Euglena, Amoeba and paramecium are unicellular organisms. Euglena moves by flagellates, Amoeba by pseudopods and paramecium moves using cilia.
What are unicellular organisms?Unicellular organisms are lower level organisms having only one cell and an undeveloped nucleus. Most of them are aquatic lives and moves using some special organelles.
Amoeba moves by an arm-like structure emerging from its body and contains microtubules within the arms. Euglena is flagellated microorganism moving by flagella.
Paramecium is an aquatic unicellular microorganism having special whip like structure called cilia which moves it in back forth. Ciliary bodies are like oars to move in a direction.
Therefore, amoeba moves by pseudopodium, euglena moves by flagella's and paramecium moves by cilia.

7. If you were unsuccessful in locating the epicenter, describe how you could modify
seismograph resources to find the epicenter successfully.
Answer:
Down below
Explanation:
I would modify seismograph resources by requesting reports from earthquake stations that felt the tremors. I would then use the reports and look at the arrival time of the p waves and the s waves. If a station recorded the s waves arriving much quicker than the others, I can safely say that the epicenter was in that area. From there, I can request reports in that area and use the triangulation method to pinpoint the exact location.

When chromosomes are duplicated before cells divide, in a process called?
Answer: The process is called Mitosis
Explanation: Mitosis is the process in which a eukaryotic cell (cell containing a nucleus) separates its already duplicated chromosomes (copied during the S phase) into two sets of chromosomes so there will be two identical nuclei. It is generally followed by cytokinesis which divides the cytoplasm and cell membrane.

Label all of the components of this DNA structure with the following terms: Phosphate sugar backbone, nitrogenous base, hydrogen bonds.
Answer:
Phosphate sugar backbone:
The sugar-phosphate backbone forms the structural framework of nucleic acids, including DNA and RNA. This backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.
Nitrogenous base:
Nitrogen bases are the molecules that make up the steps of the ladders. There are four different nitrogen bases, namely; Guanine, Thymine,Adenine and Cytosine.
Pyrimidines are compounds that make a single 6-sided ring. Examples of pyrimidines are Cytosine and Thymine.
Purines on the other hand make 5-sided and 6-sided rings. Examples of purines are Guanine and Adenine.
The nitrogen bases are helped together through hydrogen bonds.
Hydrogen Bonds:
A weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in the other.

5 form in mountainous regions
6 wider and more gradual base
Answer:
U- Shaped Valley:
#3
#5
#6
V-Shaped Valley:
#1
#2
#4
Explanation:
just did the test
U-shaped valley include action of glaciers, form in mountainous region, and wider as well as more gradual base. V-shaped valley is formed by strong streams, erosive, and deeper than they are wide.
What is a valley?Valleys are low-lying areas of land that have been eroded and washed away by the combined elements of gravity, water, and ice. Some dangle, while others are feeble. They are all in the shape of a "U" or "V."
Humongous frames of snow and ice slowly creep downhill, seeking the least resistance. As the glaciers seep, they start picking up rocks and grind away at the valley floor and sides, forming a "U" and transforming the "V" into a "U." When the glacier melts, it leaves a U-shaped valley where the snow flowed.
U-shaped valleys are formed by glaciers, have a wider and more gradual base, and are found in mountainous areas. Strong, erosive streams form a V-shaped valley that is deeper than it is wide.
Thus, V-shaped valley include options 1, 2, and 4. U-shaped valley is 3, 5, and 6.

Answer:
hey! the answer is D. ((A newly formed volcanic island)))
The type of environments is most likely to experience the arrival of pioneer species is a newly formed volcanic island. Thus, option D is correct.
What is environmental change?
Environmental change has a change or the disturbance of the climate which has been most often causes due to the human behavior, human activity or the natural ecological processes.
Environmental change has been consists many factors, such as the natural disaster, human interferences, or animal interactions. It has been also included physical change. Environmental change can also refers to the long-term shift in the temperature and weather patterns. These shifts may be the natural, such as through variations in the solar system.
In environmental change natural systems transform the sun's energy into living matter and cause changes by cycling material through geological, biological, oceanic and atmospheric processes. So environmental change has serious issue to our human society.

Explain the movement of initial energy from the sun through an energy pyramid.
Answer:
An energy pyramid is a model that shows the flow of energy from one trophic level to the next along a food chain. The pyramid base contains producers—organisms that make their own food from inorganic substances. Thus, the higher the trophic level on the pyramid, the lower the amount of available energy.
Even though it cannot be produced or destroyed, energy is emitted as heat at each level. Only 10% of energy is essentially transferred from one level to the next.
What energy from the sun through an energy pyramid?The amount of energy diminishes and the levels get smaller as you progress up the pyramid, via the trophic levels to primary, secondary, and tertiary consumers.
A figure that depicts the quantity and flow of energy transfer within an ecosystem is called an energy pyramid. The trophic levels of an ecosystem's food web serve as the basis for energy pyramids.
An energy pyramid is a diagram that depicts the movement of energy up a food chain from one trophic level to the next. Producers—organisms that create their own nourishment from inorganic materials—are found at the base of the pyramid.
Therefore, This means that the amount of available energy decreases with increasing trophic level on the pyramid.
