What is a scientific theory? What is a hypothesis? How are they similar? How do they differ?

Answers

Answer: Scientific theories can be backed up with evidence/data (the evidence that backs the theory isn't common knowledge to everyone yet), while a hypothesis is just an educated guess, meaning that you are making a prediction based on something already known.

They are both similar in the sense that they are questions that are answered by facts, but theories are answered with factual evidence rather than factual reasoning (hypothesis).

An 18-month-old boy was referred to the pediatrics clinic because of persistent anemia and associated failure to thrive. Laboratory analysis confirmed a microcytic anemia and revealed blood lead levels of 50 mg/dL (2 times normal levels) and high levels of coproporphyrinogen III in the urine. The child was put on chelation therapy and recovered uneventfully. The cause of the child's difficulty was most likely due to the effects of the lead. The findings in this patient most closely reflect lead inhibition of which of the following enzymes of heme biosynthesis?a) δ-aminolevulinic acid (ALA) dehydrataseb) ferrochelatasec) porphobilinogen (PBG) deaminased) proporphyrinogen III cosynthasee) uroporphyrinogen decarboxylase

Answers

Answer:

B) Ferrochelatase

Explanation:

The hematological effects of lead poisoning includes the inhibition of the body's ability to produce hemoglobin. This is done by interfering with several enzymatic steps in the heme synthesis pathway.

Lead inhibits or decreases heme synthesis by inhibiting Ferrochelatase enzyme activity.

Ferrochelatase catalyses the insertion of iron into protoporphyrin IX and is very sensitive to lead.

Earth is heated by global warming how Ian the water cycle affected global warming

The heat increases the rat of the water making it easier for the water to turn onto vapor

Explanation:

Answer:

[tex]\boxed{\mathrm{view \: explanation}}[/tex]

Explanation:

As the global temperatures increases, more evaporation and precipitation will be the result. Hence, speeding up the water cycle.

At higher temperatures, there is more evaporation from land and sea into the atmosphere. Since the air gets warmer, it can hold more water vapor, this can lead to high rainstorms or precipitation.

In CaF2, the oxidation number of Ca is , and that of F is . In H2SO4, the oxidation number of H is , that of S is , and that of O is . In CaSO4, the oxidation number of Ca is , that of S is , and that of O is . In HF, the oxidation number of H is , and that of F is

Answers

Answer:

1. The oxidation number of Ca is 2, F is -1 in CaF₂

2. The oxidation number of H is 2, S is 6, O is -8 in H₂SO₄

3. The oxidation number of Ca is 2, S is 6, O is -8 in CaSO₄

4. The oxidation number of H is 1, F is -1 in HF

Explanation:

To get the oxidation number, we need to take the oxidation number of the whole compound 0. Then we need to know the oxidation number of the other elements and we need to take 'x' as the oxidation number of the unknown element.

Example:

In case of CaSO₄,

We can write an equation as-

CaSO₄ = 0

If we need to know the oxidation number of S

We can write the equation like this-

→2+ x+ (-2*4) = 0 (as we know the oxidation number of Ca is 2 as it has two electrons in its last shell which it gives to other elements to form bonds and the oxidation number of O is -2 as it takes 2 electrons to complete its outer shell)

→2+ x+ (-8) = 0

→2+ x- 8 = 0

→x- 6 = 0

→x = 6; which is the oxidation number of S

                       

The following are the oxidation numbers:

In CaF2, the oxidation number of Ca is +2, and that of F is -1.

In H2SO4, the oxidation number of H is +1, that of S is +6, and that of O is -2.

In CaSO4, the oxidation number of Ca is +2, that of S is +6, and that of O is -2.

In HF, the oxidation number of H is +1, and that of F is -1.

What is oxidation number?

Oxidation numbers are a way of representing the degree of oxidation (loss of electrons) or reduction (gain of electrons) of an element in a chemical compound. The oxidation number of an element is calculated based on the number of valence electrons (electrons in the outermost energy level of an atom) and the rules for assigning oxidation numbers.

In general, the oxidation number of an element is equal to the charge it would have if all the bonds in the compound were ionic (made up of positive and negative ions). This allows chemists to predict the behavior of elements in a compound and to balance chemical equations.

What is seismic wave?

They are commonly employed in non-destructive testing to find flaws and can be created in materials in a variety of methods, as by a localized impact or by piezoelectric transduction.

These include what are known as Rayleigh waves. A Rayleigh wave's amplitude decreases with depth below the surface and becomes noticeably tiny at depths greater than a few wavelengths.

As a result, the disturbance is limited to a solid's surface layers. The motion experienced by the surface layers includes both transverse and longitudinal components.

Therefore, Rayleigh wave type of seismic wave is highlighted in the image.

"(Other players) don't want to hurt me," he said. "I try to juke them." His coach said opponents soon learn to play him honestly or pay the consequences

Answers

Complete question reads;

Read the following paragraph from the article.

In soccer, Hai is a goal scorer who plays in forward positions, always keeping his eyes trained on the ball and chance to put one past a goalkeeper. He’s not above playing advantages. “(Other players) don’t want to hurt me,” he said. “I try to juke them.” His coach said opponents soon learn to play him honestly or pay the consequences.

Which idea is BEST supported by the above paragraph?

(A) Hai's coach recognizes that Hai needs to be protected from bullying.

(B) Hai is a very skilled soccer player who consistently outdoes his peers.

(C) Hai's coach wants Hai to understand that it is not acceptable to cheat to win a soccer game.

(D) Hai is sometimes underestimated by other players, and he uses this to his advantage.

Answer:

(C) Hai's coach wants Hai to understand that it is not acceptable to cheat to win asoccer game.

Explanation:

The expression, "pay the consequences" as used by Hai's coach indicates  his intention of letting Hai know the rules governing soccer; meaning there's a penalty when opponents hurt a rival player.

Interestingly, in the game of soccer, it is a foul to deliberately bring down your opponent. Major consequences arrive when a player receives a red card from the referee, due to an offense committed by the player; the red card indicates that the player would be sent out of the court.

Mr. B has been transferred to your floor to wait and see whether the chest tube allows his lungs to completely re-expand. But when he arrives, he is in severe respiratory distress. He says "I felt better before I came into the ER! Is this tube doing anything

Answers

The question is incomplete,below is the complete question.

Mr. B has been transferred to your floor to wait and see whether the chest tube allows his lungs to completely re-expand. But when he arrives, he is in severe respiratory distress. He says "I felt better before I came into the ER! Is this tube doing anything?"

You tell the Clinical Nurse Specialist (CNS). As the two of you move him into the bed, you notice that his chest tube bottle is lying on its side on the gurney, with air going into it. When you point this out to the CNS, she immediately grabs the bottle and sets it upright on the floor. You see air start bubbling through the fluid right away. "That was the problem!" she says. "They lost the water seal, and air was going into his chest from the bottle. You would not believe how many times that happens on transport." When you examine Mr. B, you have trouble detecting his lung sounds on the left. Even stranger, his apical heart sound is in the wrong place - it is over toward the right side of his chest. His respiration rate and heart rate are both increased, and he is struggling to breathe. "Let's give him a little oxygen. He'll be a lot better in a half-hour," says the CNS. "Check back on him."

QUESTION - Why would accumulation of air in his pleural space cause his heart sounds to be in the wrong place?

Accumulation of air in Mr B pleural space will cause his heart sound to be heard in the wrong place because the left side is his chest is being filled up with air making the organs in his chest to to be pushed over to the right side.

Born on August 26, 1918 in West Virginia, Johnson had a gift for numbers. As Johnson later described, she spent her life countingcounting the steps she walked, the dishes she washed. Anything that could be counted, I did, she once said. School came easily for Johnson, and she completed eighth grade by the age of 10. After that, she couldnt continue learning locally because her county denied African American students access to secondary education. Johnsons father, Joshua, moved the family 120 miles away so she could attend high school. By 18, she graduated with honors from West Virginia State College, receiving degrees in mathematics and French. She then went on to teach these subjects at a public school. After teaching for many years, one job posting changed the arc of her life. The National Advisory Committee for Aeronautics (NACA) was looking to hire women to fill unique positions. The job title: Computer. Based at Langley Research Center, these human calculators checked the math done by NACAs male engineers and mathematicians. Johnsons sharp intellect and resourcefulness were quickly recognized at Langley; she was promoted after only two weeks. Nonetheless, Johnson faced barriers at the agency. At the time, many workplaces werent integrated, and Johnson and her African American colleagues were segregated within an area of Langley named West Computers. Regardless, she steadfastly asked questions and made her voice heard. In 1958, NACA began to focus more on space travel, and the agency was newly dubbed the National Aeronautics and Space Administration (NASA). Johnsons career flourished at NASA. In 1961, Johnson plotted astronaut Alan Shepards path into space. Then in 1962, Johnson helped astronaut John Glenn to be the first American to orbit the Earth. Even though NASA had started using electronic computers, Johnson was the one to double-check the machines calculations before blast-off. Additionally, Johnson contributed to Apollo 11s milestone 1969 moon landing. She also helped Apollo 13 return safely home after an equipment malfunction. Later in her career, Johnson worked on calculations for NASAs space shuttles and satellites. Even with such stellar contributions, many people in America didnt know Johnsons name until long after her retirement. In 2016, writer Margot Lee Shetterly published Hidden Figures, a chronicle of Johnson and two of her fellow mathematicians work at NASA.

At December 31, 2016, the client had a receivable of $820,000 from Hendricks Inc. on its balance sheet. Hendricks Inc. has gone bankrupt, and no recovery is expected. The client proposes to write off the receivable as a prior period item.2. The client proposes the following changes in depreciation policies.(a) For office furniture and fixtures, it proposes to change from a 10-year useful life to an 8-year life. If this change had been made in prior years, retained earnings at December 31, 2016, would have been $250,000 less. The effect of the change on 2017 income alone is a reduction of $60,000.(b) For its new equipment in the leasing division, the client proposes to adopt the sum-of-the-years'-digits depreciation method. The client had never used SYD before. The first year the client operated a leasing division was 2017. If straight-line depreciation were used, 2017 income would be $110,000 greater.3.In preparing its 2016 statements, one of the client's bookkeepers overstated ending inventory by $235,000 because of a mathematical error. The client proposes to treat this item as a prior period adjustment.4. In the past, the client has spread preproduction costs in its furniture division over 5 years. Because its latest furniture is of the "fad" type, it appears that the largest volume of sales will occur during the first 2 years after introduction. Consequently, the client proposes to amortize preproduction costs on a per-unit basis, which will result in expensing most of such costs during the first 2 years after the furniture's introduction. If the new accounting method had been used prior to 2017, retained earnings at December 31, 2016, would have been $375,000 less.5. For the nursery division, the client proposes to switch from FIFO to LIFO inventories because it believes that LIFO will provide a better matching of current costs with revenues. The effect of making this change on 2017 earnings will be an increase of $320,000. The client says that the effect of the change on December 31, 2016, retained earnings cannot be determined.6. To achieve an appropriate recognition of revenues and expenses in its building construction division, the client proposes to switch from the completed-contract method of accounting to the percentage-of-completion method. Had the percentage-of-completion method been employed in all prior years, retained earnings at December 31, 2016, would have been $1,075,000 greater.Instructions(a) For each of the changes described above, decide whether:(1) The change involves an accounting principle, accounting estimate, or correction of an error.(2) Restatement of opening retained earnings is required.(b) What would be the proper adjustment to the December 31, 2016, retained earnings?
