Answer:
Variable expressivity, Incomplete penetrance, Phenocopy, Genetic heterogeneity
Explanation:
Phenocopy: When an environmentally caused phenotype mimics one that has a genetic basis. The variation in phenotype caused by environmental conditions exists in such a way that the organism's phenotype matches a phenotype which is determined by genetic factors.
Variable expressivity: When a characteristic is subject to a range in severity or degree of expression in the phenotype.
Genetic heterogeneity: When the same phenotype/disease can be caused by different genes.
Incomplete penetrance: When individuals have a genotype that specifies a particular phenotype but that phenotype does not develop.
Streptococcus lacks an electron transport chain. How does this bacterium reoxidize NADH? Where is the NADH formed?
C) water is needed for the photosynthesis to occur
CO2 + H2O --> glucose + O2
the atoms of C, H, and O must combine to form glucose
