what are the differences between recombination after conjugation in prokaryotes and recombination during meiosis in eukaryotes
Recombination is a process of genetic exchange that occurs during reproduction, where DNA sequences from two different sources are combined to create a new genetic sequence.
There are two main types of recombination: homologous recombination and non-homologous recombination.
Recombination after conjugation in prokaryotes:
During conjugation in prokaryotes, a donor bacterium transfers a plasmid or a part of its chromosome to a recipient bacterium through a physical connection called a pilus. This process involves the transfer of genetic material from one bacterium to another, which can result in recombination. Recombination during conjugation in prokaryotes is usually homologous, meaning that it occurs between two similar sequences of DNA. This process can result in the transfer of antibiotic resistance genes or other advantageous traits between bacteria.
Recombination during meiosis in eukaryotes:
Meiosis is a process of cell division that produces haploid gametes (sperm or eggs) from diploid cells. During meiosis, homologous chromosomes exchange genetic material through a process called crossing over. This results in the creation of new genetic combinations, which are then separated into different gametes during meiosis. The process of recombination during meiosis in eukaryotes is also homologous, but it is more complex than recombination after conjugation in prokaryotes. The exchange of genetic material during meiosis can result in the production of offspring with different traits and can contribute to the genetic diversity of a population.

What does hypotonic mean in biology?
In biology, hypotonic refers to a solution that has a lower concentration of solutes compared to another solution, which can cause water to move into the cell and potentially lead to cell lysis or bursting.
When a cell is placed in a hypotonic solution, water will move from the solution into the cell in an attempt to balance out the concentration of solutes. This can cause the cell to swell and potentially burst if the influx of water becomes too great. Hypotonic solutions are commonly used in laboratory settings to lyse or break open cells to extract their contents, but in living organisms, cells are typically able to regulate their internal solute concentrations to avoid excessive swelling and bursting. Hypotonic solutions can also have physiological effects on the body, such as causing red blood cells to swell in certain medical conditions.

ii. The speed of sound in air is 340 m/s. Use your value of time from 3. b. i. to calculate the length of the school field.
Answer:
Explanation:
In part 3.b.i, we calculated the time it took for the sound to travel from the source to the observer:
t = 0.0466 seconds
We can use this time and the speed of sound in air to calculate the distance traveled by the sound wave:
d = v * t
where v is the speed of sound in air and t is the time.
d = 340 m/s * 0.0466 s
d = 15.844 m
This is the round-trip distance traveled by the sound wave, which includes the distance from the source to the building and back. To find the one-way distance from the observer to the building, we need to divide this distance by 2:
d/2 = 15.844 m / 2
d/2 = 7.922 m
Therefore, the length of the school field, which is the distance between the observer and the building, is approximately 7.922 meters.
Answer :
7.922 meters
