Radish flowers may be red, purple, or white. A cross between a red-flowered plant and a white-flowered plant yields all-purple offspring. The part of the radish we eat may be oval or long, with long being the dominant characteristic. The flower color trait in radishes is an example of which of the following?
A) a multiple allelic system
B) sex linkage
C) codominance
D) incomplete dominance
E) epistasis

Answers

The answer is D) incomplete dominance.

Incomplete dominance occurs when heterozygous phenotype is intermediate to the dominant homozygous and recessive homozygous phenotypes. In radish flowers, purple is intermediate to white and red flowers. So, purple color is characteristic for heterozygous phenotypes. When dominant red flowers are crossed with recessive white flowers, all offspring will be heterozygotic and with intermediate - purple color.

Final answer:

The flower color trait in radishes, as described in your question, is a classic example of incomplete dominance, as the offspring's phenotype (purple flowers) is a blend of the parental traits (red and white flowers).

Explanation:

The flower color trait in radishes, as described in your question, is an example of incomplete dominance. In incomplete dominance, neither allelic version of the trait is completely dominant, resulting in an offspring phenotype that is a blend of the parental traits.

In your presented case, neither the red flower trait nor the white flower trait is entirely dominant, which is why a cross between a red-flowered and a white-flowered radish produces all-purple offspring. This is a classic example of incomplete dominance in biology.

On a small island, three separate phenotypes of a single species of cherry tree occur- small, medium, and large seeds. A small population of mice is introduced to the island, The mice are the only organisms that eat cherries on the island. When they eat a cherry, they digest it and excrete the pit or seed completely undigested at another location. The mice choose the larger cherries with medium and large seeds and leave the smallest ones uneaten. a. What type of selection, if any, is occurring here? b. Provide support for your answer. c. Graph what the population of cherry trees will look like over time. Make sure to label your axes.

Answers

a. Natural selection is occurring in this scenario.
b. The larger cherries with medium and large seeds are being selectively favored by the mice, as they are the ones being eaten and dispersed to new locations. This leads to an increase in the frequency of the medium and large seed phenotypes in the population over time.
c. Unfortunately, as a text-based AI, I am unable to create visual graphs. However, over time, the population of cherry trees would likely show an increase in the medium and large seed phenotypes, while the small seed phenotype would decrease in frequency. The x-axis could represent time, and the y-axis could represent the proportion or frequency of each seed phenotype in the population.

What is caused by the disturbance of a supersaturated solution?A. instability
B. an explosion
C. liquefaction
D. precipitation

Answers

I think the correct answer from the choices listed above is option D. Precipitation is caused by the disturbance of a supersaturated solution. It happens because the solvent can no longer dissolve more of the solute so instead of being in the solvent it precipitate out.

Which of the following best explains why soil conservation is important to human agriculture

Answers

The bare soil surface type affects the amount of runoff because it has no other stopping mechanism that prevents runoff to happen. Just like in the use of pesticide, it is harmful to human agriculture because it contains an antifreezing chemical (present in transportation vehicles). When the chemical seeps into the soil, it will create a runoff and can seep into the groundwater causing pollution.

 
It is easier to prevent the degradation of old soil than it is to generate new soil.
