mendel’s law of segregation states that the two alleles for each gene separate during gamete formation. during which stage of meiosis do the alleles separate?
Answers
The stage of meiosis at which the alleles separate is anaphase. The correct option is B.
What is meiosis?Meiosis is a type of cell division of germ cells that produces gametes such as sperm or egg cells in reproducing organisms through gametes.
It entails two rounds of division, resulting in four cells with only one copy of each chromosome.
Meiosis 1 separates a pair of homologous chromosomes and converts a diploid cell to a haploid cell. It is divided into four stages: prophase, metaphase, anaphase, and telophase.
The homologues are pulled apart and moved to opposite ends of the cell during anaphase I.
The sister chromatids of each chromosome, on the other hand, remain attached to one another and do not separate. Finally, in telophase I, the chromosomes arrive at the cell's opposite poles.
Thus, the correct option is B.

a red onion cell has undergone a change, as represented in the diagram below. This change is most likely due to the cell being placed in...
Answers
We can see that the cell is shrivelled meaning osmosis has taken place. So it must be salt water
A red onion cell placed in a saline solution will lose water when water moves from the cell to the surrounding hypertonic medium via osmosis, causing the cell to shrivel up.
What is osmosis?The passage of solvent molecules from a lower concentration solution to a higher concentration solution across a semipermeable membrane. It is a passive process that occurs without the use of any energy.
Solvent molecule transfer proceeds from low to high concentration regions until the concentrations on both sides of the membrane are equal.
What are the types of osmosis?An isotonic solution contains the same solute concentration both within and outside the cell.A hypertonic solution has a larger solute concentration outside than inside the cell.A hypotonic solution contains a larger concentration of solutes inside the cell than outside.Thus, we can conclude that when a red onion cell is placed in salt water.
As we can see in the diagram the onion cell shrink which means it is placed in salt water which is a hypertonic solution.
So, option (3) salt water is correct.

What is the relationship between the light-dependent and light-independent reactions of photosynthesis
Answers
Answer:
In the light-dependent reactions, energy from sunlight is absorbed by chlorophyll and that energy is converted into stored chemical energy. In the light-independent reactions, the chemical energy harvested during the light-dependent reactions drives the assembly of sugar molecules from carbon dioxide.

A sieve is a container with a mesh or perforated bottom. What is the most common use for a sieve? A. to steam cook chemicals in the lab B. to store liquid substances C. to allow gases to escape from reactions D. to filter larger particles out of a mixture
Answers
Answer: D
Explanation: Sieves are used to separate the solid smaller particles from a mixture. They are usually made of metal or fine plastic mesh, with openings between the wires that are sized according to the sizes of the desired particles in the mixture. Dried foods such as beans and rice are separated by using screens with openings of different sizes, small for whole grains, larger for cracked grains. Other kinds of products which require separation may be filtered through sieves, including sugar mixtures before they are packed or bottled.
