How does carbon move around on Earth?
Answers
Answer:
Carbon moves from plants and animals to soils. When plants and animals die, their bodies, wood and leaves decays bringing the carbon into the ground. Some is buried and will become fossil fuels in millions and millions of years. Carbon moves from living things to the atmosphere.

Explanation:
How does carbon move between the 4 spheres on earth?

How was Earth’s atmosphere changed during the Great Oxygenation Event?
Answers
Consequences of oxygenation. Eventually, oxygen started to accumulate in the atmosphere, with two major consequences. Oxygen likely oxidized atmospheric methane (a strong greenhouse gas) to carbon dioxide (a weaker one) and water.
Answer: .Early organisms created oxygen from other gases in the atmosphere
Explanation:
It is believed that the atmosphere emerged about 4,500 million years ago, by a process that can be explained in five stages.
In the first stage, the atmosphere was shaped by volcanic emanations, such as water vapor, carbon and sulfur dioxide, and nitrogen. At this point, oxygen was barely present.
In the second stage, as the Earth cooled, the water vapor condensed and formed the oceans. Carbon dioxide reacted with the rocks of the earth's crust to create carbonates - (CO32-); a portion of them, when dissolved in the seas, generated salt water.
In the third stage, approximately 3.500 million years ago, bacteria appear, capable of carrying out photosynthesis, that is, of producing oxygen. This facilitated the development of marine life.
Once the atmosphere obtained sufficient oxygen, the fourth stage appeared, the evolution of large organisms as animals capable of breathing air.
This is how the current atmosphere containing the gases created in each of the previous phases was reached. These are kept in motion by winds and rains, allowing humans, and other living organisms, to breathe. For this reason, without them there would be no life on the planet.

(c) H2 + CO2 ⇌ H2O + CO ΔH (41)
(d) MgO + CO2 ⇌ MgCO3 ΔH (−117)
(e) 2CO + O2 ⇌ 2CO2 ΔH (−566)
Answers
The equilibrium of the reaction (a), (d), and (e) will shift to the left side when the temperature is increased.
What is equilibrium law?Equilibrium law states that if the dynamic equilibrium gets disturbed by changing the conditions such as temperature, pressure, etc., then to reestablish equilibrium, the position of equilibrium will shift to counteract the change.
As we know that if the change of enthalpy (ΔH) is negative then the reaction is exothermic in nature and if the change in the enthalpy is positive the reaction is endothermic in nature.
Therefore, the reaction (a), (d), and (e) are exothermic reactions, and the reaction (b) and (c) are endothermic reactions.
On increasing the temperature, if the forward reaction is exothermic. Then the equilibrium will shift to the reactant side or left so that excess heat will be absorbed in the backward reaction.
Therefore, when the temperature is increased, the reaction (a), (d), and (e) will shift the equilibria to the left side.

how do i stop chewing my nails?
Answers
Answer:
keep your nails short
Explanation:
it will help you not to bite it
Answer:
1. Keep your nails trimmed short. Having less nail provides less to bite and is less tempting.
2. Apply bitter-tasting nail polish to your nails. Available over-the-counter, this safe, but awful-tasting formula discourages many people from biting their nails.
3. Get regular manicures. Spending money to keep your nails looking attractive may make you less likely to bite them. Alternatively, you can also cover your nails with tape or stickers or wear gloves to prevent biting.
4. Replace the nail-biting habit with a good habit. When you feel like biting your nails, try playing with a stress ball or silly putty instead. This will help keep your hands busy and away from your mouth.
5. Identify your triggers. These could be physical triggers, such as the presence of hangnails, or other triggers, such as boredom, stress, or anxiety. By figuring out what causes you to bite your nails, you can figure out how to avoid these situations and develop a plan to stop. Just knowing when you’re inclined to bite may help solve the problem.
6. Try to gradually stop biting your nails. Some doctors recommend taking a gradual approach to break the habit. Try to stop biting one set of nails, such as your thumb nails, first. When that’s successful, eliminate your pinky nails, pointer nails, or even an entire hand. The goal is to get to the point where you no longer bite any of your nails.
A student places six plants of equal sizes into six different, equal-sized pots containing the same amounts of potting soil and labels the pots U, V, W, X, Y, and Z. Using two pots in each of the three experiments, the student varies the amounts of sunlight, water, or air one plant receives but leaves the other pot unchanged. The tables show the factor varied in each pot and the observations made by the student after one week.
Which conclusion best explains the connection among all three experiments?
A. All plants grown in pots require the same amounts of the abiotic factors for their growth and survival.
B. All plants of the same size require the same amounts of the abiotic factors for their growth and survival.
C. The plants require a balance of all abiotic factors for their growth and survival.

Explain how the process of weathering changes rock to eventually, over a long time, to become soil.
Answers
Answer:
Rocks turn into the soil through the process of weathering. Weathering is when rocks are broken down into smaller pieces. Over time a large rock is broken into smaller and smaller pieces, eventually turning into soil. Chemical weathering occurs when water gets inside of a rock and reacts with some of the mineral components of the rock, chemically changing them and weakening the rock's structure. This causes the rock as a whole to break down, and over time chemical weathering can break a rock into small enough pieces to become soil. Once the rock is in very tiny pieces, it mixes together with organic and other inorganic elements to form the soil we are familiar with.

Recently, our team of geneticists has been studying how hamsters inherit fur length.
You are invited to join our team to assist in the process.
Let's take a look at our geneticist notebook to learn more about how traits are inherited.Let's take a closer look at cells. Inside of each cell is a nucleus. The nucleus is like the command center for the cell and houses all of the cell's genetic material, called chromosomes. Tightly wrapped in the chromosomes are individual proteins, called genes, on strands of DNA.raits are determined by the genes the hamsters inherit.
Each hamster can inherit the trait for long fur or the trait for short fur.Let's examine the hamsters that you will be investigating today.
