You are cleaning your room, when all of a sudden the smoke alarm goes off. You go into the kitchen and it is very smoky, so you inhale smoke. Your body has to immediately get rid of the carbon molecules you just inhaled. Explain all the parts of the cell involved in getting the smoke out of your cells.
Answer: The smoke goes to the cells of the mouth or buccal cavity, nasal cavity, trachea, larynx, and then finally distributed into the bronchi (small tubes) in the lungs.
Explanation:
Respiratory system can be defined as the complex system of organs that allow us to obtain oxygen for biochemical oxidation of food and releasing energy in the form of ATP. The breathing is a process in which the air is inhaled inside the respiratory system and oxygen is absorbed by the cells and carbon dioxide is expelled out of the body. The pathway of oxygen is cells of the mouth or buccal cavity, nasal cavity, trachea, larynx, and then finally, distributed into the bronchi (small tubes) in the lungs and it is reverse for carbon dioxide or carbon monoxide gas components present in the smoke. The red blood cells are the cells that are involved in getting rid of smoke out of the body, as they have hemoglobin which has binding efficiency with both oxygen and carbon dioxide. The exchange of deoxygenated blood (carbon dioxide containing blood) takes place in the blood capillaries. From the blood capillaries the carbon dioxide is expelled out from the bronchi following the entire route of expiration.

What are the properties of carbon atom?Carbon is found in almost all the biomolecules and majority of compounds present in the atmosphere. All the living things contain carbon in the form of different biomolecules. A single molecule of some compounds can contain up to thousands of carbon atoms including polymers which make up the cell wall and cell membrane.
Each carbon atom can form single bonds with up to four other carbon atoms. This is due to the valency of carbon which is four, thus it can form covalent bonds with other atoms or elements. This property of Carbon is known as tetravalency. Carbon has the ability to form long chains when it gets linked with other carbon atoms.
Each carbon atom can form double bonds with up to two other carbon atoms or more.
Therefore, all these statements are true.

because it contain moist environment or land filled with different minerals. Such type of climate is favourable for mostly all kinds of plants.
Different types of plant are available in riverside, lakeside because of the
presence of nutrients and resources in them.
Plants are regarded as primary producers which produce their food through
the process of photosynthesis. Photosynthesis involves reaction between
carbondioxide and water to form glucose.
The availability of water favors photosynthetic processes which is why plants are present in such areas to increase food production.

Increased sea surface temperature has the potential to kill vast areas of coral because of this phenomenon:
A.) invasive species
B.) coral bleaching
C.) ocean acidification
D.) oligotrophic
Answer:
B.) Coral Bleaching
Explanation:
Increased temperatures can cause coral to 'bleach' or lose their symbiotic zooxanthellae algae
Increased sea surface temperature has the potential to kill vast areas of coral because of the coral bleaching.
What do you mean by coral bleaching?Bleached coral Healthy coral Coral bleaching is the process when corals become white due to various stressors, such as changes in temperature, light, or nutrients.
When water is too warm, corals will expel the algae (zooxanthellae) living in their tissues causing the coral to turn completely white. This is called coral bleaching. When a coral bleaches, it is not dead.
Coral bleaching can be caused by a wide range of environmental stressors such as pollution, oil spills, increased sedimentation, extremes in sea temperatures, extremes in salinity, low oxygen, disease, and predation.

Which of these factors best explains why liquid water exists on Earth?
A. Presence of living things
B. Moderate temperatures
C. Lack of gravity
D. Lunar tides
The factor that best explains why liquid water exists on Earth is moderate temperatures. Therefore option B is correct.
Liquid water exists on Earth primarily due to the presence of moderate temperatures. Water is a unique substance because it has a relatively high boiling point and a wide range of temperatures at which it remains in a liquid state.
The average surface temperature of the Earth, along with the atmospheric pressure, allows water to exist as a liquid under normal conditions.
The lack of gravity is incorrect because gravity is essential for the existence of liquid water. Gravity keeps water molecules attracted to each other, preventing them from dispersing into the atmosphere.
