Scientists are interested in how the severity of acid deposition affects the soil of the red spruce forests. They design a labor

atory experiment in which rainwater of different pH values is used to water soil samples taken from red spruce forests. The soil samples are the same size and contain the same ratios of sand, silt, and clay. The same amount of water is sprayed on the soil samples every day for a week. Through the experiment, the scientists measured the concentration of toxic forms of aluminum in the soil samples. Identify the likely scientific question being investigated in the experiment.
A. How does the amount of aluminum in the soil affect the pH of the rainwater?
B. How does the pH of rainwater affect the concentration of aluminum in the soil samples?
C. How does the composition of the soil affect the pH of the rainwater?
D. How does the number of days watered affect the concentration of aluminum in the soil samples?

The best question for this experiment is How does the composition of the soil affect the pH of the rainwater?.

<h3>What are the best factors being studied?</h3>

The main factors based on the description are:

  • The pH of the rainwater: This is the factor manipulated by the researcher.
  • The aluminum concentration: This is the factor researchers are evaluating.

<h3>What is the best question?</h3>

The best question would be one that relates the main two factors. Based on this, the best question would be: "How does the composition of the soil affect the pH of the rainwater?".

How can the presence of one species benefit another in the same ecosystem
tekilochka [14]

Answer:

The different species present in an ecosystem make the ecosystem balanced.  The species of an ecosystem interact with one another in one form or the other. For example, the presence of a plant species will provide food for the abundant types of herbivores present in an ecosystem. A predator might feed on many types of preys. Hence, the presence of different preys will reduce the chances of a species from becoming wiped out from the ecosystem. Hence, all the organisms in an ecosystem are dependent on another in some way or the other.

If you were to repeat the Meselson Stahl experiments, but rather than use N15 and N14, you use P32 and P31, how would the result
bonufazy [111]

Answer:

The correct answer will be option-C

Explanation:

The CsCl gradient centrifugation in Meselson Stahl experiments is done to separate the bands of the DNA containing isotopes on the basis of difference in the density.

In the experiment, bacterial cultures were grown in the medium of 15N and 14N but if we repeat the experiment with P32 and P31 instead of 15N and 14N and centrifugation is performed then the banding pattern will be the same as of the previous experiment as the method of the replication is same that is semi-conservative.

Thus, Option-C is the correct answer.

What is the relationship between convection currents, seafloor spreading, and the formation of ocean basins?
beks73 [17]

Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of the seafloor.
