Answer:
Oxygen debt is a physiological phenomenon in which a person consume oxygen at fater rate that it replaced by new oxygen molecules.
As shown in the graph, oxygen debt occurs just after the end of exercise because oxygen is consumed at faster rate during exercise that leads to increased respiration and body attempts to replace the used oxygen.
To overcome the problem of oxygen debt, a person should take rest that allows the body to replenish its oxygen supply.

2. Which of the following statements is true of persuasive messages?
A. People tune out repetitious messages, so they quickly lose effectiveness.
B. Messages presenting a one-sided argument tend to be more effective than "he said; she said" messages.
C. Messages that offer a remedy for a person's fears tend to be effective.
D. An effective message will reach all audiences, regardless of background.
Answer:
C. Messages that offer a remedy for a person's fears tend to be effective.
Explanation:
The manner in which the message is presented. Presenting two sides of an argument makes the message seem more believable and persuasive than presenting just one side. Such an approach gives the message a sense of being impartial and factual. *Presenting a fear factor also may persuade people. For example, ads for different kinds of medicines present the dangers lurking around us as they offer a remedy.
Repetition. Repeated exposure to stimuli—like ads—is more likely to have favorable effects on attitudes than infrequent exposure. That’s why companies spend lots of money making sure their ads run again and again and why they have their logos and messages on race cars, buses, and billboards. The more often you see or hear a message, the more likely you are to have a positive attitude toward it.
Messages that offer a remedy for a person's fears tend to be effective is true for persuasive message. Therefore, option (C) is correct.
What is a persuasive message?To persuade someone means to move them emotionally or to motivate them to act in a certain way by presenting them with arguments that convince them to accept your viewpoint or act in the way you want them to. A persuasive message can be either spoken or written and is a form of communication that persuades the reader or listener to behave or act in a particular way.
The first step in convincing someone is to motivate them. If persuasion is a process, and the action of your audience (such as purchasing a product or service) is the goal, then motivating them to accept an argument or a series of positions leading to the decision that you want them to adopt is one way to help achieve that goal. If you want them to buy a product or service, for example, this would be an action.

During the process of translation in a eukaryote messenger RNA is spliced in the nucleus. amino acids are synthesized by RNA polymerase. transfer RNAs are joined together by a large enzyme complex. ribosomes must be imported into the nucleus. mRNA interacts with ribosomes in the cytoplasm.
Answer:
mRNA interacts with ribosomes in the cytoplasm.
Explanation:
The correct option would be that mRNA interacts with ribosomes in the cytoplasm.
Translation involves the use of genetic codes in mRNA to synthesize amino acids that are eventually linked together by polypeptide bonds to form proteins.
During translation, the mRNA synthesized in the nucleus is transported into the cytoplasm where it gets attached to the ribosome and another RNA - the tRNA. The codons on the mRNA eventually match with the anticodon of the tRNA with the later releasing the amino acid that corresponds to each codon.
Hence, the correct answer out of all the options is that mRNA interacts with ribosomes in the cytoplasm.

Rima eat guava explain how the teeth tongue and sliva will help to break it down
Answer:
Please find the role of teeth, tongue and saliva in digesting guava below
Explanation:
Digestion is generally the process of breaking down complex food substances into their simplest form. However, as easy as this sounds, there are series of processes that must take place in between to achieve the final result.
Once a food substance like guava enters the mouth (ingestion), it initially gets chewed by the TEETH in order to break it down to smaller masses that can be swallowed. During the process of chewing, the TONGUE helps to move the food around the mouth and later helps push it down the gullet/digestive tract. SALIVA, on the other hand, creates a moisturizing environment for the food to form a Bolus (round mass of food ready to pass down the esophagus). The saliva also contains an enzyme called AMYLASE that helps chemically degrade starch content of the food before passed through the digestive tract.

PLEASE ANSWER QUICKLY Which statement about cell theory is INCORRECT? New cells are spontaneously created from existing cells. All organisms are composed of one or more cells. Cells are the basic unit of life and structure. New cells are created from existing cells.
Answer:
New cells are spontaneously created from existing cells
Explanation:
In the 1830's, three scientists namely: Matthias Schleiden (a botanist), Theodor Schwann (a zoologist) and Rudolf Virchow proposed the Unified cell theory. In this theory, three parts were universally accepted and they are as follows:
1) Cells are the fundamental and basic unit of all life and structure.
2) All living organisms are made up of one or more of these cells.
3) New cells arise from already pre-existing cells.
These three parts are the widely accepted parts of the cell theory. Although, it was once believed that new cells arose from inorganic matter. This theory, called spontaneous generation or abiogenesis was later disapproved.
Therefore, the statement that, "new cells are spontaneously created from existing cells" is not a part of the CELL THEORY.
You are the lucky student of a wacky professor who develops a time machine. He asks if you will test it with him. You get in and there is an immediate glitch–the date readout fails so that when you land you are not sure what era you are in. As your time machine lands, you see an unusual landscape before you. As you open the door you realize you cannot breathe. You quickly shut the door, realizing you are in the _____.
1) Archaean eon
2) Cambrian period
3) Cenozoic era
4) Mesozoic era
Answer: Option 1 is the correct answer
Archaean eon
Explanation:
You are in the Archean Eon era because the it was early in the Archean that life first appeared on Earth. The most two earlier of the formal divisions of Precambrian time (about 4.6 billion to 541 million years ago) and the period when life first formed on Earth It began about 4 billion years ago with the formation of Earth’s crust and enlongated to the begining of the Proterozoic Eon 2.5 billion years ago; the latter is the second formal division of Precambrian time.
In the Archean eon there are unsual landscapes no rocks are preserved from this stage. The earliest terrestrial materials are not rocks but minerals.
Throughout the Archean, oceanic and island arc crust was produced semi-half way.
You cannot breathe because there was no oxygen on the Earth. Oxygen was only present in compounds such as water and chemical reactions change to carbon containing molecules that form simple living cells that does not require oxygen.

Answer:
i think it is the state park im not sure but lmk if im wrong or right
Explanation:
The correct answer is the plane, as it is flying in the sky, but the lava from the volcano after its eruption can easily flow down to the park, hospitals, etc., and the plane is least about to be affected by the volcanic eruption.
What is a volcanic eruption?A volcanic eruption is a natural phenomenon that occurs when magma, ash, and gases are expelled from a volcanic vent or fissure in the Earth's surface. Volcanic eruptions can range from relatively small and quiet to explosive and violent, and they can have significant impacts on the environment and on human populations. Volcanic ash and lava can be carried by the wind over large distances, so the direction of the wind and its strength are important factors in determining which areas will be most affected. Areas that are located upwind from the volcano are likely to be more affected by volcanic ash and lava than areas that are located downwind.
Hence, the correct answer is the plane, as it is flying in the sky, but the lava from the volcano after its eruption can easily flow down to the park, hospitals, etc.
