Bacteria have been classified based on

metabolism

When phospholipids and other molecules are placed into water, microspheres (primitive cells) form spontaneously. These microspheres are called.

Coacervates

Scientists believe that our atmosphere has progressively changed as some living organisms began to harness sunlight energy to split water molecules to form complex carbon molecules. This activity led to an increase in:

Oxygen

One big difference between spontaneous generation and prebiotic evolution is:

Prebiotic evolution occurred over a long time

An organism has just been located and needs to be placed into one of the domains of life. The characteristics that have been reported are multicellular and autotrophic. Based on your knowledge, in which domain should this organism be placed?

Eukarya

. A system of statements and ideas that explain a group of facts or phenomena is called a:

Theory

The idea that each species consists of actually or potentially interbreeding individuals that are reproductively isolated from other such groups is called the:

Biological species concept

A systematist is constructing a phylogenetic tree for a group (clade) of animals. He/she has determined the shared derived characteristics which are:

Inherited from the most recent ancestor

A friend asks you the difference in kingdoms and domains. You respond:

Domains are larger and more inclusive than kingdoms. There are three domains into which the six kingdoms can be divided

Protists are classified into a single kingdom because of which of the following features:

All of the following:

1. They are not fungi, plants, or animals

2. Most are microscopic, although some are as large as trees

3. Many are unicellular, but there are some colonial multicellular forms

4. All types of nutritional modes are formed

A biologist who classifies and names organisms is called a

Taxonomist

The oldest fossils resemble modern

Prokaryotes

Some protists produce seed-like structures called

Cysts

The single characteristic that sets prokaryotes apart from all other organisms is

The absence of a true nucleus

A prediction or educated guess in science is called

Hypothesis

Biologists classify organisms based on

Morphology, internal anatomy and DNA

Structures which are derived from the same body part in a common ancestor but may have different appearances and functions are called

Homologous structures

Bacterial genetic resistance to antibiotics is most often carried

In plasmids

Cnidarians (jellyfish) use tiny barbed spears for protection and to capture prey called

Nematocytes

Angiosperms (flowering plants) may be divided into two groups the _____and the _____.

Monocots and eudicots

In developing animals, the ectoderm is the tissue layer that gives rise to:

Skin

Because all bryophytes lack specialized vascular systems, they depend on free-standing water for

Photosynthesis and support

The tissue in plants that consists of living cells that transport sugars and other organic molecules from the leaves to the rest of the plant is called

Phloem

“Cot” as in monocots and eudicots come from the word

Cotyledon

A biologist discovered a new animal. Upon studying embryonic development, she observed radial cleavage with the blastopore developing into an anus. This animal was categorized as a

Deuterostoma

The person that influenced Darwin concerning overpopulation and food production was

Malthus

The result of a small subset of a large population establishing a new population is called

Founder effect

Environmentalism (environmental concern) is

Primarily a social concern that uses some of the ideas from ecology.

The potential for social interactions among individuals would likely be maximized when individuals

Have a clumped distribution in their environment

The reduction of deleterious (harmful) alleles in the population is a process called

Natural selection

“K” as in rN(K-N/K) refers to

Carrying capacity

Paleontology is the study of

Fossils

Species formation by geographical separation is called_____speciation

Allopatric

Describing in precise mathematical terms the process by which genetic variation is generated and passed on within population is called

Population genetics

A continuous variable is one for which within the limits of the variable range, _____values are positive

Any

The single most important factor increasing genetic variability in a population is:

The rate a mutagen spreads

Good evidence for the theory of gradual evolution would come in the form of

Fossil records of transitional forms between distinct species
