Answer:

The correct answer is -

The independent variable - Humidity levels

The dependent variable - Height

The control group - Tree kept outside of the greenhouse

Explanation:

In this study or experiment, the independent variable is the different humidity level as it is what is changed in the study to see its effect on the growth of the redwood tree. The independent variable is manipulated in the experiment to see the change or effect in the dependent variable occurs.

The dependent variable is the variable which \depends on the independent variable as the Independent variable manipulated the dependent variable is measured to the effect which is the height of the redwood trees here.

The control group is a groub of subjects that did not get the treatment that experiment group recieves as it is kept for analysing the deviation from the natural condition. The control group is the redwood trees that are kept in natural environemnt outside of the greenhouse.

A scan of Sam's genome for the 100 most common mutations known to cause RP didn't find anything. How can you explain this result
yan [13]

Answer:

He is either not carrying the gene for RP or the RP gene has mutated.

Explanation:

RP or Retina Pigmentosa is an eye defect inherited by a person from a parent. The disease is degenerative as the individual gradually loses his sight. It normally starts off as night-blindness and could go as bad as a total loss of sight.

The mutation of both the RPGR and RP2 genes which are responsible for the function and structure of light-reception in the eye accounts for most cases of Retina Pigmentosa disease.

In the presence of DCPIP which statements would be true? (for this and other questions, assume there is an inexhaustible supply
Margarita [4]

Answer:

<u>The correct statements are A and D</u>

A.The photo-system will still continue to split water because it is still losing electrons

D.The ATP yield would be unaffected

Explanation:

DCPIP is a redox-sensitive dye, not an electron transport chain blocker, and hence, imparts change in the wavelength when electrons are transferred. This allows rest of the steps of photo-system to be carried on normally, including splitting of water to generate oxygen as well as generation of ATP.
