Which of the following best describes the relationship between the sun and Jupiter?

Softa [21]

Answer: B) Jupiter and the sun have a similar composition.

Explanation:The only significant difference between the sun and Jupiter is in the sizes i.e jupiter is smaller compared to the size of the sun.

However their similarities is in their composition i.e what they are made up (helium and hydrogen).

The core of Jupiter is made up of liquid metallic hydrogen and the sun's core or center is also made up 34% mass plasma of hydrogen.

So option B (Jupiter and the sun have a similar composition) best describes the relationship between Jupiter and the sun.

Describe how alveoli are adapted for gas exchange( 4 marks)

SashulF [63]

Answer:

they give the lungs a really big surface area. they have moist, thin walls (just one cell thick) they have a lot of tiny blood vessels called capillaries.

The walls of the alveoli are only one cell thick. This makes the exchange surface very thin - shortening the diffusion distance across which gases have to move. Each alveolus is surrounded by blood capillaries which ensure a good blood supply.Adaptations of the alveoli:

Thin walls - alveolar walls are one cell thick providing gases with a short diffusion distance. Moist walls - gases dissolve in the moisture helping them to pass across the gas exchange surface. Permeable walls - allow gases to pass through.

The concentration of cholesterol (C27H46O) in blood is approximately 5.0mM. How many grams of cholesterol are in 315mL of blood

ASHA 777 [7]

The weight of cholesterol is 0.6 g.

Here use the concept of molarity.

<h3>What is molarity?</h3>

The amount of a substance in a specific volume of solution is known as its molarity (M). The moles of a solute per liter of a solution is known as molarity.

Molarity = no. of moles/volume (in L)

<h3>Calculation:</h3>

Given,

Molarity, M = 5.0 mM = 5 × 10⁻³ M

Volume, V = 315 mL = 315 × 10⁻³ L

To calculate,

Weight of cholesterol =?

We know that,

Molecular mass of cholesterol, C₂₇H₄₆O = 386

No. of moles = weight/ molecular mass

The formula is modified as,

Molarity = weight of cholesterol/ (molecular mass) (Volume)

Put the values in the formula,

5 × 10⁻³ = weight of cholesterol/ (386) (315 × 10⁻³)

Weight of cholesterol = 5 × 10⁻³ (386) (315 × 10⁻³)

= 0.6 g

Hence, the weight of cholesterol is 0.6 g.
