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

Blood is considered a colloid because it contains ____________ in the plasma. Most of these are produced by the ____________ . C
tekilochka [14]

Answer:

Proteins, Liver, Osmotic, Fluid, Into The Blood, Decrease.

Explanation:

Blood is considered a colloid because it contains proteins in the plasma.

Most of these are produced by the liver.

Collectively, these substances exert osmotic pressure and prevent the loss of fluid from the blood as it moves through the capillaries.

The pressure exerted by the plasma proteins is called colloid osmotic pressure.

This force is responsible for moving fluids into the blood and preventing excess fluid loss between blood capillaries and the interstitial fluid.

If plasma protein levels decrease, colloid osmotic pressure will decrease.

I hope this answer helps.

Which of the following statements about wings is true?
svp [43]

Answer:

Option (A), (B), (D) and (E).

Explanation:

Wings are present in class Aves that helps the birds to fly. Wings provides the means of locomotion and also allow the sexual selection in case of birds. The wings are the modified forelimb of birds.

The bats wings are ancestral whereas birds have derived wings. Birds and reptiles (turtle) mostly have ancestor with wings. On the basis of wings we cannot construct a phylogeny tree. Hence, wings are not the ideal characteristics for the construction of a phylogenetic tree.

Thus, the correct answer is option (A), (B), (D) and (E).
