Answer:
Carbon is an element that is essential to all life on Earth. Carbon makes up the fats and carbohydrates of our food and is part of the molecules, like DNA and protein, that make up our bodies. Carbon, in the form of carbon dioxide, is even a part of the air we breathe. It is also stored in places like the ocean, rocks, fossil fuels, and plants.
The carbon cycle describes the flow of carbon between each of these places. For example, carbon continually flows in and out of the atmosphere and also living things. As plants photosynthesize, they absorb carbon dioxide from the atmosphere. When plants die, the carbon goes into the soil, and microbes can release the carbon back into the atmosphere through decomposition.
Forests are typically carbon sinks, places that absorb more carbon than they release. They continually take carbon out of the atmosphere through the process of photosynthesis. The ocean is another example of a carbon sink, absorbing a large amount of carbon dioxide from the atmosphere.
Some processes release more carbon dioxide into the atmosphere than they absorb. Any process that uses fossil fuels—such as burning coal to make electricity—releases a lot of carbon into the atmosphere. Raising cattle for food also releases a lot of carbon into the atmosphere. These processes that release carbon into the atmosphere are known as carbon sources.
Ideally, the carbon cycle would keep Earth’s carbon concentrations in balance, moving the carbon from place to place and keeping atmospheric carbon dioxide levels steady. However, the carbon cycle is changing because of human activity. People are releasing more carbon into the atmosphere by using fossil fuels and maintaining large livestock operations. Deforestation is depleting Earth’s supply of carbon sinks. As a result, the amount of carbon in the atmosphere is rising.

Answer:
Because the leaves contain a greater concentration of green chlorophylls than yellow and orange carotenoids.
Explanation:
Chlorophyll and carotenoids are both pigments found in the cells of organisms like plants. They have differing color range depending on which wavelength of light they absorb and which they reflect. For example, chlorophyll pigment are green because they reflect green light and absorb others.
According to this question, the leaves of most plants contain yellow and orange carotenoids in addition to green chlorophylls but leaves are mostly green. This is because there is an abundant of chlorophyll pigment than any other pigment in the leaves of most plants. Hence, GREEN COLOR conferred by chlorophyll dominates and masks the color appearance of the other accessory pigments like yellow and orange carotenoids.
Answer:
(<u>Bone deposition</u>),
<u>(Bone resorption</u><u>)</u>,
<u>Remodeling</u>
<u>Periosteal</u><u> </u>,
<u>Nedosteal,</u>
<u>The compact bone, </u>
<u> Spongy bone.</u>
Explanation:
The constant, dynamic process of continual addition of new bone tissue (<u>bone deposition</u>) and removal of old bone tissue (<u>bone resorption</u>) is a process called bone <u>remodeling</u>. This ongoing process occurs at both the <u>periosteal</u> (outer) and<u> nedosteal </u>(inner) surfaces of a bone.
It is estimated that about <u>nedosteal</u> of the adult human skeleton is replaced yearly. This process does not occur at the same rate everywhere in the skeleton. For example,<u> the compact bone</u> in our skeleton is replaced at a slower rate than the <u>spongy bone.</u>
Answer:
One reason is that there was too much pressure in the bottom of the ocean, from all the water pressing together.
