Which best describes the permeability of a membrane?
O A. The total thickness of the membrane
B. The flexibility of the membrane
C. The number of molecules in the membrane
D. The ability to allow materials to cross a membrane

Answers

Answer:

D

Explanation:

D. is correct because the membrane works like a security guard and only allows certain materails to cross the membrane. The definition of permeability is the state or quality that allows something to pass through.

Permeability is a standard of easy motion of liquid and gases through a membrane or material. They allow the transportation and exchange of gases in a cell.

The statement that best describes the permeability of a membrane is:

Option D. The ability to allow materials to cross a membrane.

This can be explained as:

Permeability is a physical property of membranes and substances that allows the other molecules to move through them.

It acts as a barrier from substances entering and exiting the cell or membrane and maintains the balance in a system.

Therefore, permeability is the allowance of materials across the membrane.

Buffers are substances that help resist shifts in pH by (From the close reading exercises)

A. releasing H+ to a solution when acids are added.

B. donating H+ to a solution when bases are added.

C. accepting H+ from a solution when acids are added.

D. both donating H+ and accepting H+.​

Answers

Answer:

Buffers are substances that help resist shifts in pH by both donating H⁺ and accepting H⁺ (option D).

Explanation:

A buffer is a chemical substance capable of balancing the pH of a solution, when the balance is altered by the addition of an acid or a base. They are also called cushioning solution, and can be formed by an acid and its base conjugated, with a specific range of action.

The presence of a buffer in a solution has the ability to release hydrogen ions (H⁺) or accept them, helping to balance the pH, in the presence of a base or an acid, respectively. That is, a buffer can yield H⁺ to a solution when there are few or accept H⁺ when its content is high.

The other options are not correct because:

    A. Buffers do not release H+ into a solution when acids are added, but accept them.

     B and C.  Giving up H+ to a solution when bases are added or accepting H+ from a solution when acids are added are effects that buffers can potentially do, which is described in the text above.

Compared to the Sun, the star Betelgeuse is
A. Less luminous and warmer
B. Less luminous and cooler
C. More luminous and warmer
D. More luminous and cooler

Answers

The answer to that is A

Red supergiant star Betelgeuse is around 764 times as massive as the Sun. To put that into perspective, the diameter of Mars' orbit around the Sun is 328 times that of the Sun. Thus, option A is correct.

What is the comparison of Sun and star Betelgeuse?

Betelgeuse is 640 light years away from the sun. Given that the star is only 10 million years old, it will die young like earlier supergiants.

The sun, in contrast, is only approximately halfway through its life and is nearly 4.6 billion years old.

Betelgeuse is one of the gleaming stars in the night sky and can be seen clearly on the right shoulder of the constellation Orion.

Betelgeuse is a red supergiant that is 1,400 times bigger than our Sun and thousands of times brighter.

Therefore, Compared to the Sun, the star Betelgeuse is  Less luminous and warmer.

What do you mean by ecosystem?

An ecosystem consists of all the organisms and the physical environment with which they interact. These biotic and abiotic components are interconnected through nutrient cycles and energy flows. Energy enters the system through photosynthesis and is incorporated into the plant tissue.

The term "ecosystem" was first used in 1935 in a publication by British environmentalist Arthur Tansley. The term was coined by Arthur Roy Clapham, who coined the word at Tansley's request.

The main ecosystem types  are forest, desert, rainforest, grassland, tundra, savanna, and mountain ecosystems.

Animals and plants that are unable to adapt to their environment will become

Answers

Explanation:

It really depends on how the question is phrased. Animals and plants that are unable to adapt to their enviroment will become- Hold it right there. How long will they be unadaptable? Is this forever? If so then yes, they will definately become extinct. If this is for a short amount of time then no, they will become prey, but there is also the fact that yes, they will become hungry. Because if they are not adapted then how are they gonna know the best sports for grub? Same thing for plants, if they can't adapt to the climate, they cannot produce food for themselves. Basically, if its a simple question then forget about everything else. It's Prey, because animals that can't adapt to their enviroment are immedietly in danger. Now if this question has more to it then I would go for C. But overall Just go with prey for now.

You never have to worry about wastewater becoming contaminated because it can run through local treatment plants, true or false?

Answers

A person still have to be worried about wastewater becoming contaminated even though it passes through local treatment plants.

Wastewater refers to the water they has been used. It consists of the substances like human waste, oils, chemicals , food scraps etc.  

Even though used water runs through local treatment plants, it should be noted that not all the solid waste are removed as some of the waste will still end up getting into nearby rivers or streams and this can result in contamination when one eventually uses such water.

In conclusion, one still has to be worried even though the wastewater runs through local treatment plants. Therefore, the correct option is False.

Explanation:

This actually happened to me! Since you don't fully kill off all the bacteria, they will mutate and become resistant to the medication.

A particle of rain water has just reached the ocean. In what order will the particle now complete the following steps of the water cycle?

Answers

Evaporation will probably be the next step. The water cycle consists of a few steps. Most of which you should know. But yeah evaporation would most likely be next.

Answer:

evaporation - condensation - precipitation - surface runoff

Explanation:

For a water particle that has just reached the ocean, the correct order of the water cycle is as follows: evaporation (liquid water changes to water vapor) → condensation (water vapor changes to liquid water) → precipitation (water falls to the Earth's surface) → surface runoff (water travels along the surface of the Earth into a reservoir, such as an ocean). The water cycle is a continuous cycle with no strict beginning or end.
