Answer: B. beta
Explanation:
Sickle cell anemia is a inherited disorder which occur due to mutation of gene responsible for synthesis of hemoglobin protein. Typically the gene which is responsible for synthesis of beta-globin protein which make the beta chains in the hemoglobin is affected by the mutation. As a result of this the red blood cells acquire a shape of sickle rather than round. Pain, cold, stress, dehydration and illness are the symptoms associated with this disorder.
Answer:
1.292 M
Explanation:
<em>In order to calculate the concentration of H2SO4, we need to get the balanced equation of reaction first;</em>
Using the formula:
CaVa/CbVb = na/nb
where Ca = concentration of acid, Va = volume of acid, Cb = concentration of base, Vb = volume of base, na = number of moles of acid, and nb = number of moles of base.
In this case, Ca =?, Va = 10.00 ml, Cb = 0.777, Vb = 33.25 ml, na = 1, nb = 2
Ca = CbVbna/Vanb = 0.777 x 33.25 x 1/10 x 2
Ca = 1.292 M
Hence, the concentration of H2SO4 is 1.292 M
The activation energy of a given chemical reaction is the minimum required amount of energy needed to start the reaction, for the reaction to start. All reactions have an activation energy, even spontaneous ones, ones that do occur spontaneously. It is a thermodynamic barrier that separates the amount of energy reactant molecules must possess to ultimately react with each other to produce the respective products.
Answer:
Over active recticular formation
Explanation:
It diffuse projections enable the systems to have multiple actions, as might be expected of arousal systems.
