b. False

Answer 1
Answer:

Answer:

The answer to the question: The membrane potential seeks the equilibrium potential of the ion whose permeability is dominant, would be, True.

Explanation:

When a cell needs to prepare to activate itself, or start what is known as an action potential, there needs to be a change in the polarity that is constant over the cell membrance. Usually, this polarity tends to be primarily negative on the inside thanks to the anions, and positive on the extracellular side, thanks to the concentration, particularly of sodium ions. In general, and without stimulus, this resting membrane will not activate or generate anything. However, when the cell activates, several channels, both leakage and gated, will activate to allow the two most important ions, sodium and potassium, to leak in and out of the cell to generate an electrical gradient. In order to restore this, and return to resting, the cell´s membrane must restore its potential, and thus, it will activate the channels of the dominant ion, to restore the balance. In fact, normally, there are leakage potassium channels in the cell membrane that allow potassium to leak out of the cell, helping to maintain the negativity of the cytoplasm, and the stability.

Why do many cancer patients undergoing chemotherapy lose their hair? A. The cancerous cells take up too much of the body's available energy, leaving none available for hair growth
B. Most types of cancer start in the hair follicles
C. Chemotherapy treatments block the synthesis of keratin, the primary protein
component of hair
D. Chemotherapy treatments disrupt meiosis
E. Chemotherapy treatments stop cell division, and therefore have the most pronounced side effects on tissues that normally have the highest rates of cell division, such as hair

Answers

Answer:

Answer is E.

Explanation:

During chemotherapy, the medications are so strong and powerful that it target and stop all cells that undergo fast rate of division. Hair tissues are one of the fast dividing cells in the body so chemothrapic drugs stop its division resulting in hair fall.

b. draws the angle of the mouth up as in smiling
c. elevates and retracts the mandible
d. Temporalis does all of the above actions

Answers

Answer:

The correct option is : c. elevates and retracts the mandible

Explanation:

The temporalis muscle or the temporal muscle, is one of the muscles that are involved in the process of mastication or chewing. It is a fan-shaped and broad muscle which belongs to the group of chewing – lower mandible.

Mandible is the lower jaw or the jawbone, is a very strong and the largest bone in the human face.

The main function of the temporalis muscle is the elevation and the refraction of the mandible.

Which of the following not only flexes the hip but also extends the knee joint? a. satorius
b. psoas major
c. tenor fasciae latae
d. gracilis

Answers

Answer:

a. satorius

Explanation:

The sartorius muscle is a two-joint muscle that moves both the hip and knee joints. Although anatomically considered a thigh extensor, its contraction actually causes a flexion of the hip joint. This is due to its location in the anterior (extensor) compartment of the thigh. Additionally, it is involved in abduction and external rotation of the hip joint.

In the knee joint, it forces an internal flexion and rotation. Flexion movement is the result of tendon insertion into the knee joint behind the flexor-extensor axis. When all five movements are performed simultaneously the legs cross in meditation position. Thus, the muscle is most easily palpable in this position.
