Let’s assume that dragons show incomplete dominance for fire breathing. The F allele provides lots of fire and the F’ allele giv
laila [671]

The progenies of the dragons with strong fire and dragon with no fire will be dragons with fire at medium rate.

<h3><u>Explanation:</u></h3>

Incomplete dominance is the phenomenon when two different alleles are present in a same organism gives a mixed type of phenotype which isn't similar to any characters of the parents.

In case of the dragons, the genotype of the dragons with strong fire = FF.

The genotype of the dragons with no fire = F'F'.

So the gametes produced by the dragon with strong fire is F and that by the dragons with no fire is F'.

So the dragons produced as a progeny = FF'.

As this gene shows incomplete dominance, so both the characters will be mixed and present as a mixed character. So the offsprings will be moderately fire breathing.

Which of the following does not describe enzymes?
Oksanka [162]

The statement 'enzymes work by raising the energy of activation' is NOT true about the enzymatic activity. These proteins lower this energy.

<h3>Enzymes and activation energy</h3>

Enzymes are proteins capable of catalyzing specific chemical reactions in a given medium.

Enzymes work by lowering (instead of increasing) the activation energy of a chemical reaction.

Enzymes help to convert one or more reactants into specific products of the reaction that they catalyze.
