The introduction of the herbivores would disrupt the genetic equilibrium in the population because the herbivores would act as a mechanism of natural selection.
The presence of anthocyanin in the stem is determined by the presence of the dominant allele ANL, so the genotypes of the plants that have anthocyanin are ANL/ANL and ANL/anl. The plants that do not have anthocyanin in their stems are homozygous for the anl allele and the herbivores would eat these plants more often, reducing the frequency of the anl allele in the population.
Marble A moved first, and marble B moved last, thats why marble A moved farther, sorry if im wrong
Answer:
From the whole progeny of 544 plants, 34 individuals are expected to have short stems and white flowers.
Explanation:
<u>Available data:</u>
- short stems coded for by recessive allele t
- white flowers coded for by recessive allele p
- T codes for tall stems
- P codes for purple flowers
- Cross between two heterozygous individuals
- Total number of the progeny 544
In a dihybrid cross, it is expected to get a phenotypic ratio of 9:3:3:1
Cross:
Parentals) TtPp x TtPp
Gametes) TP Tp tP tp

F1)
- 9/16 T-P-
- 3/16 T-pp
- 3/16 ttP-
- 1/16 ttpp
(<em>Note: The "-" symbol represents either a dominant allele or a recessive one</em>)
From these possible genotypes and phenotypes, we can get their corresponding amount of individuals
16 ---------- 544 individuals
9 ------------X = 306 individuals tall stems and purple flowers T-P-
3-------------X = 102 individuals with tall stems and white flowers T-pp
3------------ X = 102 individuals with short stems and purple flowers ttP-
1 ------------ X = 34 individuals with short stems and white flowers, ttpp
Answer:
Explanation:
The Krebs cycle, named after 1953 Nobel Prize winner and physiologist Hans Krebs, is a series of metabolic reactions that take place in the mitochondria of eukaryotic cells. Put more simply, this means that bacteria do not have the cellular machinery for the Krebs cycle, so it limited to plants, animals and fungi.
Answer:
The Isopropanol had a lower heat of vaporization than that of water, meaning that it didn't have to have as much energy to accomplish a phase change, in this case evaporation.
