Plants remove carbon from the atmosphere in the form of CO2 and store it in their structures. How can rapid deforestation affect the carbon cycle? What can be done to reduce the effects? Explain.

Answers

Answer:

Explanation:

Deforestation affects carbon cycle through the Greenhouse gas effect and global warming. Green plants, trees and forest helps to balance the amount of Carbon in the atmosphere, carbondioxide is used up by plant through the process of photosynthesis in which plants make their own food. When there is excess amount of carbon dioxide in the atmosphere as a result of deforestation ‘blanket’ of carbon dioxide is formed which traps heat and prevents it from leaving the earth surface in the atmosphere. This accumulated heat leads to global warming in the environment.

More trees should be planted to prevent rise in atmospheric a carbon and deforestation should be prevented.

Answer:

Deforestation has an effect on the Carbon Cycle also known as the Greenhouse gas effect and global warming. Trees and forest balance the amount of Carbon in the atmosphere through the process of photosynthesis in which plants make their own food with carbon dioxide. And when we remove the plants that turn CO2 into breathable air we have more CO2 over all.

A personal trainer thinks her clients get better workouts and are stronger if they listen to music while working out. Over the next week, she divides her 20 clients into two groups of 10. For the first group, she plays music and sees if they can lift a barbell weighing 50 lbs. For the second group, she repeats the test but does not play any music. All 10 members of the music group could lift the barbell, but only 7 members of the no music group could lift the barbell. She concludes that her hypothesis was correct and decides to always play music for her clients.



Which group was the control group?

Answers

Answer:

The correct answer is: the group of 10 people that lifted the barbell with music is the control group.

Explanation:

The personal trainer made an experiment to test her hypothesis. When experiments are being made, is common to have a control group and an experimental group.

The control group is the one that is subjected to the usual conditions, the group that shows what normally happens. The experimental group is the opposite, this group is observed while it goes through an unusual condition that may impact how they perform in the task observed.

The personal trainer thinks that playing music for her clients is of benefit to them, so we can assume that she always plays music during the workouts, which means that the control group is the one that is listening to music while lifting a barbell. The group that worked out without music is the experimental group because they were the ones that performed that activity with a change in their normal environment.

You did an experiment where you want to test if a special kind of fertilizer will actually help your apple tree produce a lot of apples. To do the experiment you went to your local nursery and purchased two of the same kind of apple trees. You planted both trees in your sunny backyard , gave both of them the same amount of waterbut you gave one tree the special fertilizer and the other tree with the regular old fertilizer you've used before . After about a month , you noticed that the tree that got the special fertilizer grew over 100 apples than the other tree that grew about 40 apples . From this experiment , which of the following is considered the dependent variable ?

Answers

Answer:

Dependent variable: number of apples

Explanation:

In an experiment, the independent variable is the variable that isn't modified by the other variables measured in the experiment. In the example above indicated, the independent variable is the fertilizer used in the experiment. On the other hand, the dependent variable is the variable tested or measured in the experiment, thereby this variable is 'dependent' of the independent variable.

If you were on the moon, and you were trying to move a 20-lb bowling ball and a 3-foot cube of Styrofoam, which item would take more work to move? Why?

Answers

Answer:

The 20 lb bowling ball would take more work to move. This is because it has more mass

Explanation:

It is the bowling ball that will take more work to move. The reason for this is simple. Mass is constant anywhere, whether it is on the moon or on the earth.

It is the acceleration due to gravity that is different in both places. Work as we all know is a factor of mass, the higher the mass, the more work it will take to displace the mass from its position.

Thus, because the mass of the bowling ball is greater, it will take more work to move than the styrofoam
