Answer:
1. Plants are green due to presence of green pigment chlorophyll in their chloroplasts.
2. ATP is used to make organic sugars (glucose)
Explanation:
Chlorophyll pigments absorb the light in the blue and red regions and reflect all the green light. When the reflected green light reaches our eyes, the plants look green in color. The color of the object is determined by the color of the reflected light.
Splitting of water during the light-dependent phase of photosynthesis and electron transfer through cytochrome b6/f complex generates the proton concentration gradient which in turn drives the synthesis of ATP. Calvin cycle refers to the set of reactions that fix the atmospheric CO2 into organic sugars such as glucose. The ATP molecules formed during light reactions are used to drive the endergonic reactions of the Calvin cycle.
Germination is B. the process that occurs when the seed swells and breaks and growth occurs.
Answer:
During the water cycle, the water on the earth's surface gets evaporated leaving the impurities behind and enters into the atmosphere as water vapor. Thus, the water cycle removes pollutants from earth’s water.
Explanation:
Water cycle is the continuous movement of water on the earth's surface and the atmosphere. Some of the water from the oceans, lakes, rivers etc gets evaporated by sunlight and enters into the atmosphere as water vapor. Also from the processes like sublimation (ice and snow) and evapotranspiration (plants), water vapor reaches the atmosphere. This vapor is then condensed into clouds and later falls back from the sky on to the earth's surface as precipitations like rain, snow etc. During the evaporation, the pollutants (impurities) in the water sources are left behind. Thus, the water cycle removes pollutants from earth’s water.
Answer: Nuclear Fusion occurs when the nuclear components of an atom combine.
