Answer: The given statement is true.
Explanation:
When there occurs changes in organic substrates with the help of enzyme action then this process is known as fermentation. This process results in the formation of alcohols.
For example, process of fermentation occurs in yogurt, pickles, beers, wine etc.
Also equation for alcoholic fermentation is as follows.
Therefore, we can conclude that the given statement process by which complex compounds are broken down by enzymes and by which many organic alcohols are formed is called fermentation, is true.
D) Hydrochloric acid
B) oxygen, glucose
C) carbon dioxide, oxygen
D) oxygen, carbon dioxide
The answer is C) carbon dioxide, oxygen.
Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
So lets eliminate some answers:
Oxygen can not convert itself to glucose and plants don't take in oxygen so this answer is automatically eliminated
Plants take in carbon dioxide and convert it to oxygen basically how humans breath but inverted, not the other way around.
Glucose naturally is not found in the atmosphere in the first place so if a plant were to survive is would have to be in a glucose enriched environment which is very uncommon meaning it would be very rare to be a living functional plant that can photosynthesize. So this is checked off the list!
So we are now left with one sentence that would make sense
Plants take in carbon dioxide meaning the first section of this answer is right and they release oxygen which is also correct therefore this statement is valid and is the correct answer
Hope this helped (:

Answer:
Combustion reactions must have oxygen as a reactant. Note that the water that is produced is in the gas rather than the liquid state because of the high temperatures that accompany a combustion reaction.

(2) The entropy of the LiBr(aq) is less than the entropy of the water.
(3) The dissolving of the LiBr(s) in water is an endothermic process.
(4) The dissolving of the LiBr(s) in water is an exothermic process.
The statement best explains why the thermometer reading initially increases when LiBr(s) is dissolved in the water is the dissolving of the LiBr(s) in water is an exothermic process.
A thermometer is an instrument that is used to measure the temperature of an object.
An exothermic process is in which the heat and energy is released in the outer system.
Thus, the correct option is (4) The dissolving of the LiBr(s) in water is an exothermic process.

(2) They have the same masses and different charges.
(3) They have different masses and the same charges.
(4) They have different masses and different charges.
Protons and electrons differ in both their masses and their charges. Protons have a larger mass and positive charge whereas electrons have a smaller mass and negative charge.
The correct answer to your question about proton and electron characteristics is option 4: They have different masses and different charges. To elaborate, a proton is a positive-charged particle found in an atom's nucleus with a relatively high mass. On the other hand, an electron is a negative-charged particle circling the nucleus, with a mass nearly 2000 times lighter than a proton. Thus, they both differ in their masses and in their charges.

The statement that is true about a proton and an electron is that they have different masses and different charges, which corresponds to option (4).
The correct statement about a proton and an electron is that they have different masses and different charges. Therefore, the answer to your question is (4) They have different masses and different charges.
Protons are subatomic particles found in the nucleus of an atom and have a positive electric charge. On the other hand, electrons are subatomic particles that orbit the nucleus of an atom and have a negative electric charge. The mass of a proton is significantly larger than the mass of an electron.
A proton's mass is about 1.6726 x 10-27 kilograms, which is nearly 1836 times the mass of an electron, which is approximately 9.109 x 10-31 kilograms.

b. no ability to produce rain.
c. particles made of ice crystals.
d. its base at or near the ground
Answer: d. Its base at or near the ground.
Explanation:
Fog is a visible weather condition in which the tiny droplets of water present in the atmosphere come together and which forms a thick cloud which lies close to the surface of the ground (land) or above the sea surface. Fog cuts the visibility down to one kilometers, it makes it difficult to observe the things through it. The fog is influenced by several factors such as wind conditions, nearby water bodies, and topography.
Fog is a cloud that has its base at or near the ground. The answer is letter D. Fog results when atmospheric water vapor condenses to the extent that the new forms, water droplets or ice crystals, become visible. Saturation of the air and sufficient condensation nuclei are ordinarily prerequisites for the formation of fog. One of the great hazards associated with fog is a lack of visibility.
