What is the function of proteins and carbohydrates that are embedded in a cell membrane


Answered by answersmine AT 22/10/2019 – 04:26 AM

Carbohydrates covalently linked to proteins (glycoproteins) or lipids (glycolipids) are also a part of cell membranes, and function as adhesion and address loci for cells. The Fluid Mosaic Model describes membranes as a fluid lipid bilayer with floating proteins and carbohydrates.

The brain mass of a fetus can be estimated using the total mass of the fetus by the function b equals 0.22 m superscript 0.87b=0.22m0.87?, where m is the mass of the fetus? (in grams) and b is the brain mass? (in grams). suppose the brain mass of a 2323?-g fetus is changing at a rate of 0.240.24 g per day. use this to estimate the rate of change of the total mass of the? fetus, startfraction dm over dt endfraction dm dt.


We are given
b = 0.22 m^0.87
db/dt = 0.24 g/day at b = 23 g

where
b is the brain mass of the fetus
m is the total mass of the fetus
db/dt is the rate of change of the brain mass of the fetus

We are asked to get the rate of change of the total mass of the fetus

First, we take the first derivative of the given equation with respect to time
db/dt = 0.22 (0.87) m^(0.87-1) dm/dt
Next, simplify and substitute the given values. So,
0.24 g/day = 0.22(0.87)(23)^(0.87 -1 ) dm/dt
Solving for dm/dt
dm/dt = 1.88 g/day

The rate of change of mass of the fetus is 1.88 g/day.

Given the range of the function, find the corresponding domain. f(x) = 4x – 1 Range: {3, 7, 11, 15}


The range is the output value or the y value.
You would work backwards to find the domain.

f(x) = 4x – 1                              f(x) = 4x – 1
3 = 4x – 1                                    7 = 4x – 1
add 1 to both sides                    add 1 to both sides
4 = 4x                                            8 = 4x
divide both sides by 4              divide both sides by 4
x = 1                                              x = 2

f(x) = 4x – 1                                  f(x) = 4x – 1
11 = 4x – 1                                      15 = 4x – 1
add 1 to both sides                      add 1 to both sides
12 = 4x                                              16 = 4x
divide both sides by 4                  divide both sides by 4
x = 3                                                    x = 4
Domain { 1, 2, 3, 4}

A function is shown below: f(x) = (0.07)x What does the function represent? Exponential growth of 7% Exponential decay of 7% Exponential growth of 93% Exponential decay of 93%


Answer:

Exponential decay of 93%

Step-by-step explanation:

A function is shown below:

f(x) = (0.07)^x

Exponential formula is

f(x)= a(1+r)^t

r is the rate of growth or decay

From the given f(x) , we have 1+r = 0.07

Subtract 1 from both sides

r= 0.07 -1

r= -0.93

To get % we multiply by 100

r= -93%

the value of ‘r’ is negative , so its exponential decay

Exponential decay of 93%

If Denise wanted to create a function that modeled an exponential function with base of 12 and what exponents were needed to reach specific values, how would she set up her function? f(x) = x12 f(x) = log12x f(x) = 12x f(x) = logx12


Denise creates the exponential function g(x)=12 ^{x}

assume she want to find for what value of x, her function reaches the value, 3, or 8.2, or any value a (larger than 0)

so she shants to solve 12 ^{x}=a   (“for what value of x, is 12 to the power of x equal to a?”)

this expression is equivalent to x=log_1_2(a)

(so 12 to the power of x is a, for x=log_1_2_(a))

we can generalize this result by creating a function f.

In this function we enter x, the specific value we want to reach. f will calculate the exponent needed, in the following way:

f(x)=log_1_2(x)  

(example: we want to calculate at which value is  12^{x} equal to 5?
answer: f(x)= log_1_2(5),

check: 12^{log_1_2(5)} =5, which is true, by properties of logarithms)

Answer: log_1_2(x)       (B)

Answer:

5 in 0.05 is 10 times greater than 5 in 0.005.

Step-by-step explanation:

To find : In which number does the digit 5 have greater value 0.05 or 0.005 how many times as great is it and how do you know ?

Solution :

According to the place value stem,

Ones      Tenths      Hundredths     Thousandths

 0              0                   5                                           – 0.05

 0              0                   0                        5                 – 0.005

In 0.05 5 is in hundredths place and in 0.005 5 is in thousandths place.

So, 5 in 0.05 is 10 times greater than 5 in 0.005.

As 0.05=5times frac{1}{100}

0.005=5times frac{1}{1000}

Answer:

Number of copy machines must be made to minimize the unit cost=160.

Step-by-step explanation:

We are given that the unit cost function C ( the cost in dollars to make each copy machine)

If machines are made =x

Then the unit cost function is given by

C(x)=0.8x^2-256x+25939

We have to find the number of copy machines for  minimize the unit  cost

C(x)=0.8x^2-256x+25939

Differentiate with respect to x

Then we get

frac{mathrm{d}C}{mathrm{d}x}=1.6x-256 ……(equation I)

To find the value of x then we susbtitute frac{mathrm{d}C}{mathrm{d}x} is equal to zero

frac{mathrm{d}C}{mathrm{d}x}=0

1.6x-256=0

1.6x=256

x=frac{256}{1.6}

By using division property of equality

x= 160

Again differentiate the equation I with respect to x then we get

frac{mathrm{d}^2 C}{mathrm{d}^2 x}=1.6 >0

Hence, the unit cost is minimize for x=160

Therefore, the number of copy machines must be made to minimize the unit cost =160

So, if you are told that one term of the polynomial is 9 x ^ (negative something), it is necessary that the number after the negative sign be negative, given that negative times negative is positive.

Therefore, the only possible option from the answer choices is the option 3) -9.

What is the inverse of the function f(x)=x-12


Answer: The answer is (C) Patricia is not correct because both 3 – 4i  and -11+√2i  must be roots.

Step-by-step explanation:  Given that  (-11-√2i) , (3 + 4i), and 10 are the roots of the polynomial function f(x) that Patricia is studying.

We know that the complex roots of a polynomial function always occur in pairs. That is, if (a + bi) is a root of a function, then (a – bi) will also be a root (one is the complex conjugate of the other).

The complex conjugate of (3 + 4i) is (3 – 4i) and the complex conjugate of (-11 – √2i) is (11 + √2i).

Therefore,  (3 – 4i) and (-11 + √2i) both are the roots of f(x).

Hence, since we have 5 roots, so the degree of the polynomial function f(x) cannot be 4.

Since Patricia concludes that the degree of f(x) is 4, so she is not correct because both (3 – 4i)  and (-11+√2i)  must be roots.

Thus, option (C) is correct.

How do prepositions function in a sentence


Answer:

Your answer would be that the correct version of the sentence is the following one: My brother took out the garbage, and Motehr was very happy.

Explanation:

You should capitalize words such as Mother, Father, Brother, Sister, Grandmother, Son, Daughter when they are used in place of the person’s name. What is more, you should not capitalize them when they follow possessive pronouns (my, your, his, her, our). In the sentence above, Mother is capitalized because it is not preceded by any pronoun, while brother is not because it follows the possessive pronoun my.
