Answer:
a. The electrons provide energy for the H+ pump to transport more H+ ions into the thylakoid space.
d. The photolysis of water releases H+ ions into the thylakoid space.
Explanation:
This question describes the first stage of photosynthesis, which is LIGHT-DEPENDENT REACTION. The light dependent reactions involve creating ATP (energy carrier) and NADPH (electron carrier) needed for the Calvin cycle (light independent stage) to occur.
The ATP is formed by pumping hydrogen ions (H+) into the thylakoid space/lumen, hence, creating a electrochemical gradient needed for ATP synthase to synthesize ATP. The buildup of H+ ions is caused by:
- The electrons that arise when light photons hit a chlorophyll molecule is used to provide energy for the H+ pump to transport more H+ ions into the thylakoid space.
- The photolysis of water results in the production of electrons (e-) and hydrogen ions (H+). These hydrogen ions are released into the thylakoid space.
<span>False. Sound *reflects* from the surfaces in a room, it doesn't "refract." Refraction is a distortion from passing through something (like light through glass).</span>
Gregor Mendel was a scientist born in the Austrian Empire in 1822. He
conducted pea plant experiments and established many of the rules of
heredity. He was explaining the significance of invisible factors ( now
called genes ) for the inheritance. He also experimented with hawkweed
and honeybees. Mendel is referred to as "The Father of Genetics".
Answer: Genetics.
Ewaste is a problem because it contains many hazardous chemicals like mercury, lead and cadmium which could seep in to the soil and eventually to the groundwater. This would lead to contamination of the drinking water. The most important thing to remember would be to separate this type of waste with the others. It would be better if you sell it or give it for reuse. Also, you can send it to a recycler that knows what to do with these wastes.
