Answer:
animals are the only organisms that compete for resources
Explanation:
this is due to the fact that plants take up resources passively, a method which doesn't require them to waste any energy, however in the case of resources, is not very effective. suppose there was a bit of water scarcity in your area, and a plant and you both need water for survival. obviously, the plant cant possibly do anything to receive these resources, as it is just a plant. its survival is based merely on the chance that you pour water into it. this is not the case for animals, which, like us, actively collect and gather resources, and use them to our advantage. therefore, animals are the only animals that compete for resources
I think you forgot to attach the statements along with the question. I am answering the question based on my knowledge and research. "It's evolution within a single population" is the one statement that <span>is true about microevolution. I hope that this is the answer that has come to your great help.</span>
Answer: Meiosis
Explanation:
Meiosis in humans is a division process that takes us from a diploid cell—one with two sets of chromosomes—to haploid cells—ones with a single set of chromosomes.
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.
