List molar concentrations (0.0 M, 0.2 M, etc.) at which water entered the potato strips. Why did water move into the potato stri
kati45 [8]

Answer:

- Water entered the potato strips because the potato cells contained higher concentration of solutes than its external environment.

- The solutions are hypotonic to the solution in the potato cells.

Explanation:

According to osmosis, water will move from a region where it is high in concentration to that region where it is low in concentration. However, a region with high solute concentration contains a low water concentration and vice versa.

Hence, according to this question, water is said to move into potato strips from solutions of molar concentrations like 0.0M, 0.2M etc. Water moved into the potato strips because potato cells contained higher concentration of solutes than its external environment. This means that the external solutions are HYPERTONIC i.e. low in solute concentration to the solution in the potato strips.

in a 3-point cross, crossovers that occur during the formation of which gametes can be scored using the phenotype of f2 progeny?
JulsSmile [24]

In gametes generated by F1 tri-hybrids and gametes produced by parents from true-breeding populations.

When non-sister chromatids of homologous chromosomes exchange genetic material during meiosis, novel allelic combinations are created in the daughter cells. The locations of three genes in the genome of an organism are identified using a three-point cross. A homozygous recessive individual is crossed with a person who is heterozygous for three mutations, and the progeny's phenotypes are graded. When F1 progeny are self-pollinated, a 3:1 ratio of F2 progeny are created.
