What is the main reason that it takes 2 to 3 minutes for the reaction to occur between sucrose and sulfuric acid in the dehydration of sucrose? the activation energy needs to be overcome in the reaction. the activation energy must be removed from the intermediates. the sulfuric acid has to be consumed before the reaction takes place. the sucrose molecules must rearrange to become the catalyst.
The main reason for this activity is the activation energy needs to be overcome in the reaction.
What do you mean by Dehydration?Dehydration may be defined as a process where there is a removal or loss of water takes place from something.
When the reaction between sucrose and and sulfuric acid is carried, it may leads to dehydration of sucrose. As a result of this, activation energy requires to come up in the reaction.
Therefore, the main reason for this activity is the activation energy needs to be overcome in the reaction.

How does the structure of the water molecule lead to its
ability to dissolve polar compounds?
Answer:
It is polar, allowing for the formation of hydrogen bonds, which allow ions and other polar molecules to dissolve in water. Therefore, water is an excellent solvent. The hydrogen bonds between water molecules give water the ability to hold heat better than many other substances.

Meiosis Questions:
1. How many chromatids are present in one homologous pair of chromosomes?
2. What is meant by “crossing-over” in meiosis, and how did your model depict this?
3. What effect does crossing-over during meiosis have on the genetic makeup of daughter cells?
4. Why must the number of chromosomes in reproductive cells (gametes) be different than the number of chromosomes in the rest of an organism’s cells (somatic cells)?
Explanation:
Two sister ChromatidsCrossing over is the exchange of genetic material between two homologous chromosomes to give rise to recombinant chromosomesallows the daughter cells of meiosis to be genetically unique from one another. because the DNA of the parent cell is shuffled before the cell divides.The plant cellwall is made up of carbohydrate calked chitin.true /false

How do the kidneys compensate for acid-base imbalances?.
Kidneys compensate for acid-base imbalances by : Reabsorbing HCO₃ from urine back to the blood and also secreting H⁺ back to the urine.
Acid-base ImbalanceWhen the amount of acid or base produced in the human body is greater than or less than the required amount of acid or base, and the rate of excretion by the kidneys is above or below normal, the body will experience an Acid-base imbalance situation.
To correct acid-base imbalance in the body the kidney will reabsorb HCO₃ form the urine and while secreting Hydrogen ions back to the urine.
Hence we can conclude that Kidneys compensate for acid-base imbalances by : Reabsorbing HCO₃ from urine back to the blood and also secreting H⁺ back to the urine.
