CAM plants keep stomata closed in the daytime, thus reducing loss of water. They can do this because they - fix CO{2} into organic acids during the night.

The correct option is a.

As an adaptation to dry environments, certain plants developed a carbon fixation mechanism known as crassulacean acid metabolism, or CAM photosynthesis, which enables a plant to photosynthesize during the day but only exchange gases at night.

During the day, the malate is transferred to chloroplasts where it is transformed back to CO2, which is then utilised during photosynthesis. At night, the CO2 is stored as the four-carbon acid malic acid in vacuoles. The enzyme RuBisCO is surrounded by a concentration of pre-collected CO2, which improves photosynthetic efficiency. Plants in the Crassulaceae family were the ones that initially revealed this process of acid metabolism.

Answer:

1.Carbon dioxide is converted to sugar used for food. - 1. Location- A

2.Carbon trapped in fossil fuels is converted to carbon dioxide. - 2. Location- C

3.Organic carbon is converted to fossil fuels. -3. Location- E

4.Carbon dioxide is converted to carbonates.- 4. Location- D  

5.Sugar is broken down and converted to carbon dioxide.  - 5. Location- F

Explanation

1. Carbon dioxide is converted to sugar used for food: The carbon dioxide is converted into sugars by the process of photosynthesis, which occurs in the green plants. Plants trap carbon dioxide and sunlight from the atmosphere, to synthesize their food.

2. Carbon trapped in fossil fuels is converted to carbon dioxide: The fossil fuel produced deep inside the earth, acquired by the factory. From the factory the carbon dioxide liberated to the atmosphere.

3. Organic carbon is converted to fossil fuels: The organic carbon obtained after the degradation of organic matter is responsible for the synthesis of fossil fuels.

4. Carbon dioxide is converted to carbonates: The carbon dioxide from the atmosphere gets dissolved with water of the water body and termed as carbonic water.

5.Sugar is broken down and converted to carbon dioxide: The glucose or sugar as a source of food in plants gets broken down into carbon dioxide and water by the process of respiration.

Describe how heat affects the state of matter of a substance.<br><br><br>Thank you!❤​
Darina [25.2K]
Heat creates energy... the atoms move faster and faster, which changes the state of matter.
for example:
if a solid is heated, it turns to a liquid
if a liquid is heated, it turns to a gas

hope this helps?

Electromagnetic waves are all around us T or F
Law Incorporation [45]

Answer:

2. True, 3 True, 4 Trues, 5 False, 6 True, 7 True, 8 False, 9 True, 10 True

Explanation:

3. True , Electromagnetic waves have electric and magnetic energy while ocean wave have kinetic energy which is then converted into electrical energy.  

4. True, the distance between all the wavelength is same until and unless it not dampened or attenuated or amplified.  

5. False, Frequency measures the number of times an event takes place in a given time period.  

6.   True, the higher is the frequency , the more will be the energy

7. True, Gamma waves have highest frequency

8. False, our eyes could see only visible spectrum wavelengths

9. True, some object or surfaces reflect the wavelength while some absorb it.  

10.  True, all cosmic researches are driven by EM waves theory and related logic.
