The graph above shows 3 enzymes and their activity at different pH levels.
What is the optimal pH for the enzyme Salivary Amylase?
Use evidence from the graph to support your answer.
The optimal pH for Salivary Amylase is 6.9, which supports its maximum activity in the slightly acidic environment of the mouth before the food enters the stomach.
Explanation:The optimal pH for the enzyme Salivary Amylase is 6.9. This optimal pH allows the enzyme to exhibit its maximum catalytic activity. Enzyme activity typically increases with pH up to their optimal point and then decreases with further deviation from this optimum. As enzymes are affected by the environment they are in, Salivary Amylase, which is present in the mouth, functions best at a slightly acidic pH of 6.9, before the food moves to the more acidic environment of the stomach.
The graph shows the activity of different enzymes at different pH levels. To determine the optimal pH for Salivary Amylase, we need to look for the pH value at which the activity is highest for this specific enzyme. From the graph, we can see that the enzyme's activity is highest at pH 7-7.5, which corresponds to its optimal pH. This indicates that Salivary Amylase works most efficiently at a slightly acidic pH.
The optimal pH for the enzyme Salivary Amylase is around 6.9. It breaks down cooked starch into maltose in the mouth, but its activity is deactivated in the stomach.
Explanation:The optimal pH for the enzyme Salivary Amylase is around 6.9, as indicated in the information provided. Salivary amylase is responsible for breaking down cooked starch into maltose in the mouth. However, its activity is deactivated in the stomach due to the presence of hydrochloric acid (HCl) and the activation of pepsinogen to pepsin.

What is the average rate of change from x=-1 to x=2? -3, -1, 1, 24
The average rate of change of the given function from x = -1 to x = 2 is -1.
The average rate of change of a function between two points, x = a and x = b, is calculated as the difference in the function values at these points divided by the difference in x-values, which is similar to the slope formula for a linear function (gradient).
In this case, we are looking for the average rate of change of f(x) = x^4 - 2x^3 from x = -1 to x = 2. Using the table provided:
f(-1) = 3
f(2) = 0
So, the average rate of change is:
(f(2) - f(-1)) / (2 - (-1)) = (0 - 3) / (2 - (-1)) = (-3) / 3 = -1.
What is the sum of the polynomials?
(m + n + 3) + (m + n + 4)?
Answer:
The sum of of the polynomials (m + n + 3) + (m + n + 4) is 2m + 2n +7
Step-by-step explanation:
The given expression is (m + n + 3) + (m + n + 4)
we need to find the sum of this expression
so, first we add the similar terms
m + n + 3 + m + n + 4
first write the like term together and then constant,
⇒ m + m + n + n +3 + 4
⇒ 2m + 2n +3 + 4
⇒ 2m + 2n +7
Therefore, The sum of of the polynomials (m + n + 3) + (m + n + 4) is 2m + 2n +7
What is the difference between the ratio AP:PB and the ratio of AP:AB?
A line segment can be divided into subsegment using ratios. The difference between [tex]AP:PB[/tex] and [tex]AP: AB[/tex] is that:
Ratio [tex]AP:PB[/tex] compares the two subsegments of AB while Ratio [tex]AP: AB[/tex] compares a segment of AB to the whole length of AB.Given:
[tex]AP:PB[/tex] and [tex]AP: AB[/tex]
In [tex]AP:PB[/tex], we can see that AP and PB has a common point (P).
This means that:
[tex]AB = AP + PB[/tex]
i.e. AP and PB are two subsegments of line segment AB.
So, the ratio [tex]AP:PB[/tex] compares the two subsegments of AB
Because AP and PB are two subsegments of line segment AB.
Then, ratio [tex]AP: AB[/tex] compares a segment of AB to the whole length of AB.

Which number line correctly shows 4.5 – 2.5?
Answer: First option is correct.
Step-by-step explanation:
Since we have given that
[tex]4.5-2.5[/tex]
According to the number line,
First we go 4.5 units towards the positive axis of x from the origin.
And then back by 2.5 units from there towards the negative axis of x to show the subtraction.
So, it will interpretate the subtraction of 2.5 from 4.5.
Numerically, it is expressed as
4.5-2.5=2
So, It should reach at 2 in the positive axis of x.
Hence, First option is correct.
A number line that correctly shows 4.5 – 2.5 is: A. number line A.
What is a number line?In Mathematics and Geometry, a number line refers to a type of graph that is composed of a graduated straight line, which typically comprises both negative and positive numerical values (numbers) that are located at equal intervals along its length.
This ultimately implies that, every number line would primarily increase in numerical value towards the right from zero (0) and decrease in numerical value towards the left from zero (0).

If the shadow of a tree is 14 m long and the shadow of a person who is 1.8 m tall is 4 m long, how tall is the tree?
Which of the following proportions could not be used to solve the problem?
a: 14/1.8=x/4
b: x/14=1.8/4
c: x/1.8=14/4
Answer: [tex]\frac{x}{14}=\frac{1.8}{4}[/tex]
Step-by-step explanation:
Let 'x' be the height of tree.
The length of shadow of a tree = 14 m
The length of shadow of a person =4 m
The height of person = 1.8 m
Since both man and tree are standing vertical to the ground.
Assume the formation of shadow is happening at the same time then the angle that the sun hits the earth making shadows of both person and tree will be equal.
By direct proportion , we have
[tex]\frac{\text{height of tree}}{\text{length of shadow of tree }}=\frac{\text{height of person}}{\text{length of shadow of person}}\\\\\Rightarrow\frac{x}{14}=\frac{1.8}{4}[/tex]
The correct answer would be:
14/1.8 = x/4

Monique Fournier deposited $12,500 into a savings account paying 6.5% annual interest compounded monthly. What amount will she have in her account after 3 years
Follow below steps;
Monique Fournier wants to find out how much her $12,500 savings account, with an annual interest rate of 6.5% compounded monthly, will grow to after 3 years. To calculate the future value of this investment, we can use the compound interest formula:
FV = P times (1 + r/n)^(nt)
Where:
FV is the future value of the investmentP is the principal amount ($12,500)r is the annual interest rate (6.5% or 0.065 as a decimal)n is the number of times interest is compounded per year (12, since it's compounded monthly)t is the number of years the money is invested (3 years)Plugging the numbers into the formula gives us:
FV = $12,500 times (1 + 0.065/12)^(12 imes 3)
After calculating, Monique's account balance after 3 years will be:
FV = $12,500 times (1 + 0.0054167)^(36)
FV = $12,500 times 1.0054167^36
FV ≈ $12,500 times 1.214669
FV ≈ $15,183.36
After 3 years, Monique Fournier will have approximately $15,183.36 in her savings account
