Both things are bad to your health but vaping has a minor impact in your health than cigarettes.
Explanation:
Even though vaping has a lot of chemicals that not just include nicotine but other substances that are toxic and that stay in your lungs for a long time giving it time to damage your lungs from the inside,
Cigarettes have over 7,000 toxic chemicals that can cause cancer and / or other illness in your body. This cancer can be caused inside your lungs but it can also give you cancer in other certain parts of your body.

Why are spines considered a physical characteristic adaptation in cactus?
a cactus with sharp spines
The spines make the cactus look taller.
The spines protect the cactus from animals.
The spines allow for easier photosynthesis.
The spines are the seeds of the cactus.
Answers
Answer:
Explanation:
Spines are considered a physical characteristic adaptation in cacti because they help the plant to survive in its dry and hot environment.
The spines serve to protect the cactus from herbivores and other animals that might eat or damage it. They also help to regulate the temperature of the cactus by reducing the amount of sunlight that hits its epidermis. Additionally, the spines help to reduce water loss by minimizing the amount of surface area over which water can be lost through transpiration. Thus, spines are an important adaptation that enables cactus plants to survive and thrive in their harsh and arid environments.

What element does this model represent?
Answers
Answer:
[tex]$\tex$ Option 2: Aluminum (Al)[/tex]
Explanation:
When we are given Bohr models, we will be given a circle with rings surrounding it. The circle in the center of the model represents the nucleus, which contains the neutrons and the protons. The rings will have spherical structures that are attached to them in an orderly fashion - these model the electrons of an atom.
Protons are positively-charged subatomic particles that also identify the atom's chemical identity and atomic number. Using the number of protons, we are able to identify the element. The neutrons are the neutrally-charged subatomic particles that give an atom its weight. When you look at a traditional periodic table, you'll see that the square that houses an element has its symbol, atomic number, and atomic mass. The atomic mass is equivalent to the sum of the protons and neutrons.Electrons are negatively-charged subatomic particles that give an atom its overall charge. In order for an atom to be stable and neutral, the electrons must equal the protons. Otherwise, we have an unstable atom called an ion with either a positive or a negative charge. This is dependent on whether an atom has gained or lost electrons.When we reference the model, we will see that there are 13 "p" and 14 "n" within the green circle. The "n" refers to neutrons and the "p" refers to protons. We can also count the red spheres and make quick observations about these: there are 2 red spheres on the innermost ring - for simplicity reasons, we will title this ring as r = 1. There are 8 red spheres on the middle ring - this ring will be titled r = 2. Finally, we can see that there are 2 more electrons in the outermost ring - this ring will be titled r = 3.
Now, because we have 13 protons, we know that the protons are equivalent to the atomic number.
If we check the periodic table, we will see that Silicon (Si) has an atomic number of 14. This doesn't match the number of protons, so we can rule out that a silicon atom is not the element shown.When we use the same process and check aluminum, we discover that Aluminum (Al) has an atomic number of 13. Since the number of protons and the atomic number are equal, we can conclude that this is the element.If we check Helium (He), we see that it has an atomic number of 2, so this is definitely not our element in question.Now that we have concluded that Aluminum is our element, we can check this to be sure. If we use the formula m = n + p (where m is the atomic mass, n is the neutrons, and p is the protons), we can check to be sure we have selected the right element.
The given mass of aluminum on the periodic table is 26.982 atomic mass units. We round to the nearest integer when it comes to this, so we round 26.982 up to 27 even.
Now that we have determined the atomic mass and we are given the number of both protons and neutrons, we can act as if we weren't given the amount of neutrons and only the mass and amount of protons. We can then use the equation to solve for the amount of neutrons and check that the selection we made is correct.
Steps
Substitute 27 for m and 13 for p.Subtract 13 from both sides to isolate the n and place the constants on the same side of the equation.Combine like terms by taking the appropriate operations (in this case, this is subtracting 13 from 27).Finally, because we are solving for n, you can reverse the equation (place the constant on the right and place the variable on the left; i.e., 72 = x → x = 72).[tex]27 = n + 13\\\\27 - 13 = n\\\\14 = n\\\\n = 14[/tex]
The work we just performed will allow us to confirm that because we solved for 14 neutrons, Aluminum (Al) is indeed the element represented by the model.
Hope this helps! :)

Answer/Explanation:
Is Fossil Fuel Overuse threatening your health? Pollution that not only can harm health but also foster climate changes. The Overuse of fossil fuel damages our health. For Instance, Burning fossil Fuel increates a carbon dioxide; to much CO_2 is harmful to our health. This Proves that Fossil fuel can harm our health. Burning fossil fuels could lead to developmental delays in children. This tells us it can be very harmful for children. To much Co_2 can cause children to have adhd. In the text it states children exposed to air pollution from fossil fuels have a significantly greater chance of developmental.Fossil fuels burning cause global warning that makes it difficult to grow crops. This reveals that Fossil fuels can be harmful for the environment. Burning fossil fuels can cause extreme weather and it can cause people to lose their homes and lives.

A) A
B) B
C) C
D) D
Answers
Answer:
C.
Explanation:
To make this easier, Mathematically, a function is a straight line (linear) that goes through the origin.
Graph B best supports the claim that the gravitational force between two point masses is a function of the distance between the masses. Therefore, option B is correct.
Which graph shows the given situation?The graph that best supports the claim that the gravitational force between two point masses is a function of the distance between the masses and is a hyperbolic curve with an inverse square relationship.
Therefore, the graph that shows the force of attraction between two point masses (y-axis) plotted against the distance between them (x-axis) in a hyperbolic curve with an inverse square relationship is the one that best supports the claim.
This graph should show a decrease in the force of attraction as the distance between the masses increases, and the curve should become steeper as the distance decreases. Hence, option B is correct.
