which of the following molecules can cross the lipid bilayer of a membrane directly, without a transport protein or other mechanism? select all that apply.

Answers

Answer 1

Answer:

Explanation:

Molecules can cross the lipid bilayer of a membrane directly, without a transport protein or other mechanism - water, oxygen, carbon dioxide, and lipids.

Osmosis is transport in which the movement of a solvent occurs through a semipermeable membrane from a less concentrated solution into a more concentrated one without any protein.

Diffusion is a process where the molecule moves from one part to another part through the membrane.

Diffusion and osmosis are types of passive transport that do not require energy

This kind of movement does not involve transport proteins or other complex mechanisms.

Large polar molecules like glucose, amino acids, ions move through a membrane with the help of proteins

small non-polar molecules such as oxygen, carbon dioxide by diffusion and small polar molecules like water

large non-polar molecules like lipids can cross the membrane without the help of proteins by osmosis.

Thus, Molecules can cross the lipid bilayer of a membrane directly, without a transport protein or other mechanism - water, oxygen, carbon dioxide, and lipids.

x = 150

Plug into any equation because both are equal anyway:

Which cell type is produced from meiosis? haploid diploid prokaryotic somatic

Answers

Meiosis produces cells that are 1N. Another word for this is haploid.

The cell type of the daughter cell in the meiosis is haploid. Hence, option A is correct.

What is meiosis?

Meiosis is given as the type of cell division that gives rise to the new daughter cell. It is the reduction division cycle that takes place in the cell, with the formation of four daughter cells.

The meiotic division forms the development of the daughter cells with the division of the chromosome sets. It is termed as reduction division as the number of chromosomes reduced to half in the daughter cells.

Thus, the cell type of the daughter cell in the meiosis is haploid. Hence, option A is correct.

One of the legs of a right triangle measures 2 cm and its hypotenuse measures 9 cm. Find the measure of the other leg. If necessary, round to the nearest tenth.

Answers

Answer:

The measure of the other leg = 8.8 cm

Explanation:

Given - One of the legs of a right triangle measures 2 cm and its hypotenuse measures 9 cm.

To find - Find the measure of the other leg.

Proof -

We know that,

For a right angle triangle,

Apply The Pythagoras Theorem , which states that

(Hypotenuse)² = (Base)² + (Perpendicular)²

Given that,

Hypotenuse =  9 cm

One leg = 2 cm

Let us assume that,

One leg is base and another leg is Perpendicular.

We also can suppose vice-verse, it does not affect the solution.

Now,

(Hypotenuse)² = (Base)² + (Perpendicular)²

⇒(9)² = (2)² + (Perpendicular)²

⇒81 = 4 + (Perpendicular)²

⇒81 - 4 = (Perpendicular)²

⇒77 = (Perpendicular)²

⇒√77 = Perpendicular

⇒Perpendicular = 8.775 ≈ 8.8

∴ we get

The measure of the other leg = 8.8 cm

The statement that represents the key difference between the Court’s view is the Court shifted from saying that segregation was legal to say that any laws made based on race would be subject to careful judicial scrutiny. The correct option is b.

What is a court?

Plessy v. Ferguson was a landmark 1896 Supreme Court decision that upheld the legality of racial segregation under the "separate but equal" principle. The case began in 1892, when African-American railroad traveler Homer Plessy refused to ride in a vehicle reserved for blacks.

The Supreme Court rejected Plessy's claim that his protected rights were violated, ruling that legislation that "implies only a juridical disparity" between whites and blacks was not unlawful. As a result, Jim Crow laws and segregated open lodging based on race became popular.

Therefore, the correct option is b.

• In two years, Billy will be: = x + 2

• Since in 2 years, he will be twice as old as he was 5 years ago, this will be:

x + 2 = 2(x - 5)

The equation to solve the question is:

x + 2 = 2(x - 5)

x + 2 = 2x- 10

Collect like terms

2x - x = 2 + 10

x = 12
