4.) mumps or Mononucleosis
Answer:
Explanation:
Given that d = 0.11cm = 0.0011m, l = 2.2m, extension = 1.24cm = 0.0124m, mass = 34kg
force = 34 x 9.81 = 333.54N, Area = Pi x d²/4 = 3.142 x 0.0011^2/4 = 9.505x10^-7m²
Calculate the stress = Force/Area = 333.54N / 9.505x10^-7m²
= 350926661.4N/m²
calculate the strain = extension/original length
= 0.0124 / 2.2 = 0.00563
Young modulus of elasticity = Stress/Strain = 350926661.4N/m² / 0.00563
= 6.2332 x 10^10Pa
Bacterial cell membranes do not have cholesterol. The principal function of the cell membrane is to regulate the substances that enter the cell and the substances that move out of the cell. Cholesterol is a fat like substance that is found in all human cells; it is an important constituent of the cell membrane and it enhances the fluidity of the cell. Bacterial have plasma membrane but the membrane do not contain cholesterol.
Those are antidepressant drugs that
increase the level of neurotransmitters. Selective serotonin reuptake inhibitors (SSRIs) affect the process of neurotransmitters’ reabsorption back into nerve cells. This inhibitor prevents reuptake of serotonin and instead of that, the serotonin stays in the gap between the nerves-synapse.
Tricyclics are antidepressants that block the reabsorption of neurotransmitters, in this case, serotonin, and epinephrine. As a result, these chemicals are released into a synapse.
<span>Monoamine oxidase inhibitors (MAOIs) block the enzyme monoamine oxidase which breaks down serotonin, epinephrine, and dopamine. As a result, the levels of those neurotransmitters are increased.</span>
