"Untreated water from a factory flowing into a lake" is an example of point source pollution.
Why? You can actually point to a specific source- the factory. Runoff isn't considered point source.

Answer:
The proportion of the genotypic recombinants among the offspring from this cross is 75%
Explanation:
Separating the alleles from the parents independently, We have AB, Ab, aB, and ab.
These should be crossed using punnet's square, we will therefore get the genotypic of the 16 progenies as: AABB, AABb, AaBB, AABb, AAbb, AaBb, AaBB, AaBb, aaBB, AaBb, Aabb, aaBb, aabb, aaBb, Aaaa and AaBb. From these, only those in bold retained the genotype of their heterozygous parents. Therefore, 12 out of 16 are genetic recombinant, which are the offspring that differs from their parents after a cross. This made the proportion to be 12/16 X 100 = 75%.
Each codon codes for an amino acid.
Together, they code a protein but that’s not part of the question.
Amino acid is your answer.

Answer:
The possible genotype of this cross is RW
Explanation:
This question involves a single gene coding for radish color. The allele for red radish (R) is incompletely dominant over the allele for white radish (W), hence, a third intermediate phenotype is formed when they combine (RW).
In this cross, a pure-breeding red radish (RR) is crossed with a pure breeding white radish (WW) to create the F1 offspring. The red radish will produce gametes R while the white radish will produce gametes W, hence, using a punnet square (see attached image), the F1 offspring will have the genotype: RW.
