 glucose solution of density 1050 kg/m3 is transferred from a collapsible bag through a tube and syringe into the vein of a pers

on's arm. The pressure in the arm exceeds the atmospheric pressure by 1400 N/m2.
How high above the arm must the top of the liquid in the bottle be so that the pressure in the glucose solution at the needle exceeds the pressure of the blood in the arm? Ignore the pressure drop across the needle and tubing due to viscous forces.

Answer:

0.136 meter

Explanation:

The following equation will be used to solve this question -

P_{atm} + \frac{1}{2} (rho)v^2 + (rho)gh = P_{inject} + \frac{1}{2}(rho)v_{inject}^2 + (rho)gh_{injec}

P_{atm} -P_{injec} = 1400\frac{N}{m^{2} }

Velocity is zero.

Removing out the nullified terms from the above equation, we get -

(rho)gh = P_{injec}\\1050 * 9.8 * h = 1400\\h = \frac{1400}{1050*9.8} \\h = 0.136 meter

Hence,  top of the liquid in the bottle must be at a height of 0.136 meter.

Which best describes the limits of science?
vichka [17]

A. Science cannot answer philosophical questions. Philosophical questions could be described as rheoretical questions, such as "what is the purpose of life?" These questions' answers can very from person to person. Science answers questions such as "what is the boiling point of water?", or "what is the chemical structure of water? These are both questions that have the same answer, no matter who is asking them. You just have to have the ability to accurately measure and observe the things involved, or in this case, the temperature of the water when it starts to boil or whe different atoms in the water.

Let's examine the other questions.

B. science can answer only mathematical questions. As you saw in the explanation above, science can also answer other questions, as long as they have a definite answer that we can accurately measure.

C.Science can answer any questions. Again, we have already saw that science cannot answer philosophical questions, so science cannot answer any question.

D. Science can answer any difficult questions. As with the example of the chemical stucture of water, we can answer difficult questions with science. This may seem simple to you, but it would be very difficult if it was not already known!

g Electron flow down the electron-transport chain leads to the transport of proteins: Group of answer choices from the matrix to
guajiro [1.7K]

Answer:

from the intermembrane space to the matrix

Explanation:

In the electron transport chain (ETC), electrons flow from one protein complex to another. However, as this electrons are transfered, protons (H+) is built up from the intermembrane space of the mitochondria to the mitochondrial matrix.

Hence, according to this question, a proton gradient is formed when hydrogen ions (H+) are moving from the intermembrane space to the matrix of the mitochondrial.

Define the term excretion.
Luba_88 [7]

Answer:

Excretion is a process in which metabolic waste is eliminated from an organism. In vertebrates this is primarily carried out by the lungs, kidneys, and skin.

Carbon dioxide

The liver regulates most chemical levels in the blood and excretes a product called bile. This helps carry away waste products from the liver. All the blood leaving the stomach and intestines passes through the liver. The liver processes this blood and breaks down, balances, and creates the nutrients and also metabolizes drugs into forms that are easier to use for the rest of the body or that are nontoxic.

p/s: pls vote if u find it's useful :3 thank youuu
