1. Sepal: According to Vocabulary.com dictionary (n.d), sepal is one of the green parts that form the calyx of a flower.

Petal: According to Vocabulary.com dictionary (n.d), petal is part of the perianth that is usually brightly colored.

2. d. Of all the flowers measured in this sample 35% had a petal length of 3 or less (after rounding the petal lengths).

3. Petal length 4 and 5 occurs most frequently.

4. I got my answer, by determining the relative frequency to know the Petal length that has the largest value. This is as shown below:

Petal length 1 = .16

Petal length 2 = .33 - .16 =.17

Petal length 3 = .35 - .33 = .02

Petal length 4 = .58 - .35 = .23

Petal length 5 = .81 - .58 = .23

Petal length 6 = .97 - .81 = .16

Petal length 7 = 1.00 - .97 …show more content…
8. The frequency of the value 7 is 24

9. The sum of the first three frequencies (1, 3 and 4) in the frequency table for sepal width is 8

10. My answer to the previous question represent the numbers of flowers in the sample that has sepal width less than 2.4

11. The sum of the last three frequencies 1, 1 and 1 in the frequency table for sepal width is 3

12. The number of flowers in the sample that had sepal widths less than 4 is 146

13. The tallest bar in the plot represents the sepal width that occurred the largest number of times as 3.

14. > freq freq

setosa versicolor virginica

50 50 50

15. The two things about the table I created for the previous task are:

The frequency table for flower species contain words in the first row as opposed to numbers because the values of the input data are words which are coded as factor.

The meaning of the number in the second row of the table is the frequency of each of the flower. This represents 50 numbers of setosa, 50 numbers versicolor and 50 numbers virginica that makes up the

(The difference between each answer is - 1,2,3,4,5). I can predict last column is always going to be equal to the 2nd column. Another prediction I could explore how the last column has 2 even and 2 odd numbers. Row 6: 1+2+3+4+5+6 = 6x7 ÷ 2 = 21 (odd) Row 7: 1+2+3+4+5+6+7 = 7x8 ÷ 2 = 28 (even) Row 8: 1+2+3+4+5+6+7+8 = 8x9 ÷ 2 = 36 (even) This shows how the 2 odd & 2 even method continues throughout the sequence, this would be correct as the numbers from the last column (1,3,6,10,15,21,28,36…)...

...all of the alleles are dominant. Also, punnett squares 3 and 4 have a 100% probability because they both have at least two dominant alleles in the proper allele cross to result in a dominant allele in every box. All of these boxes have a dominant gene, and even though there are recessive genes present, they do not show because of the dominant allele. In punnett square 2, there is 75% chance for the dominant traits. This is because on box in the square is homozygous recessive, meaning there is no dominant gene present to show, and is the only form that the recessive gene will show in the phenotype. Lastly, punnett square 5, has a 50% probability of receiving the dominant trait. On the other hand, for the recessive phenotype, punnett square 6 has a 100% chance. This is because all alleles present are recessive, and to show a dominant trait, there needs to be a dominant allele present. Furthermore, square 7 has a 50% chance of showing the recessive allele. That is because a dominant ia also present, which is the more authoritative allele. Lastly, punnett square 8 shows a 25% probability for the recessive trait. This is because there are 2 dominant alleles which overpower the recessive alleles. These punnett squares support the original hypothesis because when 1 or more dominant alleles are present, the probability of the recessive trait as the phenotype is...

A light violet color (the clear) in on the bottom and does not mix with the blue solution. The blue, green, and orange seem to be the most distinct colors. The yellow seems to blend with the green and orange rather than having a separate color and the red is hard to see. The reason for the yellow mixing with the green is because some of the solution/fluid used with the green was still on the side of the test tube, so when the yellow dye was placed in, the solution/fluid meant to be green had yellow dye mixed in due to being stuck on the side of the test tube and the added yellow dye allowed the solution to slid down the test tube to join the rest of the green solution/fluid. Each color does not seem to mix with each other but a distinct area to be in...
