Answer:

The question as the options lacking but based on the question we can infer the ANSWER

Based on the results of the experiment we can best say that urea will disrupt the function of the certain enzyme and that when the urea is removed the enzyme regained its function.

Explanation:

Denaturation is the term used to describe urea effect on the enzymes as it inactivates it by affecting it's secondary and tertiary function. In the process it’s 3D structural conformation is altered.

The finding that ___ can cause channel-swapping is consistent with early filter theories of auditory attentional selection.

"different ears"
According to <span>Broadbent's study, depending on which ear the stimulus was done, one of the channels were used. If both ears were used then there was a channel-swapping phenomenon that proved his theory of auditory attentional selection.</span>

emily wants to know how green, blue and red color light affects plant growth compared to natural light. (Hint: what light affect

MArishka [77]

Red and blue colored lights are most effective for plant growth.

Plant Growth is the dependent variable and light color is the independent variable. The rest are control variables.

A Control variable is the part of the experiment that we keep the same throughout all of the test subjects. An independent variable does not depend on other variables and a dependent variable does.

Allow me to explain. When we perform an experiment, many factors that can change the results, For this reason, it is common practice to keep many of them the same for all test subjects (In this case for all of the plants). This way we know that if changes are measured, they were not caused by these variables. These are what we call control variables.

An independent variable does not depend on other variables to remain the same. For example, the species of plant would be an independent variable, given that a plant cannot change its species because of other factors.

A dependent variable does change according to other variables and is often what we try to measure. For this example given, the dependent variable is how much the plant will grow with each colored light.

Knowing that plants rely on light to produce the energy needed to grow, we can <u>hypothesize</u> that applying different colors of light will have an effect on plant growth. To test this, we can create an experiment where we use:

Soil
amount of water
amount of light
species of plant
length of experiment

As control variables.

One group of plants will have blue light, another green, and another red. We can identify the color of light as an independent variable.

Since what we seek to measure is plant growth, we identify this as our dependent variable and measure it for each plant after a set amount of time, to compare results.

With this, you can confidently identify the control, dependent, and independent variables and how to use them in your experiment.

Q 1.23: what was the last name of the scientist whose experiment debunked vitalism?

kramer

It was Stanley Miller. He utilized electrical charges and chemicals from the environment to make amino acids.
The Miller-Urey test was quickly perceived as a critical achievement in the investigation of the starting point of life. It was gotten as affirmation that few of the key atoms of life could have been integrated on the primitive Earth in the sort of conditions visualized by Oparin and Haldane.
