What are the differences of cytokinesis in animal and plant cells?
Karyokinesis, or the partition of a nucleus into two daughter nuclei, comes before cytokinesis. All eukaryotes go through cytokinesis in a manner that is remarkably similar. However, it frequently varies between cells with a cell wall, like plant cells, and cells without a cell wall, like animal cells.
Answer: The main difference is the formation of a new cell wall surrounding the daughter cells.
Explanation:
In a plant cell, a cell plate is formed between the two daughter cells.
In animal cells, a cleavage furrow is formed between the two daughter cells.

Below are the reduction half reactions for chemolithoautotrophic denitrification, where hydrogen is a source of electrons and energy and nitrate is the terminal electron acceptor.
NO3- + 10e- -> N2 (E0 = +0.74 V)
H+ + 2e- -> H2 (E0 = -0.42 V)
If you balance and combine the reactions so that 90 moles of H2 gas are oxidized to H+, how many moles of N2 gas will be produced?
39462 KJ of Gibbs free energy will produce. Number of moles of nitrogen = 90 moles, E0 = 0.74 + ( - 0.42) = 0.74 - 0.42 = 0.32
What is a Balanced chemical equation?A balanced chemical equation has the same number of reactants and products. We can balance a chemical equation by adding a number to adding the same number of molecules on both sides.
In this equation,
10NO3 + 10 e - -> 5N2
4H + 2 e - -> 2H2
In this equation, 5 moles of N2 and 2 moles of Hydrogen are produced.
5 * 0.74 = 3.7 V
2 * ( -0.42) = - 0.84 V
ΔG = -nFΔE,
where F = 96.48 kJ (mol e-)
= 90 * 96.48 * (3.7 + 0.84)
= 90* 96.48* 4.54
= 39462 KJ
Therefore, 39462 KJ of Gibbs free energy will produce. Number of moles of nitrogen = 90 moles, E0 = 0.74 + ( - 0.42) = 0.74 - 0.42 = 0.32.

Compare the rate of pepsin-catalyzed reaction to ph 3 with the rate of the trypsin-catalyzed reaction at ph 3
When pepsin is in a pH 3 medium it will be active but not in its most active form and trypsin in a pH 3 medium will be inactive since it is at a more acidic pH than it acts.
What is the optimal pH at which these enzymes act?Pepsin will be at a high speed, but not the most optimal since the pH at which it works best is between 1.5-2.5 and at a higher pH it begins to deactivate. While trypsin needs a pH greater than 7.7 to start reacting since this is its optimal pH, then being in a medium with pH 3 it will not reach alkalinity to be able to react
Therefore, we can confirm that when pepsin is in a pH 3 medium it will be active but not in its most active form and trypsin in a pH 3 medium will be inactive since it is at a more acidic pH than it acts.

why do the cytoplasmic strands pass nearer to the cell wall than to the sap vacuole
Transport from vacuoles happen through osmosis and diffusion, they lack plasmodesmata required for the passage of cytoplasmic strands.
All cells with a nucleus have cytoplasmic strands, which are spindle-shaped strands. Their major function is to keep the nucleus in place so that it doesn't move from its original position in the cytoplasm. They are additionally known as plamodesmata.When water enters the cell's vacuole but not the nucleus, plant cells experience turgor pressure.Plant cells have channels called plasmodesmata that cross their cell walls to allow for movement and communication. Strands of cytoplasm from a nearby cell communicate through these open channels called plasmodesmata, which are found in plant cell walls.As a result, unlike sap vacuoles which lack communicating channels, cell walls feature plasmodesmata that let cytoplasmic strands move from one cell to another.

Explanation:
The water droplets formed on the surface of the lemonade because Regina said, "The droplets on the outside of the pitcher are water." They came from the air outside the pitcher, which is option B.
What are the different forms of water?Water is present in liquid form, but as the temperature rises, it converts into a gas, which is water vapor. This vapor is present in the atmosphere as a gas, but when it comes into contact with the colder surface, which is the outer surface of the lemonade glass, due to the condensation, the vapor converts into the liquid. When the temperature drops further, the water condenses into a solid, which means ice.
Hence, water droplets formed on the surface of the lemonade because Regina said, "The droplets on the outside of the pitcher are water." They came from the air outside the pitcher, which is option B.

If the temperature range was between 10 degrees Celsius and 100 degrees Celsius instead, the amount of liquid water would decrease, and the amount of solid water would increase. Option A.
Boiling and freezing points of waterWater molecules freeze at temperatures below zero degrees Celsius and boil from a temperature of 100 degrees Celsius and above.
This means that water will be liquid at temperatures between 0 and 100 degrees Celsius.
Now, if the lower boundary is increased - the freezing temperature is increased to 10 degrees Celsius. It means any water below 10 degrees Celsius will be frozen while the temperature range for liquid water has been narrowed.
In other words, the amount of liquid water would decrease, while the amount of frozen or solid water will increase.
