ANSWER FOR QUESTION 3: The answer would be B.) because work or energy, is equal to the work done by a force, like the ball.
ANSWER FOR QUESTION 4: The answer would be D.) because when a ball roles down a hill the work to push that ball can transfer energy between the ball or other objects and cause the change in the total amount of energy used.
ANSWER FOR QUESTION 5: The answer is mechanical, because both physical and constant, kenitic and potential.
Answer:
C) it is necessary for the survival of the individual.
Explanation:
Sexual reproduction is rarely, if ever, necessary for the individual. This is not a reason for its importance. However, while not important for the individual, sexual reproduction is important for the species. It allows genetic variability among offspring, as well as mutations. This ensures that not all members of a species are the same, and in this way, they have a better chance of surviving. Moreover, it allows for offspring to be produced at a faster rate.
The essential amino acids cannot be produced in the human body and hence these amino acids have to be obtained through the diet. Hence these amino acids have this characteristic that these cannot be produced in the human body and have to be obtained through diet this makes them essential. Hence those nine amino acids are considered as the essential amino acids.

Answer:
Human genome has various replicons.
Explanation:
A replicon which is a unit of DNA, has potential to get replicated independently. So, the DNA replication occurs simultaneously at various replicons as a result of which human genome takes much less time than estimated to get replicated .
In contrast to this, prokaryotes like E.coli have only one origin of replication and thus one replicon due to which replication is restricted to once per cell cycle.
