What is a Dihybrid cross?

A dihybrid cross may be characterized as a type of cross that significantly takes place between two individuals with two observed traits that are controlled by two distinct genes. It is a breeding experiment between two organisms that are identical hybrids for two traits.

According to the context of this question, the allele Y encodes for yellow color leaves, and y codes for green color leave. Yellow is dominant over the green. Similarly, S encodes for smooth leaves while s codes for rough seeds. Smooth is dominant over rough.

yyss is the only genotype that has a green and rough phenotype. While the possibilities that have yy in their genotypes must possess a green phenotype.

How many amino acids are there in A peptide, B peptide and C peptide in human insulin???​

Answers

Answer:

Insulin is composed of an A chain of 21 amino acids and a B chain of 30 amino acids. C-peptide is a peptide composed of 31 amino acids

Explanation:

Insulin is composed of an A chain of 21 amino acids and a B chain of 30 amino acids, the chains being held together by two disulfide bonds. A third disulfide bond is present within the A chain. Human insulin differs from porcine insulin by a single amino acid and from beef insulin by three amino acids.

Explanation:

Dashed circles around either an R or K indicate sites of peptidase cleavage that result in generation of the mature insulin that is comprised by two separate peptides: the A chain with 21 and the B chain with 30 amino acids. A third C peptide with 21 amino acids served as a linker between the A and B chains.

change.

Answers

Answer:

(b) The interquartile range of B is greater than the interquartile range of A.

(d) The median of A is the same as the median of B.

Explanation:

Given

[tex]A = \{1, 4, 2, 2, 3, 1, 1, 2, 1\}[/tex]

[tex]10th\ run = 9[/tex]

So:

[tex]B = \{1, 4, 2, 2, 3, 1, 1, 2, 1,9\}[/tex]

Required

Select all true statements

(a) & (d) Median Comparisons

[tex]A = \{1, 4, 2, 2, 3, 1, 1, 2, 1\}[/tex]                         [tex]B = \{1, 4, 2, 2, 3, 1, 1, 2, 1,9\}[/tex]

[tex]n = 9[/tex]                                                         [tex]n = 10[/tex]

Arrange the data:

[tex]A = \{1, 1, 1, 1, 2, 2, 2,3, 4\}[/tex]               [tex]B = \{1,1,1,1,2,2,2,3,4,9\}[/tex]

                               [tex]Median = \frac{n + 1}{2}th[/tex]

[tex]Median = \frac{9 + 1}{2}th[/tex]                            [tex]Median = \frac{10 + 1}{2}th[/tex]

[tex]Median = \frac{10}{2}th[/tex]                              [tex]Median = \frac{11}{2}th[/tex]

[tex]Median = 5th[/tex]                                 [tex]Median = 5.5}th[/tex] --- average of 5th and 6th

[tex]Median = 2[/tex]                                    [tex]Median = \frac{2+2}{2} = 2[/tex]

Option (d) is correct because both have a median of: 2

(b) & (c) Interquartile Range Comparisons

[tex]A = \{1, 1, 1, 1, 2, 2, 2,3, 4\}[/tex]               [tex]B = \{1,1,1,1,2,2,2,3,4,9\}[/tex]

[tex]n = 9[/tex]                                                         [tex]n = 10[/tex]

First, calculate the lower quartile (Q1)

[tex]Q_1 = \frac{n + 1}{4}th[/tex][Odd n]             [tex]Q_1 = \frac{n}{4}th[/tex] [Even n]

[tex]Q_1 = \frac{9 + 1}{4}th[/tex]                            [tex]Q_1 = \frac{10}{4}th[/tex]

[tex]Q_1 = \frac{10}{4}th[/tex]                              [tex]Q_1 = 2.5[/tex]

[tex]Q_1 = 2.5th[/tex]                              

This means that:

[tex]Q_1 = 2nd + 0.5(3rd - 2nd)[/tex]              [tex]Q_1 = 2nd + 0.5(3rd - 2nd)[/tex]

[tex]Q_1 = 1 + 0.5(1- 1)[/tex]                   [tex]Q_1 = 1+ 0.5(1 - 1)[/tex]                      

[tex]Q_1 = 1[/tex]                                       [tex]Q_1 = 1[/tex]

Next, calculate the upper quartile (Q3)

[tex]Q_3 = \frac{3}{4}(n + 1)th[/tex] [Odd n]             [tex]Q_3 = \frac{3}{4}(n)th[/tex] [Even n]

[tex]Q_3 = \frac{3}{4}(9 + 1)th[/tex]                            [tex]Q_3 = \frac{30}{4}th[/tex]

[tex]Q_3 = \frac{30}{4}th[/tex]                                     [tex]Q_3 = 7.5th[/tex]  

[tex]Q_3 = 7.5th[/tex]                                    

This means that:

[tex]Q_3 = 7th + 0.5(8th- 7th)[/tex]           [tex]Q_3 = 7th + 0.5(8th- 7th)[/tex]

[tex]Q_3 = 2 + 0.5(3- 2)[/tex]                       [tex]Q_3 = 2+ 0.5(4 - 2)[/tex]                      

[tex]Q_3 = 2.5[/tex]                                       [tex]Q_3 = 3[/tex]

The interquartile range is  [tex]IQR = Q_3 - Q_1[/tex]

So, we have:

[tex]IQR = 2.5 - 1[/tex]                  [tex]IQR = 3 - 1[/tex]

[tex]IQR = 1.5[/tex]                       [tex]IQR =2[/tex]

(b) is true because B has a greater IQR than A

(e) This is false because some spread measures (which include quartiles and the interquartile range) changed when the 10th data is included.

The upper quartile and the interquartile range of A and B are not equal

Which of the following is an example of a learned response? OA A child figures out how to ride a bicycle. O B. An adult salmon is able to return to the river where it hatched. OC. A plant turns to follow the sun during the day. OD. A man blinks when an object is tossed toward his face.​

Answers

Answer:

Explanation:

I would say A. Learning to ride a bicycle is a process of getting on and falling off. You have no idea how to do it properly without practice. That's learned.

But look out for D. I'm not sure that that isn't instinctive. Somewhere along the line I think even a baby knows not to let his/her eyes be touched. Is it learned? It's close but A is a much better answer.

The salmon is instinctive. The plant doesn't learn to turn towards the sun. It does so because more food is produced.

Yes, it's A.

A is the only option that is not instinctual. Riding a bicycle is something that has to be taught (and even if you weren't taught to ride a bike, you had to figure it out by trial and error.)

The other options are instinctual and reflexive responses. The salmon returning to the river is a behavior that is pretty much hard-wired into the salmon's brain. The plant turns to follow the sun because it is a source of light and energy.

The other user expressed uncertainty as to option D, but in fact, option D is very much a reflexive, instinctual response as well. To flinch or blink when something abruptly moves towards you is not a choice or something you have to be taught — it's a reflex, something you can't control.

Write a scientific explanation to explain how natural selection and adaptation increase or decreases the chances of survival for the mice if they entered one another’s environment.

Answers

Answer:

Natural selection is a factor of biological evolution, by means of which individuals who possess a certain characteristic tend to prevail over those who lack such characteristic. Thus, by reproducing, individuals with favorable characteristics end up imposing their own set of characteristics, taking control of the environment in which they develop and relegating other individuals or condemning them to their extinction or displacement.

Thus, in the case, if some mice entered the environment of others, most likely they would not be able to adapt to the conditions to which the original group of that environment had previously adapted. In this way, natural selection itself would make the new mice end up disappearing from it, in favor of the mice that already lived there and that, therefore, had adapted their characteristics to those of the environment.

Answer:

a) Side chains that can form hydrogen bonds are located on the outside of a protein, where they can stabilize tertiary structure by forming hydrogen bonds with water.

Explanation:

explain why it is an advantage for plants to store carbohydrates as starch rather than as sugars​

Answers

Answer:

More energy are packed into less space by starch molecules far more than glucose or sucrose yet they are able to release this energy easily, hence maximizing both storage and mobilization.

Explanation:

When plants have a period of dormancy to survive, they store their food as starch. They store enough of this energy so as to be able to restart with and to be able to maintain metabolism for the entire period of dormancy.

In addition, we know that starch is not water soluble, hence, lacks the ability to pull water into storage cells or cause irregularity in water balance. More energy are packed into less space by starch molecules far more than glucose or sucrose yet they are able to release this energy easily, hence maximizing both storage and mobilization.

Glucose is not directly transported by plants to storage. Rather, in a plant stem, the form of carbohydrate being transported is sucrose and this is because it is a non-reducing and does not react with oxygen during transport in the stem to specialized storage plastids.

It is advantageous for plants to store carbohydrates as starch rather than as sugars because:

sugars such as sucrose, fructose, and glucose are soluble and cannot be stored in the body of plant.as such, plants have to find a way to store their food reservesone way to store the food would be to store them in less soluble form that cannot be washed away easily and can also be converted to usable forms when needed.Hence, starch provides for that option. Cellulose could also have been a choice, but its structure makes it such that it becomes a permanent part of the plant and cannot be converted to usable food anymore.

Hence, it is advantageous to store carbohydrates as starch by plant rather than sugars because starch cannot be washed away easily and can also be converted to usable foods when needed.

In the F2, the following results were obtained: 672 long-winged flies 218 dumpy-winged flies The student tested the hypothesis that the dumpy wing is inherited as a recessive trait by performing chi-square analysis of the F2 data.

Determine:
a. Chi-Square Value.
b. Degrees of freedom.
c. Reject or fail to reject the hypothesis.

Answers

Answer:

a. Chi-Square Value = 0.12

b. Degrees of freedom = 1

c. Reject or fail to reject the hypothesis = fail to reject the hypothesis

Explanation:

Available data:

Cross: long wings to flies with mutant, dumpy wingsF1) 100% long-winged fliesF2)  672 long-winged flies 218 dumpy-winged flies Hypothesis: the dumpy wing is inherited as a recessive trait

Let us name the allele for Long L and the allele for dumpy l

The number of observed individuals:

Total number: 890 flies (672 + 218) Long-winged = 672 Dump-winged = 218

In the F2 generation, if l was a recessive allele and L a dominant allele, exhibiting complete dominance, we would expect a 3:1 phenotypic ratio.

Cross:          Ll   x   Ll

Gametes)   L   l    L  l

Punnett square)   L     l

                     L    LL    Ll

                      l     lL     ll

F2) 3/4 LL + Ll long-winged individuals

      1/4 ll dump-winged individuals

From this ratio and the total number of individuals in the F2 generation, we can get the expected number of individuals:

4 possible genotypes ------- 890 individuals

3 LL + Ll genotype ------------X = 667.5 long-winged individuals

1 ll genotype ---------------------X = 222.5 dump-winged individuals

 

Chi square = ∑ (O-E)²/E

LL + Ll = (O-E)² /E

LL+ Ll = (672 - 667.5) ² / 667.5

LL + Ll = 0.03

ll= (O-E)²/E        

ll= (218 - 222.5)² / 222.5

ll= 0.09  

Chi square= ∑ ((O-E)²/E) = 0.03 + 0.09 = 0.12 Freedom Degrees = genotypes - alleles = 3 - 2 = 1 Significance level = 0.05     Table value/Critical value = 3.84

0.12 < 3.84 meaning that there is enough evidence to reject the null hypothesis.

Fail to reject the hypothesis.  The genotypes in the population might be in equilibrium H-W. L is the dominant allele, and l is the recessive allele. The dumpy wing is inherited as a recessive trait.
