A fungus with white spores cross fertilizes a fungus with black spores. If 10% of the progeny bear white spores while 90% of the progeny bear black spores, what must be true? A.

The trait for spore color is determined by exactly one gene.

B.

The trait for spore color is determined by more than one gene.

C.

The allele for black spores is dominant over that for white spores.

D.

The allele for white spores is dominant over that for black spores.

C.  The allele for black spores is dominant over that for white spores

Explanation:

Since there are more of an outcome of black spores it would make sense that this trait is dominant.

White spores seem to be recessive in this case too.

It is  also suspected that the parents are both heterozygous. They both carry one trait for black and one for white.

a neutral ph of 7 and normal organism temperature is needed for a certain enzyme to be effective.  

what would happen to the enzyme if the ph and/or temperature fluctuate greatly from the norm?  

a.the enzyme’s hydrogen bonds will break.  

b.the activation energy will increase.  

c.more product will be formed.

d.the ideal temperature and ph for the enzyme function will decrease.  

the answer is trees if i'm not mistaken
