In pea plants, flower color is inherited in a Mendelian fashion. Purple flowers (P) are dominant over white flowers (p). If two

RideAnS [48]

Answer:

25%

Step-by-step explanation:

The crossing between two heterozygous purple flowers can have the following results:

P from 1st flower and P from 2nd flower: PP -> 25% chance

P from 1st flower and p from 2nd flower: Pp -> 25% chance

p from 1st flower and P from 2nd flower: Pp -> 25% chance

p from 1st flower and p from 2nd flower: pp -> 25% chance

As the purple flower gene is dominant over the white flower, to have a white flower we need to have only white flower's genes, that is, pp.

So, the probability of the offspring will have white flowers is 25%

The graph of y^2=x^2 is symmetric with respect to which axis? a. x-axis c. both b. y-axis d. neither

PtichkaEL [24]

Answer:

c. both

Step-by-step explanation:

Given equation is $y^2=x^2$

Now we need to check if the graph of $y^2=x^2$ is symmetric with respect to which axis?

a. x-axis c. both b. y-axis d. neither

We know that if f(-x) reflect the graph about y-axis

so let's change x by -x into given function to see if that equation remains unchanged or not

$y^2=(-x)^2$

$y^2=x^2$

That is same as previous equation.

<u>Hence given graph is symmetric about y-axis.</u>

We know that if -f(x) reflect the graph about x-axis

so let's change y by -y into given function to see if that equation remains unchanged or not

$(-y)^2=x^2$

$y^2=x^2$

That is same as previous equation.

<u>Hence given graph is symmetric about x-axis.</u>

So the correct choice is c. both

What would be the difference at the end of one year between the simple interest earned on a deposit of $450 at 4.5% and the comp

Len [333]

Answer: $0

Step-by-step explanation:

The formula for simple interest is expressed as

I = PRT/100

Where

P represents the principal

R represents interest rate

T represents time in years

I = interest after t years

From the information given

T = 1 year

P = $450

R = 4.5%

Therefore

I = (450 × 4.5 × 1)/100

I = 2025/100

I = 20.25

For compound interest,

Initial amount deposited into the account is $450 This means that the principal,

P = 450

It was compounded annually. This means that it was compounded once in a year. So

n = 1

The rate at which the principal was compounded is 4.5%. So

r = 4.5/100 = 0.045

It was compounded for just a year. So

t = 1

The formula for compound interest is

A = P(1+r/n)^nt

A = total amount in the account at the end of t years. Therefore

A = 450 (1+0.045/1)^1×1

A = 450(1.045) = $470.25

Compound interest = 470.25 - 450 = 20.25

The difference is 20.25 - 20.25 = 0
