Answer: Loess is the fine grained material that has been transported and deposited by the wind. The answer is <u>A.</u>
Explanation:
Since the wind can carry these types of material (find grained) father than sand, and also higher up, they are generally found very far from their original place of origin.
Loess is no larger than 50 micrometers in size. It is coarse in texture like clay, but finer than a grain of salt.
Answer:
This is nuclear fusion that happens in the core of stars. This is the process of converting hydrogens into helium. It is also converting mass into energy as the starting mass is higher than the finishing one, that missing mass is released as energy.
Explanation:
Plant cells do not perform respiration, so A,C, and D couldn't be correct but they don't digest either. so gain energy plants go through a light dependent reaction and the Calvin cycle which makes up photosynthesis.
The answer is; Sodium (Na+) and Potassium (K+) Ions
These cations are pumped out of the cell by Na+-K+ transmembrane protein pumps leaving the inside of the cell electronegative in relation to the extracellular matrix. This membrane potential is significant especially for neurons. Depolarization of the membrane enables transmissions of an impulse along the neurons.
Explanation:
In a food chain, only 10% of energy is transferred from one trophic level to another trophic level. If the energy produced at the producer level is 1000 J, then the energy available at the primary consumer level will be 100 J and energy available at the secondary consumer level will be 10 J.
