How many peptide bonds are present in a polypeptide that contains 45 amino acids?

Answers

Answer 1

44 peptide bonds. There are n-1 peptide bonds, where n is the amount of amino acids. This is because there are two termini on a polypeptide that makes it "hang off." It is like linking up a chain, if there are two that must bond together then they cannot bond with another chain, therefore there is always one less bond than the total amount of amino acids.

Answer 2

Final answer:

A peptide bond forms between two amino acids by a dehydration synthesis reaction. The number of peptide bonds in a polypeptide is always one less than the total number of amino acids. Therefore, in a polypeptide with 45 amino acids, there would be 44 peptide bonds.

Explanation:

A peptide bond is a chemical bond that forms between two amino acids when a carboxyl group of one amino acid reacts with the amino group of the other amino acid, releasing a molecule of water. This is a dehydration synthesis reaction, and it is how amino acids are linked together to form a polypeptide.

In a polypeptide chain, the number of peptide bonds present is always one less than the total number of amino acids. This is because each amino acid has one peptide bond with the next amino acid in the chain, except the last one. Hence, for 45 amino acids, there would be 44 peptide bonds.

The height of a triangle is one-third of its base. If the height is 9 ft, what is the area of the triangle?

Answers

The height is 1/3 of its base. So, 9 = 1/3 of the base. So, the base is 27.

We know that the formula for area of a triangle is 1/2(b)(h)

So, 1/2(27)(9) = 121.5

So, the area of the triangle is 121.5

im using the * for multiplication

Answer:

a) Expression 1 = 29.833

b) (5+4) * 2 + 6 -2 * 2 - 1

Step-by-step explanation:

In expression 1 we have to know that the order to solve operations is:

First parenthesis, then multiplication and division and then addition and subtraction.

So we have the expression:

6*7-3/2*9+4/3

We first solve multiplications and divisions:

42-1.5*9+1.34

42-13.5+1.34 = 29.84

b) The parenthesis is the operation that goes first so if we insert the parenthesis in 5+4 we will get the next result:

(5+4) * 2 + 6 - 2 * 2 - 1

We have to solve parenthesis first, then multiplication and division and then addition and subtraction:

(9) * 2 + 6 - 4 - 1

18+6-4-1 = 19

We get the number 19.

Answer:

3y+4x=5

Step-by-step explanation:

step 1

Find the slope

we have

(–7, 11) and (8, –9)

m=(-9-11)/(8+7)

m=-20/15

m=-4/3

step 2

Find the equation of the line into point slope form

we have

m=-4/3

point (-7,11)

substitute

y-11=-(4/3)(x+7) ----> equation of the line into point slope form

Multiply by 3 both sides

3y-33=-4(x+7)

3y-33=-4x-28

3y+4x=33-28

3y+4x=5 -----> equation of the line into standard form

students collected 600 cans for the canned food drive that was 80% of their goal how many more cans do they need to collect to reach their goal

Answers

I think it's 1080 cans

Answer: 150

Step-by-step explanation:

Let x be the total number of cans that was students' goal.

Given : Students collected 600 cans for the canned food drive that was 80% of their goal .

We can write 80% as 0.80

Then, we have

[tex]0.80x=600\\\\\Rightarrow\ x=\dfrac{600}{0.80}=750[/tex]

Thus, The students' goal of collecting cans for the canned food drive = 750 cans

Now, the number of food cans required to collect to reach the goal= 750-600=150

suppose the block factory has only crates ans stacks . how can it pack an order for 4,270 blocks

Answers

Final answer:

To pack an order for 4,270 blocks using crates and stacks, you will need 43 crates and 27 stacks.

Explanation:

To pack an order for 4,270 blocks using only crates and stacks, you could use a combination of both. First, determine the number of crates you will need. Since each crate holds 100 blocks, divide 4,270 by 100 to get 42.7. Since you can't have a fraction of a crate, you will need 43 crates.

Next, find out how many blocks are left after packing the crates. Subtract the number of blocks used in the crates (43 crates x 100 blocks) from the total number of blocks (4,270 blocks). You will be left with 4,270 - (43 x 100) = 270 blocks.

Now, you can use stacks to pack the remaining blocks. If each stack can hold 10 blocks, divide 270 by 10 to get 27 stacks. Therefore, you will need 43 crates and 27 stacks to pack an order for 4,270 blocks.

Baseball cards come in packages of 8 and 12. Brighton bought some of each type for a total of 72 baseball cards. How many of each package did he buy?

Answers

3 packs of 8 and 4 packs of 12.

3 x 8 = 24
4 x 12 = 48

24 + 48 = 72

Depending on weather it is a package of 8 or 12 if it were 8 then he would need 12 packages because 8 times 12 is 72 and if it were 12 he would need 8 because 12 times 8 is still 72.

There are 360 smokers in group of 400 smokers began smoking before they reached their 21st birthday.

What is Proportional?

Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.

Given that;

Approximately 9 out of 10 smokers began smoking before the age of 21.

Now,

Let number of smokers in group of 400 = x

Since, approximately 9 out of 10 smokers began smoking before the age of 21.

Hence, Number of smokers in group of 400 is,

⇒ 9 / 10 = x / 400

Solve for x as;

⇒ 9 × 400 / 10 = x

⇒ 9 × 40 = x

⇒ x = 360

Thus, There are 360 smokers started before they reached their 21st birthday.

Wilson goes hiking every 9 days and swimming every 6 days .He did both of the kind of exercise today how many days from now will you go both hiking and swimming again LCM

Answers

To do this, we need to find the LCM of 6 and 9. This can be found by listing out some multiples of each and then finding the first one they have in common:

Multiples of 6: 0, 6, 12, 18, 24, 30, 36
Multiples of 9: 0, 9, 18, 27, 36, 45

The first multiple they have in common is 18, so that is the amount of days until he will hike and swim on the same day. Note that both lists have 36, but this is not the answer since it is not the smallest multiple that they have in common.

Why have all the rates of change in this assignment been negative? Explain.

Answers

The problems have involved going down a waterslide.

To model a slide, you start at the highest point and then decrease as you move down the slide.

The rate of change has compared a drop or decrease in vertical height to an increase in either time or horizontal distance.

The rates of change is negative because the assignment involved the model of a waterslide with a downward slope.

Negative Rate of Change

A negative rate of change would occur if the output decreases as the input increases, and vice versa.

For a model slide, the highest point is plotted first, and going down the waterslide shows a negative slope.

Therefore, the rates of change is negative because the assignment involved the model of a waterslide with a downward slope.

Okay. So,to solve this, we should set up a proportion. 20/9 = 30/x. Do some cross multiplication to get 20x = 270. Now, divide each side by 20 to isolate the x. 270/20 is 13.5.

Graphing the function using the x- and y-intercepts

From the question, we have the following parameters that can be used in our computation:

y = 1/4x - 2

To find the x-intercept, set y to 0 and solve for x:

0 = 1/4x -2

1/4x = 2

x = 8

So the x-intercept is (8, 0).

To find the y-intercept, set x to 0 and solve for y:

y = 1/4 * 0 - 2

y = -2

So the y-intercept is (0, -2).
