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.

Which state of matter does this model represent?
A} solid
B} liquid
C} gas
D} plasma
The state of matter represented by the above image is a liquid (option B).
What is matter?Matter is the basic structural component of the universe. Matter usually has mass and volume.
Matter exists in three states namely;
Solid: the particles of a solid are very attracted to each other. They are close together and vibrate in position but don't move past one another.Liquid: In a liquid, the particles are attracted to each other but not as much as they are in a solid.Gases: In a gas, the particles have very little attraction to each other. They are very far apart compared to the particles in a solid or liquid, and are constantly moving. The particles don't interact with one another but just hit and bounce off of each other when they collide.Based on the particles of the substance in the image above, one can observe that they are closely but not tightly packed, which suits the description of liquid state.
Therefore, the particles of the substance in the model represent a liquid.

The similar shapes of fast swimming marine predators are an example of:__________
Answer: convergent evolution
Explanation:
The similar shapes of fast swimming marine predators are an example of convergent evolution.
Convergent evolution shows how different species possess identical structures even though they evolve separately. Convergent evolution typically takes place with the organisms that are not really related.
An example of convergent evolution is the similarity that can be noticed in the wings or the flights of bats, birds, insects, etc
A carbon atom has four valence electrons. How do all living things depend on this property and other special chemical properties of the carbon atom?
Answer:
It is for the fact that Carbon need to fill up its shell for order to make it coplete. Hense using Covelant bonds. Carbon therefore can connect to oxygen, hygrogen, and other carbon molecules. Also Carbon can connect in 4 ways to. It also can form 2 main covelant bonds
Explanation:
I am a bio teacher
Carbon is an element with four valence electrons which makes it possible to
form covalent bonds with other elements such as Hydrogen, oxygen etc.
Carbon has four valence electrons and needs an additional four in order to
achieve a stable octet configuration. This makes it react with other
elements . When an element has fewer or no valence electrons in the outer
shell, it becomes less reactive to ensure the stable configuration isn't altered.
This is why carbon is able to pair electrons with other elements through
covalent bonding to ensure that the octet configuration is achieved.

If 30% of the nucleotides in a single-stranded RNA molecule are adenine, then what percent are expected to be thymine?
Answer:
Explanation:
the base pair of adenine is thymine they are equal in amount in RNA so if 30% of the nucleotide in RNA is adenine so the percentage of thymine would also be equal to adenine that is 30%
If the DNA strand has 30% Adenine in its composition, it means that the same DNA strand has 30% thymine in its composition.
This is because:
DNA is composed of the nitrogenous bases Adenine, Thymine, Cytosine and Guanine.These nitrogenous bases were paired with each other.Adenine pairs with Thymina. While Cytosine pairs with Guanine.Therefore, the amount of Adenine and Thymine in a DNA must be equal. While the amount of Guanine and Cytosine must be equal.In this case, we can conclude that if the DNA has 30% of Adenine, it is mandatory that this same DNA has 30% of Thymine.

an example of how water moves from
the biotic part to the abiotic part of an
ecosystem.
One of the important examples of how water moves from the biotic part to the abiotic part of the ecosystem includes transpiration of water from the surface of the leaves of plant.
What is Transpiration?Transpiration is the loss of water in the form of vapors from the surface of leaves of plant. Transpiration of water takes place from the stomata of plant cells.
Stomata are the specialized cells present on the surface of leaves which are covered by the guard cells that regulates the opening and closing of stomata and hence the movement of water from the leaf surface.
In transpiration, water from plant, a biotic part of ecosystem is lost in the form of vapors to the atmosphere, i.e., an abiotic component of ecosystem. The rate of transpiration is regulated by factors such as sunlight, concentration of ions like sodium and potassium, presence of starch.

E.Coli is a type of prokaryotic bacterium that is present in contaminated food. Which describes where the genetic material is found
A.cytoplasm
B.Cell membrane
C.Ribosome
D.Nucleus
Answer:
Cytoplasm
Explanation:
In prokaryotes DNA is located directly within the cellular cytoplasm
In the E.coli, that is, a prokaryotic bacterium, the genetic material is found in the cytoplasm.
The genetic material in E.coli:E.coli is a prokaryotic bacterium, and in all the prokaryotic cells, genetic information is carried on a single circular strand of DNA, which is either present in direct contact with the cytoplasm or is attached to the cell membrane.
In the prokaryotes, no enclosing membrane organelle is present, therefore, no nucleus is found. They comprises a concentration of DNA called nucleoid, which is not encircled by a nuclear membrane. Apart from this, no unique proteins are found attached with the molecule of DNA.
Thus, the correct answer is option A, that is, cytoplasm.

Fennec foxes (desert foxes) have ears up to 15 cm long. Thousands of years ago there was huge
variety in the size of the ears. Over time, those with the biggest ears were able to better survive as
they can lose more heat in the hot summer months. What would you expect to happen to the length
of Fennec fox ears if the temperature in the desert increases?
Answer:
You would expect their ears to also increase in size.
Explanation:
As the question says the ones with the biggest ears survived the best, implying if the temperatures rose the length of the ears would as well so that they could give off body heat.
