This type of meat is substance. If you were talking about meters then it would be a system of measurement.
Answer:
Mixture
Explanation:
Meat is composed of approximately 72–75 % water, 21 % nitrogenous compounds (19 % proteins and 1.5 % nonprotein nitrogen compounds which include nucleotides, peptides, creatine, and creatinine), 2.5–5 % lipids, 1 % non-nitrogenous compounds (vitamins) and carbohydrates (a very small amount of glycogen).

Describe what happens to kinetic energy of the molecules when temperature increases.
Answer:
When the temperature of an object increases, the average kinetic energy of its particles increases. When the average kinetic energy of its particles increases, the object's thermal energy increases. Therefore, the thermal energy of an object increases as its temperature increases.
Explanation:
That is all I know.
Which characteristic is related to kinetic energy but not potential energy
Answer:
kinectic is movement and potential is still
Explanation:
While kinetic energy of an object is relative to the state of other objects in its environment, potential energy is completely independent of its environment. Hence the acceleration of an object is not evident in the movement of one object, where other objects in the same environment are also in motion.
Answer:an object’s speed

1. Under what conditions can potassium bromide conduct electricity?
A only when melted
B. when melted or dissolved in water
C. only when it is in crystal form
D. only when dissolved
Answer:
potassium bromide can only conduct electricity when in an aqueous solution due to the electrostatic force between the ionic bonds
The potassium bromide can conduct electricity when melted or dissolved in water. Therefore, option (B) is correct.
What are ionic compounds?The crystalline solids which are formed by closely packed ions of opposite charge are called ionic compounds. In ionic compounds, the ions are connected with each other by ionic bonds in solis state.
The elements which can gain or lose electrons to attain their nearest noble gas configuration participate in the formation of ionic compounds. The solid ionic compound cannot able to conduct electricity.
In the melted state, the ions of K⁺ and Br⁻ can move from their fixed positions. Therefore, the KBr can conduct electricity when melted or dissolved in water.
The ionic compounds are able to conduct electricity in melted or dissolved in water. Because only in these states the ins can move freely while in the crystalline state the ions cannot move freely to conduct electricity.

As you were climbing a a mountain, you noticed that rocks were crumbling below your feet and moving down the mountain. What two processes did you observe?
Answer:
Weathering and erosion
Explanation:
Weathering can be explained as the breaking down of rocks/minerals on the surface of the Earth as a result of contact with biological organism, water, air and other factors
. There are 3 common types of weathering which are;
1) physical weathering
2) biological weathering
3) chemical weathering
Erosion can be regarded as a geological process, whereby earthen material are been transported away by natural forces, these forces could be wind as well as water.
Therefore, as you were climbing a a mountain, you noticed that rocks were crumbling below your feet and moving down the mountain. What is observed are weathering and erosion processes.
After the weakening and broken up of the rock by weathering then erosion transport the bit of the rock down the mountain as you are climbing, which means the "weathering process" breakdown and the "erosion process" involves the transport or movement of the bit of the rocks

Antimony-123 has a mass of 122.904 amu and a natural % abundance of 42.79
can you give the work aswell trying to understand how to do it
Answer:
Wow, now this one is a hard one, took me quite a while to figure it out but here it is
The abundances of the two isotopes is:
Antimony-121 = 57.2%
Antimony-123 = 42.8%

12. If the particles of a liquid are always moving, why don't they all come apart from each other and become a gas?
Answer:
even though the particles of a liquid are moving, they are attracted to each other so they don't spread far apart to become a gas.
Explanation:
"but some do when they evaporate"
In liquids, the particles are allowed to move freely rather than the solid. The gaseous particles can move more freely than liquids.
Particles in liquids:In liquids, the particles are placed randomly and thus are allowed to move freely but they do not become a gas as liquids are slightly less compressible than gases. Even though the particles of a liquid are moving, they are attracted to each other so they don't just spread far apart to become a gas.

The final temperature and pressure in a container is 234K at 210 kPa.
If initial temperature was 175 K, what was the starting pressure?
Answer:
Initial pressure = 157 kpa (Approx)
Explanation:
Given:
final temperature = 234 K
final pressure = 210 kpa
Initial temperature = 175 K
Find:
Initial pressure
Computation:
Initial pressure / Initial temperature = final pressure / final temperature
Initial pressure / 175 = 210 / 234
Initial pressure = 157 kpa (Approx)

Electromagnetic waves will travel the SAME SPEED (speed of light) WITHIN a medium as it does WITHOUT a medium. Question options: True False
Answer:
True
Explanation:
The speed that electromagnetic waves will travel within any medium is the same as those without a medium. The speed of electromagnetic wave is a constant and does not depend on the material of the medium.
Electromagnetic waves are waves that do not require a material medium for their propagation. They are able to pass through vacuums and mediums with particles at constant speed. It is mechanical waves whose speed is medium dependent. Mechanical waves have varying speed based on the mediums they move through.what particle joins or bonds atoms to form a compound or molecule

2. An all natural mosquito repellent
is trying to make its way into the
market. One arm is sprayed with the
repellent and one arm is not sprayed
with anything. After 3 hours, the
number of mosquito bites is counted. What is the control group
Answer:
The arm that was not sprayed with anything
Explanation:
The control group would be the arm that was not sprayed with anything.
The control group during an experiment is a group that forms the baseline for comparison in other to determine the effects of a treatment. The control group does not include the variable that is being tested and as such, it provides the benchmark to measure the effects of the tested variable on the other group - the experimental group. In this case, the experimental group would be the arm that was sprayed with the repellent.
