There is no graph but the reason people who have aids cant fight it off is because it is an immune disease it quickly weakens the immune system and makes a persons body too weak to fight anything off.
Answer:
B.
Explanation:
According to kinetic molecular theory, gas molecules are moving around very rapidly in random directions; they do not line up next to each other like a solid.
Answer:
1,2 and 4 are correct
Explanation:
Enzymes that show cooperativity are defined as Allosteric enzymes. This cooperativity is of several types.
1) homotropic/homoallestery - positive cooperation
2) heterotropic/heteroallestery - negative cooperation
Activity of allosteric enzymes is regulated by other molecules (effector molecules)
Hence, statement 1 and 2 are correct.
Binding curve of allosteric enzymes:
For cooperative binding, binding curve is Sigmoidal curve
For non cooperative binding, binding curve is Hyperboilc curve.
Hence, statement 3 is wrong.
Allosteric enzymes have multiple active sites.
Allosteric enzymes are often multi sub unit proteins.
Hence, statement 4 is correct.
Answer:
b
Explanation fission reaction the mass defect is negative
The reaction between the lemonade powder and water occurs on the surface of the powder particles. By moving through the water, the lemonade powder particles comes into contact with water molecules.<span> Stirring induces the lemonade powder to move faster through the water. It actually increases the kinetic energy of the lemonade powder and causes them to move rapidly. The bigger the kinetic energy is, more particles can come into contact with more water molecules and, thus, the lemonade powder dissolves faster.</span>
