You need to discuss the different roles of different types of RNA:
mRNA allows the creation of a primary transcript of DNA which can be taken from the nucleus to the ribosome.
rRNA makes up the structure of the ribosome, where translation, the synthesis of a polypeptide chain, occurs.
tRNA transports amino acids to the ribosome and matches the RNA codon with its anticodon, and joins the amino acid to the polypeptide chain that is being created.
The answer is B and that is the same reason that everything stays on the Earth because it has very strong gravity.
Prenatal medical procedure in which high frequency sound waves are directed into a pregnant woman's abdomen is called ultrasound sonography.
Ultrasound imaging or sonography is often used in medicine as the nondestructive procedure to visualize muscles and many internal organs as well as fetuses during routine and emergency prenatal care..
Answer:
Your answers are correct or at least from the information I know and read super sorry if wrong but everything checks out!
This question had choices. These are the missing choices.
A) Scientists made careful observations of behavioral patterns.
B) The DNA mutation rates for both species was calculated and compared.
C) Scientists made a detailed analysis of the fossilized bones of each species.
D) The enzyme activity of each species was studied to determine similarities in metabolism.
My answer:
C) Scientists made a detailed analysis of the fossilized bones of each species.
This determination is the only feasible thing to do since dinosaurs are long dead and choices A, B, and D requires the subjects to be alive.
