What is base pairing? (and Chargaff's rule)?
Answer:
A base pair (bp) is a fundamental unit of double-stranded nucleic acids consisting of two nucleobases bound to each other by hydrogen bonds. They form the building blocks of the DNA double helix and contribute to the folded structure of both DNA and RNA. The rules of base pairing (or nucleotide pairing) are: A with T: the purine adenine (A) always pairs with the pyrimidine thymine (T) C with G: the pyrimidine cytosine (C) always pairs with the purine guanine (G).
Explanation:
Chargaff's rules state that DNA from any species of any organism should have a 1:1 stoichiometric ratio of pyrimidine and purine bases and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine. This pattern is found in both strands of the DNA.

The children in a middle school classroom are all exposed to chicken pox one week. Among these students are John, who had chicken pox when he was much younger, and Sara, who has never had chicken pox. Which student do you expect would be less likely to become ill with chicken pox following this exposure and why? (5 points) John: he has naturally acquired active immunity to chicken pox from his previous exposure. Sara: she has naturally acquired passive immunity to chicken pox from exposure to other students. John: the pathogens that cause chicken pox will no longer be able to enter his body. Sara: since she has not suffered from chicken pox, her immune system is probably stronger than Johns.
Answer:
John: he has naturally acquired active immunity to chicken pox from previous exposure.
Explanation:
Your body naturally has some immunity to things that aren't you, but when you get sick with a specific pathogen, your body begins to make antibodies that specifically recognize that pathogen. Each antibody only recognizes one pathogen, and it floats around waiting to find it again so it can tell your body to kill it before you get sick again. This is why we become immune to chicken pox; after the first time you beat it, your body has the labeled antibodies and it can quickly destroy the pathogen before you get sick again.
Answer:
John: he has naturally acquired active immunity to chicken pox from his previous exposure.

many cellular functions can be compared with functions that occur in organisms. which is not a function that both cell and an organism share. A stores waste material for removal B provides structure and support C learn behaviors that aid in survival D conversion of nutrients into usable energy
Answer:
learn behaviors that aid in survival
Explanation:
learn behaviors that aid in survival is not a function that both a cell and organism share because a cell is a basic unit of life and contains some organelles that perform little functions while an organism comprises of many specialised cells that work to perform similar functions. An organism have central nervous system which comprises of brain and spinal cord. Organisms learn new behavior and acquire cognitive skills through the brain development. The brain and spinal cord receive electrical impulses sent from neurons and interpret it to meaningful information.
Learning behaviors that aid in survival is not a function that both cell and an organism share.
LEVEL OF ORGANIZATION:The cell is the basic and functional unit of living organisms. This means that the cell harbors the functional characteristics of living organism.
However, some functions are performed both at the cellular and organism level. Some of these functions include;
