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.
Answer:
<u>Option- </u> Passive transport.
- The movement or transport of medium across an area or membrane on the basis of there concentration is termed to be the main mechanism for providing all the vital resources for the cell and tissue survival inside the body.
Explanation:
- Osmosis involves the movement of water molecules across a cell membrane. Diffusion involves the movement of substances other than water across a cell membrane. In both of these processes, substances move from an area of high concentration to an area of low concentration. Thus, both diffusion and osmosis are forms of <u>Passive transport.</u>
The correct answer is letter B, burning wood. This is not a renewable resource of energy as its by-product involves the release of greenhouse gases that can still be harmful to the atmosphere or to the environment in general. All the other choices are good sources of renewable power because they harness the power of naturally occurring materials found in their space.
Answer:
<u>True</u>
Explanation:
In cells, energy is obtained from food through the process of cellular respiration. In mitochondria, this occurs through aerobic respiration- here, cells breakdown sugars like glucose into carbon dioxide and water and energy in the form of ATP or adenosine triphosphate.
In cellular aerobic respiration:
C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP
Answer:
option B) The oxygen end of the molecule has a partial negative charge and the hydrogen end has a partial positive charge.
Justification:
The electronegativity of an element accounts for its relative ability to attract electrons.
Being oxygen more electronegative than hdyrogen (the electronegativity of oxygen is 3.44 while the electronegativity of the hydrogen is 2.20), the electron density will be displaced toward the oxygen, letting it with a partial negative charge and the hydrogen with a partial positive charge.
Finally, since the charge is not symmetrical distributed around a center of the molecule, the molecule ends being polar.
