1. the breeding of two organisms that differ in a single trait monohybrid cross 2. the expression of a genetic trait; what the trait looks like phenotype 3. a phenotype (trait) resulting from homozygous genes from the offspring of true breeding purebred 4. a gene or trait that is masked when a dominant allele is present self-fertilization 5. when an organism that possesses both male and female gametes brings the two genetically identical gametes together to produce offspring recessive

The correct matching is as follows:  

1. Monohybrid cross refers to the breeding of two organisms, which vary in just a single trait.  

2. Phenotype refers to the expression of a genetic trait, that is, what the trait looks like.  

3. Purebred refers to the trait originating from homozygous genes from the offspring of true breeding.  

4. A recessive gene refers to a gene or trait, which is masked when a dominant allele is present.  

5. Self-fertilization refers to the procedure when a species that exhibits both male and female gametes makes the fusion of both the identical gametes to produce offspring.  

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.
