A
biological catalyst that speed up the rate of chemical reaction in the body is
known as Enzymes. Many processes in the body depend majorly on enzymes and they usually function by forming enzyme- substrate complex. However, large
temperature and pH will cause the enzymes to denature this is because all
enzymes are proteins and these extreme conditions will affect the bonds in
their tertiary structure.
Answer:
25% of the heterozygous cross are short, and the offspring of a homozygous dominant and homozygous recessive pea plant will always display the dominant trait (phenotype), because they are heterozygous.
Explanation:
In this explanation, I'm assuming that the allele "T" for tall plants is dominant to the allele "t" for short plants, like in Gregor Mendel's pea plant experiment.
A homozygous tall pea plant will have the genotype "TT" and a homozygous short plant will have the genotype "tt" because homozygous means that both alleles are identical. Since "T" is dominant over "t", any plant with at least one "T" allele will be tall (the dominant trait), regardless of what the other allele is. Let's look at a Punnett square for this cross:
Explanation:
