Answer:
In plant cells, osmotic pressure can cause changes in the size of the central vacuole, which shrinks or swells as water moves into or out of the cell.
Explanation:
Hope this helped, Have a Great Day/Night!!
Answer:
Function of the Central Vacuole
Turgor pressure changes in a cell due to osmosis, which is the diffusion of water into or out of the cell. When a plant cell is in a hypotonic solution, there is a higher concentration of water molecules outside the cell than inside, and water will flow into the cell.

An igneous rock has small, dark crystals. Which statement also accurately describes this rock?
It is an intrusive rock.
It has a coarse texture.
It was found on Earth’s surface.
It was formed from slow cooling.
Answer:
It was found on Earth’s surface.
Explanation:
Igneous rocks are formed either on the surface of the Earth or deep in the Earth's crust. Those formed on the surface of the Earth are called "Extrusive Igneous Rocks" while those formed in the crust are called "Intrusive Igneous Rocks."
An igneous rock which has small, dark crystals is an extrusive igneous rock (this makes the first choice incorrect). It was formed through "rapid cooling," thus, it's texture is fine (this makes the last two choices incorrect).
Since it is an extrusive igneous rock, it can be found on the Earth's surface. This makes the third choice correct.

Once the problem has been identified, observations have been made, and research has been completed to learn about a problem, what is the next step in the scientific method?
Answer: Conclusion
Explanation:
Scientific method can be defined as a detailed plan for conducting research in a particular scientific domain. This is used to give scientific explanation for natural phenomena. In scientific method a hypothesis is created, observation is made, experimentation is conducted and then finally a conclusion is made to address the hypothesis.
Therefore, after the research is completed the conclusion is made by analyzing all the facts related to the literature and results of the experiments.

Answer:interactive model of any normal project
Explanation:
Termites are insects that feed on wood, which contains cellulose. Scientists have observed that some termite species prefer wood that has been attacked by fungi. Construct an explanation for this observation.
Answer:
The termites and the fungi possess a symbiotic relationship because they rely on each other for survival. The fungi digest cellulose (that the termites can't digest) from the wood, and in turn, the termites provide the fungi an environment where they can grow and prosper. This explains why termites prefer a wood that was inhabited by fungi. This symbiotic relationship explains why termites prefer the wood that is inhabited by fungi.
Explanation:
(see above)
The best explanation for this observation is that Termites and the fungi engage in symbiotic relationship.
What is symbiotic relationship?Symbiotic relationship is a mutual relationship that occur between two organisms in which one organism benefits and the other organism neither benefit or loss.
Termites benefit by getting the nutrient they desired fro. the wood eaten by fungi.

Compare temperature and pressure conditions on the Earth's surface to those below the Earth's surface, and relate these conditions to the process of lithification.
Answer:
Explanation:
The temperature and pressure on the earth's surface is lower than that below the earth's surface. Generally, temperature and pressure increases as you move/dig down the earth's surface. This increase in temperature and pressure causes the earth's sediment (below the earth surface) to form a compact solid rock - this process is known as lithification.

If a DNA strand has 32 % guanine, what percent thymine does it contain?
A) 36%
B)18%
C)64%
D)32%
Answer:
B
Explanation:
Guanine and Cytosine pair together. So, if 32 percent is guanine, then 32 percent should also be cytosine. This is a total of 64 percent. The remaining 36 percent is split between thymine and adenine. So, Thymine will have half of 36 percent which is 18 percent.
This is for my biology class. It is for the osmosis potato lab (Google it if you don't know what it is) and I have to answer this question. I also have to include the words at the bottom. This is really confusing and I would be so happy if someone could please help me with this!
How can a scientist use this lab to determine the amount of solute in an Idaho potato?
Use the following vocabulary words in your final conclusion statement below:
Hypertonic, hypotonic, isotonic, dynamic equilibrium, solute, solvent, osmosis
Explanation:
A scientist can use this experiment to determine the amount of solute in any potato.
hypotonic solution is a relative term. it means when we compare two solutions one of them is considered to be a hypotonic if it's solute concentration is less than the other.
so if the solution has less solute concentration its hypotonic solution and if it has more amount of solute its hypotonic solution. if both solutions have same amount of solute then it will be considered as a isotonic solution. when we separate two solution hypertonic and hypotonic by a semipermeable membrane there occurs diffusion of water molecules from its higher concentration to its lower concentration that is from hypotonic solution to hypertonic solution.
this movement of water molecules is called osmosis. this occurs in order to obtain an dynamic equilibrium between the 2 solutions.
here we take start as solute and water as solvent.
thus when a scientist and potato in a hypotonic solution the water moves inside the potato cavity. the more the transfer of water molecules in the potato cavity the more in the sugar quantity present in the potato. this is because the water will try to obtain a dynamic equilibrium between the two solutions if the sugar quantity in the potato cavity is high then the water molecules needed to dilute that solution will also be high.
in in this way a scientist can determine the amount of salt present in the potato.
