Answer: The percentage of the helium will increase with the decrease in the percentage of the hydrogen.
Explanation:
The conversion of the hydrogen into helium occurs by the nuclear fusion of the hydrogen atoms. This process reduces the hydrogen density and reduces the energy production inside the core region. Typically, in the core region of the hydrogen is converted into the helium by nuclear fusion. Four hydrogen atoms are collectively fuse to form one atom of helium. This process involves the production of heat energy.
Whereas a change that causes change in chemical composition of a substance is known as chemical change. For example, A new substance is always formed in a chemical change. Thus, we can conclude that the definition a chemical change produces a new substance by breaking and forming new bonds, is correct.
Answer:
D. seems the most logical
The situation that is most similar in which a plant is moved to a higher concentration of salt in water is that of a freshwater plant being put into sea water.
Due to too much salt concentration, freshwater plants cannot survive on the ocean. If you ever see a plant wilting and am sure that this is because of soil imbalance, this can be solved by adding more water to even out the concentration.
The answer is b. Prop roots.
Mangroves are small trees and shrubs that live in the coastal zone. Mangrove trees must fight rough tides, huge waves, strong winds, and storms. One of adaptation is prop roots. The prop roots grow out the mangrove trunk, branches or other prop roots until they touch the ground. There they develop an underground root system. These roots serve as a support in the conditions characteristic for mangrove.
