do oxygen atoms become more stable or less stable when oxygen forms compounds. Explain.
Answer:
Do oxygen atoms become more stable or less stable when oxygen forms compounds? They become more stable because they gain or share valence electrons giving each oxygen atom a set of 8 valence electrons. They change because the number of valence electrons changes in a pattern that repeats in each period.

Which best explains how nutrients, salt, sediment and pollutants get into estuaries and oceans?
Answer:
There's not a "best" explanation unless it is a multiple choice question -
However, some prominent ways are
1) runoff from heavy rainfall
2) industrial discharge
3) storm drains
4) natural sediment transport via water flow / currents
Sediments, fertilizers, and other contaminants are transported to estuaries by water that drains from uplands. A large portion of the silt and contaminants are filtered out of the water as it passes through wetlands like swamps and salt marshes.
What are estuaries?A coastal body of saltwater that is partially contained, has one or more rivers or river or lake into it, and has a direct connection to the open sea is called an estuary. Estuaries are an instance of an ecotone since they are a zone of transition between river ecosystems and ocean settings.
A place in which a freshwater river or stream joins the ocean is called an estuary. In estuaries, brackish water is created when a freshwater river and the salty ocean mingle. Although not as salty as the ocean, brackish water has some saltiness. Water that descends from uplands carries contaminants including fertilisers, sediments, and more to estuaries.
Therefore, sediments, fertilizers, and other contaminants are transported to estuaries by water that drains from uplands.

Axillary bone is a term which belongs in a different group as all the other bones are present in lower portion of the body.
What are bones?The human skeleton of an adult consists of around 206 bones, depending on the counting of sternum .It is composed of 270 bones at the time of birth,but later decreases to 206, 80 bones in the axial skeleton and 126 bones in the appendicular skeleton. Many small accessory bones, such as sesamoid bones, are not included in this count.
The axial skeleton, comprising the spine, chest and head, contains 80 bones. The appendicular skeleton, comprising the arms and legs, including the shoulder and pelvic girdles, contains 126 bones, bringing the total for the entire skeleton to 206 bones. Infants are born with about 300 bones with most of it being cartilage, but will later fuse together and decrease over time to 206 bones.

Which healthcare professional requires the most years of education prior to working?
1. colorectal surgeon
2. gastroenterologist
3. orthodontist
4. endoscopy technician
Answer:
1. colorectal surgeon
Explanation:
Not 100% sure, but they are surgeons, which means they will need more time than just technicians and probably more time than other kinds of doctors in order to get the hang of surgery.
Colorectal surgeon requires the most years of education prior to working.
What is the most common complication of colorectal surgery?The most common complications following colorectal resection are infectious, wound infection or organ space infection, and gastrointestinal (GI) motility complications, including ileus and bowel obstruction.
Colon and rectal surgeries are typically performed to treat colon and rectal cancers, inflammatory bowel disease (IBD), or diverticulitis, and may also be necessary following an injury or wound, serious infection, or bowel blockage.
Colorectal surgery is a major surgical procedure. Prior to surgery, you will undergo a number of tests and scans, and your medications may change. You will also need to prepare your bowels by taking laxatives to clear your intestines before surgery.

If the man did not eat during the bike ride, why do you think that his blood glucose
level never went below 4.5 mml/L
Answer:
Due to less conversion of glucose into energy.
Explanation:
If the man did not eat during the bike ride, his blood glucose level never went below because there is very little amount energy is used. If a person perform activities such as running and exercise etc, it requires more energy and for that more glucose is converted into energy and glucose level went down while on the bike ride very little amount of energy is needed and for that very little amount of glucose is converted into energy and the glucose level did not went below 4.5 mml/L.

Imagine a science fiction movie in which a scientist creates a new species of organism. The scientist generates a whole population of the organism entirely through cloning of the males and females and then leaves them on an island. Explain why the population of clones would struggle to evolve if there was a major environmental change on the island.
The population of clones that struggle to evolve if there was a major environmental change on the island is :
-Lack of variations in the population as the clones are products of without fusion reproduction.
"Environmental change"The population of clones will struggle due to lack of variations in the population as the clones are products of without fusion reproduction.
Without fusion reproduction will allow the parent organism to produce offspring that are exactly identical to the parent.
Also it will help in production of large number of progenies at a single time.
Therefore, the population of clones will struggle due to lack of variations in the population as the clones are products of without fusion reproduction.

Passive transport is a movement of ions and other atomic or molecular substances across cell membranes without need of energy input. Unlike active transport, it does not require an input of cellular energy because it is instead driven by the tendency of the system to grow in entropy.
Is human survival independent of other species?
Explanation:
As far as I can think of, we're dependent on other species. If we can't be carnivores, then literally, the only other option I can think of is being a herbivore, and that still an organism. We need sufficient life essence to keep living. We CANNOT live without harming another organism.
In short of my babbling, human survival is not independent of other species.

All chemical equations must be balanced. This means that the same number of atoms
of each of the elements must be found in both the reactants and the products of the reaction. Which scientific law does this illustrate?
Law of Reflection
Law of Conservation of Energy
Law of Conservation of Mass
Law of Superposition
Answer:
The Law of Conservation of Mass.
Explanation:
The reasoning behind this is that when the chemical equation is balanced, so is the amount of mass. We make sure that the chemical equation is balanced to ensure that the law of conservation of mass is conserved. This is why we add coefficients to the beginning of reactants and products to make sure that the mass of the reactants combined is the same amount of mass of the products combined.

The Law of Conservation of Mass!
