Get twenty people, from various genders and ages, to be your testees. Create a random test that has both analytical and logical problems, and get the 'testees' (I have no idea if this is a word or not) to do the test before and after spending time outdoors.

An independent variable is how much time they spend outside, and the dependent is how well they function afterwards. (I think).

The constant is what stays the same, so most likely the tests in this case (if taking my example)

I don't really know what you mean by control, though...

This is what I would've done if it was my homework assignment, I'd suggest looking over my answers to see if they're accurate or not. Hope I helped, and good luck.

Which of the following scenarios is representative of how agricultural practices can affect the environment?
Citrus2011 [14]
<span>The correct answer to the question, 'which of the following scenarios is representative of how agricultural practice can affect the environment' is A. Option A is chosen because it is the only option that refer to another environment which is different from that of the farm. When fertilizers are washed to nearby ponds as a result of erosion, it causes a lot of negative changes in the pond. For instance, the chemicals in the fertilizer can be poisonous to some of the smaller organisms in the pond, this will result in the death of these organisms. Fertilizer run off can also cause excessive growth of plants such as algae in the pond. This may block out the light necessary for the survival of the organisms in the ponds and may also reduce the amount of oxygen available to the organisms living in the pond.</span>

How do enzymes act as catalysts? (Choose ALL that apply) They allow for fewer collisions of molecules (enzymes + substrates) The
vazorg [7]

Answer:

- They allow for more collisions of molecules (enzymes + substrates)

- They lower the amount of activation energy needed to complete the reaction.

- They speed up chemical reactions to form more products

Explanation:

Enzymes are proteinous molecules that serves as catalyst in living systems. Like every other catalyst, enzymes function to SPEED UP the rate of biochemical reactions by LOWERING/REDUCING the activation energy, which is the energy required for a reactant to form product (completion of reaction).

Enzymes like other catalysts causes faster movement of molecules in the reaction i.e. they allow for more collisions of molecules (enzymes + substrates). This causes the rate of reaction to increase and hence, speeden the reaction.
