POINTS Aliah conducted an experiment to determine respiratory rates during different activities. She counted the number of breaths per minute. Aliah noted that the number of breaths increases as physical activity increases. Why is there an increase in the number of breaths per minute as activity increases?

A) As activity increases, breathing becomes more efficient.

B) As activity increases, the rate of the heart beating increases.

C) As activity increases, the oxygen needs of cells increase.

D) As activity increases, more oxygen is exhaled.

In some plants, pointed leaves (p) are dominant over rounded leaves (p). a plant with a genotype of pp

What is the relationship between absorbance of light and the rate of photosynthesis?

Scenario 5 1) take 10 red and 10 black beans and place them, mixed, on the table. record the starting phenotype # and frequencies (% of your total population) of your starting population in the table provided (generation 0). 2) act as a predator. “capture” as many organisms as you can until you have reduced the population to three organisms. put them aside. at this point, the predators die. 3) the remaining organisms each produce 2 clonal offspring. multiply your organisms accordingly and allow them to mix on the table. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 1). 4) repeat the reproduction event, allowing each of your organisms to produce 2 clonal offspring. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 2). 5) repeat the reproduction event, allowing each of your organisms to produce 2 clonal offspring. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 3).
