Answer:
A
Explanation:
The active state of cell division covers the prophase, metaphase, anaphase, and telophase. The total number of observed cells that were undergoing cell division can, thus, be calculated by adding the number of cells in each stage of the cell division.
Total number of cell in division = 20+4+2+4
= 30
Probability that a randomly chose cell will be undergoing cell division = number of cells in division/total number of cells
= 30/200
= 0.15 or 15%
The correct option is, therefore, A.
After running a chemical test of the contents of a human cell, Dr. Rogers cannot find any pyruvate molecules. He correctly determines that
The cell needs more water
The electron transport chain works too fast
Fermentation is occurring
Glycolysis is not occurring
Answer:it’s the last one
Explanation:
He correctly determines that Glycolysis is not occurring. So, the correct option is (D).
What is Glycolysis?Glycolysis is defined as the metabolic pathway which converts glucose to pyruvate. The free energy released in glycolysis is used to form the high-energy molecule Adenosine Triphosphate (ATP) and the reduced Nicotinamide Adenine Dinucleotide. This is a sequence of ten reactions which is catalyzed by enzymes.
This is the series of reactions which extract energy from glucose by splitting it into two three-carbon molecules known as Pyruvates.
The main function of glycolysis is to provide pyruvate for the another cycle known as TCA cycle. This glycolytic production of pyruvate reduces the cytosol by increasing the ratio of NADH [a reduced form of NAD+ (nicotinamide adenine dinucleotide)] to NAD+.
Thus, he correctly determines that Glycolysis is not occurring. So, the correct option is (D).

After swimming in the pool for 2 hours, your friend starts to complain because his fingers and toes are wrinkled. Use the concept of osmosis to explain why. Be sure to include the following in your explanation: The terms hypotonic, isotonic, and/or hypertonic (as well as what they mean) • The overall direction of water movement and reason why • How the movement of water causes his fingers and toes to change • A picture if necessary
Answer:
Explanation:
Osmosis is the spontaneous movement of molecules from low concentration to high concentration. The finger is hypertonic to the swimming pool, which means that it has a higher osmotic pressure. The pool is hypotonic to the finger, which means it has a lower osmotic pressure. Because osmosis goes from low to high concentration, water will seep into the finger, causing it to swell and become wrinkly. This balances out the concentration on both sides of the semipermeable membrane (skin on the finger) and makes them isotonic, meaning they have the same concentration.

9. What is the measure of H+ in a solution called? What is the value for water? What numbers are acidic and which ones are basic? You live in a one story house made entirely of redwood. What color would the stairs be?
Answer:
8. An Acid and a Base.
7. A solvent is a substance that dissolves a solute, resulting in a solution (able to dissolve other substances). A solute is the dissolved matter in a solution. The key difference between solvent and solute is that the solute is the one to be dissolved while, the solvent is responsible for dissolving it.
6. Homogeneous solutions are solutions with uniform composition and properties throughout the solution. Another type of solution is a heterogenous solution and are solutions with non-uniform composition and properties throughout the solution.
5. A mixture is composed of two or more substance, but they are not chemically combined.
Polarity allows the development of functional complexity, not only in multicellular organisms, but also in cells and in subcellular structures

Which of the following ph values indicates a solution with the highest concentration of hydrogen ions
Answer:
1,2,3,4,5 and 6.
Explanation:
If a solution having pH values such as 1,2,3,4,5 and 6 indicates that the solution has the highest concentration of hydrogen ions because below pH 7 the concentration of hydrogen ions increases and the solution tends to more acidic. Highest concentration of hydrogen ions are present in a solution having pH 1 and when the pH value increases from pH 1, the concentration of hydrogen ions decreases.

how did changes in earth's atmosphere allow for the evolution of life on earth?
Answer:
The early atmosphere was probably mostly carbon dioxide, with little or no oxygen. There were smaller proportions of water vapor, ammonia, and methane. As the Earth cooled down, most of the water vapor condensed and formed the oceans.
If a cell normally has 32 chromosomes, what would be the results of going through mitosis?
Answer:
For mitosis, the DNA content of the daughter cells and the mother cell will always be identical. Since the number of cells have doubled, so has the DNA. The 16 chromosomes in the mother cell will be duplicated, then the duplicates split and evenly divided into the daughter cells. The 16 chromosomes in each daughter cell will be non-duplicated at first.

Well now check yourself please
Chloroplasts would have more access to light energy to convert carbon dioxide and water into glucose, benefiting photosynthesis. So the correct option is D.
What is a central vacuole?
A core vacuole that is hydrated. This organelle, which is surrounded by a single membrane, serves as a reservoir, waste disposal site, storage area, and even a way to maintain the cell's form. When the vacuole is completely filled with water, it pulls the cytoplasm into a narrow strip next to the membrane and expands like a balloon filled with water.
This turgor pressure maintains the cell's rigidity and gives plant structures like leaves their distinctive shapes. Long-term dehydration of a plant causes the central vacuoles to lose water, the cells to deform, and the entire leaf to wilt. In the vacuole, plants frequently store carbohydrates, ions, certain proteins, and sporadically pigments.
For instance, the pigments created and deposited in the central vacuole give flower petal cells their distinctive hue. In addition to making the plant poisonous to herbivorous animals, poisonous substances that might injure the cytoplasm are discharged into the vacuole.
Therefore, the correct option is D.

A cart accelerates at 2 m/s2 when a force of 60 N is applied. What is the mass of the cart? (Formula: F=ma)
0.03 kg
30 kg
62 kg
120 kg
Answer:
30 kg
Explanation:
Since a force of 60 N is applied, the mass of this cart is equal to 30 kg.
Given the following data:
Acceleration = 2 [tex]m/s^2[/tex]
Force = 60 Newton.
How to calculate the mass of this cart.From Newton's Second Law of Motion, the force exerted on the cart is given by this formula:
[tex]F=ma[/tex]
Where:
F is the force.m is the mass.a is the acceleration.Making mass the subject of formula, we have:
[tex]m=\frac{F}{a}[/tex]
Substituting the given parameters into the formula, we have;
[tex]m=\frac{60}{2}[/tex]
m = 30 kg.
