Answer:
Hello!
*I'll include the names here and the definitions and properties in the explanation since they are descriptive.
Three States of Matter:
- Solid
- Liquid
- Gas
Explanation:
Matter:
Anything that has mass and occupies space (volume) is called matter. Basically, matter (and energy) constitute all the phenomena in the universe.
Composition of Matter:
1. Atom:
An atom is the smallest component into which matter can be divided. It contains charged particles such as electrons, protons and neutrons. It is the basic building block of all substances.
2. Element:
An element is a chemical substance that cannot be broken down into its constituents by simple chemical processes. For example, copper (Cu)
3. Compound:
A chemical substance formed by the combination or bonding of two or more atoms or elements. For example, NaCl is a compound that contains the elements sodium and chlorine linked together by chemical bonds.
4. Physical Properties of Matter:
Properties that are physically observable and quantifiable. All properties that can be studied without changing the chemical constitution of matter. Following are some examples of physical properties:
- Melting point
- Boiling point
- Lustre
- Shape
- Conductivity
- Mass
- Volume
- Density
- Length
5. Chemical Properties of Matter:
Properties that demonstrate a substance's ability to form chemical bonds (undergo chemical reactions) with other substances. Chemical properties are only observable or measurable if the state or chemical composition of the substance is changed. Some examples are:
- Chemical stability
- Flammability
- Reactivity (with acids, oxygen, bases, etc.)
- Oxidation/Reduction
- Radioactivity
Answer:
A single nucleotide polymorphism (change) exists between the two sequences.

The movement of food through the esophagus is called peristalsis.
<h3>What is the buccal cavity?</h3>
The mouth is what we generally call the buccal cavity. It is an opening that contains the teeth and the tongue. The tongue plays the important role of serving as the organ of taste while the teeth serves to marsh food. It is the white strong structure that occurs in the mouth that enables is to masticate our food. Also in the mouth we have the salivary gland which plays the role of secreting the saliva and we know that the saliva contains from enzymes that makes it possible for the digestion of food to commence at the moth. It the follows that the buccal cavity is made up of the teeth, tongue and salivary glands.
Food moves into the stomach via the esophagus. Thus movement is slow and is aided by the muscles that line the gastro intestinal tract. As such, movement of food through the esophagus is called peristalsis.

Answer:
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.

Answer: Option D
Explanation:
A fossil can be defined as the imprint or plant or animal that is preserved in the environment which can be used to known the organism or environment at that time.
The fossil formation takes place when the organism is trapped in ice, trapped in sap or it gets buried in fine sediments at the bottom of the lake.
In these cases the animals dies and remains as it is to form fossil but if incase the animals is completely decomposed by the bacteria and fungi then it cannot be transformed into a fossil as there will be no remains left.
The correct answer is option D
