essay about circulatory system​

Answers

Answer 1

Answer:

The circulatory system is one of the most important systems in the human body. It consists of the heart and blood vessels. It is what makes the blood in our body go round. The blood carries oxygen, nutrients and hormones and takes them to where they are needed and removes the waste products like carbon dioxide.

The circulatory system nourishes every cell, tissue, organ and organ system in the body. There are approximately ten pints of blood constantly circulating through seventy- five- thousand miles of blood vessels. These blood vessels reach every cell in the human body. Once they reach the cells they deliver much needed oxygen and remove carbon dioxide and other…show more content…

Arteries have walls that are much more elastic than veins because they transport under high pressure. The arteries cause you to feel a pulse in your wrist because of the great force of the heart pumping new blood into them. All the blood in the arteries, except for the pulmonary arteries, is oxygenated. The arteries divide up into smaller vessels called arterioles so have more muscle fibres and less elastic tissue than the larger arteries which allows them to contract and make the vessels narrower to restrict the blood flow. The arterioles divide up even more to form a branching network of vessels passing between the cells of every living tissue. The final branches are the capillaries.

Six teachers sat down for lunch at the round table in the faculty room. Ms. Bailey sat between the science teacher and the math teacher. Mr. Vollert, the math teacher, sat between the music teacher and Ms. Bailey. The ELA teacher sat next to the science teacher. The science teacher sat between the Spanish teacher and Mrs. Strain. Mr. Holman isn't a writer. Mrs. Karels cannot carry a tune, but she sat between Ms. Merridy and Mrs. Strain, one of which is very musical.

Directions: Use the diagram to the right to figure out where each teacher sat at the faculty room table. Write their name and what subject they teach on the correct chair. Use the bottom of this page to brainstorm!

Answers

Answer:

Mis.Karels

Explanation:

Well I just read the problom a cople of times and I found the answer.

Answer:  
Ms. Bailey is the Spanish teacher.
Mr. Vollert is the Math teacher.
Ms. Merridy is the Music teacher.
Mr. Holman is the Science teacher.
Mrs. Strain is the ELA teacher.
Mrs. Karels has no specified subject.

The Seating Chart would look as such:
                        Mrs. Bailey (Spanish)
Mr. Vollert (Math)                             Mr. Holman (Science)
Ms. Merridy (Music)                         Mrs. Strain (ELA)
                        Mrs. Karels (No subject)

Explanation:

We are told from the very beginning that Mr. Vollert is the Math teacher. Therefore none of the other teachers can teach math. We know that Mrs. Bailey sits beside the science teacher and Mr. Vollert (Math). Mr. Vollert (Math) sits beside Mrs. Bailey and the music teacher. Therefore, Mrs. Bailey can be neither the music teacher nor the science teacher. The ELA teacher sits beside the Science teacher. The Science teacher sits between the Spanish teacher and Mrs. Strain. Meaning Mrs. Strain cannot be the Spanish teacher, so she has to be the ELA teacher. Mr. Holman isn't a writer, which means he doesn't teach ELA. Mrs. Karels cannot carry a tune, meaning she doesn't teach Music. Mrs. Karels sits between Ms. Merridy and Mrs. Strain (ELA), and one of them can carry a tune. That person has to be Ms. Merridy (Music) because Mrs. Strain already has a subject assigned to her. Now we have two teachers left, Mr. Holman and Mrs. Karels, one of which teaches Science and the other has an unspecified subject. Ms. Karels can't teach Science because the Science teacher sits between Mrs. Strain (ELA) and Mrs. Bailey (Spanish) and Ms. Karels sits between Mrs. Strain (ELA) and Ms. Merridy (Music), therefore the Science teacher is Mr. Holman (Science).

Miss Lottie’s house was the most ramshackle of all our ramshackle homes. The sun and rain had long since faded its rickety frame siding from white to a sullen gray. The boards themselves seemed to remain upright not from being nailed together but rather from leaning together, like a house that a child might have constructed from cards. A brisk wind might have blown it down, and the fact that it was still standing implied a kind of enchantment that was stronger than the elements. There it stood and as far as I know is standing yet—a gray, rotting thing with no porch, no shutters, no steps, set on a cramped lot with no grass, not even any weeds—a monument to decay.

What tone is implied by the narrator’s description in the passage above?

Answers

Answer:

D.Switches between first person and third person limited

Explanation:

To answer this question correctly, we need to understand the differences between the perspectives. The first person point of view has the characteristic that it only allows the reader to experience the action and thoughts of a character within a book, which means that the first person is limited in itself. Also, it is grammatically characterized by the use of the pronoun I. The third person, on the other hand, gives a more integral perception of the story, a fuller view, and it is grammatically characterized by the use of any other pronouns except I. However, while the simple third person is limited also to only the emotions, actions, thoughts and feelings of one character, the third person omniscient detaches the reader from a single character and allows him/her to have full view of all the characters, all the actions taken by all the characters and knows information that even the characters themselves might not know. The best way to know when a writer is using any of these perspectives, is by focusing on the pronouns being used. In this case, we have two instances. The use of the third person, because we have someone narrating the characteristics of the house of Miss Lottie, in comparisson with those of all others. It is also evident when the writer uses "our" that this person is part of the characters, so this person is narrating and also participating and whatever is happening is depending on this character´s narration. Then, after all the details, the narrator passes to the first person by saying: "There it stood and as far as I know is standing yet". This is why the correct answer is D. Switches between first person and third person limited.

C two brothers fight on opposite sides of a war
D lightning crashes. the scene fades to black​

Answers

Answer:

B

Explanation:

it's applicable to most people, it has some sort of moral, and its a storyline

The option is most clearly a theme is home is a place all people carry inside them. Thus the correct option is B.

What is a Theme?

The theme of a story highlights the storyline on which the story is based. These theme helps to determine the plot of the story as well as the events that are going to take place.

For example "An Uncomfortable Bed" highlights irony in the story that how a group of friends makes fun of each other in a humorous manner. In the story, the main character in order to avoid the joke ends in the worst situation.

The statement "a home is a place all people carry inside them" identifies a plot where people love each other based on respect, satisfaction, and adjustment there is no competition exist between family members.

Therefore, option B is appropriate.
