Answer:
Plants and animals are pH sensitive. The growth of plants is dependent on the nature of the soil. If the pH of the soil is greater than 7 and is alkaline, then the plants cannot grow in the soil.
Explanation:
Answer:
from the small intestine (RE = retinyl ester; ROH = ret- inol. CM = chylomicron remnant). is split at least one intact molecule of retinol, retinal.
Greenhouse gases released from the burning of fossil fuels are responsible for global warming.
<h3>What is the atmosphere?</h3>
The atmosphere is the region of region of the planet above its surface area where gases envelop the planet.
Based on the effect of greenhouse gases on global warming;
- Planet A has a higher surface temperature due to the higher amount of carbon dioxide in the atmosphere since carbon dioxide is a greenhouse gas.
- Methane is the main constituent of natural gas. Humans increase the contribute to increase in methane gas by raising cattle,
- Pollutants come from both natural sources and human activities.
- Sulfur Dioxide is produced by the combustion of fuels in automobiles. Once in the atmosphere, it combine with water to form acid precipitation.
- Nitrogen and oxygen do not contribute to the greenhouse effect because they are made up of 2 atom molecules that are bound tightly so they CANNOT vibrate to absorb energy.
- Greenhouse gases contribute to global warming by absorbing infrared energy that reflects off Earth's surface and reemitting the energy in all directions. This keeps the infrared energy close to the Earth's surface.
- Most of the greenhouse gases produced come from burning fossil fuels in factories, ships, cars, trains.
Therefore, pollutants such as greenhouse gases are responsible for global warming.

Answer:Gained, Lost , Shared
Explanation:
The oxidation state tells you how many electrons an atom has GAINED.................. , LOST....................... , or SHARED........................ , in forming a compound.
Oxidation state is defined as the the total number of electrons that an atom gains or loses when forming a chemical bond with another atom.
----To form an ionic bond for example in NaCl, Na, with 11 electrons and one valence electron in its outermost shell donates or lose that valence electron to Chlorine with 17 electron and 7 in its outermost shell. Therefore Sodium, Na acquires the +1 oxidaton state to become stable and Chlorine acquires the -1 oxidation state to become stable forming the NaCl compound.
To form a covalent compound, There must be sharing of electrons between atoms.For example, in PCl3, The phosphorous atom with atomic number 15 shares its three unpaired electrons with the single valence electrons of three chlorine atoms. making the four molecules to attain stability with Phosphorous having +3 and the chlorine atoms having -1 oxidation states
