Why would teens choose to vape, when we have the last 30 years of evidence proving the
consequences of smoking tobacco products ?
Answers
Answer:
look down below
Explanation:
Many teens consider the brand to be an entirely different device from an e-cigarette or just smoking in general. Teens also think that vaping is safer than smoking, which it really isnt if they havent already used tobaccco products. Another point is peer pressure. Most teens succumb to it.

Explanation:
The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.

What type of carbon cycling occurs when stored carbon in organisms is released when they die, and when carbon from dead organisms can be released underground in the form of coal, oil, or natural gas?
long-term carbon cycling
carbon storage cycling
carbon release cycling
short-term carbon cycling
Answers
Answer:
The type of carbon cycling that occurs when stored carbon in organisms is released when they die, and when carbon from dead organisms can be released underground in the form of coal, oil, or natural gas is called the geological carbon cycle. This cycle involves the long-term storage of carbon in rocks and fossil fuels like oil, coal, and natural gas. Carbon is also released back into the atmosphere through various mechanisms such as volcanic eruptions, fires, and burning of fossil fuels.
Explanation:
The carbon cycle can be divided into two main categories: the short-term carbon cycle and the long-term carbon cycle. The short-term carbon cycle involves processes that cycle carbon through the Earth system on roughly annual/decadal timescales. This includes photosynthesis, respiration, and decomposition of organic matter. The long-term carbon cycle takes millions of years to come full circle and involves the movement of carbon between rocks, soil, ocean, and atmosphere through a series of chemical reactions and tectonic activity. Carbon is stored in rocks and fossil fuels like coal, oil, and natural gas for a long time in the geological carbon cycle. Carbon is also released back into the atmosphere through various mechanisms such as volcanic eruptions, fires, and burning of fossil fuels in both short-term and long-term cycles

( 1 Point ) At certain times of the year, five planets can be seen from earth, including mars and
A. Juno
B. Neptune
C. Saturn
D. Uranus
( please don’t be inappropriate with option D )
Answers
At certain times of the year, five planets can be seen from the Earth in alignment. These are Mercury, Venus, Jupiter, Mars, and Uranus. So the correct option is option D.
When does the alignment of five planets occur and be seen in the sky?
Such a planetary alignment takes place when the planets come together on one side of the sun at the same time. This alignment occurs as a result of five planets coming in one line in the sky. These planets can be seen with the unaided eye and do not require a telescope to be seen from the Earth. This is because these planets are the brightest planets.
These planets change positions and go through certain phases where they can be sighted from the Earth except for Uranus which can be seen using a telescope in the evening sky. Uranus is the seventh planet in the solar system.

What would happen to your body if your sodium level is too high? too low?

Will mark brainliest but you have to answer EVERY SINGLE THING CORRECTLY
Answers
Answer:
Too much sodium in the diet can lead to high blood pressure, heart disease, and stroke. It can also cause calcium losses, some of which may be pulled from bone. Hyponatremia is a condition characterized by low levels of sodium in the blood. Its symptoms are similar to those caused by dehydration. In severe cases, the brain may swell, which can lead to headaches, seizures, coma, and even death.

There is more than one way to produce the amino acids that build a protein. What does this mean?
Answers
The statement that there is more than one way to produce the amino acids that build a protein means that there are multiple ways that the body can obtain the necessary amino acids from the nutrients.
What is protein?There are two main ways that the body can obtain these amino acids: through dietary intake and through the breakdown of existing proteins in the body. The human body cannot produce all the amino acids it needs on its own, so it must obtain the remaining amino acids through the diet. These are known as essential amino acids, and they include histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.
Hence, there is more than one way to produce the amino acids that build a protein, meaning that there are multiple ways that the body can obtain the necessary amino acids from the nutrients.

C.

Answers
it’s melting
From the diagram of the rock cycle the missing part is ( B ) ; Melting
Magma is a hot liquid/semi-liquid rock that is usually formed under the earth due to high pressure and temperature present in the inner core of the earth. magma is obtained by the melting down of existing rocks ( Igneous, sedimentary and metamorphic rocks ) under high pressure and temperature in the earths core.
Magma is released to the earth surfaces during volcanoes therefore the missing term in the rock cycle is melting
Hence we can conclude that from the diagram of the rock cycle the missing part is Melting.

Hypothesis: If fizzing tablets are placed in cold water, then they will dissolve faster. An experiment is designed to test the hypothesis. Two glasses of water are filled with water. One glass
is filled with 200 mL and heated to 50 degrees Celcius, and the other is filled with 150 mL of water and cooled to 4 degrees Celcius. One fizzing tablet is put in the heated cup, and two
fizzing tablets are put in the cooled cup. A stopwatch is used to record how long it takes the tablets in each cup to stop fizzing. The glass with heated water stops fizzing in 45 seconds,
and the glass with cooled water stops fizzing in 5 minutes. What errors were made? Select all that apply
