Answer:

the Frequency remains constant

sleet_krkn [62]3 years ago
3 0

Answer: So if a wave slows down, its wavelength will decrease. ... Although the wave slows down, its frequency remains the same, due to the fact that its wavelength is shorter. When waves travel from one medium to another the frequency never changes. As waves travel into the denser medium, they slow down and wavelength decreases.

Higher viscosity of blood will increase the amount of stress placed on the heart while it is pumping. Viscosity of blood is high
Paul [167]

Answer:

C) hematocrit is highest

Explanation:

The viscosity is the property of the fluid substance related to the flow of the resistance. The flow of the resistance increases when the amount of content in the fluid increases.

The flowing blood contains the water and the other components like the cells and proteins therefore it also exhibit the viscosity. The viscosity in blood happens when the cells and molecules interact with each other therefore measure of these components indicated about the viscosity of the blood.

The hematocrit is the ratio of the proportion of the red blood cells present in the blood to the total volume of the blood. The viscosity of blood, therefore, increases when the hematocrit is high and decrease when the hematocrit component is low.

Thus, Option-C is the correct answer.

Surfactant:
BARSIC [14]

Answer:

The correct answer will be option-D

Explanation:

Pulmonary Surfactant is a complex substance produced by the pneumocytes epithelial II cells in the alveolar sac.

The surfactant is composed of the proteins and lipids which plays a role in keeping alveoli open by reducing the surface tension formed between the air and liquid.

The surfactant act by forming a monolayer surface film which helps reduce the surface tension.

Thus, option-D is the correct answer.
