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.

D. protected, but not unqualified.

Abortion is the removal of the foetus in the womb of a woman before it becomes fully developed into an infant.

However, it does not approve of the act in all states because it is not yet established that abortion is legal in many states.

This leads to a difference in opinion because the right to privacy is protected, but the practise of abortion is denied.

Therefore, the correct answer is option D

Triangle K M L is shown. Line L K extends through point J to form exterior angle J K M. Which statement regarding the diagram is true? m∠MKL m∠MLK = m∠JKM m∠KML m∠MLK = m∠JKM m∠MKL m∠MLK = 180° m∠JKM m∠MLK = 180°

Answers

The exterior angle of a triangle is the sum of the opposite interior angles.

The true statement is: [tex]\mathbf{(b)\ \angle JKM = \angle KML + \angle MLK}[/tex]

From the figure (see attachment), we have:

∠JKM as an exterior angle to ∠KML and ∠MLK

In a triangle,

The exterior angle equals the sum of the opposite interior angles.

This means that:

[tex]\mathbf{\angle JKM = \angle KML + \angle MLK}[/tex]

Hence, the true statement is: [tex]\mathbf{(b)\ \angle JKM = \angle KML + \angle MLK}[/tex]

Why do lunar and solar eclipses not happen every month? Eclipses only occur during full and new moons. Earth rotates around its axis faster than the moon. The moon and Earth only travel through the penumbras. The tilt of the moon’s axis does not allow for monthly alignment.

Answers

The lunar and solar eclipses do not happen every month because the tilt of the moon’s axis does not allow for monthly alignment. It is for that reason we cannot observe a lunar/solar eclipse every month.

A solar eclipse occurs when the Moon moves between Earth and the Sun.

Moreover, a lunar eclipse happens when Earth moves between the Sun and the Moon, thereby partially or totally shadowing the Moon.

The Moon's orbit the Earth lies in a plane tilted by 5.15° with regard to the plane that Earth's orbit about the Sun.

If the Earth and Moon orbit on exactly the same plane around the Sun, then we could observe both a lunar eclipse and solar eclipse every month.

when attempting to control someone or something, do people compromise their own freedom in the process?

Answers

Perception differs for a lot of people. I believe that attempting to control someone or something, will not make one compromise their own freedom in the process.

Why attempt to control someone if you are going to loose your right to do whatever you want or be free. One's aim to control is to be able to do what you want.

Freedom is the right of an individual to be free and even though it can be compromised by the evil intensions of other people, it is not right to so it to yourself.

Lossing your freedom over something is not worth it. Though some people do compromise their freedom for anything but not in all situations.

So therefore, I believe that people do not compromise their freedom at all and Lost of freedom is not what a person desires.

the concentration of h+ ions inside the mitochondrial matrix is lower than it is in the cytosol or the mitochondrial intermembrane space. what would be the immediate effect of a membrane-permeable compound that carries and releases protons into the mitochondrial matrix?

Answers

The immediate effect of a membrane-permeable compound that carries and releases H+ into the mitochondrial matrix would be the inhibition of ATP synthesis. This process (ATP synthesis) requires an H+ gradient.

Mitochondria are the energy center of the eukaryotic cells, which generate energy in the form of ATP by a process called cellular respiration.

Cellular respiration has three main phases: glycolysis, the Krebs cycle and oxidative phosphorylation

During oxidative phosphorylation, a chain of transport of electrons across the inner mitochondrial membrane is coupled to the generation of an electrochemical proton (H+) gradient, which is used to synthesize ATP.

This electrochemical gradient is created by pumping H+ from the matrix to the inner membrane space of the mitochondria.
