Can someone help me with the order of the carbon cycle ?

Answers

Answer:

First what is it? Carbon cycle is, nature's way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms.

1.Carbon moves from the atmosphere to plants. In the atmosphere, carbon is attached to oxygen in a gas called carbon dioxide (CO2). Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth.

2.Carbon moves from plants to animals. Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too.

3.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.

4.Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants need to get rid of carbon dioxide gas through a process called respiration.

5.Carbon moves from fossil fuels to the atmosphere when fuels are burned. When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas. Each year, five and a half billion tons of carbon is released by burning fossil fuels. Of this massive amount, 3.3 billion tons stays in the atmosphere. Most of the remainder becomes dissolved in seawater.

6.Carbon moves from the atmosphere to the oceans. The oceans, and other bodies of water, absorb some carbon from the atmosphere. The carbon is dissolved into the water.

What is Earth?

Earth, the third planet from the Sun, is the planet where all known life is found. Although the Solar System contains enormous amounts of water, only Earth is home to liquid surface water.

The ocean covers roughly 70.8% of Earth's surface, dwarfing the polar ice, lakes, and rivers. Earth's surface is made up of continents and islands for the remaining 29.2% of its total area.

Several slowly moving tectonic plates that make up the Earth's surface combine to create mountain ranges, volcanoes, and earthquakes. The magnetic field that forms the Earth's magnetosphere and diverts harmful solar winds is produced by the liquid outer core of the planet.

explain how mutation evolution might
occur in a population

Answers

Answer:

mutations create a new particular gene, a new allele. If that allele is passed down to the next offspring and the next, the mutation would be carried throughout the population. Some of the species in the population might not show any symptoms of a mutation or not feel the effects of it, but pass it down. If the mutation is neutral (causing no harm or no good), it may be passed down. If the mutation is beneficial to the species, and helps them survive, it may be passed down more. If the mutation is harmful, the mutation may eventually stop being passed down, and start to only appear if something happens genetically (mutation still may happen, but not because of passing down from parent to offspring).

Advanced Space Weather Activity
This lesson highlighted different types of space weather. If you were responsible for reporting space weather like Earth's weather is reported, how would you do it? What would you include?

Create any type of weather report to warn people about space weather activity. You can present it like a weather app, radio announcement, television news report, or newspaper weather section. You only need to pick one type of report to submit to your instructor.

They gave an example below however im confused if I should copy it and put my own words or if I should just make like a video or something!

One in every city. About 670,000,000,000 in total! It would tell people all around the world what the news up in space is ! For backup, I would also use a weather app but for space. People are on their phones everyday. Lets make it useful! The space weather app would tell people everyday what the weather is up in space, making them interested in space weather! For instance, Over at Mars, its currently 35° degrees! Many people are interested in space, let them know the weather of their favorite planets ! Make a channel on TV ! Hope this helps <3

Behavioural: aggression, agitation, difficulty with self care, irritability, meaningless repetition of own words, personality changes, restlessness, lack of restraint, or wandering and getting lost

Mood: anger, apathy, general discontent, loneliness, or mood swings

Psychological: depression, hallucination, or paranoia

Each is used to break down substances.
Each has a specific substrate.
Each has an optimal temperature and pH.
O
Each has an active site.

Answers

Answer:

Each is used to break down substances.

Explanation:

Enzymes merely speed up a chemical reaction, not necessarily break down substances.

Each enzyme is used to break down substances is not a characteristic of enzymes. The correct option is A.

Thus, enzymes aren't just utilized to degrade things. Enzymes perform additional crucial tasks in addition to being essential for the breakdown (catabolism) of substances. In living things, enzymes operate as biological catalysts to quicken chemical processes.

Enzymes achieve this by reducing the activation energy needed for a reaction to happen and thereby speeding up the reaction rate. While some enzymes are engaged in the breakdown of chemicals, others are involved in the synthesis or modification of other molecules (anabolism).

Thus, the ideal selection is option A.

Main sequence, red giant, white dwarf.

Explanation:

The life cycle of the sun is called as solar cycle and is the phase of solar development. There are about seven-stage in its life cycle. Starting with the birth of the sun that is found in the solar nebula theory took place about 4.56 billion years.  The sun starts to enter the T Tauri stage, followed by the main sequence stage where the sun is currently in. After this stage that is when the sun runs out of hydrogen from its core.  It will produce violent helium flashes and will shrink its size. When this happens it will reach the tip of the red giant stage. Later on, the naked core will form into a white dwarf.
