Answer:
With each heartbeat, the heart sends blood throughout our bodies, carrying oxygen to every cell. After delivering the oxygen, the blood returns to the heart. The heart then sends the blood to the lungs to pick up more oxygen.
Explain how a carbon atom from a CO2 molecule in the air can end up as a carbon atom in a protein in a plant cell
Answer:
Photosynthesis and metabolism are among the most complex areas in biology so given the nature of this forum I've kept the answers simple and brief.
Carbon is of central importance to all biological systems due to its special bonding properties allowing it to form various bonds with other atoms and produce a wonderfully complex range of molecules used by life.
In photosynthesis inorganic carbon in carbon dioxide gas is fixed to hydrogen to produce sugar, an organic molecule. In this case the carbon gains electrons so it is 'reduced' and this process requires energy in the form of light. Once in sugar form, the process can be reversed and the carbon can be oxidised back into carbon dioxide during cellular respiration, releasing energy.
So in photosynthesis, the carbon from carbon dioxide is reduced to form a sugar molecule. When transitioning to respiration, the carbon in the sugar is oxidised to form carbon dioxide again in the reverse reaction to photosynthesis.
The carbon is transferred between molecules through various intermediate steps during these processes, involving enzymes (biological catalysts) to assist in cleaving specific bonds at each stage. During cellular respiration (an energy release reaction) as the carbon is successively oxidised electrons are liberated that are used as part of the energy release. These electrons are captured or 'carried' by special organic molecules called NAD and FAD (reducing them) which in turn can then be oxidised to produce the universal energy currency of life: ATP molecules. ATP is a small bio molecule containing a high energy phosphorous bond that can be broken to release energy to do cellular work. It is used by all life that we know of and is the ultimate product of cellular respiration.
The carbon atom in a CO₂ molecule in the air can become a part of the
cellulose molecule in a plant by the carbon dioxide molecule reacting with the water during photosynthesis to form Glucose.
This formula can use for the reaction: 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
The glucose molecule formed is then translocated to other parts of the
plants which are such as the roots and stems and help in the formation of cellulose.
Also, aThis is basically how the carbon atom in carbon dioxide becomes a cellulose molecule.Learn more about:

In which situation would artificial insemination most likely be used over other forms of treatment?
Artificial insemination can be used when there is a case of infertility.
This process lets the sperm skip the cervical mucus entirely . doctors often use this process when the reason for the couple’s infertility is unclear.
In case of endometriosis, this process is helpful in mild or moderate cases of endometriosis.

16. In the process of digestion, food gets ready to exit the body. Which is another body system that aids in waste removal?
A. Excretory
A. Excretory
B. Endocrine
B. Endocrine
C. Skeletal
C. Skeletal
D. Nervous
Answer:
A) Excretory
Explanation:
A good way to remember is Ex - like exit so it will leave the body.
Answer:
A. Excretory
Explanation:
Bile is stored in the gallbladder until it is needed. The pancreas makes enzymes that help digest proteins, fats, and carbs. It also makes a substance that neutralizes stomach acid. These enzymes and bile travel through special pathways (called ducts) into the small intestine, where they help to break down food.

What was the general pattern of population growth in the greater Atlanta area, from 1990 to 2000
Answer:
Positive growth.
Explanation:
The general pattern of population growth in the greater Atlanta area from 1990 to 2000 is positive means there is increase occur in the population. The population of greater Atlanta in 1990 is 2,184,000 while on the other hand, the population of Atlanta is 3,522,000 in the year 2000. So there is 1,338,000 people increase occur in 10 years of duration from the year 1990 to 2000. So we can conclude that the pattern of population is positive and upward.

how magnification and resolution affect the appearance of objects viewed under a microscope
Answer:
It allows to see objects more clearly.
Explanation:
Magnification and resolution greatly affects the appearance of objects that can be seen under a microscope because these two things make the specimen enlarge in size. Magnification refer to the process of enlarging the apparent size of something to see and observe it clearly while on the other hand, resolution is used to see more details about specimen that can be study in the microscope so we can conclude that both magnification and resolution has a great impact on the appearance of objects.
how most of our excretory system is not dedicated to excreting; it’s dedicated to reabsorbing.
Answer:
Not all animals use the same routes or excrete their wastes the same way humans do. Excretion applies to metabolic waste products that cross a plasma membrane.
The excretory system works with the respiratory, endocrine, urinary and digestive system. It works with the respiratory system because it helps the lungs get rid of carbon dioxide and water vapors. It works with the digestive system to help get rid of wastes that you eat through the anus.
What is the volume of a square pyramid with a base edge of 14 m and a slant height of 25 m
Answer:
length of base(l) = 14m
slant height (s)=25m
we know,
slant height(s)=√(l/2)^2 + h^2
or, 25= √(14/2)^2+ h^2
or, 25 = √49+h^2
or, 25^2 = 49+h^2
or, 625 = 49 + h^2
or, 625-49=h^2
or, √576 =h
h=24
Therefore vertical height (h)= 24m
Again,
Volume of square pyramid (v) = 1/3 L^2h
or, v =( 1/3) 14^2×24
or, v= 4704 / 3
Therefore, V= 1568 cubic meter.
