Answer:

Explanation:

This question seeks to classify the statements made into Theory, Hypothesis, law or fact.

An hypothesis is a scientific guess which when experimented is conducted, a theory is carefully proposed to explain this experiment and the conclusions thereof. And a law is a certain description (usually proposed by an individual or group of individuals) of a particular phenomenon that must undergone a certain level of scientific inquiry. A fact is however a truthful statement of assertion that could be easily verifiable.

(2) Water freezes at 32° F

Fact (because water freezes at 0°C which is same as 32° F and be easily verified)

(3) The solar system formed from a disk of spinning disk of gas and dust

Theory (This is one of the theories that suggests the formation of the solar system)

(4) F = ma meaning Force = mass × acceleration

Law (This is a mathematical representation of the Newton's second law of motion)

(5) The Universe is expanding

Theory (This is the cosmological theory proposed by Edwin Hubble using the relationship between the speeds of distant galaxies and their respective distances from Earth)

(6) Newton's Laws of Motion explain why orbits are ellipses

Fact (because the Newton's laws of motion indeed provided explanation about the earth's movement around the sun which shows/describes how earth is being pulled into an elliptical orbit)

(7) The Universe was created at an event known as the Big Bang

Theory (This is popularly known as the Big Bang Theory)

(8) More babies are born at the full moon

Hypothesis (This is just a guess and still requires a scientific experiment to back it up)

(9) Matter is composed (made up of) atoms

Theory (This is one of the postulates of the Dalton's atomic theory)

(10) Sections of the earth's crust move around over the mantle as a result of convection

Fact (This is known as mantle convection)

(11) Darwin explained how life on Earth evolved over time by examining the fossil record

Theory (This statement describes what is known as the Darwin's theory of evolution)

pancreatitis is an acute inflammation of the pancreas, caused by the premature activation of digestive enzymes that then digest

AnnyKZ [126]

According to the given statement lysosomes enzymes are often found in which part of the cell.

<h3>What is the main cause of pancreatitis?</h3>

Pancreatitis symptoms include the redness and inflammation of the pancreas. It could be chronic or acutely sudden (chronic). The two most frequent reasons are drinking alcohol and solid masses in the gallbladder (which can vary over time). The main objectives of treatment are to rest the pancreas and let it heal.

<h3>What treatment for pancreatitis works the quickest?</h3>

Mild acute pancreatitis will develop in a few days with rest and medicine. When your pancreatitis is more severe, you might also try the following additional treatments: Surgery. Your doctor can suggest cholecystectomy procedures to remove the gallbladder if stones are the source of your pancreatitis.

What do you think would happen to a protein if it were a different shape?

Fofino [41]

Answer:

Well protines come in diffrent shapes, for there diffrent functions. The first level, or primary structure, is the linear sequence of amino acids that creates the peptide chain. In the secondary structure, hydrogen bonding between different amino acids creates a three-dimensional geometry like an alpha helix or pleated sheet. An alpha helix is simply a spiral or coiled molecule, whereas a pleated sheet looks like a ribbon with regular peaks and valleys as part of the fabric. The tertiary structure describes the overall shape of the protein. Most tertiary structures are either globular or fibrous. Generally, nonstructural proteins such as enzymes are globular, which means they look spherical. The enzyme amylase is a good example of a globular protein. Structural proteins are typically long and thin, and hence the name, fibrous. Quaternary structures describe the protein's appearance when a protein is composed of two or more polypeptide chains. Often the polypeptide chains will hydrogen bond with each other in unique patterns to create the desired protein configuration.

some hormones are proteins; and some proteins are involved with digestion, respiration, reproduction, and even normal vision, just to mention a few.

f the three-dimensional structure of the protein is altered because of a change in the structure of the amino acids, the protein becomes denatured and does not perform its function as expected.

The contraction of the diaphragm and intercostal muscles begins inspiration explain exactly what happens, in terms of volume and

jasenka [17]

<span>The contraction of the diaphragm causes an increase in the height of the thoracic cavity. Contraction of the intercostal muscles causes the diameter of the thoracic cavity to increase. The increased thoracic cavity volume brings a volume increase in intrapulmonary volume, which causes a drop in pressure relative to atmospheric pressure. Air rushes into lungs along this pressure gradient until intrapulmonary and atmospheric pressure are equal.</span>
