Answer:
As the radius of a cell increases, its surface area increases as the square of its radius, but its volume increases as the cube of its radius (much more rapidly). Therefore, as a cell increases in size, its surface area-to-volume ratio decreases.

Which of the following statements is true?
A.
Chemical reactions can only absorb thermal energy.
B.
Chemical reactions can neither absorb thermal energy nor release thermal energy.
C.
Chemical reactions can either absorb thermal energy or release thermal energy.
D.
Chemical reactions can only release thermal energy.
Answer: C. Chemical reaction absorb or release thermal (and sometimes other) energy
Explanation:
Chemical reactions can result in products with more or less chemical energy than the precursors. When products have less chemical energy, the excess is converted to heat (exothermic reaction)
When the products have more chemical energy, heat must be added to make up the difference (Endothermic reaction)
Fireworks are examples of exothermic reactions where the excess is released as thermal, mechanical, and radiant energy. A lit match releases thermal and radiant energy.
Respiration is also an exothermic reaction
C6H12O6 + 6O2 —> 6CO2 + 6H2O + energy
Respiration is the reverse of photosynthesis, an endothermic process. The overall photosynthetic reaction is 6CO2 + 6H2O + energy —> 6C6H12O6 + 6O2
In this case radiant energy drives the reaction.
The reaction 2H2O —> 2H2 + O2 is an endothermic reaction driven by electrical energy.
Many reactions are reversible and if one is endothermic, the reverse is exothermic e.g. 2H2 + O2 —> 2H2O +energy is the reverse of electrolysis of water, or respiration vs photosynthesis.

How many ATP are produced by the ETC?
A) 2
B) 4
C) 12
D) 32
Answer:
The electron transport chain or ETC for short has 34 ATP (Adenosine Triphosphate or the energy carrying molecule) Which has the molecular formula C10H12N5O13P3. So I would go with D because this is closest.
This is because one molecule of glucose in a Eukaryotic cell generates around 30 to 32 ATP.
Explanation:
The 34 ATP produced by ETC(Electron transport chain) or the electron transport stage produces the most ATP(energy carrying molecule) out of any stage in aerobic respiration/ cellular respiration cycle. While the krebs cycle, and Glycolysis produce 2 ATP each. Making the rest of the stages 30 ATP total.

Because most nerve cells do not typically undergo mitosis, they are generally not capable of which of the following?a.producing enzymesb.generating more nerve cellsc.performing cellular respirationd.transporting ions against a concentration gradien
Answer:
B. generating more nerve cells
Explanation:
Mitosis is the process whereby a cell divides into two genetically identical daughter cells. It is way through which living cells reproduce and multiply themselves.
Hence, a nerve cell that do not typically undergo mitosis will be incapable of replicating/multiplying itself, hence, unable to generate more nerve cells.

What would happen to the pressure inside any enclosures on the moon as the sun hits the exterior and the temperature begins to rise? What kind of safety features could be built in to accommodate this?
Answer:
The pressure inside any enclosures on the moon would increase in pressure when the temperatures rise. This problem could be solved by having a portion of the enclosures that is flexible and can expand out for the pressure to decrease as necessary.

HELP!Mariana eats an orange. Which statement describes the ultimate source of the energy that her body receives when she digests the orange?
Organic matter, rich soil in which the orange tree grows, and adequate water all work together to generate the energy that can be obtained from the orange.
The orange tree obtains energy from the nitrogen and other compounds in fertilizer.
The light energy that originates from the sun provides the energy to grow oranges, which contain macromolecules.
The orange contains the energy-rich nutrients that it draws from the soil.
Answer:
C.
Explanation:
The light energy that originates from the sun provides the energy to grow oranges, which contain macromolecules.
Please do not be upset if this is wrong.
The ultimate source of energy received by digesting orange is the light energy that originates from the sun provides the energy to grow the oranges, which contain macromolecules. Thus, the correct option is C.
What is the ultimate source of energy?The ultimate source of energy of the solar system is the Sun. It is the primary source of energy for the Earth. The sun is called the ultimate source of energy because it is the source of almost all energies of the earth.
With the help of solar energy, all the green plants (producers) produce food by the process of photosynthesis. In turn, animals eat plants and use the chemical energy for all the activities such as cellular activities.
Therefore, the correct option is C.

13) When mRNA is "processed", what are the pieces of mRNA that are cut out and stay in the nucleus?
Introns
Exons
Answer:
Introns
Explanation:
The coding region of the gene is the part of the gene that is transcribed. However, not all of the gene makes the final mRNA. There are sequences called exons and introns in the coding region of the gene.
The pre-mRNA contains transcribed sequences of both the introns and exons. However, the introns are removed from the final mRNA by splicing. The final mRNA that is translated to the protein only contains exons. An illustration is attached to illustrate this.
