Mr. Smith wanted to see if the color of light shined on a plant had an effect on the number of leaves it had. He gathered 2 groups of the same species of plants, gave them the same amount of water, and did the test for the same amount of time. On one group of plants he used white light. For the second group he changed the light color to red.

Answers

Answer 1

Answer:

Final answer:

The color of light affects plants' growth and leaf production due to the role of different light colors in photosynthesis and the phytochrome system in plants. Chlorophyll mainly absorbs red and blue light from the light spectrum for photosynthesis, and far-red light can slow plant growth. Therefore, exposure to different light colors could result in different numbers of leaves.

Explanation:

The subject of the question is how the color of light affects the growth of plants, specifically the number of leaves plants produce. This experiment is primarily about the effect of light on plant's photosynthesis, a process that uses light to convert carbon dioxide and water into glucose. The glucose is utilized to fulfill various energy requirements of the plant's growth, including the growth of leaves.

Light has diverse wavelengths, with each color representing a different wavelength. While white light contains all the possible color wavelengths, the red light specifically contains a higher wavelength region. According to Sir Isaac Newton's experiment, sunlight, which looks white to us, contains all the colors of the spectrum.

In this context, the phytochrome system in plants plays a crucial role. Chlorophyll, the green pigment in leaves, absorbs mainly red and blue light from the light spectrum and uses that energy for photosynthesis. However, far-red light, which is one element of white light, is not absorbed. If a plant is exposed more to far-red light, it could slow its growth.

Consequently, the difference in the number of leaves that Mr.Smith observed in the plants under white light and those under red light might be due to the role of light color in photosynthesis and the phytochrome system in plants.

How do the bonds within AND between a water molecule affect the properties of water?

Answers

Water is a polar molecule, meaning the covalent bonds in it share electrons unequally. They spend more time around the oxygen, making it positive and the hydrogens negative. This helps water stick to surfaces, a property called adhesion. The hydrogens of one molecule are also attracted to the oxygens of another. This is called cohesion, and it helps water form droplets

When an inflated balloon is exposed to cold air,a. the temperature inside the balloon rises.
b. the pressure inside the balloon rises.
c. the volume of the balloon decreases.
d. the volume of the balloon increases

Answers

The correct answerwould be C. The volume of the balloon will decrease. As depicted in Charles’Law which states that volume and temperature are directly proportional to each other,when the pressure of the gas is at a constant. When this theory is applied, theballoon will decrease in volume when it is exposed to cold air because the gas pressureinside the balloon remains the same. It is easier to remember this concept withthe equation V/T = K where V is volume, T is Temperature and K is constantpressure.

Is aluminum rusting physical or chemical change

Answers

chemical because it can not be changed like cutting a piece of paper

Rusting is a chemical change .

My reason being is because the physical shape and structure of the object doesn't change.

The color , appearance , or look may change and if that happens than its a chemical change.

______________________________________________________

Example :

Since the aluminum is rusting it probably turned red or orange , but the shape and size is still the same.

I really hope that this helps you out a lot , have a nice day.
