Answers
Answer:

Explanation:
The second student set up solutions that were in equilibrium.
On which principle Dialysis is based?Dialysis is based on the principles of osmosis, meaning the net movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration. If the solute concentrations are the same on each side of the membrane, this spontaneous movement will not occur.
In passive diffusion, the small water molecules can move across the phospholipid bilayer seen in blue. This layer acts as a semi-permeable or selectively permeable membrane; its hydrophilic heads are attracted to water (seen facing outwards) while its water-repellent hydrophobic tails face towards each other- allowing molecules of water to diffuse across the membrane along the concentration gradient.
Therefore, the second student set up solutions that were in equilibrium.

How did you determine the types of cell division for both phases depicted in your model? Explain your answer.
Answers
Answer:
Cell division is a process that makes our skin, tissues, muscles, sex cells. It is the building block of our body.
Explanation:
When parents cells ahs been divided into two or more than two daughter cells then it is called division of cells. The division of cells occur as a larger cell. When we talk about eukaryotic cells, these cells divided into two distinct types of the cells, the vegetative cells.
The daughter cells are the identical to the parents cells genetically. There are two types of division such as mitosis and meiosis. When parents cells divides in daughter cells and daughter cells divided further, this process called the cells cycle. The mitosis cell division occur interphase. Meiosis cell division occur in two phase meiosis I and meiosis II.

Answers
Answer:
D / D / D / B / C
Explanation:
I just took the quick check myself, got all of them right :)
1 ) Top predators do not increase the number of prey, neither do they create imbalance or increase the food for other predator species. This is common knowledge, so ruling those out you are left with D. As they do in fact maintain the rest of the food chains populations.
2) A top predator in the ocean is a shark. Of course some might mistake a small whale to be a top predator, but sharks are actually known to hunt whales- the small ones anyway. A sea lion fish or a bird wouldn't exactly be a candidate for the top of the food chain either.
3) During seasonal flooding, to an area such as a river, water gets added to the existing pool, and many biotics and abiotics take this to their advantage. As a result- biodiversity actually increases during these times, but once season flooding is over it goes back to being the same.
4) The impact difference of seasonal flooding from damming a river is actually quite big. Seasonal flooding is.. well.. seasonal.. while damming for the most part is permanent, or will be there for much longer time span than season flooding is. Seasonal flooding increases biodiversity, but damming does not. This is becuase of the long term increase of water, the environment has to readapt, as plants that were once there drowned, and the known species most likely ran off to find better environment. Here it takes a while but eventually new abiotic and biotic species adapt and reclaim the dammed area of the environment.
5) Yes, a long term increase in the average temperature would disturb the ecosystem. Even if it's for a little bit, it's still something the environment wouldn't be used to, meaning the plants and animals there would have to learn to adapt for the time being- even if its temporary.
1: It maintains other populations
2: A shark
3: The biodiversity of the area increases
4: Seasonal flooding does not impact biodiversity for as long term as damming.
5: Yes, because such a change could have a large-scale impact on wildlife.

Which statement best describes how a catalyst can speed up a chemical reaction?
The catalyst decreases the activation energy needed.
The catalyst increases the concentration of products.
The catalyst binds to enzymes to release substrates.
The catalyst increases the concentration of reactants.
Answers
Explanation:
The catalyst decreases the activation energy needed.
Catalyst can speed up a chemical reaction by decreasing the activation energy needed. Thus option a is correct.
What is catalyst?Catalyst is defined as a material that allows a chemical process to happen under new circumstances or at a typically faster rate.
It can also be defined as an additive ingredient that can speed up a reaction without being consumed during the process.
There are basically four types of catalyst.
Homogenous catalystHeterogenous catalystHeterogenized homogenous catalystBiocatalystNickel, When making margarine out of palm oil, Ni is employed. In the Haber process, iron (Fe) is employed etc. are some of the example of catalyst.
Thus, catalyst can speed up a chemical reaction by decreasing the activation energy needed. Thus option a is correct.

Can hydrogen peroxide be broken down by catalysts other than those found in a living system? What is/are the control(s) and why are they needed?
Answers
Answer:
Can hydrogen peroxide be broken down by catalyst other than those found in a living system? Hydrogen peroxide can be broken down by manganese dioxide because it has catalytic properties. It is unstable which makes it very reactive. ... Sand however is not able to break it down
Explanation:
because it contains no catalytic properties
Manganese dioxide, which has catalytic properties, can degrade hydrogen peroxide. Because it is unstable, it is extremely reactive. It even degrades when exposed to light.
What is a catalyst?A catalyst is a substance that accelerates or reduces the temperature or pressure required to initiate a chemical reaction without being consumed in the process. Catalysis is the process of facilitating a reaction by adding a catalyst.
Hydrogen peroxide is one of the cleanest and most versatile chemicals available, decomposing to produce only oxygen and water (disproportionation).
The catalytic decomposition of hydrogen peroxide allows for the use of various catalysts to speed up the decomposition process.
Another consideration is that catalase is an enzyme that degrades at higher temperatures. The activation energy of the reaction changes as the catalyst decomposes.
As a result, the reaction will slow down. Manganese dioxide, on the other hand, does not decompose even at higher temperatures.
Thus, it can be concluded that hydrogen peroxide be broken down by catalysts other than those found in a living system.
