Answer:
Once an enzymatic reaction is completed, the enzyme releases substrates.
Explanation:
The enzyme will always return to its original state at the completion of the reaction. One of the important properties of enzymes is that they remain ultimately unchanged by the reactions they catalyze. After an enzyme is done catalyzing a reaction, it releases its products (substrates).

According to scientific thought, what is a theory? O a a confirmed hypothesis O an unsubstantiated idea an interpretation supported by facts O a controversial guess
Answer:
- an interpretation supported by facts.
Explanation:
A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment. Such fact-supported theories are not "guesses" but reliable accounts of the real world.

Why does silicone dioxide have a higher melting point than sodium chloride?
[tex]\color{Black}\huge{Answer} [/tex]
It has a very high melting point as the ionic bond is very strong between them. More force is required to break down. Silicon dioxide is a giant covalent structure. It also has the highest melting point because the covalent bonds between them is the strongest.a boiling pot of soup with a lid on it to keep in the energy is what type of system?
Answer:
Closed system. :)
Explanation:
When the lid on the pot of soup is closed, it means matter can no longer escape, which in turn, makes it a closed system. I hope this helps, please let me know if you have any further questions

What does a flat, horizontal line mean on a
DISTANCE-time graph?
Speeding up
Travelling at a constant speed
Not moving (motionless, stationary)
Answer:
Explanation:
A straight horizontal line on a speed-time graph means that speed is constant. It is not changing over time. A straight line does not mean that the object is not moving!
Are two atoms of the same element identical?
Answer
Two atoms of the same chemical element are typically not identical. ... Two atoms of the same element can be different if their electrons are in different states. If one copper atom has an electron in an excited state and another copper atom has all of its electrons in the ground state, then the two atoms are differenter:

what phenomenon is the basis behind the ability to separate miscible liquids by distillation?
Answer:
The basis of the separation by steam distillation is that while the water and organic condensed phases are immiscible, the vapors of both are miscible. Once condensed, the two separate again allowing for an easy separation. As noted above, both liquids and solids can be distilled by steam.

answer for c plsssssss
Answer:
D has 18 electrons (since atomic number = protons = electrons)
[Ne]3s² 3p⁶ (spdf electron configuration)2, 8, 8 (basic electron configuration) ArgonE has 20 electrons
[Ar]4s² (spdf electron configuration)2, 8, 8, 2 (basic electron configuration)CalciumExplanation:
In spdf form, we are basically spreading out the total number of electrons over the different spdf orbitals. While doing this we have to remember that an s-orbital holds 2 electrons max, a p-orbital holds 6 electrons max, a d-orbital holds 10 electrons max, and an f-orbital holds 14 electrons max.
Based on energy levels, the orbitals are filled in the following order:
1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, and 7p
So for example Argon with 18 electrons would be filled in the following way:
1s², 2s², 2p⁶, 3s², 3p⁶.
This can be abbreviated using the configuration of the previous Noble gas for example [Ne] = 1s², 2s², 2p⁶
∴ we can express Argon as [Ne] 3s², 3p⁶.

how organ systems work?
Answer: Just as the organs in an organ system work together to accomplish their task, so the different organ systems also cooperate to keep the body running. For example, the respiratory system and the circulatory system work closely together to deliver oxygen to cells and to get rid of the carbon dioxide the cells produce.

Explain how CMB is observed on the Earth?
Answer:
the speed of light (all photons, naturally including those from the CMB, travel at the speed of light relative to you, regardless of frame or your velocity).
But I suspect you’ve asked this question because of a totally understandable but not quite correct set of assumptions about the universe. If my hunch is correct, you understand the CMB a bit like the skin of a balloon, gradually expanding over time. The Earth is a point somewhere in this balloon, and you’re asking about the Earth’s velocity relative to perhaps the center of this balloon. But that’s not quite how the universe works. It’s far more strange.
Our best hypothesis thus far is that the Big Bang happened from a single point. The “space” around us IS that single point. There is no origin point, since everywhere is by definition the origin point. You can see this for yourself by noticing that basically every star and galaxy we can see is - in the long run - moving away from us. And this is true regardless of whether you are on Earth or another star, or any point in the universe. So from this, it doesn’t really make sense to ask what the velocity of the earth is relative to the CMB rest frame, because space itself is expanding. Hopefully haven’t caused too many headaches!

viết các PTHH sau CuO + h20
Answer:
An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species. In redox reaction the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron.
In the reaction : CuO+H
2
⟶Cu+H 2 O
n the reaction H2
is oxidized since it has lost electrons and Cu is reduced since it has gained electrons.
