Recessive traits would never reappear if
A. zygotes were given opposite
alleles
B. zygotes did not separate during gamete formation
C. alleles did not separate during gamete formation
Recessive traits would never reappear if zygotes were given opposite alleles.
What do you mean by Zygote?Zygote may be defined as the outcome of the fusion of male and female gametes after successful fertilization.
Recessive traits are only expressed when both the copies of recessive genes are inherited from the parents.
Therefore, recessive traits would never reappear if zygotes were given opposite alleles.

Jake set up an experiment. He set two aquariums with five fish of the same type and size. Aquarium one was very small, only one cubic foot. Aquarium 2 was very large at 10 cubic feet. Each day the fish were fed the same amount of food and vitamins, at the end of 5 months Jake measured the fish by length. His results are shown in the bar graph above. What might be the question Jake is asking in his experiment?
A. What fish food cost the most?
B. What fish food makes fish grow faster?
C. Does aquarium size affect growth rate of fish?
D. What type of fish food do fish like the best?
Once identified the controlled, the independent, and the dependent variables, we can say the question is C. Does aquarium size affect the growth rate of fish?
What is the independent variable?
Refers to all the variables in an experiment that provoke a response in another variable.
An independent variable is the one that changes or is controlled and modified in the experiment to analyze how another variable responds to it.
It changes to analyze its effects on the dependent variable.
What is the dependent variable?Refers to the variable whose response depends on any change in the independent variable. Depending on how the independent variable is modified, the dependent variable changes.
What is the controlled variable?During an experiment, the controlled variables are kept constant. Unlike the independent variable, the controlled variables do not influence the results. These variables do not affect the response of the dependent variable.
In the exposed example,
the independent variable ⇒ Aquarium size ⇒ 1 cubic foot and 10 cubic feetthe controlled variable ⇒ food and vitaminsthe dependent variable ⇒ fishes growth.The question that Jake is asking in his experiment is Does aquarium size affect growth rate of fish? Option C.
Since he only needs to know how the size of the aquarium affects the animal's growth, he needs to keep constant other influencing variables such as food and vitamins. Otherwise, these other variables might also influence the results.

How do hypertonic, hypotonic, and isotonic solution affect the size of cells? Explain Osmosis and Diffusion.
When a cell is submerged in a hypertonic solution, water escapes and the cell shrinks. There is no net water flow in an isotonic environment, hence the cell size does not vary. Water will enter a cell when it is placed in a hypotonic environment, causing it to swell.
What are hypertonic solutions?A hypertonic solution is one where there is greater concentration of solute outside the cell than inside the cell. Since water follows the most solute, it leaves the cell. This causes animal and plant cell membranes to shrivel up. The plant cell walls remain intact but animal cells will suffer more.
What are hypotonic solutions?Hypotonic solutions is when water molecules move from a high water potential to a low one because of diffusion.
What are isotonic solutions?Isotonic solutions are those solutions that have the same osmotic pressure at a given temperature.
What are cells?A cell is the smallest basic unit of all living organisms. Cells provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized food function. Cells also contain the body's hereditary material (DNA) and can makes copies of themselves.
Part 2:Osmosis and DiffusionOsmosis is the movement of water across the cell membrane, where the water goes from a higher concentration to a lower concentration. It plays an important role in activation, growth, and differentiation of T and B lymphocytes, macrophages, NK cells and other non-hematopoietic cell types.
Cellular diffusion is the process that causes molecules to move in and out of a cell. Diffusion is important as it allows cells to get oxygen and nutrients for survival. In addition it plays a role in cell signaling which mediates organism life processes.
