Explain why the forest ecosystem is a system.
Answer:
Like all ecosystems, forests consist of many interacting parts. They include living organisms such as plants, animals, and fungi. Forests also include non-living components that these organisms depend on, such as the soil and climate. As stated in the article, one change, such as pollution, can cause a ripple effect through the ecosystem. Dying lichens are one of the earliest signs of pollution. In turn, the loss of the lichens can cause a decline in species that rely on the lichens for survival.

That is the sample answer.

Three gel cubes similar to those from the previous
screens have been placed in a colored solution that
seeps into the gel much like nutrients enter a cell.
Use the slider to see how the solution affected the
gel cubes after some period of time.
2. How does this model support the conclusion that
cells need to have a high amount of surface area
relative to their total volume?
Answer:
These gel cubes can be thought of as representing individual cells. As the cubes interact with their surroundings based on the amount of surface area and volume they have, the efficiency movement of substances in and out of cells depends on the two attributes as well. Greater surface area will mean more efficient rates of diffusion, which implies a smaller surface area to volume ratio is ideal for a biological cell.
Hope that answers the question, have a great day!
After some period the gel cubes will become Turgid
The higher the surface area the more efficient The diffusion rate
When The gel cubes are placed inside a colored solution the solution will start seeping into the gel cubes as the gel cubes continues to remain in the colored solution. Hence the gel cubes will become Turgid after some period of time.
The surface area to volume ratio plays a major role in the rate of diffusion of solvents inside the gel cubes ( cell ). Therefore the higher the surface area to volume ratio, the more efficient diffusion rate the cells would have.
Hence we can conclude that After some period the gel cubes will become Turgid The higher the surface area the more efficient The diffusion rate

А __ is an agent that can cause infections and diseases.
Explanation:
I think it would be easier if u have options but I will help as much as I know abt this.. so The agents that cause disease fall into five groups: viruses, bacteria, fungi, protozoa, and helminths (worms). Protozoa and worms are usually grouped together as parasites, and are the subject of the discipline of parasitology, whereas viruses, bacteria, and fungi are the subject of microbiology.

Explanation:
During mitosis, the original cell produces two daughter cells. How many daughter cells will be produced if 250 mouse cells undergo mitosis?
Answer:
There would be 500 daughter cells if 200 mouse cells went through the process of mitosis. (If that's what your asking)
Explanation:
During mitosis, the organism (which would be an asexual producer) doubles the amount of chromosomes and they divides the doubled number by two. So the organism will always end up with two daughter cells with the same number of chromosomes as itself. (That is the way with asexual producer's-their offspring is always an exact replica of the first). Now, if you take one mouse, it would end up with 2 daughter cells. If 250 mice reproduce, each with two daughter cells, then there would be 500 daughter cells in total, because you would multiply 2 by 250.
The number of daughter cells that will be produced is; 500 daughter cells
Mitosis is a process of cell replacement or cell growth whereby a cell divides into two exact daughter cells containing the same number of chromosomes each as the number of chromosomes contained in the parent cell.
Given that the original cell produces two daughter cells, when 250 mouse cell undergoes this process we will have
250 * 2 = 500 daughter cells.
Hence we can conclude that the number of daughter cells that will be produced is 500 daughter cells

What is currently happening with Mount Etna?
Answer:
As Italy’s National Institute of Geophysics and Volcanology (INGV) explains on a recent blog post, the nascent eruption began on the night of May 29. Starting off by producing a thick column of ash rising from the New Southeast Crater, it gave way on May 30 to a far more lava-heavy display in the area, featuring two fissures blenching out lava.
Answer:
There is currently no eruptive activity at the volcano involving fresh lava and monitoring signals do not suggest an immediate change likely; only a weak thermal anomaly continues to be present from the southeast crater complex.

A cell has a 1% salt concentration. It is placed into a solution containing a 10% salt concentration.
What will happen to the cell?
Choose 1 answer:
Water will move out of the cell, causing it to swell.
Water will move into the cell, causing it to shrink.
Water will move into the cell, causing it to swell.
Water will move out of the cell, causing it to shrink.
Answer:
Water will move out of the cell, causing it to shrink.
Explanation:
When something with a low salt concentration is placed in a higher concentration of salt, the salt in the solution will try to suck out the water in the cell. Just remember why we hate salt, because it sucks! There's a little joke to help u remember. Thanks, Ms. Hoj :)
Answer:
CORRECT (SELECTED)
Water will move out of the cell, causing it to shrink.
Explanation:
The cell has lower concentration of solute and a higher concentration of water than the solution it is placed in. This means that water will move out of the cell, causing it to shrink.
