D. They connect muscles to tissues
im pretty sure its C, if im right please give me brainlist
The function where the bones of the skull mainly perfom should be that they protected the tissue and organs.
What is tissue and organs?Here the tissue and organs should be considered as the basic structural units with respect to the bodies.
Here the tissues should be comprise of the cell collections that have the same kind of function while on the other hand, the organ should be the tissue collections.
Therefore, it protected the tissue and organs.

Answer:
A. The clear liquid is less dense than the black liquid
Explanation:
Since the clear liquid since on top of the black one it's density is less. Whatever liquid has a higher density will sink to the bottom of the flask.

1. What is the atomic mass of hydrogen if 99.985% is hydrogen-1 and 0.015% is hydrogen-2?
The atomic mass of Hydrogen : 1.02985
Further explanationIsotopes are elements that have the same Atomic Number (Proton)
Atomic mass is the average atomic mass of all its isotopes
In determining the mass of an atom, as a standard is the mass of 1 carbon-12 atom whose mass is 12 amu
An atomic mass unit = amu is a relative atomic mass of 1/12 the mass of an atom of carbon-12.
Mass atom X = mass isotope 1 . % + mass isotope 2.% ..
99.985% is hydrogen-1 and 0.015% is hydrogen-2
The atomic mass of Hydrogen :
[tex]\tt atomic~mass~H=0.99985\times 1+0.015\times 2\\\\atomic~mass~H=1.02985[/tex]

Explanation:
A reaction begins with 130.5g of substance X and substance Y. How many grams of
substance X and Y are there at the end of the reaction?
A) not enough information provided
B) 100g
C) 65.25g
D) 130.5g
Answer:
130.5g
Explanation:
At the of the reaction, the combined mass of X and Y will be 130.5g.
The premise for this conclusion is based on the law of conservation of matter.
This law states that "in a chemical reaction, matter is neither created nor destroyed but changed from one form to another".
In essence, in a chemical reaction, there is no mass loss.
The amount of product in the reaction is expected to be the same as the amount of reactants used in the experiment. When we start with 130.5g then we should end with 130.5gLiquid or solid water that falls to the ground is called
When light pases through a prisim,white light will be separated into different colors. which statment best explains this observation?
Answer:
It's B
Explanation:
The classic rainbow is made of certain colors, so If a white light passed through a glass prism [and only glass] the rainbow would show because of the colors bending [the naked eye can't see that 0-0]
Also, you know the sky is blue right?? The color blue in that prism when the light shined over was the shortest and wavy color. each color has it's own wave. blue is just the shortest and waviest one.

What is the chemical formula for zinc (II) phosphate?
Answer:
Zn^3(PO4)2
Explanation:
thats the formula
The chemical formula for compound zinc (II) phosphate is Zn₃(PO₄)₂.
Zinc (II) phosphate is an inorganic chemical compound that is made up of zinc cations and phosphate anions .The chemical formula for zinc (II) phosphate is obtained by combining three zinc cations with two phosphate anions to achieve the neutral charge.
Chemical formula is a way of representing the number of atoms present in a compound or molecule.It is written with the help of symbols of elements. It also makes use of brackets and subscripts.
Subscripts are used to denote number of atoms of each element and brackets indicate presence of group of atoms. Chemical formula does not contain words. Chemical formula in the simplest form is called empirical formula.
It is not the same as structural formula and does not have any information regarding structure.It does not provide any information regarding structure of molecule as obtained in structural formula.
Thus, chemical formula for compound zinc (II) phosphate is Zn₃(PO₄)₂.

Think about your morning from when you wake up until you arrive at school. Describe the forms of energy you encounter or use during that time. (Use types of energy like electrical, mechanical, thermal, etc)
Answer:
When sleeping the energy exhibited is Potential energy. When I wake up and I’m preparing for the day I use kinetic energy which is the energy exhibited during motion.
Eating before leaving the house means I used chemical energy for replenishment of nutrients to aid the performance of more activities for the day. The food eaten and the physical activities also give rise to thermal energy which is why we sweat.

What element is in period 6 with 2 valence electrons?
Answer:
Barium
Explanation:
I think that's the answer
The element in period 6 with 2 valence electrons is Barium.
The periodic table has been organized into periods and groups. The period is in an horizontal arrangement while group is vertical arrangement. The elements that can be found in period 6 are Beryllium, Magnesium, Calcium, Strontium, Barium etc. Elements in the same group have the same number of valence electrons. This means that elements in group 2 have 2 valence electrons. Barium possess two valence electrons because it is in group 2 and it is also in period 6. Therefore, the element in period 6 with 2 valence electrons is Barium.Learn more at: https://brainly.com/question/24089206?referrer=searchResults
