Answer and Explanation:
The cell looks like a prokaryotic cell. A prokaryotic cell might be recognized by the presence of flagellates used to move (the four long filaments located posterior to the cell). There are also many pili surrounding the cell wall (the small little filaments). There are almost no organelles. There is a circular DNI molecule concentrated in a nucleoid (which seems to be the grey oval in the middle of the cell). Prokaryotic cells also have different compartments that depend on the type of cells, such as chlorosome, carboxysome, phycobilisome, and others (which might be the dark spiral circle in the anterior part of the cell). Two differences with the cell of an onion peel are that the onion peel cell has its genetic material surrounded and protected by the nucleus membrane, whereas the prokaryotic cell lacks a delimitated nucleus. Also, the onion peel cell has a hexagonal shape and lacks flagellates and pili, unlike the prokaryotic cell, which uses the to move. The onion peel is a multicellular structure, while the prokaryote is a one-celled organism. There should always be a cover glass over the cell or tissue we are looking at. Fasten the slide with the stage clips. Move the lens carefully in order not to damage it or the slide. Do not touch or clean the lens with the fingers and try not to stain them.Related Questions

A species which is carried into a new location by people is called an invasive species. An invasive species can damage the food chain of an ecosystem.
What is an invasive species?An invasive species is an introduced species which becomes overpopulated and harms the environment into which it is introduced. Although most of the introduced species are neutral or beneficial with respect to other species, an invasive species adversely affect habitats and bioregions, which causes ecological, environmental, and economic damage.
Some of the examples of invasive species are Zebra mussels are native to the Black Sea and the Caspian Sea in Central Asia. Zebra mussels arrived in the Great Lakes of North America accidentally.

Which process do all organisms do when performing cellular respiration?
Answers
Answer:
Glycolysis
Explanation:
Glycolysis is the first step of cellular respiration, where glucose is turned into 2 pyruvate molecules.
This step happens in all living organisms, since it does not require oxygen and also occurs in the cytoplasm, which all cells have.
So, glycolysis is the process that all organisms do during cellular respiration.

5. On vacation at a lake, Saira's mom sees an interesting-looking rock formation. Saira just learned
about rocks in geology class and tells her mom that the formation is made of gneiss, a type of
metamorphic rock. How did this metamorphic rock form?
Answers
Answer:it was heated and under pressure
Explanation:
Metamorphic rocks are formed from existing rocks, under high temperature and high pressure. This process is called metamorphism.
What is a metamorphic rock?Metamorphic rocks are those rocks that are formed from different kinds of rock like igneous, sedimentary, or gneiss rock under high pressure and intense temperature. They are rigid in nature.
In the formation of metamorphic rocks, firstly existing rock is broken down into small particles by physical, chemical, or biological agents. The process of breaking down rock is called weathering. Then erosion and transportation of these particles take place by the wind, water, or any biological agent.
The next step involves compaction after sedimentation. Thus, metamorphic rocks are formed from existing rocks.

Most of the cells in the body of an organism reach a certain size, stop growing after a certain size, and then undergo division. Cells maintain the cell number in body through continuous division. Thus, the given statement is true.
What are Cells?Cells are the basic unit of life. Cells are the building blocks of living organisms. The human body is composed of cells. These cells provide the structure for the body, take in nutrients from food, convert the nutrients into usable form of energy, and carry out specialized functions such as digestion, respiration, excretion, and circulation, etc.
Specialized cells in the body of an organism have a certain size and shape and these undergo growth and division. Cells undergo cell cycle which consists of different phases such as interphase and M-phase where the cell grows in size and shape and divides to form more cells and thus maintain their number.

Populations of organisms continuously increase over time. D. As environments change, individual organisms choose to change to better suit the new environment.
Answers
Answer: Option B.
Organisms that are able to survive and reproduce pass on characteristics to their offspring
Explanation:
