The order in which the amino-acids are placed within the polypeptide determines the tertiary structure and therefore the function of the given protein. Amino acids have different functional groups like methyl(CH3), phenyl(C6H5). Those functional groups can interact with molecules like glucose determining reactions, the proteins that catalyze reactions are called enzymes. Other functional groups of amino acids can be the sulfate groups. For example, insulin has 2 polypeptide chains(Chain A has 21 amino acids, and chain B, 30). Between the two polypeptide chains, 2 disulfide bonds form altering its shape.
The level of organization is plants, coral and water. Water came first.
It would require that the csf acts exclusively on : Myeloblasts
myeloblasts is a unipotent stem cell, which differentiate into one of the effectors of the granulocyte series.
It is commonly found in bone marrow.
Early in mitosis, during prophase and prometaphase, the nucleus, nucleolus and nuclear envelope begin to dissolve in preparation for cell division. During telophase, which is the final stage in mitosis,, there is a reversal of effects of prophase and prometaphase; nucleus, nucleolus and nuclear envelope are again formed.
Answer:Valves stop blood flowing backwards
Explanation: Valve are flags of tissue that control the direction of the blood in our heart.,it prevent the backwards flow of blood. valves regulate blood from flowing back into the atria.The right and left atrio-ventricular valves prevent blood from flowing backwards into atria. When the ventricle is full,the valve prevent backwards flow of blood.
