You are enjoying your vacation on the coast and decided to go snorkeling. Your tidal volume is 460 mL and breathing rate is 14 b
m_a_m_a [10]

Answer:

Option C

Explanation:

Option

A. 6440 mL/min

B. 4340 mL

C. 3500 mL/min

D. 2940 mL/min

Solution

It is required to find the minute ventilation which is equal to the product of rate of breathing and the total amount of gas being inhaled or exhaled per breathe.  Let this minute ventilation be denoted by "V_f"

Thus,

V_f = TD * B_r

where TD is the tidal volume and Br is the rate of breathing

Substituting the given values we get

V_f = 460 *14 \\V_f = 6440

We will now reduce the air held in the conducting zone of respiratory system

Air held per breathe = 210

Total Air held

= 210 * 14 \\= 2940

Amount of fresh air one can breathe in and out every minute

= 6440 - 2940 \\= 3500

Hence, Option C is correct

This family of ATPases is structurally related to the pumps that acidify lysosomes and vesicles; however, they usually function
Vsevolod [243]

This family of ATPases is structurally related to the pumps that acidify lysosomes and vesicles; however, they usually function in reverse, generating ATP from ADP and Pi using proton gradients across membranes is called F-type pumps.

  • The inner membrane of mitochondria and bacterial plasma membranes both contain F type pumps, which are necessary for the generation of ATP.
  • It is also known as the ATP synthase complex or Complex V. By letting these protons passively return to the matrix, they use the proton gradient created by the flow of electrons to produce ATP.
  • The F1 motor is the ATP turnover motor and,
  • In mammals, the F0 motor, which is in charge of ion translocation, has nine subunits, nine of which are likely centered on the membrane's A, B, and C subunits, along with D, E, F2, F6, G2, and 8 subunits.

Calculate the mass of the book on the moon.<br> On moon surface gravity (g) is 1.6 N/kg
mafiozo [28]

Answer:

The Moon has a smaller mass than the Earth and so the pull of gravity by the moon on an object is smaller than on the earth. The moon has a smaller gravitational field strength. On the Moon, g = 1.6 N/kg.
