The answer is 4 new (daughter) cells.
In meiosis, it produces 4 daughter cells which are genetically different from both the parent and the other daughter cells.
the parent cell first duplicates its chromosomes, just like mitosis (the kind of division that leads to 2 genetically identical daughter cells) . Then it divides, leading to 2 genetically identical daughter cells. But this does not end here. The 2 daughter cells further divides into total of 4 daughter cells, but without duplicating the DNA. That's why, the daughter cells has different DNA materials.
These daughter cells has half of the parents chromosomes, and we call them haploid.
Haploid cells are usually common in gametes. When an organism reproduces sexually, 2 gametes fuse together and leads to diversity.
- Place the scanning objective above the specimen by clicking it into place.
- To move the stage all the way up, use the coarse adjustment knob.
- Use the fine adjustment knob to focus the specimen.
- To improve contrast, adjust the iris diaphragm and/or the light control knob.
- Move a given structure to the center of your field of view using the mechanical stage controls.
<h3>What is epithelial cells ?</h3>
Epithelial cells are the cells that cover the inside and outside of your body's surfaces. They can be located on your skin, blood vessels, and organs such as your urinary tract.
<h3>What does it mean if my epithelial cells are high?</h3>
If urinalysis findings show a moderate or high number of epithelial cells, it may indicate the following medical conditions: Kidney illness Liver disease Yeast infections Urinary tract infections Certain kinds of cancer.

Answer:
Taking into account the principle of osmosis, the question that best addresses experimental design is <em>How does the effect of environmental sucrose concentrations impact the movement of water across a membrane?</em>
Explanation:
The experimental design of the student, made with dialysis bags and sucrose at different concentrations should recreate the principle of osmosis, of importance in living beings for organic homeostasis.
Osmosis consists of the movement of water - through a semi-permeable membrane - from a less concentrated solution to a higher concentration solution, following a gradient, to achieve balance.
The student will observe in his experiment that water moves from the solution with less sucrose concentration to the higher concentration of sugar. Beakers with the highest concentration of sucrose will have the highest weight, due to the increase in liquid volume.
How does the effect of environmental sucrose concentrations impact the movement of water across a membrane?
The experiment shows that:
- The water from the beaker with less sucrose concentration moved -through the dialysis tubes and the membrane- to the beaker containing the most concentrated sucrose.
- Different sucrose concentrations will attract different amounts of water, which influences the final weight of each container.
With this experiment the principle of osmosis is confirmed, where the concentration of a solute determines the amount of water that passes through a semipermeable membrane -following a concentration gradient- until equilibrium is reached.
