Answer:
22
Explanation:
the thermometer goes by 2
Answer:
Ss and ss
Explanation:
<em>Since the smooth trait (S) is dominant over the wrinkle trait (s), the genotype of the wrinkled pea parent is definitely </em><em>ss</em><em>.</em>
<em>Also, some of the progeny had wrinkled pea texture (ss). Each of the 2 wrinkled alleles must have been donated by each of the parent. It thus means that the smooth pea parent is heterozygous for the trait (</em><em>Ss</em><em>).</em>
Now, let us look at a cross between the two parents;
Ss x ss
Progeny: Ss, Ss, ss, ss.
Phenotypically, 50% of the progeny are smooth peas while 50% are wrinkled.
Looking at the population of each of the phenotype resulting from the cross. 252:247 is approximately a 50:50 ratio.
Hence, the genotypes of the two parents are Ss and ss.

Answer:The based on this information interaction between these two species can best be described as COMPETITION. Correct option is B
Explanation:
Competition occurs between two species that shares the same requirements ( especially food) for survival.
Both the Western Toad and the Bull Frog has a similar niche because they require the same type of food (beetles, bees, and small aquatic insects) to survive in the environment of Arroyo Seco. Only one of the species will coexist in that environment and it's usually the survival of the fittest.
This explains the competitive exclusion principle proposed by Georgii Gause in 1934.
