Although crystalline, colloid, glassy, amorphous, and plasma phases are thought to exist, the three basic phases of matter are solid, liquid, and gas (vapor). A phase change is defined as the transformation of a phase from one form to another. Thus, option 1. C, 2. A , 3. D, 4. B is correct.
What are different phases of matter?Depending on the pressure and temperature circumstances, a given set of matter can change its state or phase, transitioning to different phases as these variables change to favor their existence.
The primary distinction between a substance's phase and state can be summed, For instance, a solid can convert to a liquid when the temperature rises.
A substance's phase describes its uniform chemical and physical qualities, whereas a substance's state describes its shape at a specific temperature and pressure.
Therefore, A phase change from a solid to a liquid represent melting.

What was the most common form of sea life found in Oklahoma? dolomite trilobite bryozoans apatosaurus
Answer:
The correct answer is: trilobite.
Explanation:
Trilobites were the most common form of early sea life found in Oklahoma. Trilobites were arthropods that are now extinct. This marine species is thought to have lived during the early Cambrian period and they existed for almost 300 million years, before disappearing at the end of the Permian in the Permian-Triassic extinction event.
Dolomite is a sedimentary carbonate rock that is rich in calcium.
Bryozoans are a species of seaweed-like aquatic invertebrate animals that have lived since the early Ordovician period.
The Apatosaurus was a herbivore dinosaur that lived in North America during the Jurassic period. They had very long necks and were related to the Brontosaurus.
How does the acidity of acid rain compare to the acidity of natural rainwater
Answer:
The acidity level of water is measured by the pH scale. Pure water has a pH of 7, which is neutral. However, natural rainwater actually has a pH of 5.6 because it gets exposed to the gases in the atmosphere, making it a bit acidic. True acid rain will have a pH level measuring from 5.0-5.5.

Which pair of scientists discovered the double helix structure of DNA? A. Faraday and Maxwell B. Newcomen and Watt C. Bragg and Bragg D. Watson and Crick
Answer:
Faraday and Maxwell discovered helix structure of DNA
Answer:
Watson and Crick discovered the double helix structure.
Explanation:
The nitrogen base pairs in the DNA molecule are adenine and or cytosine and .
The nitrogenous bases Adenine form two hydrogen bonds with thymine and the cytosine form three hydrogen bonds with the guanine. Simply, A combines with T and G combines with the C. It is often called as a complementary base pairing because of each base pair bonds only with its specific complementary base partner in a DNA molecule.
The nitrogenous bases Adenine form two hydrogen bonds with thymine and the cytosine form three hydrogen bonds with the guanine.
What are Nitrogen bases?A combines with T and G combines with the C. It is often called as a complementary base pairing because of each base pair bonds only with its specific complementary base partner in a DNA molecule.
The creation of nucleotides, which in turn create the nucleic acids like DNA and RNA, uses a set of five nitrogenous bases.
The sequencing of these bases in DNA and RNA is how information is stored, making them of utmost importance. The nucleotides A C U G are represented by the letters that make up the codons in the genetic code.
Therefore, The nitrogenous bases Adenine form two hydrogen bonds with thymine and the cytosine form three hydrogen bonds with the guanine.

Based on the images taken through Stella’s microscope, which cell structures could be clearly identified using a compound microscope?
Answer:
Use 400 x in order to study the structure clearly.
Explanation:
Cell structures could be clearly identified when magnify the microscope about 400 x by using a compound microscope. Due to high magnification power of compound microscope, the individual is able to see different structures that are present in cells. while by using lower magnification, the individual is unable to see different structures clearly. So use high magnification in order to study the cell.

How do organisms use oxygen
Organisms that use oxygen need it for cellular respiration, in which energy is released from glucose. Energy is needed by the organism for growth, mobility and reproduction.
Answer: Almost all living things need oxygen. They use this oxygen during the process of creating energy in living cells... Animals form other half of the oxygen cycle. We breathe in oxygen which we use to break carbohydrates down into energy in a process called respiration.

In what way would bacteria that require a pH of 11 for
growth respond to being placed in an environment with a
pH of 2?
Answer:
Explanation:
If the bacteria is required to be in highly basic conditions, putting it in highly acidic conditions would disrupt the internal functions of the bacteria which tends to kill the bacteria.
The way that bacteria that require a pH of 11 for growth respond, replaced in a pH of 2, will respond in the way: the bacteria must be in extremely basic circumstances, exposing it to excessively acidic settings will disturb its internal functions, eventually killing it.
What is pH?The optimum pH for bacterial growth may differ. Some bacteria, known as acidophiles, can thrive in an acidic environment, while others, known as alkalinizes, can grow in a base environment, and the remainder, known as neutrophils, can grow in a neutral pH environment.
Bacteria can keep their internal pH stable by creating acid, base, or buffer. If the surrounding pH is too acidic, the bacteria can produce a base to reduce the H+ concentration. If the conditions are excessively alkaline/basic, the bacteria can make acid through fermenting.
Therefore, Bacteria that require a pH of 11 for growth will respond in the following manner: the bacteria must be under extremely basic circumstances; exposing it to highly acidic settings will disrupt its internal functions, finally killing it.
