All of the cells in the body need oxygen. Hemoglobin molecules in red blood cells transport oxygen through the bloodstream. Oxyg

en is loaded onto hemoglobin molecules in the lungs and unloaded from the hemoglobin molecules in the tissues.
What drives the unloading of oxygen from hemoglobin molecules in the tissues?

A. the low partial pressure of oxygen in the tissues
B. the high partial pressure of carbon dioxide in the tissues
C. the low partial pressure of carbon dioxide in the tissues

Answer: Option B) the high partial pressure of carbon dioxide in the tissues.

Explanation:

The high concentration of oxygen in the alveoli of the lungs unloads H+ and carbon dioxide (CO2) from the hemoglobin, just as the high concentration of H+ and CO2 in active tissues unloads Oxygen from hemoglobin molecules.

(2pts) During the Purification of Lactate Dehydrogenase (LDH) experiment, you will need 50ml of buffer A150. Buffer A150 is 30mM
torisob [31]

Answer:

The answer is "20 \ mL"

Explanation:

Given:

Molarity= number of moles

because it is 1 Liter

\to \frac{0.03\ moles}{1.5 moles}=0.02\ L= 20 \ mL \ of\  Tris\\\\

therefore,

it takes 20 mL of Tris.

\to \frac{0.150 \ moles}{5\ moles} =0.03\ L\\\\

                     = 30 \ mL \ of\ Nacl

So, take 20 \ mL\ of\ NaCl.

How do test with crash dummies, seat belts, and air bags illustrate newton's first law of motion??
Liono4ka [1.6K]

Answer:

Newton’s law of inertia is illustrated in tests with crash dummies, seat belts, and airbags, wherein the object stays in motion unless there is an unbalanced force applied to it.

Inertia is the main reason why there are seatbelts and airbags in the car. In this case, when the seatbelt is trapped to the passenger, the passenger experiences the same state of motion as the car. If the car accelerates/decelerates, the passenger experiences it too. When the car experiences collision, an unbalance force is acted upon it. This causes the car to stop abruptly, and the passenger shares the same state of motion because of the seatbelt and the airbags that apply the unbalanced force to stop the passenger to go forward.
