Answer:
The correct answer is -
1. into the sac
2. in beaker hypotonic, in sac hypertonic
Explanation:
Osmosis is the diffusion of the solvent of a solution to the higher solute concentration through the semipermeable membrane. This membrane allows the water or solvent movement from the low solute concentration to high solute concentration and makes the cell or the sac bloated or turgid.
In this case, 2% slat concentration is dissolved in water which has low solute concentration in comparison of the sac which has 10% solute concentration so the outside the sac hypotonic solution present which allows the solvent to move from outside into the sac.
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

A.It shows how the pressure of a substance changes when heated.
B.It shows how the temperature of a substance changes when heated.
C.It shows how the volume of a substance changes when heated.
D.It shows how the mass of a substance changes when heated.
Answer:
B
Explanation:
A heating curve is a plot or graph wherein a substance is subjected to increasing temperature against time to measure the amount of energy it absorbs and changes state with increasing temperature. ... Nevertheless, a plateau is reached when the substance reaches melting point, i.e. changing from solid to liquid.

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.

(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

. During which part of the cell cycle does the cell divide?
Answer:
The part of the cell cycle in which the cell divides is called mitosis.
Explanation:
Mitosis, or M phase of the cell cycle, is where the somatic cell divides to obtain two daughter cells identical to the original. Mitosis is divided into four phases, known as prophase, metaphase, anaphase and telophase.
Literally, cell division into two daughter cells or cytokinesis occurs in the last phase of mitosis, telophase, since in the other phases cell nucleus division and chromosome distribution occurs.
The other major part of the cell cycle is known as the interphase, in which the cell prepares for division in the M phase.
