## Which of the following involves mitotic cell division? A. Sexual reproduction B. Asexual reproduction C. Production of gametes D. Production of a fertilized egg

The correct answer is option B.

Explanation:

Mitosis is a type of cell division, of nuclear division in cells that takes place when a single parent cell divides to produce 2 exact similar daughter cells. Mitosis refers to the separation of the replicated genetic matter carried in the nucleus.

It is the process of forming an individual from a single parent. The whole organism as such is reproduced by a single parent. Mitosis involves asexual reproduction by dividing the cells that result in forming a new organism from the pre-existing parent cell.

Thus, the correct answer is option B.

## Which is an example of a chemical change? A) frying an egg B) boiling water C) melting butter D) chopping onions

The equation for how temperature changes the resistance R is:

R=R₀(1+α(T-T₀)), where R₀ is the resistance at T₀=20°C, T is the temperature for which we want to calculate the resistance and α is the temperature coefficient for resistance.

The resistance of the copper wire increases by 18% or by 0.18, so the new value for the resistance is R=1.18*R₀.

T₀=20°C
=0.0068
R=1.18*R₀

Now we need to input that into the equation for resistance change and solve for temperature T.

1.18R₀=R₀(1+α(T-20)), R₀ cancels out,

1.18=1+α(T-20),

1.18-1=α(T-20), we divide by α,

0.18/α=T-20, we put 20 on the left side,

26.47+20=T

T=46.47°C

So the temperature on which the resistance of copper wire will increase by 18% is T=46.47°C.

## The condition resulting from a fertilized egg implanting in the Fallopian tube is called

Charlie had a waist circumference of 47 inches and a BMI of 29 this shows that she is overweight. BMI test level is high from normal ranges shows that she is at higher risk of disease. She should lose weight and concern to the doctor.

Further Explanation:

Body mass index (BMI) is a measured value derived from the height of a person and mass.

BMI indicates whether the person is healthy or overweight mainly used by physicians.

• Range of BMI in a normal person is 18.5-25

• Range of BMI in skinfold person is 25-30

• Range of BMI in underweight person is 15-18.5

The skinfold measurement test is used to determine a person’s body fat percentage and body composition.

In this test, we are the proportion of body fat by determining skinfold thickness at pinches specific part of the body. The estimate of these folds is determined the fat beneath the skin, also called subcutaneous adipose tissue.

The tester pinches the skin at the site and drags the fold of skin away from the muscle so only the fat tissue and skin are being held. The skinfold thickness is measured by skinfold calipers in millimeters.

Skin test includes the seven locations of the body:

1. Triceps

3. Suprailiac

4. Pectoral

5. Subscapular

6. Midaxilla

7. Abdomen

Charlie had a waist circumference of 47 inches and a BMI of 29 this shows that she is overweight. Females with waist size 47 inches have higher risk of having disease. BMI test level is high from normal ranges shows that she is at higher risk of disease.She should lose weight and concern to the doctor.

The integumentary system covers the surface of the body is true about the integumentry system.

Explanation:

The integumentary system includes the skin, nails, glands, hairs, and nerves. Its main role is to act as a barrier to protect the body from the outside environment. It also retains body fluids, regulates body temperature, eliminates waste products, and protects against disease.

The integumentary system is the largest organ in the body that covers the surface of the body.

Thus, The integumentary system covers the surface of the body is the true statement about the integumentry system.

## A blastocyst is a A. cluster of cells surrounding a developing egg in the uterus. B.membrane that surrounds and protects a growing embryo in the uterus. C. growth that can form in the wall of the fallopian tubes. D. hollow ball of cells formed after a fertilized cell undergoes cell division.

The right answer is Transgenic organisms can produce a desired product that may benefit other organisms.

A transgenic organism contains DNA combining  stably integrated in all its cells. In other words, the organism, be it a plant, an animal or a microorganism, has a new piece of DNA embedded in it. a chromosome in each of its cells. This “new piece” of DNA usually contains a gene from another organism (plant, animal or other) that has been modified to be expressed in the new  organization. A transgenic organism may even possess the DNA of another organism of the same species. The inserted gene can be called the transgene.

Currently, diabetics are treated by injecting insulin from either a healthy human donor or cultures of genetically modified (transgenic) bacteria that secrete the protein.

Explanation:

From 1927, the Soviet Union introduced the concept of collective farms. The purpose of collectivization was to make individual lands and labor pass to collective farms, called kolkhozes. The workers received no wages but received part of what they produced on the farm, just to cover their needs and those of their families. Soviet leaders hoped that collectivization would significantly increase the food supply for the urban population, meaning that at that time it was believed that collective farms were the most efficient way to produce food.

This was not the case, however, and collective farms proved to be a major problem.

Collectivization created a profound trauma for the Russian peasantry. The forced confiscation of meat and bread led to riots. There were even peasants who chose to sacrifice their cattle rather than hand them over to collective farms. Sometimes the Soviet government used the army to suppress the revolts.

The ancient traditions of the Russian peasantry were eventually destroyed in the process. The peasants, who used to be interested in the fruits of their work, were losing interest in the kolkhozes. The early years of collectivization proved catastrophic. In 1932 and 1933 there was a great famine in the country that claimed the lives of eight million people, largely due to collectivization.

## You check 20 cartons of eggs 3 of the cartons have at least 1 cracked egg what is the experimental probability that a carton of eggs had at least 1 cracked egg

8 packages

8 jars of sauce

Step-by-step explanation:

As you need just the same amount of pasta and sauce, you only need to create an equation, you can represent the sauce with an x and the pasta with a Y, so your equation would be:

3x + 1y= 36

since X=Y in number your new equation would be:

3x+ 1x=36

4x=36

x=

x=9

The other equation would be:

1.5x + 1y= 20

Since x equals y the equation will end up like this:

1.5x+1x=20

2.5x=20

x=8

Since 8 is the number that best suits the needs for the carying capacities, and you´ll end up with 3 extra bucks, but you cant buy the 9 and 9 and then can´t carry them in the backpack.

## What is the name for the process in which an ovary releases a ripened egg each month

-Helium nucleus formed, hydrogen nucleus formed, isotope of hydrogen, tritium formed

Explanation;

-Nucleosynthesis is the process of creating new atomic nuclei from preexisting nucleons (protons and neutrons). The primordial preexisting nucleons were formed from the quark-gluon plasma of the Big Bang as it cooled below ten million degrees.

-This first process may be called nucleogenesis, the genesis of nucleons in the universe. The subsequent nucleosynthesis of the elements (including all carbon, all oxygen, etc.) occurs primarily in stars either by nuclear fusion or nuclear fission.

-Stellar nucleosynthesis is the process by which elements are created within stars by combining the protons and neutrons together from the nuclei of lighter elements. All of the atoms in the universe began as hydrogen. Fusion inside stars transforms hydrogen into helium, heat, and radiation. Heavier elements are created in different types of stars as they die or explode.

## Alexandra drops an egg from 30 m above the ground to hit Vanessa on the head. If Vanessa stands 3.5 meters tall. How fast is the egg moving when it strike her head? (Hint: Draw a picture and you will see why you have to consider her height and find the time first!)

Angular momentum is given by the length of the arm to the object, multiplied by the momentum of the object, times the cosine of the angle that the momentum vector makes with the arm. From your illustration, that will be:
L = R * m * vi * cos(90 – theta)

cos(90 – theta) is just sin(theta)
and R is the distance the projectile traveled, which is vi^2 * sin(2*theta) / g

so, we have: L = vi^2 * sin(2*theta) * m * vi * sin(theta) / g

We can combine the two vi terms and get:

L = vi^3 * m * sin(theta) * sin(2*theta) / g

What’s interesting is that angular momentum varies with the *cube* of the initial velocity. This is because, not only does increased velocity increase the translational momentum of the projectile, but it increase the *moment arm*, too. Also note that there might be a trig identity which lets you combine the two sin() terms, but nothing jumps out at me right at the moment.

Now, for the first part…

There are a few ways to attack this. Basically, you have to find the angle from the origin to the apogee (highest point) in the arc. Once we have that, we’ll know what angle the momentum vector makes with the moment-arm because, at the apogee, we know that all of the motion is *horizontal*.

Okay, so let’s get back to what we know:

L = d * m * v * cos(phi)

where d is the distance (length to the arm), m is mass, v is velocity, and phi is the angle the velocity vector makes with the arm. Let’s take these one by one…

m is still m.
v is going to be the *hoizontal* component of the initial velocity (all the vertical component got eliminated by the acceleration of gravity). So, v = vi * cos(theta)
d is going to be half of our distance R in part two (because, ignoring friction, the path of the projectile is a perfect parabola). So, d = vi^2 * sin(2*theta) / 2g

That leaves us with phi, the angle the horizontal velocity vector makes with the moment arm. To find *that*, we need to know what the angle from the origin to the apogee is. We can find *that* by taking the arc-tangent of the slope, if we know that. Well, we know the “run” part of the slope (it’s our “d” term), but not the rise.

The easy way to get the rise is by using conservation of energy. At the apogee, all of the *vertical* kinetic energy at the time of launch (1/2 * m * (vi * sin(theta))^2 ) has been turned into gravitational potential energy ( m * g * h ). Setting these equal, diving out the “m” and dividing “g” to the other side, we get:

h = 1/2 * (vi * sin(theta))^2 / g

So, there’s the rise. So, our *slope* is rise/run, so

slope = [ 1/2 * (vi * sin(theta))^2 / g ] / [ vi^2 * sin(2*theta) / g ]

The “g”s cancel. Astoundingly the “vi”s cancel, too. So, we get:

slope = [ 1/2 * sin(theta)^2 ] / [ sin(2*theta) ]

(It’s not too alarming that slope-at-apogee doesn’t depend upon vi, since that only determines the “magnitude” of the arc, but not it’s shape. Whether the overall flight of this thing is an inch or a mile, the arc “looks” the same).

Okay, so… using our double-angle trig identities, we know that sin(2*theta) = 2*sin(theta)*cos(theta), so…

slope = [ 1/2 * sin(theta)^2 ] / [ 2*sin(theta)*cos(theta) ] = tan(theta)/4

Okay, so the *angle* (which I’ll call “alpha”) that this slope makes with the x-axis is just: arctan(slope), so…

alpha = arctan( tan(theta) / 4 )

Alright… last bit. We need “phi”, the angle the (now-horizontal) momentum vector makes with that slope. Draw it on paper and you’ll see that phi = 180 – alpha

so, phi = 180 – arctan( tan(theta) / 4 )

Now, we go back to our original formula and plug it ALL in…

L = d * m * v * cos(phi)

becomes…

L = [ vi^2 * sin(2*theta) / 2g ] * m * [ vi * cos(theta) ] * [ cos( 180 – arctan( tan(theta) / 4 ) ) ]

Now, cos(180 – something) = cos(something), so we can simplify a little bit…

L = [ vi^2 * sin(2*theta) / 2g ] * m * [ vi * cos(theta) ] * [ cos( arctan( tan(theta) / 4 ) ) ]

## This question is based on the following paragraph. The sentences are numbered to help you answer the question. (1) Making rice pudding can be very easy. (2) First, get a large, heavy saucepan. In the pan, measure 3 cups of whole milk, 1 cup of water, 1/2 stick of margarine or butter, and 1/2 cup of rice. (3) Bring this mixture to a quick boil. (4) Lower heat and slowly simmer for 45 minutes. (5) Remove the saucepan from the heat. (6) Add one beaten egg, 1/2 cup of sugar, and 1/2 teaspoon of vanilla. (7) Stir well. (8) Serve warm or cold. (9) Enjoy your treat. The topic sentence of this paragraph is A. Sentence 2. B. Sentence 3. C. Sentence 1. D. Sentence 4. PLEASE HELP!

The correct answer is B. The story contains a moral.

Explanation:

In literature, parables are usually short didactic stories that include human characters in “real-life” situations that are used to convey a specific moral or lesson about life, behavior, beliefs, etc. This type of literary work is quite similar to fables, but in fables, animals and not humans are the main characters. Additionally, parables are common to depict religious morals or values, although they can be used to convey morals that are not related to religion. Considering this, the sentence that best describes a characteristic of a parable is the story contains a moral, because this is the main purpose of any parable.
