Osmosis passes from a medium with a high concentration of water molecules to another with a low concentration of water molecules and since the potato has low water concentration so the water transfers to it increasing its mass
The mass of each potato cube increased because they have gained water by osmosis.
Recall that: osmosis is the movement of water molecules from the region of high water concentration (high water potential) to the region of low water concentration (low water potential) through a semipermeable membrane.
A solution with a high solute concentration will have low water potential and vice versa. They are also said to be hypertonic when compared to a solution with a low solute concentration (hypotonic).
Thus, the potato cubes increased in size because the cells of the potato have low water potential when compared to the distilled water in which they were thrown. In other words, the cell sap of the potato cubes is hypertonic while the distilled water is hypotonic.

How is the age of the earth used as evidence of evolution?
Answers
Answer:
Explanation:
All radiometric evidence points to the age of the Earth as about 4.54 billion years old. The old age of the Earth is evidence for evolution, a change in the genetic makeup of a population over time.
Answer:
The age of the earth can be used as evidence of evolution because it withholds the past that we are capable of uncovering bit by bit. We excavate fossils buried in the ground which we use accordingly. The fossil record reveals that the deeper you go, the farther back in history you unearth. This is known as the Law of Superposition. With these fossils, we can compare and contrast the anatomy of closely related organisms and possibly uncover vestigial structures. All of which is evidence that evolution has taken place.

A scientist performed an experiment during which she measured the energy transferred in each step of her experiment. The total quantity of energy transferred in all of the steps was less than the amount she measured at the beginning. What is the most likely explanation for this result?
Answers
Answer:
Option D
Explanation:
The complete question is
A scientist performed an experiment during which she measured the energy transferred in each step of her experiment. The total quantity of energy transferred in all of the steps was less than the amount she measured at the beginning. What is the most likely explanation for this result?
a) Energy was destroyed during certain steps in the experiment.
b) The steps in the experiment required more energy than was available
c) The experiments created energy that was then used up at a faster rate.
d) Some energy was transformed into unwanted heat or sound that was not detected
Solution -
Option D is correct
While transfer of energy through any medium, some energy is lost in the form of heat and light. This loss of energy is not accounted at the beginning of the process and hence the initial energy loss was zero. With the succession of the process energy kept loosing and hence the final energy count was low at all steps.
Which of the following statements explains the importance of enzymes that check for and repair mistakes during DNA replication?
A
The enzymes replace the DNA with RNA
B
The enzymes speed up the rate of RNA synthesis.
C
The enzymes prevent many genetic mutations from being expressed
D
The enzymes remove many recessive gene copies from the nucleus.
Answers
Answer:
C!!
Explanation:
The statement explains the importance of enzymes that check for and repair mistakes during DNA replication is the enzymes prevent many genetic mutations from being expressed. Thus, the option C is correct.
What is RNA polymerase?RNA polymerase is an enzyme that aids in the transcription of DNA into RNA during transcript in the nucleus. The enzymes prevent many genetic mutations from being expressed.
Primase is an enzyme that synthesizes short RNA sequences called primers. These primers serve as a starting point for DNA synthesis during replication as the DNA polymerases cannot begin the synthesis of the new strand, they only extend it after primase begins it and primase produces RNA molecules, the enzyme can be said to be a type of RNA polymerase.
Therefore, The statement explains the importance of enzymes that check for and repair mistakes during DNA replication is the enzymes prevent many genetic mutations from being expressed. Thus, the option C is correct.
