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

What is blood pattern analysis?To ascertain what actions could have produced the bloodstains and/or patterns shown, bloodstain pattern analysis studies are carried out.
Bloodstains can be divided into three categories: projected or impact stains, transfer stains, and passive stains. Passive stains, which can take the form of droplets, flows, and pools, are frequently caused by the weight of an injured body.
In order to determine if it is human blood and then create a DNA profile, analysts or investigators frequently soak up pooled blood or swab small quantities of dried blood. When there are numerous victims, this becomes extremely important. Thus, option B is correct.

Explain how the conversation of wetlands to farmlands has impacted stream and rivers
Answers
Answer:
Wetland reduction has caused a decrease in the absorption zones for excess water. If the excess water cannot be absorbed by the soil, it increases the incidence and magnitude of flooding.
The conversation of wetlands to farmlands has impacted stream and rivers as the Wetland reduction has been caused the decrease in the absorption zones for excess water. If the excess water cannot be absorbed by the soil, it increases the incidence and magnitude of flooding and this can be achieved by sustainability.
What is the process of achieving Sustainability?Sustainability can be achieved through careful resource management. By managing the resources and making proper use without wasting them ensures sustainability. The concept of sustainability demands careful and responsible people working towards a common goal of resources management.
A union is a term that refers to the association of workers of a company with the aim of defending and promoting their labor interests to the employer. The strike is a protest in which its members refrain from carrying out the activity they normally carry out to the detriment of those to whom they direct their claims.

An animal cell lacking oligosaccharides on the external surface of its plasma membrane would likely be impaired in which function ?
Answers
Answer:
This question lacks options, the options are:
A) transporting ions against an electrochemical gradient
B) cell-cell recognition
C) maintaining fluidity of the phospholipid bilayer
D) attaching to the cytoskeleton
E) establishing the diffusion barrier to charged molecules
The answer is B
Explanation:
Generally, oligosaccharides are short chains of polysaccharides/carbohydrates. They make up the structure of membranes including the plasma membrane. Oligosaccharides attached to the protein content of the cell membrane to form a substance called GLYCOPROTEIN. The attached oligosaccharides functions in the ability for a cell to recognize another cell.
According to this question, if an animal whose cell is lacking oligosaccharides on the external surface of its plasma membrane, the most likely impairment would be that of CELL-CELL recognition.
Oligosaccharides are a type of carbohydrates that contain the combination of a few monosaccharides. The are also found as part of the components of the membrane.
If an animal cell lacks this type of carbohydrates (oligosaccharides), the function impaired would be the cell-cell communication function.
Oligosaccharides performs various functions as part of the component of the plasma membrane. It functions in cell to cell recognition and binding and communication. They usually contain 3-10 sugar units (monosaccharides).Learn more: https://brainly.com/question/22301340

Scientists believe that Megalodon had six rows of 7-inch-wide, razor-sharp teeth, top and bottom, for a total of 276 teeth in its giant jaws! It's no wonder, then, that this ancient shark left so many of them behind. Without this trail of teeth, we would not know that these enormous creatures swam the ancient oceans as a top predator.Select two sentences from below that best show that the author wants the reader to be able to relate Megalodon's size to everyday life
