Answer:
brain
Explanation:
The central nervous system (CNS) controls most functions of the body and mind. It consists of two parts: the brain and the spinal cord. The brain is the center of our thoughts, the interpreter of our external environment, and the origin of control over body movement.
Answer:
OC brain, due to the brain being basically the smarts of your body, combined with it also managing, important functions of the body

What angle do parallel lines form when they intersect?
Answer:When two lines are cut by a transversal, the pairs of angles on one side of the transversal and inside the two lines are called the consecutive interior angles . If two parallel lines are cut by a transversal, then the pairs of consecutive interior angles formed are supplementary
Explanation:
Why is graphite used for electrodes?
Answer:
Graphite is an electrical conductor, hence useful in such applications as arc lamp electrodes. It can conduct electricity due to the vast electron delocalization within the carbon layers (a phenomenon called aromaticity). These valence electrons are free to move, so are able to conduct electricity.
Explanation:
Graphite is used for electrodes because
The atomic structure of graphite results in a large number of electrons not being bonded, allowing them to migrate between the layers of graphite. It is this large number of free electrons (electron delocalization) that give graphite its excellent conductive properties. As well as being a good conductor, graphite is also cheap, robust and easily accessible.

How many formula units of magnesium hydroxide are found in 10.88 moles?
Answer:
10.88 moles of magnesium hydroxide contain 65.52 ×10²³formula units
Explanation:
Given data:
Number of formula units of magnesium hydroxide = ?
Number of moles = 10.88 mol
Solution:
The given problem will be solve by using Avogadro number.
The number 6.022×10²³ is called Avogadro number.
1 mole contain 6.022×10²³ formula units.
10.88 mol × 6.022×10²³formula units /1 mol
65.52 ×10²³formula units
Thus, 10.88 moles of magnesium hydroxide contain 65.52 ×10²³formula units .

What is plate tectonics
Answer:
Plate tectonics is a scientific theory describing the large-scale motion of seven large plates and the movements of a larger number of smaller plates of Earth's lithosphere, since tectonic processes began on Earth between 3.3 and 3.5 billion years ago.
a theory explaining the structure of the earth's crust and many associated phenomena as resulting from the interaction of rigid lithospheric plates which move slowly over the underlying mantle

Which layer in this model represents the least dense layer of the geosphere? - А B C D
Answer:
A
Explanation:
The area that represents the least dense part of the geosphere is the portion or region A.
Density is the determined by the packing of a layer.
The geosphere is the solid part of the earth Since A denotes the crust, it is the least dense part of the earth. In particular, the continental crust is the least dense part of the earth. During the differentiation of the earth, denser minerals gravitated towards the center and the lighter ones partitioned to the surface. This makes the crust the least dense portion of the earthAnswer:
the answer is A

pt The crystal lattice structure of an ionic compound
A. is weak due to the interactions of the ion
B. is weak due to the independence of the ions
OC. is strong due to the interactions of the ions
D. is strong due to the independence of the ions
Answer:
D. is strong due to the independence of the ions
Explanation:
In an ionic solid, the ions are packed together into a repeating array called a crystal lattice.
The concept of crystal packing assumes that the ions are hard spheres. successive layers over it. The simplest arrangement is one in which the spheres in the base are packed side by side.The crystal lattice structure of an ionic compound is strong due to the interactions of the ions. Therefore, option (C) is correct.
What are ionic compounds?Ionic compounds can be defined as crystalline solids which are formed by closely packing ions of opposite charge due to the interactions of the ions. An Ionic compound is usually created when metal reacts with non-metal.
In ionic compounds, the ions are held together by ionic bonds due to the interactions of the ions. The ions are formed from atoms by gaining or losing electrons in order to attain their noble gas configuration.
A cation in ionic compounds refers to an electropositive ion and has the tendency to donate valence electrons. Similarly, anions in ionic compounds can be defined as electronegative ions and have a tendency to accept electrons.
In an ionic compound, there exists a large electrostatic force of attraction that forms a strong ionic bond.

How many moles of butane do we have if we have 5.50 x 1024 molecules
of butane (CH) ?
Answer:
9.14moles
Explanation:
Given parameters:
Number of atoms of butane = 5.5 x 10²⁴atoms
Unknown:
Number of moles = ?
Solution:
To solve this problem, we must understand that a mole of any substance contains the Avogadro's number of particles.
6.02 x 10²³ atoms makes up 1 mole of an atom
5.5 x 10²⁴ atoms will contain = [tex]\frac{5.5 x 10^{24} }{6.02 x 10^{23} }[/tex] = 9.14moles
