Answer:
hope i helped but i think its b or d
Explanation:
Answer:
<h2>True</h2>
Explanation:
1 .Reverse transcriptase (RT) is an RNA-dependent DNA polymerase enzyme which makes DNA from RNA..
2. RT makes double-stranded DNA molecules from ssRNA ( single stranded RNA) molecule using it as a template.
3. Retroviruses like HIV contain Reverse transcpritase (RT) enzyme, which uses the RNA molecule as template and make DNA from it and after that, virus make multiple copies of itself.
4. Reverse transcriptase enzyme make DNA reverse transcrptionally from RNA the process known as RNA dependent DNA polymerase.
5. It was first discovered in retroviruses.
Answer:
Each protein with a specific structure and function
The unique three dimensional shape of proteins is based on several superimposed levels of structure
Explanation:
Proteins are essential nutrients for human and a vital source of fuel for building body tissues. They are made up of amino acids linked together by peptide bonds. These amino acids act as precursor to nucleic acids, hormones, immune, repair of tissues among others.
Proteins contain 20 amino acids which are the building block for proteins. These amino acids can be reformed to create millions of protein in human body in which each protein has specific structure and function.
The three dimensional arrangement of atoms in an amino acid chain is know as the protein structure. The precise shape formed determine the protein function.
Sulfa drugs, such as antibiotics that contain sulfonamides. Example: Some combination drugs such as Sulfamethoxazole-trimethoprim (Septra, Bactrim) and Erythromycin-sulfisoxazole contain sulfonamides. <span>

Answer: Electromagnetism
Explanation: Electromagnetism is one of the four fundamental forces (the other three are gravity, strong nuclear force and weak nuclear force.) It acts between all the particles having an electrical charge.
