Which statement correctly explains why chlorophyll production decreased in the seedlings kept in the closet?
The seedlings in the closet had decreased chlorophyll production because they were not exposed to sufficient light for photosynthesis to occur. Chlorophyll is necessary for capturing light energy to drive photosynthesis, so without light, its production decreases.
What best explains why sunlight is a symbol for growth and life?
the apartment has little of it while the house has a lot (apex)[the raisin in the sun]
Which best explains the role of plant pigments in photosynthesis?
Plant pigments, such as chlorophyll, trap sunlight and absorb specific wavelengths of light. These pigments then transfer this energy to the chloroplasts where photosynthesis takes place. During photosynthesis, the energy from sunlight is used to convert carbon dioxide and water into glucose and oxygen.
During photosynthesis sugar C6H12O6 is produced from carbon dioxide water and sunlight Which statement BEST explains what happens during photosynthesis?
Electrons (with accompanying protons) are added to CO2 during photosynthesis.Electrons (with accompanying protons) are removed from CO2 during photosynthesis and added to water molecules to form sugar.Hydrogen is added to CO2 during photosynthesis.Oxygen is removed from CO2 during photosynthesis.
The air water temperature soil and sunlight in an ecosystem have no effect on organisms that live in the area?
This statement is incorrect. Air temperature, water availability, soil quality, and sunlight are key factors that determine the types of organisms that can live in an ecosystem. Organisms have specific adaptations to survive in different environmental conditions, and any changes in these factors can impact their survival and reproduction.
A garden hose that had been lying on a green lawn for several days was removed Which statement best explains the presence of yellow grass in the area where the hose had been?
4) The lack of sunlight under the hose affected chlorophyll production
What explains the global drop in temperature?
Added particles in the atmosphere keep some sunlight from reaching Earth. Source: WWW.AEULS.COM
What statement does a low order explosive resemble when exposed to air and sunlight?
dark brownish rocks
What is the function of sunlight in iodine solution?
Sunlight can help catalyze the reaction between iodide ions and iodate ions in an iodine solution, leading to the formation of free iodine. This reaction is important in the process of determining the concentration of vitamin C.
Is a hypothesis a question?
A hypothesis is not a question. If you are in Jr. High or something near that, you can use the structure: If......, then.... to state your hypothesis. For example: If I place one plant in a closet and one plant in the sunlight, then the plant in the sunlight will grow faster.
What is the function of sunlight in the bromine water and iodine solution tests?
Sunlight is used in the bromine water and iodine solution tests to provide the energy needed for the reactions to occur. The UV light in sunlight promotes the oxidation of bromide ions to form bromine and the oxidation of iodide ions to form iodine, which are key reactions in these tests.
Why does bromothymol blue stay blue in sunlight?
Bromothymol blue stays blue in sunlight because it is a pH indicator that changes color based on the acidity of the solution it is in. In neutral or basic conditions, it appears blue, which is more stable in sunlight.
What is a tentative statement about the natural world that can lead to a testable deduction?
A tentative statement could be that plants grow faster in sunlight than in darkness. This can lead to a testable deduction that if plants are exposed to sunlight, they will exhibit more growth compared to plants kept in darkness over a period of time.
What is a testable statement that predicts the relationship between two variables?
A testable statement that predicts the relationship between two variables is known as a hypothesis. For example, "Increasing the amount of sunlight a plant receives will result in higher rates of photosynthesis." This statement can be tested through experimentation by measuring photosynthesis rates under varying sunlight conditions. A clear prediction allows for empirical investigation and validation.
Which statement correctly explains why chlorophyll production decreased in the seedlings kept in the closet?
The seedlings in the closet had decreased chlorophyll production because they were not exposed to sufficient light for photosynthesis to occur. Chlorophyll is necessary for capturing light energy to drive photosynthesis, so without light, its production decreases.
What statement best explains why different areas of the Earth have different amounts of heat energy?
Different areas of the Earth receive varying amounts of heat energy due to differences in sunlight exposure, which depends on factors such as latitude, altitude, and cloud cover. The tilt of the Earth's axis causes variations in the angle at which sunlight reaches the surface, leading to seasonal temperature changes. Ocean currents and land features also play a role in redistributing heat across the planet.
What factor explains why tundra biomes remain cold year round but taiga biomes have alternating warm and cold seasons?
The factor that explains this difference is latitude. Tundra biomes are located at high latitudes where they receive less direct sunlight year-round, leading to consistently cold temperatures. Taiga biomes, on the other hand, are located at lower latitudes where they experience more seasonal variation in sunlight and temperature.
