Metals conduct electricity and heat, indicating that the electrons are free to move. Metals are malleable, showing that atoms are not in fixed positions but can remain bonded even though they change their positions. In metallic bonding, atoms donate electrons to a pool and all the atoms share in the pool. No compounds are formed, but the atoms are bonded into a network.
Answer:
1. reducing soil erosion,
2.Controlling runoff water
Explanation:
Contour farming mitigates the impacts of floods, storms and landslides on the crops by reducing soil erosion up to 50 percent, controlling runoff water, increasing moisture infiltration and retention and thus enhancing soil quality and composition
Answer:
Gene expression in all organisms depends on protein synthesis. What is the last stage in protein synthesis, in which amino acids are assembled by tRNA? translation. The steps in proteins synthesis are identical in all six organisms.
Answer:
True.
Explanation:
As we know, the plasma membrane of the cells is semi-impermeable, that is, it only allows the passage of some molecules in sizes and specific burning nature. Although the Na + and Cl- molecules are very small, they are polar, electrically charged molecules. These molecules are not well seen by the membrane, which does not allow them to pass into the intracellular medium.
The following chemical reaction, represents photosynthesis. Photosynthesis does not occur in an earthworm, a whale, or a rabbit. Therefore the answer is a rubber tree plant.
