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.

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.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.

Describe the theory of evolution in your own words. How does this theory relate to the principle of natural selection?
Answer:
The theory of natural selection was explored by 19th-century naturalist Charles Darwin. Natural selection explains how genetic traits of a species may change over time. This may lead to speciation, the formation of a distinct new species.
Explanation:
Original Question:
Describe the theory of evolution in your own words. How does this theory relate to the principle of natural selection?
Answer and Explanation:
Evolution means the adaption of animals, plants, species, etc. This study ties in with the theory of humans being descended from other animals; specifically chimpanzees. Over the course of time, Animals are believed to adapt to the environment they live in. One common example would be giraffes. In the past, they used to have shorter necks that couldn’t the leaves in a tree. Throughout the years, many breeds tended to have offsprings that had long necks. That is why giraffes have longer necks now.

Tall oak trees are better able to compete for sunlight in crowded forests. short oak trees are at a
disadvantage. what type of selection appears to have made oak trees grow tall?
a. stabilizing selection
b. directional selection
c. disruptive selection
The type of selection that makes tall oka trees a better competitor for sunlight over short ones would be directional selection.
What is directional selection?It is a kind of natural selection in which individuals with traits at one extreme end of the population are better adapted to the environment.
In this case, tall and short oak trees are at the two extreme ends of the population mean with tall oak trees being able to better competitors for sunlight than the short ones.
The selection is, thus, directional, towards the tall trees rather than the average or the short ones.
