When scientists are doing research to determine how the environment affects a life form, it often takes many years to reach a co
nclusion. Why do you think that is the case? a.
Many environmental factors must be considered (water, light, and temperature were just three that were investigated in this simulation).
b.
Many tests must be performed because variables need to be tested one at a time (first test for water effects, then test for light effects, etc.).
c.
Some effects take a long time to become noticed, so the experiments often have to take place over long periods of time.
d.
All of the above.

An organism which has two different alleles of the gene is called heterozygous. Phenotypes (the expressed characteristics) associated with a certain allele can sometimes be dominant or recessive, but often they are neither.
two of the gametes will Java chromosomes identical to the chromosomes found in the original diploid cell,while two of the gametes will have chromosomes that are different
