The Gulf Stream passes from the Gulf of Mexico, northward along the coast of eastern North America, and eastward toward Ireland,

the United Kingdom, and Scandinavia. Without the Gulf Stream, these regions would be colder than they are. How does the Gulf Stream keep these regions warm?

Answer: It brings warm water, which heats the overlying air

Explanation:

Ocean currents affect the overlying air. Warm currents warm the air, while cold currents cool the air. When currents are close to the shore, the warm or cool air influences the temperature of the shore region.

The Gulf Stream is a warm current, so it makes those regions warmer than they might otherwise be.

I believe it is keeping these regions warm because the water is flowing from the SOUTHERN part of these regions, like, how it starts from the bottom of the US, (aka Louisiana, Mississippi), and it gradually flows upward, but hot always overrules cold, so the cold water that it is flowing into is becoming warmer as it passes into the warm water from the gulf of Mexico.
Hope that this helps :)

Marcus discovered that sodium (Na) is found in Group 1, Period 3 on the periodic table. Where should Marcus look to find another
Leokris [45]

Answer:

1. A. Group 1

2. B. A chemical change occurred which is evidenced by the change in color of the solution.

3. D. Physical change because the chemical properties of the salt and water remained the same.

4. D. Sphere B will float because it is less dense than water.

5. C. Shredding them into smaller pieces.

6. A. Her model uses eleven white pom-poms.

   B. Her model uses twelve black pom-poms.

   E. Her model uses eleven yellow pom-poms.

7.  B. The liquids have different densities.

8.  D. Physical Properties: color, texture Chemical Properties: ability to rust

9.  A. Container A will have 1 liter of helium, and container B will have 1 liter of water.

Explanation:

1.

In the periodic table, <u>rows</u> represent the<em> period</em> that they are in, while columns represent the groups that elements are in. Elements in the same group (column) share similar properties. Since Sodium (Na) is found in group 1, elements that are similar in properties would be found in the same group.

2.  

A chemical change is marked with a change in color, production of gas, heat, and sometimes smell and light. A chemical change results in new products formed, in which the properties and identities of the reactants change as well because their atoms were rearranged. In this case, the <u>change in color </u>of solution shows that a chemical change had occurred.

3.

Earlier we said that chemical change results in new products, for physical change it does not. The substance will keep its identity. Like in the scenario, the salt and water did mix together, but when they were separated through evaporation, the salt <u>retained its identity</u> and so did the water. The substances involved merely changed phases. So this was a physical change.

4.

If the density of the object is more than the density of the liquid, the object will sink. On the other hand, if the density of the object is <u>less than the density of the liquid, it will float. </u>

If water has a density of 1g/cm³, the object that has the lesser density will float. First you solve for the densities of each object and it can be computed using the formula:

D = m/v

where D = density; m = mass; and v = volume

Sphere A:

d=\dfrac{m}{v} = \dfrac{24g}{19.4cm^3} = 1.23 g/cm^3

Sphere B:

d=\dfrac{m}{v} = \dfrac{13.6g}{17.0cm^3} = 0.8g/cm^3

So as you can see, only Sphere B has a density less or is less dense than water, so only Sphere B will float.  

5.

The groundskeeper shredding leaves is an application of physical change. As you can see, the identity of the leaves would be the same if you just shred them. Even if they change in shape and size, the leaves are still leaves, only smaller.

6.

A stable atom has the same number of electrons and protons. The number of protons is represented by the atomic number of an element.

Sodium has an atomic number of 11. This means that there are 11 protons (yellow pom poms) in a sodium atom. Since it is stable, you can also say that there are 11 electrons (White pom poms) as well.  

The number of neutrons can be determined by taking a look at the mass number of an atom. The mass number of sodium is 23. The mass number is the number of protons and neutrons combined.

23 = p + n

23 = 11 + n

23 - 11 = n

12 = n

The number of neutrons would be 12 (black pom poms).

7.

When two liquids do not mix, this means they are immiscible. The layers are formed because of the difference in density. Remember earlier about density and an object or substance's ability to float? Well it applies here too. The liquid on top is less dense than the one below it, so it floats up and the denser liquid sinks.

8.

Physical properties are things that you can observe using your senses. Chemical properties are properties that you can only observe when chemical structure is changed.

Seat cover has a <u>smooth texture. </u>  

Physical because it was determined by touch.

The front basket of the <u>bike is purple. </u>

Physical because it was determined by sight.

The <u>bike is rusted.</u>

Chemical because the metal changed its chemical structure as a result of a reaction.

9.

The sealed containers represent a closed system, or a vacuum where nothing goes in or out. In a closed system, just remember that matter is not created, nor destroyed. Simply put, this means that whatever it started with is what will it end up with.

In container A you have 1 L of helium gas, so since the container is sealed, none escaped. This means that you will end up with the same amount of helium gas as you did before. The same goes for the 1L of water in container B.

What are the functions and vessels of the heart, and what are some cardiac disorders that might be life-threatening to a person
zavuch27 [327]

Answer:

The cardiovascular, or circulatory, the system supplies the body with blood. It consists of the heart, arteries, veins, and capillaries. but the things that might be life-threatening to a person or animal are;

Explanation: angina is a type of chest pain that occurs due to decreased blood flow into the heart this can harm animals and people. there is also - - - arrhythmia,which is or an irregular heartbeat or heart rhythm,

- congenital heart disease, in which a problem with heart function or structure is present from birth.

-coronary artery disease, which affects the arteries that feed the heart muscle.

- Heart attack, or a sudden blockage to the heart’s blood flow and oxygen supply this can kill. heart failure, wherein the heart cannot contract or relax normally,

- dilated cardiomyopathy, a type of heart failure, in which the heart gets larger and cannot pump blood efficiently and the last one is  

- hypertrophic cardiomyopathy, in which the heart muscle walls thicken and problems with the relaxation of the muscle, blood flow, and electrical instability develop

these are only a few that can harm or even kill a living thing like and animal or person these things are really harmful.

I hope this helps you!!

Although antacids containing calcium carbonate can increase calcium intake, what effect would excessive consumption of the carbo
nata0808 [166]

Answer:

The blood pH will increase.

Explanation:

Antacids are the chemicals that works against the acids that produced in our stomach. Antacids are generally used to treat the excessive acidity of the stomach.

The intake of excessive carbonate base causes the release of gastric acid secretion in the stomach. Hence, the blood pH increases due to the presence of H + ions in the blood.

Thus, the blood pH will increase.

Use the scenario below to answer the following question
Nutka1998 [239]

Answer:

Nicko: So guys, i'm doing some crazy things with my test today, so the energy wasn't destroyed

Teacher: Why?

Friends: Yeah why loser

Nicko: Because we add a galon of gasoline to the vehicle and observe the vehicle as our friend drive it in a circle around us

Friends: Shut up lose-

Teacher: Guys shut up, Nicko.. can you explain more detail?

Nicko: After doing calculations we realize the vehicle did not travel nearly as far as our thought it would when it used the gallon of gasoline.

Teacher: What's your opinion about that Nicko?

Nicko: I claims that the energy could not have been destroyed, but cannot determine what happened to all of the energy.

Bob: It's my turn

Teacher: Nicko, you can go home now.

Nicko: Thank you teacher!

Teacher: *smile

Bob: Bye Nick!

Nicko: Bye Bob! Good Luck!

Bob: You too!

Unfortunately Nicko going to home with those all pain because of bully

Bully: Yo Nicko
