Answer:
For a couple of decades, biologists knew the nucleus contained DNA and proteins. The prevailing opinion was that the genetic material was proteins, and not DNA. The reason for this belief was that proteins are more complex than DNA. This is because: <u>proteins have a greater variety of three-dimensional forms than does DNA.</u>
Explanation:
Protiens have a greater variety of three dimensional forms than does the DNA
Protiens contain one or more polypeptides which are usually arranged in one of the following structures :
1)Primary structure
2) Secondary structure
3) Tertiary structure
4) Quaternary structure
These structures are maintained by Hydrogen bonding , Hydrophobic interactions , Disulphide bonds and ionic bonds )
DNA on the other hand is a double stranded molecule containing only hydrogen bonds between the nitrogenous bases and the covalent bonds within nucleotides. It is much simpler than protiens.
Answer:
b. can no longer undergo cell division.
Explanation:
Terminally differentiated cells are those cells completely specialized in their functions that have lost their ability to proliferate. They are cells that have a unique, very specific, function, whereas undifferentiated cells do not have specialized functions that serve to replace old and dead cells. Examples of terminally differentiated cells include skin cells derived from epithelial stem cells, red blood cells and white blood cells generated from hematopoietic stem cells, etc.

An organism's genotype is a major (the largest by far for morphology) influencing factor in the development of its phenotype, but it is not the only one. Even two organisms with identical genotypes normally differ in their phenotypes. One experiences this in everyday life with monozygous (i.e. identical) twins.
so ATP is adenine triphosphate
it has 3 phosphate groups, hence the 'tri'
it has nitrogen containing carbon rings
and it also had a carbon ring containing OH groups
i can't draw it on here but if you google the structure hopefully my explanation will make more sense
