Geologic Time - 200Of the following, which one was least likely to be found in the earth’s early atmosphere?

Methane-CH4

Oxygen Gas-O2

Water Vapor-H20

Ammonia-NH3

Answer:

Oxygen Gas

NEXT QUESTION

Geologic Time - 300If 1.0 g of a radioactive isotope had a half life of 1 billion years, how much would be left after 3 billion years?

Answer:

0.125 g

NEXT QUESTION

Geologic Time - 400What organism was most helpful in creating an environment on land that was habitable? Answer:

Photosynthetic bacteria.

NEXT QUESTION

Geologic Time - 500

Answer: Radioactive isotopes decay at a specific rate. The rate is known as its half-life. This is the amount of time it takes for ½ of the material to decay.

NEXT QUESTION

How are radioactive isotopes used to determine the age of material ?

Evidence - 100

Answer:

Embryology

NEXT QUESTION

The similarity in early development of organisms represents which type of evidence?

Evidence - 200

Answer:

Vestigial Structures

NEXT QUESTION

What type of evidence is shown in this picture?

Evidence - 300

Answer:

Biochemical.

NEXT QUESTION

Looking at amino acid sequences to compare evolutionary relationships is what type of evidence?

Evidence - 400

Answer:

Analogous structures

NEXT QUESTION

Anatomical structures that have a similar function, but did not evolve from a recent ancestor are called what?

Evidence - 500Answer:

Vestigial,

Homologous, and

Analogous structures.

Examples will vary.

NEXT QUESTION

List three types of morphological evidence for evolution and one example of each.

The theories of life - 100

Answer:

Spontaneous generation.

NEXT QUESTION

The idea that living things could arise from non-living material is called what?

The theories of life -200Answer:

When a prokaryotic cell with heterotrophic characteristics engulfed(endo) an autotrophic cell. They lived in harmony, (symbiosis).

NEXT QUESTION

What is endosymbiosis?

The theories of life - 300

Answer:

Louis had an experimental flask that was open to the air containing the “Vital Force”with a swan neck. The broth did not support life.

NEXT QUESTION

How was Louis Pasteur’s experiment to disprove spontaneous generation different from either Francesco Redi’s or Lazarro Spallanzani’s?

The theories of life - 400Answer:

That early atmospheric gases could have formed organic compounds.

NEXT QUESTION

What did Miller and Urey’s experiment demonstrate?

The theories of life - 500

Answer:

Organisms that are more adapted to an environment will survive and reproduce to pass on those traits to their offspring.

NEXT QUESTION

Define natural selection

Natural Selection - 100

Answer: No. There is no selection for the better trait. Unwanted traits, such as poor health, may be inherited.

NEXT QUESTION

Will evolution occur if organisms mate randomly? Explain your answer.

Natural Selection - 200Answer: It takes more time to see genetic changes in the larger population.

NEXT QUESTION

Why will a small population evolve faster than a larger population?

Natural Selection - 300

Answer:

Genetic drift

NEXT QUESTION

The change in the allele frequency of a population over time due to random chance is called what?

Natural Selection - 400Answer:

Gene Flow

or immigration.

NEXT QUESTION

The introduction of new alleles into a population is called what?

Natural Selection - 500Answer:

1. Over production of offspring

2. Variation within a species exists

3. Organism will compete for limited resources.

4. Organisms who gain the resource, based on inherited traits, will survive and pass them on

NEXT QUESTION

List two of the four conditions needed for natural selection to take place.

All of the above -100

Answer:

Mutations

NEXT QUESTION

The major source of genetic variation.

All of the above - 200

Answer:

Fitness

NEXT QUESTION

The ability of an organism to survive and reproduce is called an organism’s what?

All of the above - 300

Answer:

Radioactive dating.

NEXT QUESTION

This is one way in which scientists can determine the age of once living organisms.

All of the above - 400Answer:

150,000 years

NEXT QUESTION

Calculate the age of a Calculate the age of a sample containing sample containing thorium -230(whose half thorium -230(whose half life is 75,000 years) after life is 75,000 years) after ¾ of the sample has ¾ of the sample has decayed. decayed.

All of the above - 500

Answer:

Convergent evolution.

NEXT QUESTION

The process by which unrelated organisms come to look like one another is called What?

First life forms - 100

Answer:

They were able to create organic compounds from inorganic compounds in conditions that replicated Earth’s early atmosphere.

NEXT QUESTION

What is the significance of the experiment Urey & Miller performed?

First life forms - 200

• What is the significance of coacervates and microspheres?

• Cell like structures, with some of life’s characteristics were created without genetic information.

• Microsphere= protein based membranes

• Coacervates= amino acids and carbohydraes

NEXT QUESTION

First life forms - 300

• What are three inferred characteristic of the first life form?

• Prokaryotic

• Heterotrophic

• Anaerobic

NEXT QUESTION

First life forms - 400• Answer:Both are

capable of creating organic compounds from inorganic one, but chemosynthesis uses chemicals(H2S) instead of sunlight.

NEXT QUESTION

What is the difference between chemosynthesis and photosynthesis?

First life forms - 500What role did cyanobacteria have in changing the early Earth’s atmosphere? Answer: It is an autotrophic algae. Its production of oxygen was helpful in creating the ozone shield

in the stratosphere.
