Scientists observe a newly established population of sexually reproducing plants growing on the shore of a small island. an observable trait of the plant has two possible phenotypes. it is determined by a single gene, with the dominant allele having complete dominance over the recessive allele. the first generation had 26 plants with the dominant trait and 25 with the recessive trait. the data below is from the first six generations of this population: generation number of individuals with dominant trait number of individuals with recessive trait total number of individuals 1 26 25 51 2 102 0 102 3 375 125 500 4 469 156 625 5 562 188 750 6 255 200 455 answer each part of this question completely in the space provided. use the data to explain the changes in phenotypic frequency from generation 1 to 3. do you think this population is in hardy-weinberg equilibrium? support your answer. propose a possible explanation for the change in phenotype frequency from generation 5 to generation 6.

Use the data to explain the changes in phenotypic frequency from generation 1 to 3. I'm not sure how to explain the increase in the recessive trait for generation 2 to 3. How would a population go from p2+2pq=1 to q2≃.2?

Do you think this population is in Hardy-Weinberg equilibrium? Support your answer. No, I don't believe so, since the population seems to change constantly in both the total number in the population, as well as the number of individuals with each trait.

Propose a possible explanation for the change in phenotype frequency from generation 5 to generation 6. Perhaps a climate change or the introduction of some new factor such as a drought or new preadator?

the answer is "a.) well–developed vascular system."

explanation:

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
