Biology Chapter 1 Flashcards

The grouping or classification of species is termed?

In the binomial nomenclature, the first word refers to which taxonomical grouping?

All of the chemical reactions used to break down nutrients and build up components within the body are collectively known as?

What is the appropriate order of the stages when generating and testing a hypothesis?

The complete protein composition of an organism is called its?

Which of the following is likely NOT a common feature shared among all living organisms?

If a scientist was studying the interaction of different proteins in the regulation of insulin secretion from a pancreatic cell, he or she would be studying?

Whether the external temperature is hot or cold, birds maintain an internal body temperature of approximately 40°C. This is an example of?

Changes in ________ represent the predominant cause for biological evolution.

The main difference between a hypothesis and a scientific theory would be that?

The cells in the pancreas function differently than your cells in your skin because?

The phenomenon through which populations of organisms change over several generations is termed?

Taxonomy and Nomenclature

Taxonomy refers to the classification of species into groups.
Scientific naming follows a binomial nomenclature; for example, Homo sapiens.
In this classification, the first word represents the genus.

Metabolism and Biological Processes

Metabolism encompasses all chemical reactions that break down nutrients and synthesize components in the body.
Catabolism involves breaking down molecules, while anabolism refers to building up molecules.

Hypothesis Testing

The process of hypothesis testing includes:
- Observing a natural phenomenon.
- Leading observations to hypothesize an explanation.
- Conducting experiments to test predictions.
- Analyzing data to accept or reject the hypothesis.
The stages of hypothesis testing occur in the order: 3, 4, 1, 5, 2.

Proteomics and Biological Characteristics

The complete protein composition of an organism is termed its proteome.
Not all living organisms share the same structural composition, highlighting diversity.
Studying protein interactions in cells involves both proteomics and cell biology.

Homeostasis and Adaptation

Homeostasis describes the ability of organisms, such as birds, to maintain stable internal conditions despite external changes.
Changes in genetic makeup are the primary driver of biological evolution over generations.

Distinction Between Hypothesis and Theory

A hypothesis is a specific, testable statement, while a scientific theory provides broad explanations based on robust evidence.

Cellular Function and Proteomes

Different cell types, like pancreatic and skin cells, have distinct proteomes that result in varied functions.

Biological Evolution

Biological evolution is defined as the change in populations of organisms over generations.
