Answer:
The correct answer to the question: When the pH of the extracellular fluid drops, the kidneys:____, would be: C: excrete fewer bicarbonate ions.
Explanation:
The pH of the human body, given by the extracellular fluid that flows and is contained in it, holds a narrow margin between 7.35 and 7.45. When hydrogens ions increase, and bicarbonate ions decrease, in any of these fluids, be it blood, CSF, or any other, then we known that a person´s body is going into acidosis because the pH level is dropping. However, when the scenario is the opposite, with more bicarbonate ions, than hydrogen ions, then we are talking of an alkalosis. In order for the body to restore its normal levels, it has a series of mechanisms that will ensure the reestablishment of balance. One such mechanism is the excretion of elements through the urine, by the kidneys. In a case of acidosis then, the correct procedure is that kidneys produce urine charged with the excess hydrogen atoms and re-uptakes bicarbonate ions that might have escaped while producing urine. The urine will become acidic then. This is why the answer is C.

Splinting, immobilization, or both are recommended for any suspected fracture (broken bone) or dislocation. A strong splint effectively reduces discomfort and helps to stop future damage. Splints can be purchased already manufactured or can be created using simple supplies.
One may, for instance, use a foam sleeping pad, boards, layers of cardboard, or branches. Bandanas, climbing webbing, shredded shirts, jeans, or other garments can be used as wrapping materials for the splint.
To secure the splint, these materials should fully encircle the affected extremity. However, they shouldn't be too tightly wrapped to restrict blood flow.

Answer:
Option (d).
Explanation:
Sales presentation is mainly done to sell any products to the customers. The sales man and woman should provide each and every detail to the customer and should convince them to buy their products.
As both Mr. and Mrs. Nunez wants to enroll. The signs of both the partner are required on the legal form. Mr. Nunez can only sign on his behalf and he needs to wake up the Mrs. Nunez to sign on the legal documents of the paper.
Thus, the correct answer is option (d).
Answer:
Taking into account that:
The flow velocity u of a fluid is a vector field
u = u (x, t)
What gives the velocity of a Fluid Plot at position x y time t.
q = || u ||
Now if the flow is continuous as it happens in the blood vessels then:
The flow of a fluid is said to be constant if it does not move over time, that is why the variant would be 0.
Explanation:
As for the pump with narrow vessels, there the area would be less, therefore the flow also and the flow velocity as well. Adding that the friction with the walls increases as it is narrower, thus generating an increase in pressure with the flow of the liquid.
So this is where we have to put emphasis on the biophysics branch that explains the following:
The Venturi effect is explained by the Bernoulli Principle and the principle of continuity of mass. If the flow rate of a fluid is constant but the section decreases, the speed necessarily increases after crossing this section. By the theorem of conservation of mechanical energy, if the kinetic energy increases, the energy determined by the value of pressure necessarily decreases.
Indeed, according to Bernoulli's principle:
P 1 + 21 ρv 12 + ρgh 1 = P 2 + 21 ρv 22 + ρgh 2
