Explain how the isotopes of an element differ. (1 point)
They each have a different number of electrons in their outermost energy level.
They each have a different number of protons in their nuclei.
They each have a different number of neutrons in their nuclei.
They each have a different charge.,

Answers

Answer 1
they will have a different number of neutrons in their nuclei
Answer 2
They each have a different number of neutrons in their nuclei.

Every atom consists of 3 basic particles, protons, neutrons, and electrons. The actual element is determined by the number of protons, and for a neutral atom, each proton has a corresponding electron. The neutrons which have no charge are in the nucleus and may have a different count for different isotopes of the same element. With that in mind, let's look at the options:

They each have a different number of electrons in their outermost energy level.
* This is constant for each element if the atom has a neutral charge. It can be changed electrically, but that doesn't affect what isotope it is, so this is a bad choice.

They each have a different number of protons in their nuclei.
* If the number or protons change, then you have a different element. So this is a bad choice.
They each have a different number of neutrons in their nuclei.
* This is the correct choice.

They each have a different charge.
* The electrical charge doesn't affect what the isotope is, so this is a bad choice.

Which of the following is the best definition of energy? (Points : 1)
the ability to generate electricity

the ability to generate heat

the ability to do work

the ability to produce fusion

Answers

Energy is best defined as "the ability to do work". This is the fundamental definition of energy which has been used by physicists for a very long time, and highlights the most important definitional property of energy - be it kinetic or potential - the capability to do work on objects by causing them to move.

The ability to do work

The most common definition of energy is the work that a certain force can do. Due to a variety of forces, energy has many different forms that can be grouped into two major categories: kinetic energy and potential energy.

A medical term that means puncture pleura to withdraw fluid is ____________.________________ ____________________

Answers

The answer is pleurocentesis.


The brainest answer would be appreciated. 

Final answer:

The medical term for puncturing the pleura to withdraw fluid is thoracentesis, a procedure performed to alleviate symptoms and analyze the cause of a pleural effusion.

Explanation:

The medical term that means puncture of the pleura to withdraw fluid is thoracentesis. This procedure is used when there is an accumulation of excess fluid in the pleural space, a condition known as a pleural effusion, which can interfere with normal breathing. Conducting a thoracentesis involves inserting a needle into the pleural space, often using ultrasound guidance, to remove fluid for both therapeutic relief and diagnostic analysis.

The pleural space normally contains a small amount of fluid which serves as lubrication, allowing the lungs to move smoothly against the thoracic wall during breathing. However, when this balance is disrupted by inflammation, infection, trauma, or other medical conditions, it can lead to pleurisy or other complications such as spontaneous pneumothorax (collapsed lung), which requires prompt medical attention.

Where in the body would you find low oxygen levels causing vasoconstriction and high levels causing vasodilation?
a. liver
b. lungs
c. kidney
d. heart?

Answers

The correct answer is the lungs. Usually, in the systemic organs such as the liver, kidneys, and the heart; hypoxia or low oxygen levels cause the blood vessels supplying them to vasodilate to increase flow of blood and prevent ischemia. Adequate oxygenation of systemic organs cause the blood supply to vasoconstrict to prevent pooling of oxygenated blood and shunt it to other organs that need the oxygen more.

However, in the lungs, the opposite is true because in the setting of hypoxia, the blood vessels of the lungs vasoconstrict as to shunt the blood to other parts of the lungs with adequate oxygenation for the blood to be adequately oxygenated. If there is adequate oxygen in the lungs, then blood vessels vasodilate to efficiently get the oxygen from the lungs. 
The answer for the question is the lungs.
Vasodilation means the smooth muscles in the blood vessel walls relax causing them to widen. The widening results in less vsacular resistance, thus the blood flow through the dilated vessel increases. Vasocontsriction on the other hand means the smooth muscles in the blood vessel walls contract causing them to narrow. The action results in blood flow through the vessels to be restricted.

Which cranial nerve is responsible for transmitting visual information?

Answers

the Optic nerve transmits visual info
Final answer:

The optic nerve is the cranial nerve responsible for transmitting visual information from the eye to the brain. It is one of the 12 cranial nerves in the human body which each have unique functions. Some cranial nerves transmit sensory information, others transmit motor information, and some a combination of both.

Explanation:

The cranial nerve responsible for transmitting visual information is the optic nerve. This nerve function includes transmitting visual signals from the eye over the axons of retinal ganglion cells, which form the optic nerve, to the brain. Specialized cells within this nerve carry various types of information such as form, movement, depth, brightness, color, and fine detail.

Humans have a total of 12 cranial nerves, each providing unique functions. For example, the olfactory nerve is responsible for transmitting information about smells from the nose to the brainstem, and the oculomotor nerve controls the opening and closing of the eyelid and some eye movements. However, when it comes to the transmission of visual information, the optic nerve is the primary player.

Generally, some cranial nerves transmit only sensory information, others mainly motor information, and some contain a mix of sensory and motor fibers, catering to the complex needs of our biological system.

Explain how ozone in the stratosphere is formed.

Answers

Stratospheric ozone is formed naturally by chemical reactions involving solar ultraviolet radiation (sunlight) and oxygen molecules, which make up 21% of the atmosphere. In the first step, solar ultraviolet radiation breaks apart one oxygen molecule (O2) to produce two oxygen atoms (2 O) (see Figure Q2-1).

Sunlight's UV rays (sunlight) and the oxygen molecules that make up 21% of the atmosphere interact chemically to create stratospheric ozone in a natural process.

What results in formation of stratosphere, earth atmosphere?

The very significant ozone layer is found in the stratosphere. The ozone layer aids in shielding us from the sun's ultraviolet (UV) rays.

In actuality, the ozone layer filters out the majority of the UV rays the sun emits at us. Without this layer of defense, there would be no such thing as life as we know it.

Oxides of nitrogen and volatile organic compounds, usually mentioned to as hydrocarbons, undergo chemical substance interactions that lead to ozone.

Both close to the earth and high in the atmosphere, this reaction is possible.

Therefore, The stratosphere contains the famed ozone layer.

The oceans absorb carbon through three processes that draw atmospheric carbon dioxide into the oceans: the physical carbon pump, the biological carbon pump and the carbonate pump. Molecules of CO2 enter the ocean by diffusing into the sea surface waters and dissolving as part of the physical carbon pump. All BUT ONE variable influences how much CO2 will diffuse in any given location. That is A) wind. B) salinity. C) water temperature. D) geographic location.

Answers

Answer:B

Explanation:

bbbbBBBBBBBBBBBBBBBBBBbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb

The variable that does NOT influence how much CO2 will diffuse in any given location is D) geographic location. The other three variables - wind, salinity, and water temperature - can all impact the amount of CO2 that diffuses into the sea surface waters.

For example, higher wind speeds can increase the rate of gas exchange between the atmosphere and ocean, leading to more CO2 entering the ocean. Salinity can affect the solubility of CO2 in water, and water temperature can impact the rate of biological activity that consumes or releases CO2.

The correct answer is geographic location, as this factor does not directly influence how much CO2 diffuses into the ocean. Wind, salinity, and water temperature can affect the solubility of CO2 in water and therefore impact the amount of CO2 that diffuses into the ocean in any given location.
