Which of the following situations correctly illustrates the all or non principle? 

select one: 

a.) A smaller voltage change will result in a smaller nerve impulse 

b.) A faster impulse can be generated with a voltage change that is greater than the threshold potential.

c.) A stronger impulse can be generated by increasing the number of open voltage-gated sodium channels during depolarization.

d.) A greater voltage change and a smaller voltage change will result in the same action potential as long as the threshold potential has been reached.

Which of the following is NOT a reason why a reflex arc is faster than a normal nerve transmission 

select one: 

a.) a reflex arc does not send information to the brain to be processed 

b.) A reflex arc does not involve neurotransmitters 

c.) A reflex arc stimulates the motor neurons for an immediate reaction 

d.) A reflex arc involves fewer neurons 

A woman taking birth controls pills would expect to have 

select one:

a.) Higher than normal FSH and LH levels due to fewer negative feedback messages being sent to the ovaries 

b.) Lower than normal FSH and LH levels due to more neagtive feedback messages being sent the pituitary gland 

c.) Higher than normal FSH and LH levels due to fewer negative feedback messages being sent to the pituitary gland 

 d.) Lower than normal FSH and LH levels due to more neagtive feedback messages being sent the ovaries 

PLEASE ANSWER AND HELP! IM VERY CONFUSED ON THIS QUESTION:) 

A famous fractal called the Sierpinski Triangle starts with one black triangle. The triangle is then cut into four equal pieces, and the three outer triangles are coloured black and the inner triangle is white. Each of the three black triangles is again divided into four equal triangles, and the three outer triangles are shaded black.

a. Suppose the area of the first triangle is 100 cm2. Determine the black shaded area in the second triangle. Do the same for the third triangle.

b) Write the general term describing the shaded area of the nth Sierpinski Triangle.

c)Suppose the diagram continued on. What total area would be shaded in the first ten Sierpinski Triangles? Round to the nearest whole number.

d) Suppose the fractal continued forever. Determine the total area shaded in all the triangles, if possible.

Oxytocin is a reproductive hormone associated with parturition and lactation. A research study examined the blood serum levels of oxytocin in patients who have Type 2 diabetes and those with normal blood glucose levels. Each group was then subdivided into normal weight patients and obese patients. The levels of oxytocin were found to be lower in the obese patients with Type 2 diabetes than in the normal weight patients with normal blood glucose levels.Select the possible side effects that a lower level of oxytocin may have on a patient.

Determine t7 of a geometric sequence, where r = 5 and t1 = 2

Using Hess's Law, the enthalpy of reaction for the following equation:

2C2H4O(l)+2H2O(l)→22C2H4O(l) + 2H2O(l) → 2C2H6O(l) + O2(g)

C2H6O(l) + 3O2(g) → 2CO2(g) + 3H2O(l) ΔH = -685.5 kJ

C2H4O(l) + 5/2O2(g) → 2CO2(g) + 2H2O(l) ΔH = -583.5 kJ
