Answer: -Carbon is interesting and important elements to life because it can form more compounds than any other element.
- Carbon is the most abundant element present in the human body and important for plant, animal life and for the atmosphere.
Explanation:
Why Carbon is so interesting? So let's start it here.
- *Diamond* the most precious jewel for anyone and costly too, made up Carbon and hardest as well.
- Not only this graphite also is a form of Carbon. Graphite is a good conductor of electricity.
- Coal and soot is also made up of Carbon and amorphous in shape.
-18% of the human body mass is because of Carbon.
- Plants use carbon dioxide during photosynthesis and it forms glucose and oxygen that animals are dependant on.
DNA Deoxyribonucleic acid complex molecule consists of Carbon.

Heart and lungs:</u></h2>
The upper chamber of the heart is called atrium and lower chamber of the heart is called ventricles.
The blood circulation in the heart is basically under the functioning of three blood vessels namely:
<h3><u>Arteries:
</u></h3>
- They start with the aorta, the huge vein leaving the heart.
- Veins divert oxygen-rich blood from the heart to the majority of the body's tissues.
- They branch a few times, decreasing and littler as they convey blood more remote from the heart.
<h3><u>Capillaries:
</u></h3>
- These are little; flimsy blood vessels that associate the arteries and the veins.
- Their dainty dividers permit oxygen, supplements, carbon dioxide, and other waste items to go to and from our organ's cells.
<h3><u>Veins:
</u></h3>
- These are the blood vessels that return blood to the heart; this blood needs (oxygen-poor) and is wealthy in waste items that are to be discharged or expelled from the body.
- Veins become bigger and bigger as they draw nearer to the heart.
- The unrivaled vena cava is the huge vein that brings blood from the head and arms to the heart, and the second rate vena cava brings blood from the mid-region and legs into the heart.
Ain't in ur following ig..wait, will follow u in a sec :) Then went be even Stephen (y do u want ppl to report it btw?)
Energy. A solute can only move against concentration gradients using active transport which requires energy
<span>A solution is the mixture of two or more substances. One of them is called the solute and the other is the solvent. A solute is the substance to be dissolved (sugar). The solvent is the one doing the dissolving (water). Therefore, suder is the solute and water is the solvent. Option C is the correct answer.</span>
