Yes, it is possible.
In this case both of the parental plants were heterozygotes and they manifested dominant allele in their phenotype, which is round seed.
P: Aa x Aa
F5: AA, Aa, aA, aa - possible genotypes in fifth generations.
A- dominant allele (round seeds); a- recessive allele (wrinkled seeds)
Wrinkled phenotype is manifested only if there are two recessive alleles present.
The correct answer is natural selection. C is the answer!
Bacteria has a stronger resistance that usually produces even more resistant bacteria, and the cycle just repeats itself, making more and more resistant bacteria. This process is called Natural Selection.
Hope that helped!

B Nature selection for traits the allow for increased rates of reproduction and survival over traits that don't, is correct.
A is also correct
Answer:
<em>The statement that is incorrect is :</em>
<em>Robert wanted to see if his theory was true that cigarette smoke will influence web-building in spiders.</em>
Explanation:
A theory can be described as a descriptive explanation of a phenomenon which is supported by valid experiments and careful examination of facts. As Robert, has not conducted any experiments nor has proved his study with reference to facts, hence it cannot be considered as a theory.
Robert wanted to see if his observation was true that cigarette smoke will influence web-building in spiders will be the correct statement that could be used.
