Steadying body temperature and maintaining consistent blood pH levels are both examples of what unifying principle of life?

All living organisms use energy

All living organisms maintain organization

All living organisms have evolved over the course of many generations

All living organisms maintain some level of homeostasis

All living organisms are composed of similar structures

A plant will begin flowering in response to changes in length of daylight, temperature, and light quality. This is an example of what unifying principle of life?

Plants conduct photosynthesis

Living organisms maintain homeostasis

Living organisms interact with their environemt

Living organisms grow and develop

Populations of organisms evolve from one generation to the next

All of the chemical reactions responsible for releasing energy and building up molecules and tissues are essential and happening every moment of our lives. This is an example of ____.

_______ is/are largely responsible for the traits of living organisms while DNA provides the blueprint for the organization, development, and function of living things

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

A variety of finch species within the Hawaiian Islands have acquired different types of beaks needed for utilizing specific food resources over a long period of time. What is the likely process by which these different species of finches came about?

Horizontal gene transfer

Vertial descent with modification

An accumulation of harmful genetic mutations

An accumulations of neutral mutations

What feature of genetic mutations can eventually lead to the evolution of new species?

Mutations always produce harmful effects

Mutations never affect protein structure or function

Mutations are not a mechanisms through which biological evolution occurs

Mutations always produce beneficial effects

Mutations produce changes in the DNA sequence of a gene

How does evolutionary change occur?

Through the modification of characteristics in a preexisting population

It happens when there is no diversity or variation in a population

It happens only when genetic mutations are absent

None of these choices is correct

In the process of biological evolution, new species may evolve through direct echange of genes from one species to another, different species. This process is called:

The grouping or classification of species is termed:

Proteomics

Taxonomy

Genomics

Systematics

When grouping organisms, which classification level among these answer choices is most general for a particular type of organism?

If a scientist were studying the role of different proteins in the regulation of insulin secretion from a pancreatic cell, they would be studying:

Genomics and molecular biology

Proteomics and cell biology

Systematics

Anatomy

An explanation for a biological process that is substantiated by a large body of evidence is called a:

Collecting data without a specific hypothesis in mind is called:
