c+Sb Parental, 46.5%
- cv-c Sb Recombinant, 3.5%
- cv-c+Sb+ Recombinant, 3.5%
The frequency of recombination between cv-c and Sb is 7%, and 2 recombinant gametes are formed, so each of them will appear 3.5% of the times. The parental gametes will have a frequency of 100%-7%=93%, and there are 2 of them so each will have a frequency of 46.5%.
Only when the recombinant gamete cv-c+Sb+ joins the gamete generated by the male parent will the offspring be wild-type for both genes, so the proportion of phenotypically wild-type individuals in the progeny will be 3.5%.
Answer: C) insoluble fiber
Explanation:
The statement that best describes the use of a catalyst in a fuel cell is : ( D ) It increases reaction rate
A catalyst in a fuel cell speeds up/facilitates the rate of reaction of oxygen and hydrogen especially at the oxygen electrode of the fuel cell.
Generally catalyst is any substance that increases the rate of a chemical reaction without been used up in the process, while lowering the activation energy required to kickoff the reaction.
Hence we can conclude that the statement that best describes the use of a catalyst is that it increases the reaction rate

I would say C because our body is continuously changing through puberty. We need more sleep, more food consumption, we need to have fantastic hygiene, etc...
Larynx is the correct answer.
