Answer:
The cells that make up the digestive, muscular, skeletal, reproductive, and excretory systems all need oxygen from the respiratory system to function, and the cells of the respiratory system as well as all the other system bneed nutrients and must get rid of metabolic wastes.
Explanation:
Answer:
(e)
Explanation:
Transmembrane protein are proteins that are firmly associated with membranes because it is integrated along the length of bilayer lipid membrane. This kind of protein is made up of two kinds of amino acid, hydrophilic or polar amino acid and hydrophobic or non polar amino acid. while peripheral protein loosely associated with membrane, they are present on the surface which means they are not integrated in to the cell membrane and facing intercellular fluid. this is why it contains only hydrophilic amino acid.
The primary amino acid sequence contains hydrophobic amino acid which identifies the protein as transmembrane protein. These amino acid are methionine (Met), leucine(Leu), valine(Val), glycine(Gly), tryptophan(Trp), isoleucine(Ile), phenylalanine(Phe), proline(Pro) and alanine(Ala)
From the question you can immediately infer that it's either B or D, as A and C basically mean the same thing and it isn't anything related to a microscope. I can tell you now that you don't need an electron microscope to see cells, they're only required for the atomic level.
Therefore, the answer is B, as you can't see cells without a microscope but you only need a light microscope, not an electron microscope.
Answer:
NO
Explanation:
No, the two carbon atoms that are lost from the TCA in the form of carbon dioxide didn’t come from the acetyl CoA. Isotope labeling analysis has shown that the two carbons of acetyl CoA can be lost in the second or third run of the cycle but not in the first run.
