Which of the following is NOT a principle of the cell theory?

Cells are the basic units of life.
All living things are made of cells.
Very few cells reproduce.
All cells come from existing cells.

Correct Answer

A. Very few cells reproduce.

Explanation

The principle of the cell theory states that all living things are made of cells, cells are the basic units of life, and all cells come from existing cells. However, the statement "Very few cells reproduce" contradicts this principle, as cells are capable of reproducing through processes such as cell division. Therefore, "Very few cells reproduce" is not a principle of the cell theory.

Which of the following contain a nucleus?

Prokaryotes
Bacteria
Eukaryotes
Organelles

Correct Answer

A. Eukaryotes

Explanation

Eukaryotes contain a nucleus. Unlike prokaryotes, which lack a nucleus, eukaryotes have a membrane-bound nucleus that houses the genetic material (DNA) of the cell. The nucleus is responsible for controlling the cell's activities and contains the instructions for protein synthesis and cell reproduction. Bacteria, on the other hand, are prokaryotes and do not have a nucleus. Organelles, such as mitochondria and chloroplasts, are found within eukaryotic cells and have their own internal membranes, but they are not considered to have a nucleus.

Say you want to study the effectiveness of giving a rubric to students in order to see whether it helps them or not. You take two relatively equal biology classes, teach them the same material, and give them the same test. However, you only give one of the classes a study guide for the test. Which of these statements about this experiment is false?

The independent variable in the experiment is the use (or not) of a rubric.
The dependent variable in the experiment is the performance of the students on the test.
The control group in the experiment is the class that did not receive a rubric.
The data (average lab report grades on a 0-100 scale) is going to be qualitative.

Correct Answer

A. The data (average lab report grades on a 0-100 scale) is going to be qualitative.

Explanation

The data (average lab report grades on a 0-100 scale) is going to be quantitative, not qualitative. Quantitative data involves numerical values that can be measured and analyzed statistically, such as grades on a scale of 0-100. Qualitative data, on the other hand, includes descriptive information that cannot be easily measured or quantified. In this experiment, the data collected would be quantitative as it involves numerical values representing the students' performance on the test.

One defining characteristics of ‘life’ is that it keeps its internal conditions relatively stable, also known as…

Reproduction
Homeostasis
Evolution
Photosynthesis

Correct Answer

A. Homeostasis

Explanation

Homeostasis refers to the ability of an organism to maintain stable internal conditions despite changes in the external environment. This characteristic is essential for the survival and functioning of living organisms. It involves regulating various physiological processes such as body temperature, pH levels, and nutrient balance. By maintaining internal stability, organisms can ensure that their cells and tissues function optimally. Reproduction, evolution, and photosynthesis are important processes in life, but they do not directly relate to the maintenance of internal conditions.

While keeping a colony of pet termites, you change brands of termite food. It seems to you that the termites are growing much more quickly with the new food. You want to test the effect of your new termite food on the rate of growth in the termites. The best design for a controlled experiment would be to divide your termites equally into two separate colonies and…

Feed them different amounts of the new food.
Feed them each the same amount of the new food.
Feed the termites in one colony the old food, and the termites in the other colony the same amount of the new food.
Feed the termites in one colony the old food, and feed the termites in the other colony half of the new food since it seems to be more nutritious.

Correct Answer

A. Feed the termites in one colony the old food, and the termites in the other colony the same amount of the new food.

Explanation

The best design for a controlled experiment would be to divide the termites equally into two separate colonies and feed them each the same amount of the new food. This design allows for a direct comparison between the two groups, as they are both receiving the same amount of food. By only changing the type of food and keeping the amount constant, any differences in the rate of growth can be attributed to the new food.

When you consume a serving of broccoli, you represent which trophic level?

Producer
Primary consumer
Secondary consumer
Tertiary consumer

Correct Answer

A. Primary consumer

Explanation

When you consume a serving of broccoli, you represent the primary consumer trophic level. Primary consumers are organisms that directly feed on producers, which in this case, would be the broccoli. They are herbivores that obtain their energy by consuming plants. Since you are consuming the broccoli, you are considered a primary consumer in the food chain.

Heterotrophs are also called

Producers
Autotrophs
Consumers
Self-feeders

Correct Answer

A. Consumers

Explanation

Heterotrophs are organisms that cannot produce their own food and rely on consuming other organisms for energy. They are commonly referred to as consumers because they consume and feed on other organisms to obtain nutrients and energy. Unlike autotrophs, which are able to produce their own food through photosynthesis or chemosynthesis, heterotrophs depend on external sources for their sustenance. Therefore, consumers is the correct term to describe heterotrophs.

Which of the following constitutes its own domain of life?

Animals
Fungi
Protists
Bacteria

Correct Answer

A. Bacteria

Explanation

Bacteria constitutes its own domain of life because it is a distinct group of single-celled organisms that have a unique cellular structure and genetic makeup. Bacteria are prokaryotes, meaning they lack a nucleus and other membrane-bound organelles. They have a wide range of shapes and sizes and can be found in various environments, including soil, water, and the human body. Bacteria play crucial roles in nutrient cycling, decomposition, and symbiotic relationships. They are also responsible for causing various diseases in humans, animals, and plants.

In order to answer this question, you will need to do work (in a scientific sense) on the keys of your computer. Your finger pushing the key is an example of kinetic energy. Stored energy in your finger allows you to release this kinetic energy. How is that potential energy stored?

In the position of your finger
In the chemical bonds of food molecules
In the shape of your finger
In your finger's thermal energy

Correct Answer

A. In the chemical bonds of food molecules

Explanation

Potential energy is stored in the chemical bonds of food molecules. When we eat food, our body breaks down the molecules through digestion, releasing the stored energy. This energy is then used by our muscles to perform various tasks, including pushing the keys on a computer. Therefore, the potential energy stored in the chemical bonds of food molecules is what allows us to convert it into kinetic energy and perform physical actions.
