Explanation:
when you perform electrolysis on water, you are turning water into hydrogen and oxygen gas, that's where the bubbles come from. ... You turned water into water vapor. The main difference is that electrolysis is a chemical change and boiling is a physical change.
When water is boiled, it undergoes a physical change, not a chemical change. The molecules of water don't break apart into hydrogen and oxygen.
One of the best electrolytes for water electrolysis is sulphuric acid (H2SO4). When it ionises in water, it breaks down, depending on its concentration, to either H+ and HSO4- or 2 H+ and SO4- -.
Answer: 62.9%
Explanation:
Figure one is not available so I cannot answer the first part of the question.
The second part however, has the relevant information required.
The percentage of large animals eaten by lions from the total amount of biomass eaten by lions is:
= Weight of large animals / Total weight of animals eaten by lions * 100%
= 110,000 / 175,000 * 100%
= 62.9%
Answer: A) Evolution or B) Natural Selection
Explanation: The fur of these bunnies change color with the seasons in order to better blend into their environment. This is an example of a species evolving to better survive!
However, this could also happen as a result of natural selection. Those who were able to better survive would pass on their genes for fur that changes with the seasons.
Answer:
B) hypertension and bradycardia.
Explanation:
Autonomic dysreflexia is a syndrome which is characterised by the sudden rise in the blood pressure of the human. The disease is common in the people with a higher level of spinal cord injuries above the T6 level.
The condition occurs when some external stimuli like pain or irritant activate the involuntary response in the body which cause the blood pressure to rise (hypertension). This leads to the slowdown of the heartbeat (bradycardia) to restore the blood pressure but the body cannot restore the blood pressure due to the damage in the spinal cord.
Thus, Option-B is the correct answer.
