Many small freshwater organisms have a structure called a contractile vacuole, which pumps water out their body. Explain how this process is an example of active transport.
Answer:
1: The process of osmosis would cause water to move into the cells causing them to swell and possibly burst. Many freshwater one celled organisms have structures called contractile vacuoles. These structures collect and pump out excess water that accumulates in the cell.
2: During active transport, a protein pump uses energy, in the form of ATP, to move molecules from an area of low concentration to an area of high concentration. An example of active transport is the sodium-potassium pump, which moves sodium ions to the outside of the cell and potassium ions to the inside of the cell.

HELP ASAP PLEASE!! DUE IN 10 MINUTES !!! based on these results which statement correctly predicts what will happen to red blood cells when they are placed in a beaker containing a water solution in which the salt concentration is much higher than the salt concentration in the red blood cells
A:the red blood cells will absorb water and increase in size
B:the red blood cells will lose water and decrease in size
C:red blood cells will of first absorb water than lose water and maintain their normal size
D:the red blood cells will first lose water then absorb water and finally double in size
Answer:
The correct answer is - option B. the red blood cells will lose water and decrease in size.
Explanation:
The movement of the water takes place always from the high concentration region of solute to the low concentration of solute through a semi-permeable membrane. In this case, the representation is showing that placing the cell inside a solution with low concentration solute than the cell makes the cell increase the size, and placing it in a solution high concentration of solute makes it decrease in size due to the transfer of water from more water to the low water area.
Now placing the RBC in a solution with more salt concentration than the cell makes the solution hypertonic which means the solution has more solute concentration and less water so the water move from cell to the solution and cell will shrink and decrease in size.

Which of these is one characteristic of topographic maps? A mountain peak. B location of a ravine. C steepness of a slope. D distance between two areas.
Steepness of a slope (C) is one characteristic of topographic maps.
"The more closely spaced the contour lines, the steeper the slope. You can find out exactly how steep the slope of the area you are interested in by subtracting the lowest elevation from the highest, and dividing the result by the horizontal distance."
5. Studying light from a star allows us to… a. determine a star's temperature b. determine what elements the star is made of c. determine how a star is moving (toward, away, fast, slow) d. all of these e. none of these
Answer:
The correct answer is option C "determine how a star is moving (toward, away, fast, slow)"
Explanation:
All realized components emanate and assimilate specific frequencies of light, which is important for the electromagnetic range. By considering the frequencies of light (as demonstrated by 'lines' inside the electromagnetic range) discharged by an object in space, astronomers can get a scope of information.
One thing they look at is the adjustment in situation of lines in the range from a star this can tell astronomers the distance away the star is, regardless of whether it is moving towards or away from us and how quick it is moving.
Newton's first law of motion states that an object will remain in motion in a straight line unless compelled to change direction by an external force.
Explain why satellites launched into orbit do not continue moving in a straight line. Make a connection between satellites and planets.
Explanation:
When satellites are launched into orbit, they are able to orbit around planets due to the gravitational force of attraction between the satellite and planet (usually there is no apparent change in motion of the planet because of its relative huge size than the satellite)
This gravitational force is in a different direction than the satellite's motion, therefore it keeps it orbiting around planets and does not continue moving in a straight line.
Pls help I’m so confused :(
Answer:
Left is synthesis, right is digestion
Explanation:
Synthesis refers to the creation of a product, whereas digestion refers to the breakup of the reactant or initial substance.

By looking at this chart you can see that the codon CAC codes for histidine
What are the lines in leaves
Answer:
Veins – The blackish lines in the leaf blade are called veins. The largest black line is the leaf's single “midvein,” running from the petiole to the leaf tip, the smaller blackish lines branching off the midvein are “secondary veins”
Why do people feel fireworks before hearing it?
Answer:
People feel fireworks before hearing it because light travels faster than sound.
Explanation:
We always see the colors of the fireworks before hearing their defeaning sounds. This is because light travels faster than sound, so we can see the light before hearing the sound. An example of this is seeing lightning before hearing thunder. When lightning strikes, the air around it moves very quickly, causing vibrations.
