Do you need to know if this organism grows anaerobically? if so, why? how would you determine if this organism grows anaerobically? (1 pt)

[ad_1]

Answered by answersmine AT 22/10/2019 – 02:31 AM

It is important to determine or know whether an organism is aerobic or anaerobic because from there you would be able to know the perfect conditions for the organism to grow and reproduce. If you are culturing the organism you would need if it needs oxygen and how much of oxygen is needed. Anaerobic organisms does not need the presence of oxygen in order to grow. You can determine an organism that is anaerobic by trying to put them in conditions that dos not have oxygen. After a few hours or days, when you observe that more organisms are present, then most likely it is an anaerobic organism.

Li designed a survey to determine how comfortable students at her middle school are with fractions. There are 600 students in her middle school. The students are equally distributed among grade levels. She selected a sample of 28 students in her first-period class. Which best explains Li’s sample?

[ad_1]

The correct answer to this is:

Nonrandom and biased

 

The method of Li’s sampling has a
tendency that some elements or portion in the population has no chance of
selection. Further, it was not stated which portion of the population she
obtained the sample thus we cannot accurately determine the probability of
selection. This kind of sampling results in a bias. A biased sampling is a type
of nonrandom sampling.

Karyotypes can be studied to determine an organism’s chromosomal makeup and to detect genetic defects. Turner syndrome occurs when a female has an incomplete set of sex chromosomes. Symptoms of Turner syndrome include swollen hands and feet, short stature, and infertility. Which type of chromosomal mutation is responsible for causing Turner syndrome

[ad_1]

Aneuploidy is the type of chromosomal mutation that is responsible for causing Turner syndrome.

Aneuploidy is a type of chromosomal mutation in which there is presence of an abnormal number of chromosomes in a cell. The chromosomes may be incomplete (missing) or excessive (extra). For example, if a human cell had 42 sex chromosomes instead of 46, or it had 48 chromosomes instead of 46, it is said to be anueploidic in nature. Aneuploidy occurs during cell division when there is improper separation of the chromosomes between the two cells. Aneuploidy is responsible for many genetic disorders including Turner syndrome.

Best answer get Brainliest. 50 points. Emerson earns money from walking dogs and answering surveys. He earns $5 a week for each dog he walks and $0.10 for each survey he answers. Last week, Emerson answered 100 surveys and earned $35. Part A: Create an equation that will determine the number of dogs he walked. (3 points) Part B: Solve this equation justifying each step with an algebraic property of equality. (6 points) Part C: How many dogs did Emerson walk last week? (1 point)

[ad_1]

Step-by-step explanation:

5x + 10 = 35 is your equation

5x = 35 – 10    bc u brought the 10 to the other side so its symbol changes

5x = 25         now were going to bring 5 to the other side to do that we have to divide both sides by 5 (same thing like the 10)

5x/5 = 25/5

x = 5

Describe how you would determine whether two lines are parallel by looking at the equations of the lines in standard form.

[ad_1]

Answer:

By comparing the slopes of both lines.

Step-by-step explanation:

The general form of a straight line is y = mx + c where m is the slope of the line and c is the y-intercept of the line.

For e.g. Consider, the lines y = 2x – 3 and y = 2x – 7.

Now, by comparing these lines with the general form, we get that both of them have slope 2.

Also, by the graph below it can be seen that they both are parallel.

So, it is clear that ‘The slopes of two parallel lines are same’.

Hence, by looking at the standard form of the equation and comparing the slopes, we can determine whether the lines are parallel or not.

The function h(x) = x2 + 14x + 41 represents a parabola. Part A: Rewrite the function in vertex form by completing the square. Show your work. (6 points) Part B: Determine the vertex and indicate whether it is a maximum or a minimum on the graph. How do you know? (2 points) Part C: Determine the axis of symmetry for h(x). (2 points)

[ad_1]

Answered by answersmine AT 22/10/2019 – 03:50 AM

Given the function h(x)=x^2+14x+41, to solve by completing square we procced as follows;
x^2+14x+41=0
x^2+14x=-41
but;
c=(b/2)^2
and b=14
hence;
c=(14/2)^2=49
substituting the value of c in the expression we get:
x^2+14x+49=-41+49
x^2+14x+49=8
(x+7)^2=8
this can be written in vertex form;
h(x)=a(x-h)^2+k
where:
(h,k) is the vertex;
thus
(x+7)^2=8
h(x)=(x+7)^2-8
hence the vertex will be at the point:
(-7,-8)

Determine whether the function is linear or quadratic. identify the quadratic, linear, and constant terms y= (x-5)(5x+4)-5x^2

[ad_1]

Linear means that it is 1st degree, means it has x¹ basically the highest number is 1 for the power of the placeholder

quadratic means it is 2nd degree, means it has x² in it

so expand and simlfiy
(x-5)(5x+4)-5x²=
5x²-21x-20-5x=
-21x-20

so y=-21x¹-20
it’s linear because the squared terms cancel each other out

Which represents the solution(s) of the system of equations, y = x2 – 4x – 21 and y = –5x – 22? Determine the solution set algebraically. (–1, –17) (1, –27) (–1, –17) and (1, –27) no solutions

[ad_1]

Answer:

No solutions

Step-by-step explanation:

We have been given the system of equations

y=x^2-4x-21....(1)\y=-5x-22.....(2)

Substituting the values y from (2) in (1)

-5x-22=x^2-4x-21\x^2+x+1=0\

Let us find the discriminant of this quadratic equation

D=b^2-4ac\D=1^2-4(1)(1)\D=1-4\D=-3

Since, D is negative. Hence, there will not be any real zeros.

It means we’ll not get any real values for x.

Therefore, there is no solution for the given system of equations.

From the table below, determine whether the data shows an exponential function. Explain why or why not. (x) -5, -4, -3, -2 (y) 0.5, 2, 8, 32 A) Yes; the domain values are at regular intervals and the range values have a common factor 8. B) Yes; the domain values are at regular intervals and the range values have a common factor 4. C) No; the domain values are not at regular intervals. D) No; the domain values are at regular intervals and the range values have a common factor 4. Please help, and please give me an explanation on the answer you choose because I need to make corrections. Please.

[ad_1]

Answer:

Option B-  Yes; the domain values are at regular intervals and the range values have a common factor 4.

Step-by-step explanation:

Given : The data

(x) -5,   -4,  -3,   -2

(y) 0.5,  2,   8,   32

To find : The data shows an exponential function or not

Solution :

The general form of an exponential form is y=ab^x

To check whether the data give the exponential function we form equation with the help of two points and verify the other two points .

y=ab^x

Let x= -5 and y=0.5

0.5=ab^{-5}

frac{0.5}{b^{-5}}=a ……[1]

Let x= -4 and y=2

2=ab^{-4}

frac{2}{b^{-4}}=a ………[2]

Equate LHS because RHS is equal in equation [1] and [2]

frac{2}{b^{-4}}=frac{0.5}{b^{-5}}

frac{b^{-4}}{b^{-5}}=frac{2}{0.5}

b=4

Put back in [2]

frac{2}{4^{-4}}=a .

a=2times4^4

a=2times256=512

a=512 and b=4

Exponential function – y=4(512)^x

To verify this function put

1) x=-3

y=512(4)^{-3}

y=farc{512}{64}

y=8

The point satisfied.

2) x=-2

y=512(4)^{-2}

y=farc{512}{16}

y=32

The point satisfied.

Therefore, The given data is an exponential function y=4(512)^x

The domain values are at regular intervals and the range values have a common factor 4 because b=4 and the change happen but value of b remain same.

Hence, Option B is correct.

Yes; the domain values are at regular intervals and the range values have a common factor 4.
