Answer:
No
Explanation:
According to science, human beings can't observe cells and other tiny organisms with our naked eyes coz our eyes aren't strong enough to observe but we can use a microscope which has strong lenses.
As cell is a tiny microscopic structure, it can be visible under microscope only.
what are the types of cell ?Cell is the basic unit of any living organism, can be observed in animal, plant, microbes etc; Bacteria are unicellular in nature, all higher eukaryotic organisms are multicellular in nature like plants and animal cell.
The simplest type of cells are prokaryotic cells have a cell membrane, cytoplasm where all of the metabolic processes occur, ribosomes where protein synthesis occur, and nucleoid which carry genetic information, reproduce by binary fission.
The eukaryotic cells have cell membranes, cytoplasm, ribosomes, and nucleus a house of DNA, rough endoplasmic reticulum for protein assembly, smooth endoplasmic reticulum for lipids, Golgi apparatus for protein sorting and exporting.
It has mitochondria energy house, a cytoskeleton for structure and passes information, and lysosomes or peroxisomes for digestion of waste, vacuoles for water storage, chloroplasts for photosynthesis.

use the concept of natural selection to explain why organisms typically adapt over time
Answer:
natural selection is the process by which organisms which are not as well adapted to their environment do not survive long enough to pass their less favorable traits on to the next generation of their species
Explanation:
Answer:
Natural selection is the process by which organisms which are not as well adapted to their environment do not survive long enough to pass their less favorable traits on to the next generation of their species. Eventually, the more favorable traits are incorporated into a species as the organisms that had those traits survive while the ones who do not die. This process takes time because it occurs through individuals with the favorable traits passing those traits on to future generations. Typically, the less favorable traits will not be eradicated in one generation.

describe a difference between large and small proteins
Answer:
Small proteins are called peptides
Explanation:
Both peptides and proteins are made up of strings of the body's basic building blocks – amino acids – and held together by peptide bonds. In basic terms, the difference is that peptides are made up of smaller chains of amino acids than proteins. As a general rule, a peptide contains two or more amino acids.

What is an Ecosystem?An ecosystem may be defined as a place or an area where members of different species live together and interact with one another for the purpose of food, shelter, and space.
The Ecosystem comprises all biotic and abiotic factors of any geographical location. The Biosphere only includes the living forms where they efficiently live and play their roles. Habitat is the area where a particular type of organism is best adapted due to natural selection.
Therefore, the matching of each term with respect to its description is appropriately described above.

Can a hypothesis be proven true? Why or why not?
Answer: Hello! xoxo
Upon analysis of the results, a hypothesis can be rejected or modified, but it can never be proven to be correct 100 percent of the time. For example, relativity has been tested many times, so it is generally accepted as true, but there could be an instance, which has not been encountered, where it is not true.

like.
Pre-Lab Question 4: Why is it important to know what a negative test result looks like?
I
Answer:
I feel it's to easily differentiate the positive from the negative...... like in gram staining of bacteria, the colour tell us which bacteria is gram positive or gram negative...... I just feel that this is science and it is advisable to know what the opposite result of an experiment should look like.
