What are the differences in Muscularity?Earthworms usually eats the soil that has organic matter such as leaves and others.
Now, the digestive system of earthworms is made up of pharynx, oesophagus, intestine, gizzard and crop. The mode of digestion is that the food passes through the esophagus after which it is now pushed down the crop where it is used for storage and then in the gizzard where the food is being grind.

A random drawing will determine which 3 people in a group of 9 will win concert tickets. what is the probability that you and your 2 friends will win the tickets? express your answer as a fraction in simplified form.
The probability that you and your 2 friends win the tickets is P = 1/84.
How to determine the probability?
There are 9 possible outcomes, 3 of which are you and your friends.
All of these outcomes have the same probability of being randomly selected, then the probability of winning is given by the quotient between the number of "outcomes" that you have and the total number of outcomes.
Let's say that the outcomes are pieces of paper with the names of the participants.
First draw:
In this one, there are 3 possible options that work, one is your paper, and the other two are for your friends.
So the probability is 3/9 = 1/3.
Second draw.
One of your group already won, so now there are 2 of you, and a total of 8 pieces of paper, so this time the probability is 2/8 = 1/4
Final draw:
Only one of you remains, and there is a total of 7 pieces of paper, this time the probability is 1/7.
The joint probability (of these 3 events happening in succession) is given by the product of the individual probabilities:
P = (1/3)*(1/4)*(1/7) = 1/84

Of 1000 students surveyed, 490 were boys and 320 had bicycles. of those who had bicycles, 130 were girls. what is the probability that a student surveyed was either a boy or had a bicycle?
By definition of probability, the probability that a student surveyed was either a boy or had a bicycle is 62%.
Definition of ProbabitityProbability is the greater or lesser possibility that a certain event will occur.
In other words, the probability is the possibility that a phenomenon or an event will happen, given certain circumstances. It is expressed as a percentage.
Union of eventsThe union of events, AUB, is the event formed by all the elements of A and B. That is, the event AUB is verified when one of the two, A or B, or both occurs. AUB is read as "A or B".
The probability of the union of two compatible events is calculated as the sum of their probabilities subtracting the probability of their intersection:
P(A∪B)= P(A) + P(B) -P(A∩B)
The intersection of events, A ∩ B, is the event formed by all the elements that are, at the same time, from A and B. That is, the event A ∩ B is verified when A and B occur simultaneously.
Events and probability in this caseIn first place, let's define the following events:
A: The event that a student surveyed was a boy.B: The event that a student surveyed had a bicycle.Then you know:
P(A)= [tex]\frac{490}{1000}[/tex]=0.49= 49%P(B)= [tex]\frac{320}{1000}[/tex]= 0.32= 32%P(A and B)= P(A∩B)= [tex]\frac{190}{1000}[/tex]= 0.19= 19% [320 students had bicycles. Of those who had bicycles, 130 were girls. Then, 190 were boys.]In this case, considering the definition of union of eventes, the probability that a student surveyed was either a boy or had a bicycle is calculated as:
P(A∪B)= P(A) + P(B) -P(A∩B)
P(A∪B)= 0.49 + 0.32 -0.19
P(A∪B)= 0.62= 62%
Then, the probability that a student surveyed was either a boy or had a bicycle is 62%.

Describe in detail the most memorable visual aid you've ever seen used in a presentation. why does it stick out in your memory? how was it used to illustrate a point? what did you learn from this experience?
Answer:
Explanation:
The most memorable visual aid I have seen used was when a psychology professor used graphic descriptions (through historically important paintings) to illustrate abstract concepts, such as love, madness, and despair.
The representations used in the presentation stuck in my mind because of the visual impact that correlated with my personal experiences, making them vivid and memorable in my mind.
The points illustrated aimed at demonstrating the universality of human passions, and as such, it was an extremely successful presentation.
Finally, what I learned from this experience is that human emotions are not only universal, and as such, they can be represented, but, also, and most importantly, they are emotions that are not abstract concepts, rather, singular and personal experiences to which, paradoxically, everyone is subjected.

How many grams of calcium oxide will be produced in a closed vessel containing 20.0 kg of calcium and 20.0 kg of oxygen gas if the reaction goes to completion? (atomic mass of calcium = 40.1 amu)
Answer:
Explanation:
The mass of Calcium oxide that will be produced in a closed vessel is 27984.1311 g. The Number of moles is defined as given mass over molar mass.
Calculation of Number of moles:
Number of moles = Given mass / Molar mass
For Calcium :-
Mass of calcium = 20.0 kg = 20000 g ( 1 kg = 1000 g )
Molar mass of calcium = 40.078 g/mol
Thus,
Number of moles = 20000 g / 40.078 g/mol
Number of moles = 499.02 moles
For oxygen gas :-
Mass of oxygen gas = 20.0 kg = 20000 g ( 1 kg = 1000 g )
Molar mass of oxygen gas = 31.999 g/mol
Thus,
Number of moles = 20000 g / 31.999
Number of moles = 625.19 moles
According to the given reaction:
2 moles of calcium reacts with 1 mole of oxygen gas
Also,
1 mole of calcium reacts with 1/2 mole of oxygen gas
So,
499.0269 mole of calcium react with mole of oxygen gas
Moles of oxygen gas = 249.5135 moles
Available moles of oxygen gas = 625.0195 moles
Limiting reagent is the one which is present in small amounts. Thus, calcium is limiting reagent.
The formation of the product is governed by the limiting reagent. So,
2 moles of calcium produces 2 moles of calcium oxide
So,
1 mole of calcium produces 1 mole of calcium oxide
Also,
499.0269 moles of calcium produces 499.0269 moles of calcium oxide
Moles of calcium oxide = 499.0269 moles
Molar mass of calcium oxide = 56.0774 g/mol
Mass of calcium oxide = Moles × Molar mass = 499.0269 * 56.0774 g = 27984.1311 g
27984.1311 g of calcium oxide will be produced.

This source isn't very recent (but it doesnt need to be because Amaya is writing about the history of Europe), but we do know that it was updated, which implies that more relevent information was posted. The information is coming from a trustworthy source (we know this because of the url the article is from), so is likely very relevent and relaible. The last source is irrelevent becasue it's abput a carmaker who had/has nothing to do with the Columbian Exchange, and the first source is from a journal (we don't know who the journal belongs to, or what kind of information is in it).

A beam of white light goes from air into the water droplet at an incidence angle of 36.2 degrees. what is the angle between the red (660 nm) and violet (410 nm) parts of the refracted light?
A beam of white light goes from air into the water droplet at an incidence angle. The angle between the red (660 nm) and violet (410 nm) parts of the refracted light is 0.19°.
What is white light?The white light is the ray coming directly from the Sun. When it strikes any glass object, an spectrum of colors with different wavelength is formed.
Given is the angle of incidence, i = 36.2°, the refractive index of water for red light is 1.331 , the refractive index of water for violet light is 1.340 and refractive index of air is 1.
Using the Snell's law, the angle of refraction of red light will be
1.331 x sin r(R) = 1 x sin 36.2
r(R) = 26.342°
Using the Snell's law, the angle of refraction of violet light will be
1.340 x sin r(R) = 1 x sin 36.2
r (V) = 26.152°
Difference in the angle of refraction of red and violet light is
r(R) - r (V) = 26.342 - 26.152 = 0.19°
Thus, the angle between the red (660 nm) and violet (410 nm) parts of the refracted light is 0.19°.
