Definition Of Life (Practice Quiz) - Quiz

Major Summative for 10 Blue Biology Students.

Questions and Answers

1.

Describe the characteristics of early earth.
2.

Which of these is not a characteristic of all living things?
- A.
  
  Ability to Reproduce
- B.
  
  As a group, species evolve.
- C.
  
  Uses Oxygen.
- D.
  
  Grows and develops over time.
Correct Answer
C. Uses Oxygen.

Explanation
All living things have the ability to reproduce, as it is a fundamental characteristic of life. As a group, species evolve over time through natural selection and adaptation. Growth and development over time is also a common feature of living organisms. However, not all living things use oxygen for their survival and metabolic processes. Some organisms, such as anaerobic bacteria, can survive and function without oxygen. Therefore, the characteristic of using oxygen is not applicable to all living things.

3.

An organism that requires oxygen to live is an organism.

Correct Answer
Aerobic

Explanation
An organism that requires oxygen to live is called aerobic. This term refers to organisms that utilize oxygen for their metabolic processes, such as respiration. Aerobic organisms are able to generate energy more efficiently through the breakdown of organic molecules in the presence of oxygen. They can be found in various environments, including terrestrial and aquatic habitats.

In Linnean Taxonomy, what is the order of classification (least specific-most specific)
- A.
  
  Domain, Kingdom, Class, Phylum, Order, Family, Genus, Species
- B.
  
  Domain, Kingdom, Phylum, Order, Class, Family, Genus, Species
- C.
  
  Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species
- D.
  
  Species, Genus, Family, Order, Class, Phylum, Kingdom, Domain
Correct Answer
C. Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species

Explanation
The Linnean Taxonomy is a hierarchical system of classification used to categorize organisms. It starts with the broadest category, which is the domain, followed by the kingdom, phylum, class, order, family, genus, and species. This order of classification, from least specific to most specific, allows for a systematic organization of organisms based on their shared characteristics and evolutionary relationships.

5.

Animalia is a domain.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
Animalia is not a domain, but rather a kingdom in the classification of living organisms. The domain is a higher level of classification that encompasses multiple kingdoms, including Animalia. Therefore, the statement "Animalia is a domain" is incorrect.

Rate this question:
6.

Name the three domains.
- A.
  
  Eukyra
- B.
  
  Bacteria
- C.
  
  Animalia
- D.
  
  Archea
Correct Answer(s)
A. Eukyra
B. Bacteria
D. Archea

Explanation
The correct answer is Eukarya, Bacteria, and Archaea. These three domains represent the highest level of classification for all living organisms. Eukarya includes all organisms with eukaryotic cells, which have a nucleus and membrane-bound organelles. Bacteria are prokaryotic organisms that lack a nucleus and membrane-bound organelles. Archaea are also prokaryotic organisms, but they have distinct genetic and biochemical characteristics that differentiate them from bacteria. Together, these three domains encompass the diversity of life on Earth.

7.

A derived characteristic must be passed down to every species in a clade.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
A derived characteristic is a trait that is unique to a particular species or group of species within a clade. It is not necessary for this characteristic to be passed down to every species in the clade. Some species within the clade may possess the derived characteristic, while others may not. Therefore, the statement that a derived characteristic must be passed down to every species in a clade is false.

8.

Unlike Linnean Classification, a Cladogram details both similarities and differences of species as well as .

Correct Answer
Time

Explanation
A Cladogram not only illustrates the similarities and differences of species but also provides information about the evolutionary relationships and the sequence of branching events over time. It shows the chronological order in which species have evolved from a common ancestor, allowing us to understand the temporal aspect of species divergence and the progression of evolutionary changes.

9.

The organisms that first released oxygen into the environment were .

Correct Answer
Cyanobacteria

Explanation
Cyanobacteria were the first organisms to release oxygen into the environment through photosynthesis. These bacteria are capable of converting sunlight, carbon dioxide, and water into glucose and oxygen. This process, known as oxygenic photosynthesis, played a crucial role in the development of Earth's atmosphere and the evolution of life. Cyanobacteria are considered to be the ancestors of chloroplasts in plants, which also carry out photosynthesis to produce oxygen.
