A plant species has two alleles for petal color: pink and white. The pink (A) allele is
dominant. If a true breeding pink flower is crossed with a carrier pink flower, what is the
probability in a percentage) that their offspring will be born as carriers for the white
flower trait? Use a Punnett Square to justify your answer

Answer:

There's no such thing as a carrier pink flower, as pink is a dominant trait. Only carrier white flowers are possible because white is recessive.

If you meant carrier white flower, the percentage of offspring born as carriers for the white flower trait is 50%

Explanation:

Punnett squares are in the image

Here is data from a study on second-hand smoke and lung cancer: Ten thousand (10,000) people
that have lived with smokers for at least 10 years were studied. Seven hundred and forty (740) of
these people got lung cancer. Therefore, 7.4% of these people got lung cancer. Their conclusion is
second-hand smoke causes lung cancer. Do you agree or disagree with their conclusion? Explain
your answer by using ONLY the data provided in this question.

A striped billiard ball rolls and strikes a motionless solid billiard ball. The solid ball then begins to roll.

Which best describes the change in the magnitudes of momentum for the balls?
The change is greatest for the solid ball.
The change is greatest for the striped ball.
The change is the same for each ball.
The change depends on the direction each ball rolls.

How does using public transportation to get to school or work help slow
down climate change?
Select one:

The fuel consumption of public transportation is less per passenger.

Public transportation is faster. Traveling fast allows you to burn less fuel.

Now that we have studied the various types of vaccines, consider the current resurgence of diseases like the measles. How can we convince the general public and possibly even ourselves, that immunization is a necessary preventative measure for diseases that have serious complications? Is there a different schedule that we should consider? Are some forms of vaccines safer than others? Should we spread out the inoculation schedule to prevent confusion of a young person?

You perform an experiment using an aquatic plant to determine which color of light is most effective at driving photosynthesis. You take three plants, immersed under water, place plant A under blue light, plant B under red light, and plant C under green light. You notice bubbles coming off the leaves. More bubbles are coming from plants A and B, than plant C. How do these results determine which color of light is most effective at driving photosynthesis

In horses, a black coat is dominant over a brown coat. Both parents are heterozygous.

What is the probability that their offspring will have a BLACK coat?

What is the probability that their offspring will have a BROWN coat?

In watermelons, the gene for green color is dominant over its allele for striped color. At another gene locus, the gene for short shape is dominant over its allele for long shape. These two allele pairs assort independently. If a plant with long, striped fruit is crossed with a plant that is heterozygous for both of these traits, what percentage of the offspring do you expect will be short and green

What is the elevation of hachure line A?
100 feet
50 feet
75 feet
125 feet

Because the incorrect answer was 100 feet (based on it being the first lower elevation than the last recorded elevation of 125 feet) And the question prior of What is the most likely elevation of X being 115 feet was also graded incorrect. Would the actual contour lines WITH the hachure lines ON THEM continue to elevate in C.I. 25 increments making the contour line that X is on, 150 feet and the contour line that A is on to be 175 feet? And then 125 feet would actually be the correct answer because it is the first lowest below 175 feet?
