Answer:
Five (5)
Explanation:
A <u>total of five (5) paramecia </u>can be accommodated within the FOV.
The field of view of a microscope represents the area of the visible region under the ocular/eyepiece at a specific magnification. In other words, the diameter of the circular area visible through the ocular of the microscope at a specific magnification represents the field of view.
<em>If a paramecium was found to occupy 20% of the total field of view of a microscope at X40 magnification, then the total number of paramecia that can be accommodated within the field would be:</em>
100/20 = 5 paramecia
Given the nature of a punnet square, we can conclude that the ratio in question refers to the combination of genotypes present in the square.
A punnet square is a diagram used to attempt to predict the <u>genetic composition </u>for the <u>offspring</u> of certain parents, that is the genotype for this specific cross. This is done by creating a square in the form of a grid and placing the genotypes of the parents on the outside of this then crossing them along the inside.
This diagram provides us with the probability of each genotype outcome. This is known as the phenotype ratio. The phenotypic ratio is the amount of times a specific outcome, such as a certain pair of alleles appears in the predicted genotypes of any of the <u>offspring pertaining </u>to this <u>cross</u>.

because antibodies can potentially be generated against millions of unique epitopes, the size of an organisim's genome would need to increase exponentially in order to every possible antigen- binding side.
An oxygen atom alone will have 6 valence electrons (outermost electrons). A hydrogen atom each has 1 electron in its outermost shell to share with the oxygen. For oxygen to have a filled outer shell, it will take one electron from each of the two hydrogens into it's outer shell. This means, the number of electrons in its valence shell will be the original amount of electrons oxygen has by itself plus 1 electron from each hydrogen atom. This will form a water molecule
