Write three observations that could help you identify a fish.

Answers

The three observations that could help an individual in distinguising whether the organism is a fish or not is that it should live under water as fish can't survive without water, another thing is that it should laid eggs when it comes to giving birth because when it does not lay eggs but produces a living organism normally without an egg, it is considered to be a mammal and lastly, the appearance it possess such as having gils or fins.

Answer:

It has a single fin on its back near its tail.

It is covered in spots.

It has a forked tail fin.

It has a long and narrow body

After witnessing plant and animal cells under a microscope, which conclusion did scientists Schwann and Schleiden make about living organisms?

Answers

Answer:After witnessing plant and animal cells under a microscope, scientists Schwann and Schleiden made the conclusion that all living organisms are composed of cells. This discovery was significant because it laid the foundation for the cell theory, which states that cells are the basic units of life.

Schwann, a zoologist, observed animal tissues and noted that they were composed of individual cells. Schleiden, a botanist, made a similar observation while studying plant tissues. Both scientists realized that cells were the fundamental building blocks of living organisms.

This conclusion was supported by several examples. For instance, when examining plant cells, Schwann and Schleiden noticed that they had a cell wall and a distinct nucleus. Similarly, animal cells lacked a cell wall but had a nucleus and other cellular components. These observations led them to propose that all living organisms are made up of cells, regardless of whether they are plants or animals.

The discovery of the cell as the basic unit of life revolutionized biology and had a profound impact on our understanding of living organisms. It provided a unifying principle for the study of life and opened the door to further research and discoveries in the field of cell biology.

A scientist has correctly gone through all the possible steps in a dichotomous key, but has not identified an insect. Which most likely describes why he did not identify the insect?

Answers

The answer to this question is letter C. The organism evolved during identification.
A scientist has correctly gone through all the possible steps in a dichotomous key, but has not identified an insect. He was not able to identify the insect because the organism evolved during identification.

Choices to this question are:
A) The scientist must have made a mistake.
B) The insect might be an unknown variation or a new species.
C) The organism evolved during identification.
D) The dichotomous key had to many questions.

Answer;

The insect might be an unknown variation or a new species.

Explanation;

A dichotomous key is a biological tool that is used by scientists to identify unknown organisms. It is used to identify organisms in an ecosystem such as trees, mammals, fish, etc.
Dichotomous key consist of a series of steps or statements about a specific characteristics of organisms that leads to the correct name of a given organism.
If the scientist went through all the possible steps correctly in a dichotomous key and was unable to identify the insect, it means the insect might have been unknown variation or a new species.
