which two body systems are primarily responsible for locomotion
Locomotion and movement are brought about by skeletal and muscular system of the body. It’s a coordinated event of the skeletal and muscular system brought by contraction and relaxation of muscles.
How does locomotion occur in our body?
Locomotion occurs with help of specialised muscles, muscular and non-muscular by nature.
It involves the interaction of muscles (tendons and ligaments) and skeletal joints and cartilage
Locomotion is a voluntary action which require involvement of the nervous system.
In muscles actin and myosin protein forms cross bridges, consuming ATP.
Hence, to bring about locomotion skeletal and are responsible.

A chemist heats a gas within a sealed, rigid container. Which statement describes the changes that occur in the gas? (1 point)
-The gas particles move slower and hit the sides of the container with less force, consequently, the pressure
increases
-The gas particles move slower and hit the sides of the container with less force, consequently, the pressure decreases
-The gas particles move faster and hit the sides of the container with more force, consequently, the pressure
increases
-The gas particles move faster and hit the sides of the container with more force, consequently, the pressure
decreases
When a gas is heated in a sealed container, the gas particles move faster and hit the sides of the container with more force leading to an increase in the pressure of the gas.
An increase in the temperature of a gas increases the collision rate of the molecules of the gas according to the kinetic theory.
With increased kinetic energy, the molecules of the gases collide more frequently with each other and the walls of the container.
The collision creates an increase in the magnitude of pressure inside the container.

Answer:
C
Explanation:
When a gas is heated in a sealed container, the gas particles move faster and hit the sides of the container with more force leading to an increase in the pressure of the gas.

1: How can you divide Pepper & Sand to make a solution?
Answer:
Mixture of sand, pepper powder and salt can be separated by dissolving the mixture into water. Sand and pepper powder is insoluble in water while salt is soluble. So they are separated by the filtration method.
Using the “rule of 8” explain why carbon is the backbone of organic molecules
Answer:
Carbon has 4 valence electrons (electrons that are used in bonding), and therefore it can make 4 bonds which is the most one can (other than some exceptions, but in general it is the most). It wants to make 4 bonds so it can reach a full octet of 8 elections, hence the rule of 8.
Explanation:
Answer:
I suggest you See Explanation. But tldr: Carbon forms four bonds with no lone pairs.
Explanation:
By "rule of 8" I am assuming you mean "Octet Rule." In case you don't know, the octet rule (or rule of 8) is a rule referring to the maximum number of valence shell electrons that an atom can hold: 8 electrons. However, there are exceptions to this: octet-deficient and expanded octet atoms. Octet-deficient atoms follow what is known as the duet rule (or rule of 2), as seen in the case of H and He, or have have a capacity of up to 6 electrons in their valence shell, as seen in the case of B and Be. Expanded octets contain 10, 12, or even 14 electrons and occur in Period 3 elements and after. (It was previously assumed that this was due to d-orbital hybridization but that hypothesis has been disproven and currently an explanation regarding expanded octets doesn't exist. Yet another Nobel Prize worthy concept to solve when you have free time!)
Anyways, how does this all apply to Carbon being the backbone of the millions of organic molecules? Well, carbon follows the octect rule. Unlike duet rule atoms, it is not limited to one bond with another atom. Neither does it hold many lone pairs to itself nor form over four bonds at once causing a decrease in stability. No, Carbon forms four bonds with no lone pairs and has perfect stability in terms of both formal charge and octect rule in many of its structures. Its capacity to bond to up to 4 atoms without comprimising stability is the reason why carbon is the backbone of organic molecules.

Is a graph that starts at 25 and drops to 21, stays the same in temperature an endothermic reaction or an exothermic reaction?
Answer:
Explanation:
Endo and Exo thermic are defined by what changes take place in the environment of the reaction.
If the temperature goes up, the reaction is giving up heat. It is Exothermic.
If the temperature goes down, the reaction requires heat. It is Endothermic.
In this case, the temperature went down. The reaction is Endothermic.

What is the mass of 0. 513 mol Al2O3? Give your answer to the correct number of significant figures. (Molar mass of Al2O3 = 102. 0 g/mol) 0. 513 mol Al2O3 = g Al2O3.
The mass of a 0.513 mol of Al2O3 is 52.33g.
HOW TO CALCULATE MASS:
The mass of a substance can be calculated by multiplying the molar mass of the substance by its number of moles. That is;
mass of Al2O3 = no. of moles of Al2O3 × molar mass of Al2O3
According to this question, there are 0.513 moles of Al2O3.
Mass of Al2O3 = 0.513 × 102
Mass of Al2O3 = 52.33g
Therefore, the mass of a 0.513 mol of Al2O3 is 52.33g.

determine the bond type (NP, Polar, Ionic)
Answer:
a. NP
b. NP
c. Polar
d. Ionic
e. Polar
Explanation:
The way I did it was using the electronegativity of the elements mentioned and subtracted the pairs. For non polar the difference is 0-0.4, for polar it’s 0.4-2.0, for ionic it’s >2.0. I included the chart I used to find the electonegativity for the elements below.
B: 2.04, P: 2.19, difference is 0.15, so NP
Be: 1.57, Si: 1.9, difference is 0.33, so NP
C: 2.55, Na: 0.93, difference is 1.62, so Polar
Li: 0.98, O: 3.44, difference is 2.46, so Ionic
Mg: 1.31, N: 3.04, difference is 1.73, so Polar

what are Metals that are less reactive than alkali metals and alkaline-earth metals called
Answer:
The first ionization energies (I1) of the alkaline earth metals are not as low as the alkali metals. The alkaline earth metals are therefore less reactive than the alkali metals (Be and Mg are the least reactive of the alkaline earth metals). Several physical properties of these elements are compared in Table 7.7.

formulas and nomenclature binary ionic compounds worksheet
To name the binary ionic compounds it is necessary to observe which is the metal and the non-metal that compose them.
This name is made as follows:
The name of the metal is shown.The name of the non-metal is presented in abbreviated form.Add the suffix "ide" at the end.An example of this can be seen in the binary ionic composite KCL that receives the name Potassium Chloride, since potassium is the metal and chlorine is the non-metal.
It is important to remember that binary ion compounds are electrically charged ionic molecules formed by a metal and not a non-metal.
