Answer:
Neutral
Explanation:
The charge of an oxygen atom is neutral.
The charge should be positive.
The following information should be considered;
In the case when an atom had 8 protons and 8 electrons i.e. oxygen knocking one of the electrons out, makes 8 protons and 7 electrons.The atom now has a net charge of +1 because the 7 electrons cancel the positive charges of 7 of the protons in the nucleus, but there is one remaining proton with a positive charge.Learn more: https://brainly.com/question/10283285?referrer=searchResults
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.
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.

(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
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.

What are the types of chemical bond ?The force of attraction between different constituents like atoms, ions which hold them together is called as chemical bonding.
Different types of bonds formed either from the loss or gain or sharing of electrons between two atoms/molecules.
Ionic bonding in which transfer of electrons from one atom or molecule to another there by generation of opposite charges on individual atoms.
The organic compound exhibit covalent bond that is sharing of electrons between atoms. it can be either polar or non-polar in nature.
Polar covalent chemical bond refers to unequal sharing of electrons between more and less electronegative atom. Water is the best example.

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?
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.

Thinking back to yesterday's reading, what type of ecological relationship is it? What are the bacteria doing for us? How do they avoid being killed off by our immune system? Gut Bacteria Reading
Answer:
The relationship between gut bacteria and we the host is a mutualistic relationship. This is a form of relationship where both we and the bacteria benefit from the bacteria living in our gut.
They help us in our digestion process to break down some food particles into their basic units, some of which we would not be able to do without them. They also help to keep the gut’s surface intact, provide vitamins, and fight off other harmful bacteria.
Bacteria use immunity genes to neutralize toxins and protect themselves against been destroyed by our immune system by copying our immune resistance code, and using this code to make their outer membrane.

Explanation:
The unified cell theory was proposed by three scientists in the 1830's, they are: Mathias Scleiden, Theodor Schwann and Rudolf Virchow. They proposed three components that makes up the widely accepted cell theory. The components are:
1) Cell is the basic and fundamental unit of all living things
2) All living organisms are composed of one or more cells.
3) Cells arise from already existing cells
Based on these components of the cell theory, a STRAWBERRY is the household item that would be composed of cells because it is the only living thing (plant) in the option.
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?
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.
