<span>The connections between cells become weakened, and the leaves break off with time. Many trees and shrubs lose their leaves when they are still very colorful. Some plants retain a great deal of their foliage through much of the winter, but the leaves do not retain their color for long.</span>
Answer:
Cell wall synthesis
Explanation:
Antibiotics are the compounds that work against bacteria and kills bacteria or slow their growth. Every antibiotic have their own mode of action. Beta-lactam antibiotics like penicillin and cephalosporins work on cell wall synthesis.
They stop the synthesis of peptidoglycan by inhibiting the transpeptidation reaction. So when no new cell wall is added into bacteria, holes creates in the cell wall which allows the free movement of solute inside the bacteria cell that results in osmotic lysis of the bacterial cell. Therefore the right answer is cell wall synthesis.
Answer: Hydroelectric power will be the best energy source.
Explanation:
<u>Solar energy-</u> It refers to the energy that is directly derived from the sun, and are later used to convert into some kind of electrical or thermal energy. For example, solar panels.
<u>Biomass energy-</u> It is a type of energy that are directly obtained from the plants as well as organisms. This can be regenerated again and again. For example, bio-gas and food crops.
<u>Hydroelectric power-</u> It is a type of energy that is collected, from the rapid motion of water. A dam is needed to construct across a narrow river, which will store water as a reservoir. And this water, when allowed to flow then it initiates the movement of the turbines and due to this continuous motion of the turbines, electricity is generated.
Thus, the most efficient energy source for the given area is the hydroelectric energy, that fulfills the condition for setting up dams in the two rivers, which will generate a huge amount of electricity.
This should be correct, but it is not a 100% guarantee on my part.
