Answer:
Both are processes that are the result of stem cell division
Explanation:
Self-renewal and differentiation are the property of the stem cells. Both the processes result from stem cell division. Thus, option A is correct.
What are stem cells?Stem cells are the special cells that can produce other types of cells from differentiation. For example, the Hematopoietic Stem Cells give rise to the blood cells that can be RBC, WBC, etc.
Differentiation is the process where the less specialized cells give rise to a more specific cell type. The stem cells also undergo self-renewal where the same cell type is also produced.
Therefore, both process results from stem cell division.

(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
Does anyone know if these are correct, I’m just asking because idk if they are correct or not.

which of the following would be considered a quantitative observation
a ) the attractiveness of the tail of male peacocks is compared
b ) butterfly wings are assessed to see which is the most orange in appearance
c ) the height of radish seedlings is measured
d ) the odor of different plants is compared to see which smells the worst
Answer:
c ) the height of radish seedlings is measured
Explanation:
The quantitative observation from the given choices is the height of the radish seedling measured.
Observation is one of the most important steps in the scientific method. It is usually carried out with our six senses. Also, observations can be made with very specialized equipment.
Taking note of color, odor, etc are all qualitative observations.
Quantitative observations are taken for measurements.

If energy is released, free energy must be what?
Answer:
If energy is released during a chemical reaction, then the change in free energy from the conversion of the reactants to the products, signified as ΔG (delta G) will be a negative number.
Explanation:
Hope it helped!
Answer:
If energy is released during a chemical reaction, then the resulting value from the above equation will be a negative number. In other words, reactions that release energy have a ∆G < 0. A negative ∆G also means that the products of the reaction have less free energy than the reactants because they gave off some free energy during the reaction.

What are some fun facts about Newton's second law of motion.
Answer: When you kick a ball, forces start to act on it immediately. These include resistance or friction from the air and gravity. Gravity pulls the ball down to the ground and the air resistance slows it down. The second law states that the greater the mass of an object, the more force it will take to accelerate the object.
Explanation:
Many different types of mutations can occur within the body. An individual experiences a mutation that changes a base in
a mRNA strand, but during translation the mRNA strand still creates the same protein. Which type of mutation is
responsible for the change in the mRNA base?
A.silent
B.missense
C.nonsense
D.insertion
Answer:
A. Silent, The type of mutation responsible for changing a base in the mRNA strand, without changing the coding aminoacid or protein, is called a silent mutation.
Explanation:
In a silent mutation occurs the change of a nitrogenous base in one of the codons that encodes an aminoacid, without changing the aminoacid or altering the structure or function of the protein to be synthesized.
In this type of mutations the change of the base does not mean the change of the aminoacid, because some aminoacids can be coded with more than one codon. In the case of Leucine, the codons that encode it are CUU, CUC, CUG or CUA, so even if a base changes, the final protein will be the correct one.
For the other options:
Missense: the change of the base in the DNA chain implies the change of the codon in the mRNA and of the encoded aminoacid, in that way a structural and functional alteration of the synthesized protein occurs. Nonsense: the change in the nitrogenous base in the DNA leads to the coding of a termination codon, so that the protein is ultimately incomplete. Insertion: in this case there is the addition of more nitrogenous bases to the DNA chain, with respect to the original one.Answer:
Silent

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.

The greenhouse effect is caused by ______.
a buildup of carbon dioxide in the atmosphere
the trapping of the sun's heat
pollution from burning fossil fuels
all of the above
Answer:
all of the above im pretty sure
Explanation:
The greenhouse effect is caused by a buildup of carbon dioxide in the atmosphere, the trapping of the sun's heat and pollution from burning fossil fuels.
What do you mean by green house effect?The greenhouse effect is a process that occurs when energy from a planet's host star goes through the planet's atmosphere and heats the planet's surface, but greenhouse gases in the atmosphere prevent some of the heat from returning directly to space.
The greenhouse effect is the way in which heat is trapped close to Earth's surface by “greenhouse gases.” These heat-trapping gases can be thought of as a blanket wrapped around Earth, keeping the planet toastier than it would be without them.
One example of the greenhouse effect that most of us experience in everyday life is the warming of a car's interior when the vehicle is left out in the sun.

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.
