Answer:
The classic tool to predict the patterns of heredity is using a <u>Punnett Square</u>.
Explanation:
In genetics, a trait can be considered dominant or recessive. Since the important discoveries of Gregor Mendel, scientists use a <u>capital letter (D) to indicate a trait is dominant, and a lowcase letter (d) to show a trait is recessive. </u>
Assuming that a scientist knows the genotype for the desired trait they want to predict on the offpsring, a Punnett Square is<u> a reliable tool and a graphic representation that permits them to visualize the potential features of the offspring by showing how the alleles may be exhibited and passed on the offspring and will determine the possible combination of genotypes.</u>
<em>How does it work?</em>
For example, as we can observe in the image below, both parents are homozygous for a trait <em>PP=Purple; pp=white</em>. P is dominant and p is recessive (the color purple will be dominant, and the white will be recessive). So, we put one parent's genotype in the top row (PP) and the other parent's genotype in the left column (pp) and combine one of each letters on the squares, <em>i.e</em>. one of each parent's alleles. Then, we can observe in the results that 3 of the offspring will exhibit the purple color (PP, Pp, Pp) and only one will exhibit the white recessive color (pp); or more properly known as a genotypic ratio of 3:1.
Answer:
It is neither accurate nor precise.
Explanation:
<em>The data set is neither accurate nor precise.</em>
Accuracy is defined as the closeness of a measurement to the true value.
Now let us look at the average of the data set:
30 + 17 + 27 + 21 + 32 = 127/5 = 25.4
<u>The average of the data set is 25.4, whereas the correct value provided is 25. The difference between the average of the data set and the correct value is 0.4 which is beyond the margin of error allowed in measurement. Hence, the measured data is not accurate.</u>
Also, precision is defined as the closeness of repeated measurement to one another.
<u>From the data set, the individual values are not close to one another in any form and the difference between them are more than the margin of error allowed in measurements. Hence, the data is far from being precise.</u>
The correct answer is C. 36
Explanation:
In genetics, a nucleotide refers to the basic units that form genetical material. On the other hand, a codon refers to a sequence of three nucleotides in the mRNA or messenger RNA which are a set of molecules that take genetical information from ADN to the ribosome of the cell. This implies in the case of a 12 mRNA codons there are 36 nucleotides as each of the codons contains three nucleotides which means by multiplying the number of codons by three (number of nucleotides) it is possible to know the total number of nucleotides in an RNA sequence or in this case 12 (codons) x 3 (nucleotides) = 36 nucleotides.
Answer:
e. Quantity of oxygen consumed when the food is burned
Explanation:
The quantity of oxygen that's used up is known as an indirect measure for amount of energy that's released from the food you burn and Bomb calorimeters may be used to estimate the amount of energy in food.
