Answer:
The most common type of bond formed by carbon is a covalent bond in which carbon shares electrons with other atoms. There are three major types of covalent bonds: single, double, and triple bonds. A carbon atom itself can form four single bonds. Since carbon has four valence electrons, it forms covalent bonds with four neighboring carbon atoms.
Explanation:
Carbon most often forms a covalent bond with other atoms. If the bond is with another carbon atom, it is a pure covalent (or nonpolar covalent) bond. If it is with another atom, a polar covalent bond is formed.
The most common oxidation state of carbon is +4 or -4.
Less commonly, carbon forms ionic bonds with other atoms. This occurs when there is a large electronegativity difference between carbon and the other atom.
So, it usually forms covalent bonds. So D.

(03.03 MC)What happens when a sound wave moves from air to water?
It slows down
It speeds up
It stays the same.
It reverses
Answers
Answer:
It slows down
Explanation:
Because water is denser than air the sound waves move through it faster which means that if the sound wave is coming from the water to the air then it will slow down. Also i took the test and got it right.
When a sound wave moves from air to water It slows down.
What is sound wave?Sound is a mechanical wave that travels across a medium by means of the back and forth vibrating of its constituent particles. When a sound wave travels through air from left to right, the energy of the sound wave will cause displacement of air molecules in both the right and left directions.
The direction of the energy flow is parallel (and anti-parallel) to the particle motion. Sound waves in the air are described as longitudinal waves because of this.
Therefore, When a sound wave moves from air to water It slows down.

The body monitors the levels of oxygen in the blood to regulate breathing. Isabel is running in a marathon and is near the finish line. She feels out of breath. How will her nervous system work to generate a reaction?
Answers
Answer:
Low oxygen pressures in the blood cause the nervous system to respond with hyperventilation.
Explanation:
In our body, the partial pressures of oxygen in the blood is a marker of blood pressure and hyperventilation.
The partial pressure of this gas may be decreasing due to lack of partial pressure of oxygen in the atmosphere that we breathe or in the great respiratory demands, that is why in this case, the partial pressures of oxygen during the marathon decrease.
When decreasing, this is captured by the nervous receptors and the CNS executes an increase in respiratory rate, generating hyperventilation so that the partial pressure of oxygen increases.
These receptors are chemoreceptors, capable of detecting the slight drop in blood pH due to oxygen deficiency associated with hemoglobin, since metabolic acidity is very common in cases of low oxygenation.

Juan has been diagnosed with mono, and the doctor wants to determine if his spleen is enlarged. Where (quadrant, etc.) will the doctor palpate Juan's abdomen? What other organs might be compressed by Juan's enlarged spleen? Given the diagnosis, why is Juan's spleen enlarged and not his stomach or kidney?
Answers
Answer and Explanation:
Where (quadrant, etc.) will the doctor palpate Juan's abdomen?Under normal conditions in general the spleen can not be palped because of its reduced size. But when it is enlarged it might be easily touched. The spleen is located under the thoracic cage (rib cage) on the left side, between the 8th and 11th ribs. This would correspond to the left superior quadrant (left hemi-belly).
What other organs might be compressed by Juan's enlarged spleen?The enlargement of the spleen and the liver inflammation are symptoms of the mono disease. This enlargement might affect some neighboring organs such as the stomach, which might be displaced and compressed.
why is Juan's spleen enlarged and not his stomach or kidney?The spleen is part of the immunological system and helps the body to fight infections and filter old bloody cells taking them out of the blood current. This organ might get enlarged because blood cells accumulate in its interior. Red blood cells are excessively stored in the spleen, resulting in anemia. The more cells the spleen retains, the larger it becomes, and hence, the more blood cells it retains and destroys. If the spleen is unproperly working, it kills too many red blood cells and accumulates many others.
The Stomach and kidney are not part of the immunity system and they do not filter blood cells, so they do not seem to be affected by their accumulation.

A cell can be compared to a business. The Nucleus controls all cellular functions like a Chief Executive Officer that controls all of the operations and decisions of the business. Within the business there is the cytoplasm. The Cytoplasm in a cell, harbors cell organelles and provides structure. This compares to the factory work space that contains all the working bio-machinery and the nutrients, like the raw materials, for the cellular processes. The Cytoskeleton for a cell is what provides the shape and structure to the cell. This is compared to the architecture structure of a factory. It helps to support and strengthen the structure of the building. The Endoplasmic Reticulum of a cell is the site for protein synthesis, the vesicle packaging and transport. This is compared to an assembly line of the business. This is the main work space for production of the important cell components, for example the proteins. The Golgi Apparatus of the cell is the packaging of molecules into the transport vesicles. This is compared to the packaging department of a business. The packing department is the department that packages the goods that have been prepared. The Lysosomes of the cell is actually the membrane-bound cell organelle. It contains the digestive enzymes that break down the excess or the otherwise known worn-out parts of the cell. If the cell is considered damaged beyond repair it will help it to self-destruct with a process that is called programmed cell death. This is compared to the maintenance department of a business. The maintenance department is called in when there is old worn out machinery that needs replaced and discarded. The Mitochondria of the cell is in charge of producing the energy through cellular respiration. This is compared to the power plant or the generator of the business to help the production of energy. There are a few extra parts of the cell that could not be put on the chart above. The Plasma membrane of the cell is the semi permeable that controls cellular transport. This is compared to the Logistics department of the business. This department is in control of what is shipped in and out of the business. The last one is the Ribosomes of the cell. This Ribosomes are like the protein builders or the protein synthesizers of the cell. This is compared to the factory workers of the business. The works build the products for the company.

What is the difference between inorganic and organic compounds? A. Organic compounds are beneficial to the environment and inorganic compounds are not. B. Organic compounds contain carbon and inorganic compounds do not. C. Organic compounds contain ionic bonds and inorganic compounds contain covalent bonds. D. Organic compounds are produced naturally and inorganic compounds are human-made.
Answers
Answer: B would be the best answer
Explanation: The primary difference that lies between these organic compounds and inorganic compounds is that organic compounds always have a carbon atom while most of the inorganic compounds do not contain the carbon atom in them. Almost all the organic compounds contain the carbon-hydrogen or a simple C-H bond in them.
Option B is the right answer.
Organic compounds contain carbon and inorganic compounds do not.
Organic compounds contain one or more carbon atoms covalently linked to atoms of other elements, most commonly hydrogen, oxygen, or nitrogen. Carbides, carbonates, and cyanides are among the few carbon-containing compounds that are not classified as organic.
Organic compounds have covalently bound carbon, hydrogen, and frequently other elements. In chemistry, an inorganic compound lacks carbon-hydrogen bonds, i.e. is not an organic compound. Inorganic chemistry is a discipline of chemistry that studies inorganic compounds.
The most obvious difference between organic and inorganic substances is that organic compounds are primarily the outcome of the activity of a living being. In contrast, inorganic chemicals are obtained through natural processes unrelated to any of the Earth's life forms.
