If I am correct it should be nucleons
The collection of protons and neutrons in the center of the atom is called the nucleus.
Question 1 is true because it was called Pangea
Question 2 is false because it had a lot of impact on the distribution of species, before the moving continents animals could roam where ever they want but after the splitting of the continents the species were stuck in one place because water separated other continents and land species cant swim.
The muscles of the body are part of the musculoskeletal system but would not operate without the nervous system providing the impulses that cause the muscles to act. Correct answer: C The nervous system controls all activities within the human body, including the muscles. It sends messages between the brain and the muscles very quickly using nerve impulses (action potentials).
Nervous is the system that provides impulse
Answer:the reaction arrow is used most frequently and indicates a reaction occurring from the reactants to the products. The arrow's head points in the direction the reaction proceeds in.
such as platinum and palladium, can greatly
increase the rate of this reaction. During this
process, the gaseous reactants are pumped
across a layer of metal powder. An example of this
process is shown below.
Describe how the metal probably increases the
reaction rate, identify whether this is an example of
homogeneous or heterogeneous catalysis, and
explain how you know.
A reducible molecule undergoes hydrogenation when hydrogen is added to it. Alkenes, alkynes, and aromatic molecules that are unsaturated are converted into saturated products through the hydrogenation of hydrocarbons.
A chemical reaction known as hydrogenation occurs when molecular hydrogen interacts with another substance or element, typically in the presence of a catalyst made of nickel, palladium, or platinum. The method is frequently used to saturate or decrease organic molecules.
With the aid of nickel or palladium catalysts, unsaturated hydrocarbons are added to hydrogen in this process to create saturated hydrocarbons. Example: Applying an addition reaction to ethane in the presence of catalysts like nickel or palladium allows for the conversion of ethane.
When making plastics, unsaturated hydrocarbons are incredibly helpful organic substances. Egg cartons, disposable cups, and other practical things are made of polystyrene. Alkenes are utilized in the production of industrial compounds like alcohol.
Thus, A reducible molecule undergoes hydrogenation when hydrogen is added to it.

Answer: The metal probably increases reaction rate by either holding reactant molecules in the correct orientation to react or by weakening or breaking bonds in reactant molecules to make them more reactive. This is an example of heterogeneous catalysis.
Explanation: It is heterogeneous catalysis because the catalyst is a solid and the reactants are gases. In heterogeneous catalysis, the catalyst is in a different phase than the reactants.
We have that When a carbon atom losses a proton Boron element would be formed.
Boron element
From the question we are told
Is a carbon atom spontaneously lost a proton what element would be formed
Generally
Carbon as an element has an atomic number of 6
Therefore
When a carbon atom losses a proton Boron element would be formed.

Answer: Protons carry a positive electrical charge and they alone determine the charge of the nucleus. Adding or removing protons from the nucleus changes the charge of the nucleus and changes that atom's atomic number. So, adding or removing protons from the nucleus changes what element that atom is!
Explanation: For example, adding a proton to the nucleus of an atom of hydrogen creates an atom of helium. (Actually, a few neutrons have to be added as well to make the new nucleus stable, but the end result is still helium.) Keep in mind that atoms, by definition, are electrically neutral and always contain the same number of protons and electrons.
