c. stays the same
b. decreases
d. both b and c
Answer:
Option C, stays the same
Explanation:
Heat flow by vibrating the molecules in any medium. Therefore, some medium is essential for heat transfer and hence no heat flows across an insulated vacuum can. Without any medium, heat transfer is stopped which means that neither the heat from outside environment can flow into the can nor it can flow from the can into the external environment.
Hence, the heat contained within the can shall remain the same.
Thus, option C is correct
The correct answer is A. They ensure that the ecosystem is not stripped entirely of its vegetation
Answer:
A
Explanation:
Answer:nonliving air is a gas
B-alcohol fermentation
C-citric acid cycle
D-electron transport chain
Answer:
The correct answer would be B-alcohol fermentation.
Alcohol fermentation or ethanol fermentation is a type of anaerobic respiration by which organism (such as yeast) convert sugar such as glucose, sucrose et cetera into ethanol and carbon dioxide in order to produce energy.
First, glucose is converted into 2 molecules of pyruvate by the process of glycolysis. It leads to the formation of 2 molecules of ATP (adenosine triphosphate) and 2 molecules of NADH.
Then, two molecules of pyruvate are converted into two molecules of acetaldehyde with the help of enzyme pyruvate decarboxylase. Two molecules of carbon dioxide are released as a byproduct.
Lastly, two molecules of acetaldehyde are converted into two molecules of ethanol with the help of enzyme alcohol dehydrogenase. It consumes two NADH and regenerates two NAD⁺ lost during the process of glycolysis.
Hence, the net gain of alcohol fermentation is two ATP.
Thus, we can say that ethanol is produced during alcohol fermentation.
During alcohol fermentation ethanol is produced.
Alcohol fermentation involves the break down of sugars in organisms such as yeast to form ethanol or alcohol, carbon dioxide and release energy.

If a geneticist is studying the allele combinations at a cellular level, they are studying an organism's genotype. Therefore, the correct answer is a) Genotype.
Water exists in all the statesofmatter which are the solid, liquid, and gaseous states.
Water is known to exist in three different physicalstates. These are the solid state as ice, the liquid state as water itself, and the gaseous state as water vapors.
Under the conditions of standard temperature and pressure, the freezing point of water is zero degrees Celsius. At this temperature, water starts to freeze and attains a solid form which is in the form of ice. The density of ice is lower than the density of water because of the fixed intermolecular distances in ice.
Under the conditions of standard pressure and temperature, water exists in liquid form between temperature ranges of zero to a hundred degrees Celsius. Liquidwater is essential for all organisms. It functions as a universal solvent.
At a temperature above hundred degrees Celsius, the intermolecular integrity between the molecules of water starts to decrease and ultimately breaks completely. In these conditions, the water turns into vapors.
Therefore, water exists in all the states of matter which are solid, liquid, and gaseous states.
