Which is the MOST accurate description of diffusion of materials through the cell membrane in order to maintain homeostasis?

Chemistry

Lelechka [254]3 years ago

Answer:

The correct answer will be option-D

Explanation:

Diffusion is the process of the movement of solute particles on the basis of the concentration gradient.

During homeostasis or the process of maintaining the internal environment of the body, the nutrients which could be the molecules or ions move from the region of high concentration or amount to a region of their low concentration through the cell membrane.

The concentration of calcium inside the cells during homeostasis is maintained by the diffusion of the calcium ions. Thus, option-D is the correct answer.

How long does it take the sun to melt a block of ice at 0∘c with a flat horizontal area 1.0 m2 and thickness 1.8 cm ? assume tha
VLD [36.1K]
This is a problem involving heat transfer through radiation. The solution to this problem would be to use the formula for heat flux.

ΔQ/Δt = (1000 W/m²)∈Acosθ

A is the total surface area:
A = (1 m²) + 4(1.8 cm)(1m/100 cm)(√(1 m²))
A = 1.072 m²

ΔQ is the heat of melting ice.
ΔQ = mΔHfus
Let's find its mass knowing that the density of ice is 916.7 kg/m³.
ΔQ = (916.7 kg/m³)(1 m²)(1.8 cm)(1m/100 cm)(<span>333,550 J/kg)
</span>ΔQ = 5,503,780 J

5,503,780 J/Δt = (1000 W/m²)(0.05)(1.072 m²)(cos 33°)
<em>Δt = 122,434.691 s or 34 hours</em>
