Explain how resting potential is maintained and how an action potential occurs.

Answers

Answer 1

Answer:

resting potential is maintained by ion leaks and ion pumps

action potential occurs by:

- depolarization

-repolarization

-hyperpolarization

Explanation:

Answer 2
Sodium-potassium pumps move two potassium ions inside the cell as three sodium ions are pumped out to maintain the negatively-charged membrane inside the cell; this helps maintain the resting potential.

A student has two solid blocks that have different masses. The student knows that each block is composed of a pure substance, but she wants to know if the blocks are composed of the same pure substance. Which of these would best show that the blocks are composed of different substances?

A.
Both blocks sink when placed in water.
B.
Both blocks can be scratched by a piece of glass.
C.
One block conducts electricity and the other does not.
D.
One block has a greater volume than the other block.

Answers

Answer: I think the answer would be (D) because mass and volume are kinda different and If one has a different volume then it would have a different mass right?

C is the correct answer.

Explanation:
A and b don’t show anything that is different between the rocks so they are both cancelled. With D, if a block has a greater volume that has nothing to do with the substances. This shows that C is the best answer because if one block conducts electricity, that means it is composed of something different (for example metal).

Explanation:

Mark as Brainliest Answer

Air travels through the following structures on its path to the alveoli (the site of gas exchange): nasal cavities (or oral cavity) > pharynx > trachea > primary bronchi (right & left) > secondary bronchi > tertiary bronchi > bronchioles.

What is breathing?

The trachea (windpipe), which is further separated into bronchial tubes, receives it from there. Bronchioles are another division of the bronchial tube, the little alveoli structure is where the bronchioles eventually come to a stop.

Through our noses, we breathe air into our bodies, after then, it moves via the larynx, pharynx, and nasal cavity before entering the windpipe, also known as the trachea.

Therefore, air enters both lungs through bronchi that branch off of the trachea.

What condition is required for piles of sediment to become a sedimentary rock?

1. Low force
2. High energy
3. High pressure
or 4. Low temperature

Answers

It is high pressure because sedimentary forms in layers of rocks are are very hardly compressed into a solid form.

Sedimentary rocks are created by the accumulation of already existing rocks or fragments of extinct organisms on the Earth's surface, hence option 3 is correct.  

What is a sedimentary rock?

Weathering causes rock fragments to become loose, which are subsequently moved to a basin or depression where sediment is trapped.

Sedimentary rock is created when sediment is firmly buried and gets compressed and cemented. Large boulders to tiny clay particles have been found in clastic sedimentary rocks.

The process of erosion involves moving weathering products from the weathering site, either as solid material or as dissolved components, to finally be deposited as sediment.

Therefore, sediment is any unconsolidated accumulation of solid, weathered material to become a sedimentary rock that requires High pressure, hence option 3 is correct.

can someone make a story about calcium? pls help me

Answers

Answer:

um a story about Calcium? sure... Pls mark me brainliest!

Explanation:

Calvin Calcium was strong. Calvin Calcium was sturdy. Calvin Calcium had very good teeth. He

was a happy little boy and drank all of his Phenyl-Free. But one day all that changed. Here’s what

happened…

“I’m not going to drink my ‘milk’ any more,” said Calvin one morning at breakfast.

“Oooh,” said his mother, “then you can get your calcium from green, leafy

vegetables.”

“No,” said Calvin, “I’m not going to eat green, leafy vegetables either.”

“Oooh,” said his mother, “what will happen to Calvin?”

It wasn’t too long before Calvin found out.

In May, it was time for Calvin to have his dental check-up.

“Oooh,” said the dentist, “you have four cavities, Calvin. Have you

been eating foods with lots of sugar? Have you been forgetting to brush your teeth?

Maybe you haven’t been eating enough foods that give you calcium.” The dentist

filled the four cavities, and Calvin’s teeth were fine again. Calvin didn’t mind—too

much.

But in July, Calvin and his friends, Fred and Linda, were

building a tree fort.

They were almost done when, whoops, Calvin lost his balance and

tumbled to the ground!

“My arm hurts!” wailed Calvin.

“Oooh,” said his mother, running from the kitchen, “we’d better go

to the doctor!”

Doctor Smith felt Calvin’s arm very carefully.

“Oooh,” said the doctor, “you have a broken arm, Calvin.”

He put Calvin’s arm in a cast, and Calvin couldn’t go out to play for a long

time. He missed splashing in Fred’s pool to get cooled off on hot days. He

missed Linda’s birthday party. They played lots of neat games and had his

favorite low protein foods. But most of all, he missed playing with his friends.

He could hear them playing ball and roller skating every day.

Calvin went back to the doctor because it was

taking so long for his arm to heal.

“Oooh,” said the doctor, “it looks as if you haven’t been

eating foods with lots of calcium to make your bones strong.”

The Calvin Calcium Story

One morning Calvin said to his mother, “I’d like some of my ‘milk’ for breakfast.”

So that morning Calvin drank his ‘milk’. It tasted very good.

At lunch, Calvin said, “I’d like some green, leafy vegetables, please.”

So that noon, Calvin had green, leafy vegetables. They tasted very good too.

At dinner, Calvin said, “I’d like some green, leafy vegetables AND some ‘milk’, please.”

So Calvin had collard greens and lots of his ‘milk’ for supper. How good they tasted!

Calvin’s arm was almost healed now. Soon he would be able to join his

friends at the pool, on skates, and in their ball games.

When Calvin went to the dentist that fall, he had only one cavity. Calvin said

he had been brushing his teeth after eating AND eating foods that give him

calcium, especially his ‘milk’.

Calvin was again a strong, sturdy, happy boy—with very good teeth and strong bones!

Calcium is nature's most renowned structural material. Indeed, calcium is a necessary component of all living things and is also abundant in many non-living things, particularly those that help support life, such as soil and water. Teeth, sea shells, bones and cave stalactites are all products of calcium.

Interestingly, calcium seems to come in fifth place wherever it goes: It is the fifth most abundant element by mass in the Earth's crust (after oxygen, silicon, aluminum and iron); the fifth most abundant dissolved ion in seawater (after sodium, chloride, magnesium and sulfate); and the fifth most abundant element in the human body (after oxygen, carbon, hydrogen and nitrogen). It is, however, the most abundant metallic element in the human body, 99 percent of which can be found in our bones and teeth (about 2 lbs. of it!), according to Chemicool.

In its pure elemental state, calcium is a soft, silvery-white alkaline earth metal. It is important to note, however, that calcium is never found in this isolated state in nature, but exists instead in compounds. Calcium compounds can be found in a variety of minerals, including limestone (calcium carbonate), gypsum (calcium sulfate) and fluorite (calcium fluoride), according to Chemicool. Calcium makes up about 4.2 percent of the Earth's crust by weight.

In order to isolate pure calcium, it must be extracted through electrolysis, a technique that uses a direct electrical current to separate elements from their naturally occurring sources. Once isolated, calcium is quite reactive and will form a grayish-white oxide and nitride coating when exposed to air.

RECOMMENDED VIDEOS FOR YOU...
Calcium (Ca) is No. 20 in the periodic table of the elements, appearing just below magnesium in the same column (Group IIA) as the other alkaline earth metals (a group of metals that are more chemically reactive than most metals). Calcium comes from the Latin word "calx," meaning lime. This is not a reference to the fruit, but rather calcium oxide (CaO), the useful building material derived from heated limestone.

Calcium is extremely important to the human body. Not only is it vital for bones and teeth, but it assists in muscle movement by carrying messages from the brain to all our body parts. Cells in all living things must communicate with, or "signal," one another. Calcium ions act as vital messengers between these cells and are necessary in all multicellular life forms. They also assist in the release of hormones and enzymes.

In food, calcium is found in mineral form. Foods high in calcium include dairy products — such as milk, cheese and yogurt — and some vegetables, such as kale, watercress, spinach and broccoli. In order for calcium to absorb properly, it should be taken with vitamin D. Magnesium is also necessary for proper assimilation and use of calcium in the body. In fact, if we take too much calcium and not enough magnesium, it can cause problems in the body.


Lime, or calcium oxide, produces a brilliant, intense light when exposed to an oxyhydrogen flame, according to Chemicool. In the 1800s, before electricity was invented, this substance was used to light up the theater so actors truly performed "in the limelight" — hence the saying.
When turtles (typically pet turtles) don't have enough calcium circulating through their blood, they may get an ailment called Metabolic Bone Disease, commonly known as Soft Shell Syndrome. For a turtle to be healthy, the calcium to phosphorous ratio should be 2:1. When their calcium levels are low, however, the mineral is leached from their bones in the body's attempt to balance things out. The result is soft bones, weakness and a soft, deformed shell, and it often results in death. The disease can be prevented with a proper diet and adequate sunlight (or other appropriate lighting for reptiles).
Stalactites and stalagmites, the icicle-shaped formations found in underground caverns, are formed slowly over time by the build-up of calcite residue. This occurs when water seeps through the cracks in the ceiling of a limestone cave, dissolving and carrying along traces of calcite, the building material of limestone. As the water drips from the ceiling, this calcite residue begins to build up at the site of the drip, eventually resulting in icicle-shaped stalactites hanging from the cave ceiling. This water dripping from the stalactites then forms stalagmites on the ground

Fossil are natural source of energy, it is made from decomposition of plants and animals. Fossil fuels are found in the earth's crust and it must contains carbon and hydrogen which could gives energy by the burning. Natural gas usually found in pockets above oil deposits. It is also found where natural oil is found.

Coal, oil including natural gas are the best examples of the fossil fuels.  Coal has been a material usually found in  the sedimentary rock deposits where rock and plants are buried from long time. Oil has been originally found as the solid material between layers of sedimentay rocks, like shale. This material has been heated and converted into a gasoline.

Read Article B.In the early days of arctic exploration, dogsled was often the only way to travel. The ice, snow, and extremely cold weather made using other animals, such as horses, impossible. Snowmobiles were not invented yet. Most explorers journeyed by ship until the ice made it impossible to continue. Then, they would switch to dogsled. The dogs, working together, were a well-oiled machine that could cover long distances in the cold.Sled dogs needed to have long, warm coats to survive the arctic temperatures. They had to be fast and able to run for long distances while pulling a heavy load. Most importantly, they had to work together as a team. This made northern dogs, such as Siberian huskies and Alaskan malamutes, the best choices for the sled teams. These dogs have long coats, with a double layer of fur to keep out the cold, and they have wide paws with webbed toes that act like snowshoes. They have been bred for more than 9,000 years to be working dogs in extreme winter weather. They are friendly, team-oriented, and purposeful dogs. In the days of the arctic explorers, the physical features and determined personalities of the sled dogs made long journeys in harsh conditions possible.To be in the best condition for pulling heavy loads, the dogs needed a diet that was high in fat. They ate whale and seal blubber and fatty meats during their long journeys, which kept them strong and gave them energy to keep going. The dogs' paws also needed special care to make sure that they did not become injured by sharp ice or extreme cold. Treating the paws with fat or wax helped the dogs to run safely and comfortably.Although the days of arctic explorers are long past, sled dogs continue to run through the snow and ice of the North. Dogsledding is now recognized as a sport, with many competitions taking place all over the world. One of the most well-known of these is the Iditarod, a race of almost 1,000 miles. It commemorates the Great Race of Mercy that took place in 1925 when dog sled teams were the only hope of a town that needed life-saving medicine. The race takes 811 days to complete and is run regardless of weather conditions. Teams of twelve or more dogs train with their handlers for years before competing. The race is long and one of the most challenging in the world. Dogs and their handlers must be in top physical condition to have any chance of winning.During the race, the dogs get multiple rest stops and are checked by veterinarians to make sure they avoid injuries. They eat high-fat, high-protein foods to give them the energy to continue, just like the dogs of the arctic explorers did. With the same determination that drove the dogs of the 1925 Great Race of Mercy, the dogs competing in the Iditarod run through even the worst blizzards and race to win.Which information would disprove the author's point that sled dogs need a long coat? Long coats keep the dog's abdomen and legs warm in extreme temperatures. Long coats get matted with ice and mud, making it difficult to keep clean. Long coats act as insulating blankets, making the dogs kennels a safe temperature. Long coats are easy to care for since the dogs shed their coats when it is warm. log13 X + log13 (12x-1)=1
