Your teacher asks you to design an experiment that shows how plants respond to changes in their environment. You have two identi

cal plants to do your experiment, and you may add any other equipment of your choosing. Using the scientific method, design an experiment that meets your teacher’s criteria.
Match each step of the scientific method with a step of the experiment.

A. Make observations.

2. Ask a question.

3. Test the hypothesis.

4. Analyze the results, and make a conclusion.

5. Test or modify.

A. Put one plant under a white lightbulb, and
place the other plant under a red lightbulb.
Measure the growth of the two plants.

B. If you observe no change, repeat the experiment with different colors of lightbulbs. If there is a change, repeat the experiment for one or two more trials to ensure that the color of the lightbulb contributes to the change.


C. Do plants grow as well under a different
color of light?


D. Determine whether the plant grown under the white lightbulb or the plant grown under the red lightbulb grew better.


E. Plants grow well under sunlight or a lightbulb
with a hot, white light.

Answer:

1.  Make observations.

Determine whether the plant grown under the white light bulb or the plant grown under the red light bulb grew better.

Observations are anything we notice which lead to a question in our mind.

2. Ask a question.

Do plants grow as well under a different color of light?

As this is a question being asked, hence it will be the question for the scientific method of research.

3. Test the hypothesis.

Put one plant under a white light bulb, and  place the other plant under a red light bulb.  Measure the growth of the two plants.

To test the hypothesis, experiments are performed. This is the experiment.

4. Analyze the results, and make a conclusion.

Plants grow well under sunlight or a light bulb  with a hot, white light.

After the experiments, the results are compiled and a conclusion is drawn.

5. Test or modify.

If you observe no change, repeat the experiment with different colors of light bulbs. If there is a change, repeat the experiment for one or two more trials to ensure that the color of the light bulb contributes to the change.

If our hypothesis does not come out to be true, then another hypothesis can be generated and tests be done for it.

Why are tigers and lions able to mate to produce cubs,but those cubs would not be able to go on to produce any off spring
Sveta_85 [38]

Answer:

Tigers and lions able to mate to produce cubs,but those cubs would not be able to go on to produce any off spring because their sex chromosomes do not match.

Explanation:

  • Tigers and lions mate to produce ligers and tilons but they do not produce viable sperms or egg.
  • In an organism there are two copies of chromosomes present in the somatic cells.
  • But in case of sex cells they receive each set from mother and father. which they duplicate and divide during formation of gametes via meiosis.
  • in such case if the sets are recieved from two different species then after pairing a mismatch will occur in the gene loci.For example, a eye colour gene may correspond to a paw length gene.
  • Thus the gametes when produced will not be viable.

A mixture of gases has 0.3000 mol of CO2, 0.2706 mol of SO2 and 0.3500 mol of water vapor. The total pressure of the mixture is
notka56 [123]

Answer:

Partial pressure SO₂ → 0.440 atm

Explanation:

We apply the mole fraction concept to solve this:

Moles of gas / Total moles = Partial pressure of the gas / Total pressure

Total moles = 0.3 moles of CO₂ + 0.2706 moles of SO₂ + 0.35 moles H₂O

Total moles = 0.9206 moles

Mole fraction SO₂ = 0.2706 moles / 0.9206 moles → 0.29

Now, we can know the partial pressure:

0.29 = Partial pressure SO₂ / Total pressure

0.29 = Partial pressure SO₂ / 1.5 atm

0.29 . 1.5atm = Partial pressure SO₂ → 0.440 atm

Explain how a heater warms the air in a room, including the words density, volume, and temperature in your explanation
seropon [69]

Answer:

Explanation:

Convection currents are created when the air above your radiator heats and then cools and is then heated again. This process happens continuously whilst you have your heating on and the current moves the heat around the room making it nice and warm and toasty.
