Answer:
Hydrogen and electrons
Explanation:
Nicotinamide adenine dinucleotide (NAD) and flavin adenine dinucleotide (FAD) serve as reducing power during energy transfers. One NAD+ accepts one hydrogen ions and two electrons and becomes reduced into NADH. Likewise, FAD accepts two hydrogen ions and two electrons and is reduced into FADH2. Oxidation of NADH and FADH2 into NAD+ and FAD respectively releases both hydrogen ions and electrons.
For example, some of the energy of glucose released during glycolysis and Kreb's cycle is temporarily stored in the form of NADH and FADH2. Oxidation of NADH and FADH2 via electron transfer chain of mitochondria releases both electrons and hydrogen ions (protons). The protons are pumped across the inner mitochondrial membrane to generate the proton concentration gradient.
B. because the match contains phosphorus, and it is unlit, so it has chemical POTENTIAL energy
Answer:
D. The tubes allow water and nutrients to be transported throughout
the plant.
Explanation:
option D supports the description of the cells. The long , vertical tubes transport water and nutrients and are most likely xylem and phloem vessels.
option A is wrong since, chloroplasts inside the cell helps in absorbing sunlight.
option C is also wrong, because water loss is controlled by the stomata in the leaves and they are not long tubes.
option B could possibly be right but option D is better suited.
Answer:
Virtual learning will help me grow as a student by forcing me to step out of my comfort zone and explore different learning opportunities. Learning online is a challenge that I hope to overcome. Even though school will be very different, I know that this is just a learning curve that will help me become a better student and person overall.
Answer:
The epicenter and hypocenter are two important points in causing earthquakes.
Both the epicenter and hypocenter are different from each other in the following basis:
Location: Hypocenter is present within the earth surface where an earthquake rupture starts and the epicenter is located in the earth's crust just above the hypocenter where a seismic rupture begins.
Associated waves: Seismic waves propagate from the hypocenter caused by seismic velocity and rock density which reaches the epicenter where P and S waves hit the surface of earth.
