(AKS 3b / DOK 2) Four students were discussing how surface area to volume ratio limits cell size. Which student claim below would be the
BEST claim to support?
O A. Student 1: The larger the cell, the more nutrients it will receive in a shorter amount of time
B. Student 2: As the cell gets bigger, the outside of the cell is able to keep up with its internal needs
OC. Student 3: Waste diffuse out of the larger cells faster than smaller cells
D. Student 4: The bigger the cell gets, the less surface area it has for its size
Answer:
D
Explanation:
Let's assume there's two cuboidal cells, cell A and B
Cell A has a side of x
Let's find the surface area of cell A
SA = 6(L²)
SA = 6(x²)
SA = 6x²
Let's find the volume of cell A
V = L³
V = (x)³
V = x³
Cell B has a side of 2x
Now let's find the surface area of cell B
SA = 6(L²)
SA = 6(2x)²
SA = 24x²
Let's find the volume of cell B
V = (L)³
V = (2x)³
V = 8x³
As you can see, just by doubling the side length, the ratio between Surface Area and Volume went from 6/x to 3/x (the x² in the numerator and the x³ in the denominator cancel out forming 1/x)
The ratio decreased, therefore, D is the statement that makes sense
What happens when a chlorine atom gains an electron in its outer energy shell?
A. It becomes a negative ion.
B. It has a decrease in the number of neutrons.
C. It becomes a positive ion.
D. It has an increase in the number of protons.
Answer: A.
Explanation: When a chlorine atom gains an electron, its outermost principal energy level achieves an octet. In this case, the ion has the same outermost shell as the original atom, but now that shell has eight electrons in it.
Answer:
A
Explanation:
When a element gain a electron it is nation as it is now negatively charged

The conversion of stored potential energy into kinetic energy can also be harnessed to power homes, factories and entire cities. Which example from the text supports this conclusion?
Answer:
The conversion of stored potential energy into kinetic energy can also be harnessed to power homes, factories and entire cities. The most notable example is the Hoover Dam. The Hoover Dam is an arch-gravity dam by design. This design name is the first clue as to how exactly the dam harnesses energy.
What is the difference between near surface ozone and high altitude ozone?
The difference between near-surface ozone and high altitude ozone is that high altitude ozone is adequate ozone as it is a UV shield and the surface zone is destructive ozone as it is harmful to life forms.
What are the major reasons responsible for ozone depletion?The major reasons for ozone depletion include the excessive accumulation of greenhouse gases, CFCs, propellents, manufactured chemicals, etc.
High altitude ozone is found at the topmost height in the region of the stratosphere, while surface ozone is found just above the troposphere.
Therefore, it is well described above.

Hi, so i was wondering How long does Mars have to travel around Earth to make it's complete rotation?
Answer:
24 hours and 37 minutes
Explanation:
At Mars' orbital speed of 24 km per second, it takes the planet 24 hours and 37 minutes to complete one rotation. That is just a little more than a day on Earth.
Answer:
The Earth zips around the Sun at about 67,000 miles per hour, making a full revolution in about 365 days – one year on Earth. Mars is a little slower, and farther from the sun, so a full circuit takes 687 Earth days – or one Mars year.

What will happen to a cell in a hypertonic solution where osmosis is occurring?
Answer:
If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, the relative concentrations of solute and water are equal on both sides of the membrane. There is no net water movement, so there is no change in the size of the cell.

Environmental scientists collect air samples so they can test the quality of the air. They start with rigid metal containers that are completely empty the air has been popped out of them. What happens to the pressure inside the container and the volume of the container as air enters it?
Answer:
The air popped out of the empty rigid metal containers because the pressure inside the container is high.
This is so because as air enters the container it tries to spread out and its volume increases as particles started occupying the empty space. With the occupying volume of particles, the air particles move faster and hit the container harder that increases the pressure inside the container, and air-popped out.
