Answer:
The evidence goes against A. Expanding Earth and B. Contracting Earth
B. Any organism that "shows" a heritable factor must be homozygous.
Let's go through all choices:
A. TRUE! One heritable factor may be dominant and mask the other factor called recessive.
B. FALSE! Heterozygous organism can "show" a trait as well. If there is one dominant and one recessive form, a dominant form will mask it and dominant trait will be expressed.
C. TRUE! An organism gets one form of the gene from the mother, and one from the father.
D. TRUE! That's why sperm or egg are called haploid.
Forward reaction is a reaction in which products are produced from reactants and it goes from left to right in a reversible reaction.
For example, if the focus is on respiration, the forward reaction is written as
C6H12O6 + 6O2 ---> 6CO2 + 6H2O
If the focus is on photosynthesis, the forward reaction is written as
6CO2 + 6H2O ---> C6H12O6 + 6O2
It’s a process called ginning
