Answer:
Total 495 liters of natural oil are needed.
Explanation:
It is given that Petrolyn motor oil is a combination of natural oil and synthetic oil. It contains 5 liters of natural oil for every 3 liters of synthetic oil.
It means the ratio of natural oil and synthetic oil is
Let in order to make 792 liters of Petrolyn oil he needs x liters of natural oil.
It means the ratio of natural oil and synthetic oil is
Equate both ratios,

On cross multiplication we get


Divide both sides by 8.


Therefore total 495 liters of natural oil are needed.
Answer: I believe the right answer is B) atmospheric nitrogen→bacteria→plants→animals. I'm pretty sure!
Sorry for answering a bit late, hope that helps! :-)
No because Antarctica is ice
Answer:
Sperm undergo more mitotic cellular divisions than egg and therefore have a higher risk of developing a spontaneous mutation.
Explanation:
As you have seen in the question above, lycanthropy is a mutation that is more likely to be established as the supply of male gametes comes from older men. This is because sperm undergo more mitotic cell divisions than eggs, and therefore are at greater risk of developing a spontaneous mutation.
In order for you to understand this, you need to know that eggs (which are female gametes) are produced at once in a woman's body. Thus, cell division is limited and therefore the opportunity for spontaneous mutations to occur is also limited. However, men produce sperm from adolescence to death, creating the need for countless cell divisions, which can develop genetic errors that create spontaneous mutations in gametes.
Answer:
A) heritable traits cannot be altered by experience
Explanation:
This is because the Darwinist believe that heritable traits were acquired from previous generation not from practise or learning which may develop to experience with time.He believed that certain selective pressures must have acted or selected these organisms to possess these heritable characteristics, and can not be altered by experience whicg is acquired with age.
He should conclude therefore that variation in the organisms which possess these characteristics should be the main factor which gives them selective advantages to inherit these traits compare to others in this same surrounding environment Therefore he will discard the influence of environment.
