Answer:
The weight of an object is known to occur from the gravitational pull of the earth. Hence, for weight to occur, a certain force should be there. The more the gravitational pull the more the force.
According to this information, the planet made of iron will have high gravitational pull. Hence, the weight of an organism will be more on a planet made of iron rather than a planet made of cheese.
Answer:
B
Explanation:
The Ames test is a bacteriological technique commonly used to determine if a particular chemical or substance can cause mutations. To achieve this, researchers use bacteria (commonly <em>Salmonella typhimurium</em>) as this bacteria strain is unable to grow in a medium that does not contain histidine (a very important amino acid in the biosynthesis of proteins). If the studied substance is able to cause mutations, bacteria will mutate, and they will be able to grow on that particular media even if they don’t have histidine for their metabolism. Therefore, if there are colonies growing, the chemical being tested is mutagenic.
I hope this clarify your inquiry.
