What is the difference between active transport and diffusion in terms of movement of particles?

[ad_1]

Answered by answersmine AT 22/10/2019 – 03:14 AM

Active transport is the movement of dissolved molecules into or out of a cell through the cell membrane, from a region of lower concentration to a region of higher concentration. The particles move against the concentration gradient, using energy released during respiration.

Hydrochloric acid is necessary in the stomach for the conversion of pepsinogen into its active protein-digesting form called __________.

[ad_1]

There are two systems in the human body that are responsible for the coordination between the functions of different systems to achieve the unity of the living organism’s body. These two systems are the nervous system and the endocrine system. The action of the nervous system is fast and takes a short time, while the action of the endocrine system is slow and takes a long time.

The functional unit of the nervous system is the nerve cell or the neuron. The neuron consists of a cell body and the axon. The cell body starts with the dendrites that receive the messages or the impulses from other neurons or from different sense organs or receptors. These impulses are then transmitted through the cell body. The cell body contains a nucleus and different organelles which help the nerve cell to perform its functions. The nerve impulse is then transmitted to the axon.

The axon is an extension from the cell body. There are some cells called Schwan cells that secrete a myelin sheath to insulate the axon from the surrounding medium. The insulated axons have more ability to conduct the impulses than non-insulated axons. The axon ends with the terminal arborizations. The terminal arborizations of a nerve cell connect to the dendrites of the next cell or to the afferent organ. The gaps between the dendrites and the terminal arborizations are called the synapses.

The nerve impulse is an electrochemical phenomenon i.e. an electrical phenomenon with a chemical nature. The membrane of the axon acts as a barrier between an outside positively charged medium and an inside negatively charged medium. This makes a potential difference of  -70mV. This state is called the resting potential. When the membrane is subjected to a stimulus, the positive charges enter to inside and the negative charges exit to the outside. The potential difference now becomes +40mV. This state is called the depolarization state. The point of stimulation acts as a new stimulus for the next point and so on. The membrane sooner gains its permeability again and the positive charges return to the outside and the negative charges to inside. This state is called repolarization.

The nerve impulse reaches the synapse. There are some neurotransmitters that are excited by the nerve impulse coming and carry the message across the membrane. Some receptors receive theses neurotransmitters on the dendrites of the next neuron. These receptors act as a stimulus for the new cell.

The correct answer of this question is : C i.e Gravitational < Weak nuclear force < Electromagnetic force < Strong nuclear force.

EXPLANATION:

There are four fundamental forces in nature which are known as gravitational force, weak nuclear force, electromagnetic force and strong nuclear force.

Out of these four fundamental forces, the gravitational force is the weakest forces in nature,but has infinite range.

Weak nuclear force is produced due to W/Z bosons. Hence, it is stronger than gravitational force but weaker as compared to electromagnetic and strong nuclear force. It is a short range force.

Electromagnetic force is the third one which is weaker as compared to strong nuclear force but has infinite range.

Strong nuclear force is a short range, spin dependent strong attractive force that arises between nucleons due to exchange of mesons.

Wear a hat, such as a baseball cap. Apply sunscreen only during the summer. Wear sunglasses that block at least 50 percent of the sun’s ultraviolet rays. Put on sunblock 30 minutes before going in the sun. 1 points Question 4 Which is the more questionable phrase when used in advertising? secret formula FDA-approved medically proven variation in efficacy 1 points Question 5 Which statement is true of cooling down after physical activity? A cool-down is a period of semistrenuous activity after physical activity. Cooling down increases blood flow to the muscles and decreases body temperature. Cooling down increases the lactic acid in your muscles, helping to protect them from injury. You should cool down for about 5 to 10 minutes after being physically active. 1 points Question 6 Which statement about dressing for physical activity is true? Clothes should be tight and lie flat against skin to prevent chafing. Rubberized or plastic clothing prevents you from sweating. In general, you should wear heavier weight clothing to keep muscles warm and flexible. You should wear a hat in cold weather and in sunny weather. 1 points Question 7 Which question is not relevant when evaluating advertisements? What is the product’s purpose? Who is the target audience? What is being advertised? How expensive is the product? 1 points Question 8 Which characteristics should you look for when choosing a shoe for physical activity? a sole that is exactly the same height at the heel and the toe a cushioned heel cup to protect the heel from impact a firm, molded inside to stabilize the foot a sole at least as wide as the upper part of the shoe 1 points Question 9 Which statement is true of electrolytes? The major electrolytes lost in sweat are hydrogen, potassium, and iron. Electrolytes help carry electrical impulses from one cell to another. Electrolyte replacement during physical activity is beneficial. Electrolyte concentrations decrease due to the loss of body water. 1 points Question 10 Which statement is true of warming up before physical activity? A warm-up is a period of semistrenuous activity that prepares the body for physical activity. A warm-up increases the amount of oxygen to your brain by raising your body temperature. You should warm up for about 15 to 20 minutes before being physically active. Stretching is important for flexibility and keeps your muscles from tightening up during physical activity.

You need to determine the number of ways in which 30 competitors from 50 can qualify. First, you have to realize that the order is irrelevant, that is: it is the same competitor_1, competitor _2, competitor _3 than competitor_3, competitor_2, competitor_1, or any combination of those three competitors.

So, the number of ways is which 30 competitors from 50 can qualify is given by the formula of combinations, which is:

C (m,n) = m! / (n! * (m -n)! )

=> C (50,30) = 50! / (30! (50 – 30)! ) = (50!) / [30! (50 – 30)!] = 50! / [30! 20!] =

Why salivary amylase is active in the mouth, but becomes inactive in the stomach?

[ad_1]

Answer:

The correct answer would be the first option.

Enzymes are bio-catalyst which increase the rate of biochemical reaction taking place in our body.

They reduce the activation energy of the reaction by forming the enzyme-substrate complex.

A specific substrate binds to the active site of a specific enzyme in order to form an enzyme-substrate complex.  

It is then converted into enzyme-product complex after which product is released and the enzyme is ready for another round of reaction.

Enzyme + Substrate → Enzyme-Substrate complex → Enzyme-Product complex → Enzyme + Product.

Which action is an aspect of both critical thinking and active listening? A.evaluating B.questioning C. mirroring D.paraphrasing

[ad_1]

Answer:

The correct answer would be A.

Explanation:

Both critical thinking and active listening requires you to evaluate what is happening, if you are actively listening to someone you want to evaluate what that person is saying so you know how much input you want to put into the conversation, and if you are thinking, you want to evaluate how logical is the answer and if it is true or not, how much evidence you have and how clear if your argument.

it is not B because if you are actively listening to someone who trusts you, you do not want to question what they are saying as they are confiding in you.

It is not C because you do not want to mirror what others are telling you, or what your conclusions are, it does not need to be a copy of what is happening, instead you want to be sure that your arguments are clear and true before repeating them.

It is not D because just like in C, you do not want to repeat or shorten what you are listening or whatever conclusion you are getting to need to be clear and logical instead of just paraphrasing anything.

Answer : The enthalpy change of the reaction is, -470.2 KJ/mole

Solution :

According to Hess’s law of constant heat summation, the heat absorbed or evolved in a given chemical equation is the same whether the process occurs in one step or several steps.

The balanced chemical reaction are,

(1) C_2H_2+H_2rightarrow C_2H_6 Delta H_1=-94.5KJ/mole

(2) H_2Orightarrow H_2+frac{1}{2}O_2    Delta H_2=71.2KJ/mole

(3) C_2H_6+frac{7}{2}O_2rightarrow 2CO_2+3H_2O    Delta H_3=-283KJ/mole

The balanced main chemical reaction will be,

4CO_2(g)+2H_2O(g)rightarrow 2C_2H_2(g)_5O_2(g) Delta H=?

First reverse the reaction 3 then adding the twice of reaction 3, twice of reaction 1 and then subtracting four times of reaction 2 from the addition of two reaction 3 and 1, we get the enthalpy change of the reaction.

The expression for enthalpy change of the reaction is,

Delta H_{formation}=[2times Delta H_3]+[2times Delta H_1]-[4times Delta H_2]

where,

n = number of moles

Delta H_{formation}=[2times (283)]+[2times (94.5)]-[4times (71.2)]=470.2KJ/mole

Therefore, the enthalpy change of the reaction is, -470.2 KJ/mole

Answer:

The length is 8 feet.

Step-by-step explanation:

we know that

the area of the rectangle is equal to

A=xy

where

x is the length side of rectangle

y is the width side of rectangle

In this problem we have

A=48 ft^{2}

so

48=xy —-> equation A

y=x-2 ——> equation B

substitute equation B in equation A

48=x(x-2)

x^{2}-2x-48=0

The formula to solve a quadratic equation of the form ax^{2} +bx+c=0 is equal to

x=frac{-b(+/-)sqrt{b^{2}-4ac}} {2a}

in this problem we have

x^{2}-2x-48=0

so

a=1\b=-2\c=-48

substitute in the formula

x=frac{-(-2)(+/-)sqrt{-2^{2}-4(1)(-48)}} {2(1)}

x=frac{2(+/-)sqrt{4+192}} {2}

x=frac{2(+/-)14} {2}

x=frac{2+14} {2}=8 ft  —–> the solution

x=frac{2-14} {2}=-6

The geographic feature that limited the expansion of West African civilization is the Sahara Desert. This element was difficult to reach and across, thus limited effectively trades and contacts between populations. Isolation is not a good characteristics if a civilation needs other resources to grow and cannot established trade routes.

Camels help increase trade across geographic barriers of northern Africa by carried heavier loads and traveled far without water. Camels are mammals that needs few water to be able to live. They have two big reserves where they carry all the water possible when it is possible to drink, and then they survived by adopting a series of bilogical behaviours that allows them to srvive even in the middle of the desert for days.

Sonni Ali was able to create such a wealthy kingdom by creating trade routes under Songhai’s control, allowing the kingdom to flourish. Sonni Ali realized that trade routes are essential to the prosperity of a civilation. Wealth initially derives from trade. He successfully managed to do that, trasforming the kingdom into a thriven, flourished entity.

Arab Muslims primarily interact with East African city-­states through trade. Arab Muslim were, and still are, great trades. They come from a tradition of trade, as even before they were united their way of living was primarly trade, so they made contact with a lot of culture, the east african city-states are one of those.

Trade affect the culture of East African city­states by attracted people from many regions to the city­states, bringing more cultural diffusion. One of the biggest effect of trade is not only the exchange of goods but also of people and culture. So, trade is beneficial because it helps a country or a place thrive by mizing culture, peeople and goods.

One of the effects of Mansa Musa’s pilgrimage to Mecca was that he forged new diplomatic and economic ties with other Muslim states. Again, trade is one of the biggest ties that countries could have together. In this case, the forge of new diplomatic and commercial ties helped Musa to achieve a thrive never experienced before.

If all the genes of E. coli were active at once, what would result? 1. Conversation of energy and resources 2. Underproduction of enzymes 3. Cellular dysfunction 4. Increased rate of cell reproduction

[ad_1]

Answer: The correct answer is –

D) giraffes having increasingly longer necks over time.

Natural selection is an evolutionary mechanism that was proposed by Darwin.

According to this mechanism, organisms that are better capable of adapting to their changing environmental conditions, survive and increase their number through reproduction whereas other are eliminated from the population.

Example – Long neck of Giraffe, which is much elongated, lofty stature, that was beautifully adapted for browsing on the higher tree branches. This was an adaptation with slow and gradual change in the gene frequency as the lower vegetation was eaten by other animals. Due to this, giraffes had to search for other source (that was higher tree branches).

This is considered as a peculiar example of natural selection.

Answer Copper atoms have loosely held electrons; this means they can freely move in and out of the nucleus of the atom. Copper atoms have a loosely held free electron in their outer shell that is able to move freely to other atoms. Copper and some other metals have highly active inner shells. This means that electrons can be freely exchanged between shells. Copper has a small number of electrons; this means it can easily shed these electrons and take electrons from other atoms. …?

The easiest way to solve this is to think about the number of times the digit 1 appears in each decimal place (ie, ones, tens, etc). 

Assuming the pages are numbered 1-500, then the digit 1 will appear in the ones place on page 1, 11, 21, … and so on, up to 491. So, every 10 consecutive integers, the digit 1 is in the ones place exactly once. To be more precise, it appears in 50 ones places. 

The digit 1 will appear in the tens place on pages 10,11, …, 19, 110, 111, …, 119, and so on. So in every 100 consecutive integers, the digit 1 is in the tens place exactly 10 times. If you count, it appears 50 times. 

Finally, the digit will appear in the hundreds place from pages 100-199, which is 100 pages. 

So the digit 1 appears 200 times.
