Mendel's law of segregation states that gametes only carry one allele for each gene. How much genetic information does a gamete carry, compared to a body cell?.

Answers

Gametes carry half the genetic information of an individual, one ploidy of each type, and are created through meiosis, in which a germ cell undergoes two fissions, resulting in the production of four gametes.

About Mendel's Law I

Mendel's Law I has another name, namely the Law of Segregation. In the Law of Segregation it states that "In the formation of gametes (sex cells) in the two genes which are partners, will be separated in two daughter cells". Mendel's Law I or the Law of Segregation applies to monohybrid crosses, aka crosses with one different trait.

Mendel's First Law also states that two alleles (gene variants) that regulate certain traits will separate in two different gametes (sex cells). Mendel's Law I includes several things, namely:

Alleles (gene variations) for inherited trait variations. For example: the colors of two different flowers, called alleles, will occupy the locus that corresponds to the homologous pair. Two alleles for a character will separate when gametes (sex cells) are produced. Example: the result of a cross containing one allele of the parent flower color (purple or white) Each character in each organism will inherit two alleles, each of which comes from the parent. Example: the result of a cross that is likely to produce 1 white allele and 1 purple allele. If there are two different alleles, one of them will be dominant, while the other will be recessive. Example: there is a marriage of purple flowers with white flowers, it will produce purple offspring.

Use method of reduction of order to find a second solution y2(x) of the homogeneuos equation and a particular solution of the given nonhomogeneous equation:
y" - 4y = 2; y1 = e^-2x
Please use equation and not substitution

Answers

The homogeneous equation and a particular solution of the given nonhomogeneous equation is [tex]& y=c_1 e^{-2 x}+c_2 e^{2 x}-\frac{1}{2}[/tex].

The given nonhomogeneous equation is y" - 4y = 2

We are given [tex]$y_1=e^{-2 x}$[/tex]

Let [tex]$y_2=u y_1$[/tex]

A linear differential equation is homogeneous if it is a homogeneous linear equation in the unknown function and its derivatives.

Non-homogeneous differential equations are simply differential equations that do not satisfy the conditions for homogeneous equations. In the past, we’ve learned that homogeneous equations are equations that have zero on the right-hand side of the equation.

The two most common methods when finding the particular solution of a non-homogeneous differential equation are:

The method of undetermined coefficients. The method of variation of parameters.

[tex]$$\begin{aligned}& y_2=u e^{-2 x} \\& y_2^{\prime}=u^{\prime} e^{-2 x}-2 u e^{-2 x} \\& y_2^{\prime \prime}=u^{\prime \prime} e^{-2 x}-2 u^{\prime} e^{-2 x}-2 u^{\prime} e^{-2 x}+4 u e^{-2 x} \\& y_2^{\prime \prime}=u^{\prime \prime} e^{-2 x}-4 u^{\prime} e^{-2 x}+4 u e^{-2 x}\end{aligned}$$[/tex]

Substitute in [tex]$y^{\prime \prime}-4 y=0$[/tex], we get

[tex]$$\begin{aligned}& u^{\prime \prime} e^{-2 x}-4 u^{\prime} e^{-2 x}+4 u e^{-2 x}-4 u e^{-2 x}=0 \\& u^{\prime \prime} e^{-2 x}-4 u^{\prime} e^{-2 x}=0 \\& e^{-2 x}\left(u^{\prime \prime}-4 u^{\prime}\right)=0 \\& u^{\prime \prime}-4 u^{\prime}=0 \\& u^{\prime \prime}=4 u^{\prime}\end{aligned}$$[/tex]

Substitute [tex]$$u^{\prime}=v$ and $u^{\prime \prime}=v^{\prime}$[/tex], we get

[tex]$$\begin{aligned}& v^{\prime}=4 v \\& \frac{d v}{d x}=4 v \\& \frac{1}{v} d v=4 d x\end{aligned}$$[/tex]

Integrate both sides, we get

[tex]$u=\frac{1}{4} C_1 e^{4 x}+C_2$$[/tex]

put in [tex]$y_2=u y_1$[/tex]

[tex]$$y_2=\left(\frac{1}{4} C_1 e^{4 x}+C_2\right) e^{-2 x}$$[/tex]

Choose [tex]$$C_1=4$ and $C_2=0$[/tex], we get

[tex]$$y_2=e^{2 x}$$[/tex]

[tex]$$\begin{aligned}& y_c=c_1 y_1+c_2 y_2 \\& y_c=c_1 e^{-2 x}+c_2 e^{2 x}\end{aligned}$$[/tex]

Particular Solution

[tex]$$\begin{aligned}& y_y=A \\& y_y{ }^{\prime}=0 \\& y_y{ }^{\prime \prime}=0\end{aligned}$$[/tex]

Substitute in [tex]$y^{\prime \prime}-4 y=2$[/tex], we get

[tex]$$\begin{aligned}& 0-4 A=2 \\& -4 A=2 \\& A=-\frac{1}{2} \\& \therefore y_y=-\frac{1}{2}\end{aligned}$$[/tex]

General Solution

[tex]$$\begin{aligned}& y=y_6+y_y \\& y=c_1 e^{-2 x}+c_2 e^{2 x}-\frac{1}{2}\end{aligned}$$[/tex]

Therefore, the second equation is [tex]& y_{2} =c_1 e^{-2 x}+c_2 e^{2 x}-\frac{1}{2}[/tex].

Answer:

"A) 12n + 14m + 4" would be the standard form.

Step-by-step explanation:

the expression written correctly in standard form would be "A) 12n + 14m + 4"

10m + 3(n + 8) + 4(m - 5) + 9n you need to first clear the parenthesis by applying distributive property:

10m + 3(n + 8) + 4(m - 5) + 9n = 10m + 3n + 24 + 4m - 20 + 9n

What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Food Lion sells 5- 15 ounce cans of beans for $4.00.

Aldi sells 4- 15 ounce cans for $4.00.

So, Food lion sell one can

= 4/5

= $0.8

and, Aldi sells one can at

One angle of a triangle measures 70°. The other two angles are in a ratio of 4:7. What are the measures of those two angles?

Answers

The measure of the other two angles are 88 degrees and 22 degrees.

Let's call the two unknown angles x and y. Since the sum of all angles in a triangle is 180 degrees, we have:

x + y + 70 = 180

We also know that the ratio of the two angles is 4:7. We can set up a proportion to express this relationship:

x/y = 4/7

We can cross-multiply to get:

7x = 4y

We can substitute this equation into the first equation to eliminate one of the variables.

7x + y + 70 = 180

Now we have:

7x + y = 110

We can use the second equation to eliminate x:

7(4y/7) + y = 110

4y + y = 110

5y = 110

y = 22

Now that we know one of the angles is 22 we can substitute it back in the first equation

x+22+70 = 180

x = 88

Therefore, the measures of the other two angles are 88 and 22 degrees

In a dividing competition, scores range from 0 to 10. When three judges, the number of points awarded is calculated by multiplying the sum of the scores by the degree of difficulty. Your opponent earns 40.8 points on a dive. You perform a dive with a degree of difficulty of 2.4. Two of your scores are shown. What scores from the third judge will give you more points than your opponent?

Answers

Answer:

1.5 or greater than 1.5

Step-by-step explanation:

First, we need to determine the total score of your opponent's dive:

40.8 points / 2.4 (degree of difficulty) = 17 (total score)

Now, we know that your total score needs to be greater than 17, and the scores awarded by the three judges are added together.

To calculate the scores from the third judge, we can use the following equation:

(Total score) - (score from judge 1) - (score from judge 2) = (score from judge 3)

Let's assume that you received scores of 8 and 7.5 from the first two judges.

We can plug in the values into the equation:

(Total score) - (8) - (7.5) = (score from judge 3)

We know that your total score needs to be greater than 17, so we have to find the score from the third judge, that when added to the scores 8 and 7.5, gives a total score greater than 17

17 - 8 - 7.5 = 1.5

The score from the third judge should be 1.5 or greater than 1.5 in order to give you more points than your opponent.

As of February 1, Job A21, the only job in process, had incurred direct material costs of $30,000 and direct labor costs of $50,000.2. Jobs A22, A23, and A24 were started in February.3. Direct materials used during February were $150,000.4. Direct labor costs for February were $120,000.5. Actual overhead costs for February were $102,000.6. On February 28, Job A24 was the only job still in process, and it had incurred direct materials costs of $20,000 and direct labor costs of $40,000.As each job is completed, its cost is transferred to the Cost of Jobs Billed account. Each month, Jefferson closes any under-or over-allocated overhead to Cost of Jobs Billed.1. Give one example of a direct cost and one example of an overhead cost for a job undertaken by Jefferson Company.2. Calculate the overhead allocated to Job A21 as of February 1.3. Calculate the overhead allocated to Job A24 as of February 28.4. Calculate the under- or overallocated overhead for February.5. Calculate ending balance of jobs still in process as of February 28.6. Compute the Cost of Jobs Billed for February. A rectangle has a length of 7 meters and a width of (25 - 15) meters. What is its area? A researcher in 2024 studies the evolutionary relationships between influenza viruses by comparing the genomic sequences of the viruses found in pigs, ducks, and humans in a given year. When evaluating the viruses that had infected these hosts the previous year, she identifies a cross-species transfer from pigs to ducks in the year 2022. What information supports the hypothesis that cross-species transfer leads to more severe disease in the new host Although 0 dB is often referred to as the lower threshold of human hearing, it is important to realize that the human ear is not equally sensitive to all frequencies of sound. In other words, a particular noise may sound louder or softer depending on the frequency of the sound wave being transmitted. Because of this variation, scientists have defined a unit of loudness, called a phon, to represent the intensity of sound waves with a frequency of 1000 Hz. A 60-phon sound is one that is perceived by the human ear to have the same loudness as a sound wave with an intensity of 60 dB and a frequency of 1000 Hz.Required:a. At approximately what frequency do most people perceive the least intense sounds? Answer numerically in hertz to two significant figures.b. Normal conversation has a sound level of about 60 dB. How many times more intense must a 100-Hz sound be compared to a 1000-Hz sound to be perceived as equal to 60 phons of loudness? You want to have $10,000 in your account after five years.

When I was little, animals took on lives and characteristics which nobody knew anything about except myself. Little things that people did or said grew into fantastic stories. There was a man who turned into an alligator for my amusement. All he did was live in a one-room house by himself down near Lake Belle. He came into the village one evening near dusk and stopped by the store. Somebody teased him that if he did not hurry up and get married, he was liable to go wild, living alone out there. I saw him tending his garden, but I made an image of him in my imagination that was different. In my mind, his work-a-day hands and feet became the claws of an alligator. A tough, knotty hide crept over him, and his mouth became a huge snout with prong-toothed, powerful jaws. I could just see him crawling from his door at night, turning his ugly head from left to right to see who was looking, then gliding down into the dark waters of Lake Belle. When I heard the thunder of bull 'gator voices from the lake on dark nights, I used to whisper to myself, "That's Mr. Pendir! Just listen at him!"What is the reason the author uses the words "Just listen at him!" instead of "Just listen to him"? A) because everyone talks that way when they are little B) because it is how the alligator wanted the girl to talk C) because that is how she would have talked back then D) because the alligators often talked the same way to her if 49 = 7 and 7 = 3 + 4, then 49 = 3 + 4 Should psychologists be asking about group differences (different race, sex, culture, etc.) in intellectual ability?
