Answer:
One choice should be “exponential growth curve”, choose that. If you could post a pic of the remaining options, I'll try and solve it for you further.
Answer:
a dominant mutation
Explanation:
A monohybrid testcross is a cross-breeding experiment used to determine if an individual exhibiting a dominant phenotype is homo-zygous dominant or heterozygous for a particular phenotypic trait (in this case, wing length). In a monohybrid testcross, a 1:1 phenotypic ratio shows that the dominant parental phenotype was a heterozygote for a single gene that has complete dominance. Moreover, a 3:1 ratio in the F2 is expected of a cross between heterozygous F1 individuals, which means that 75% of individuals with short wings have the dominant allele that masks the expression of the long-wing trait (i.e. the recessive allele).
Respiration is done aerobically, using oxygen. a similar process is fermentation, yet it is done anaerobically, without oxygen. Fermentation, as a bi product, produces ethyl alcohol.
