The tiny fruit fly is a superstar of genetics research. Thousands of experiments have explored how flies inherit traits. Wing shape, body color, eye color, and head shape are a few traits under investigation. Fruit flies make good study subjects because they are inexpensive, take little space, and breed quickly. In addition, humans and fruit flies share 75% of their disease genes. By studying fruit-fly genetics, we can learn about human illness.

Short-winged fruit flies studied in the lab cannot fly because they have an allele that causes them to grow tiny wings (w). Normal fruit flies, known as “wild-types”, have fully functional wings (W). The wild-type wing is the dominant allele.
If you cross one short-winged fly (ww) with a wild-type fly (WW), what is the probability of getting a short-winged offspring in the F1 generation?
Explain your reasoning.

Answers

Answer 1

Answer:

a. 0

b. There are no short winged genes expressed in this generation

Explanation:

a. What is the probability of getting a short-winged offspring in the F1 generation?

Since we have the ww gene for the short winged fly and the WW gene for the wild type fly.

In the F1 generation, we have

Ww, Ww, Ww and Ww

Since the W wild-type allele is the dominant gene, in the F1 generation, all the fruit flies have wild-type wing.

Probability of short-winged fly, P(short-winged) = number of short-winged genes/total number of genes =

number of short-winged genes = 0

total number of genes = 4  

P(short-winged) = 0/4 = 0

b. Explain your reasoning.

Since the wild winged type allele is the dominant gene, there are no short winged genes expressed in this generation. Thus, the probability of obtaining a short-winged fly in the F1 generation is therefore zero.

Explain how internal migration contributes to the decline of indigenous language

Answers

Answer:

Due to decrease in the population of people who speaks indigenous language.

Explanation:

Internal migration greatly contributes to the decline of indigenous language because the people who speak the indigenous language migrated to other regions and there are very less number of people who speak that indigenous language so we can say that Internal migration is responsible for the decrease of indigenous language. If we have to promote indigenous language so we have to reduce internal migration of people.

What interesting patterns did you notice between the various stakeholders in relation to the arguments for and against the Keystone XL Pipeline?

Answers

Hello. You did not submit the text to which this question refers, which makes it difficult for it to be answered. However, I will try to help you as best I can.

Keystone XL Pipeline was a pipeline installation project that originated in Canada but extended to the US. The installation of this pipeline was very controversial and spurred people against and in favor of the installation. It was normal that both the people who were against and those who were in favor presented opinion patterns that are opinions that are repeated in each group.

In the group in favor of installing the pipeline, we could see a pattern where people argued that this pipeline would create many jobs, improve countries' economies, and increase the flow of energy and oil in North America. In the group against installation, we could see a pattern, where people claimed that the installation of this pipeline would negatively impact nature and encourage the use of fossil fuels that would stimulate global warming.

A square with sides 8 inches in length has a circle inscribed in it. The circle has a radius of 4. What is the area of part of the square not in the circle.

Answers

16π−32

Explanation:  

To get the area inside the circle but outside the square, we simply get the difference of their areas.

Ac=r2π=42π=16πA square is also a rhombus (with equal diagonals), so we can use the formula for the area of the rhombus. What do we use as the value of the diagonal? The diameter of the circle!As=12d1d2=12d2=12(82)=12(64)=32

Hence, A=16π−32 If you think you won't be able to remember the formula of the rhombus, we can go the usual way of getting the area of the square.As=s2Now, we need to find the length of the side. To do this, we can form an imaginary right isosceles triangle with the radius of the circle as legs and the side as the hypotenuse. How do we know the triangle is right? It's a property of a square, the diagonals form a right angle.Now, we use the Pythagorean theorem to get the side,

c2=a2+b2=2a2=2(42)=32⇒c=4√2

Now we can get the area of the square.As

=s2=(4√2)2=32Hence, A=16π−32

I found a bed bug in my room. I told my mom and she blamed me Bc my room wasn’t clean. Yeah, I been not cleaning up. And she thinks that bed bugs only come at night. So, yesterday I slept in the living room. In the morning I got blamed and she said that’s why you should clean your room. Then I went in my room SCARED Bc my mom told me too, and I’m scared that it would be more. So I went back in the living room, and I felt anxious like I have to throw up. But my mom saw me and said I was being hard headed and I told her I was scared. Then she said that IT NO MORE BED BUGS IT WAS JUST ONE. Also I forgot to tell y’all that my dad look under the my mattress and it wasn’t anymore. BUT BED BUG ALSO HIDE IN OTHER PLACES TOO.

But I need advice, how do I know if there’s anymore bed bugs. Also I never gotten bed bugs before sooo what are the signs? If there is signs what do it look like???

Answers

Answer:

I don't think it was because your room wasn't clean. The main cause of bed bugs is travel, which means most likely you got one on you when you went outside or something, and you accidentally got it into your room. Bed bugs hitchhike on luggage, clothing, people, etc.

If there are blood stains or dark/rusty spots on your bed/pillow, there are definitely bed bugs. The bloodstains/spots come from you crushing the bed bugs accidentally. The place where bed bugs are (in this case, your room), may also begin to smell bad. You might also see eggs laid by the bed bugs.

Let me know if you have any other questions. Good luck!

Answers

Answer:

1,437.33

Explanation:

Volume of a sphere = 4/3πr³

π = 22/7

r = 7

Volume of a sphere = 4/3πr³

= 4/3 * 22/7 * 7³

= 4/3 * 22/7 * 7 * 7 * 7

= (4 * 22 * 7 * 7 * 7) / (3 * 7)

= 30,184/21
