What is needed for a species to survive?

Read this standardized test practice passage and answer the questions. You have seven minutes to complete the assignment.

 

Exactly what life is and how it starts is one of the most difficult problems in science. There is no simple statement that can be used to define life. The only sure way to define life is to describe its characteristics.

The seven characteristics of life are:

Composed of cells:

• Single-cell organisms have everything they need to be self-sufficient.
• In multicellular organisms, specialization increases until some cells do only certain things.

• Both molecular and cellular organization.
• Living things must be able to organize simple substances into complex ones.
• Living things organize cells at several levels:
  • Tissue - a group of cells that perform a common function.
  • Organ - a group of tissues that perform a common function.
  • Organ system - a group of organs that perform a common function.
  • Organism - any complete living thing.

• Living things take in energy and use it for maintenance and growth.
  • Go to physical science class to review the definition of energy.
  • Go to chemistry class to see how chemical energy relates to heat changes.

• Living things will make changes in response to a stimulus in their environment.
• A behavior is a complex set of responses.

• Cell division - the orderly formation of new cells.
• Cell enlargement - the increase in size of a cell.

• Reproduction is not essential for the survival of individual organisms, but must occur for a species to survive.
• All living things reproduce in one of the following ways:
  • Sexual reproduction - Producing offspring by the joining of sex cells.
  • Asexual repoduction - Producing offspring without the use of gametes.

• Adaptations are traits giving an organism an advantage in a certain environment.
• Variation of individuals is important for a healthy species.

Portfolio Assignment 021:
Scoring criteria

1. Do all living things have all of the characteristics of life? If your answer is no, give an example.
2. Name some non-living thing that uses energy.
3. Name some non-living thing that grows.
4. There are many theories used to describe how life started on Earth. Use the links provided for information to write one paragraph about each of these theories:
   • panspermia
   • carbonaceous chondrite
5. Another theory about the origins of life on Earth is called creationism. Read the description of creation from the first chapter of Genesis in the King James version of the Bible.
   1. Who wrote the book of Genesis?
   2. On which day did plants appear?
   3. On which day did the sun and moon appear?
   4. On which day did life appear in the oceans?
   5. On which day did animals that walk on the land appear?
   6. What was the last living thing to be created?

Did you use the Lab Key last week? As the labs become more difficult, the Keys will become more important to your success. The Lab Keys are here to help, but you must use them to plan what you will do in the lab before you come to class on lab day. Microscopes

Human life - abortion euthanasia
Heredity - parents and offspring
Genetics - genetic engineering manipulating genes cloning stem cells
Agricultural Biotechnology - improved crops and foods
Human rights - for the group or the individua
Animal rights - animal rights vs human rights
Drug use - unlimited implications
Use of the environment - at what financial cost
Quality of human existance - for which generation

In-class Assignment 023:
This assignment must be turned in by the end of class tomorrow to receive credit.

1. Review science essays.
2. Use this planning guide to write an essay about ethics in some area of life science.
3. Before beginning the essay, study this essay evaluation rubric. The rubric shows you how to make a good score on the essay.

Turn in the essay and the rubric with the self-evaluation portion completed to your science facilitator.
Remember to always staple the rubric on top of the assignment paper.

Individuals must reproduce if a species is to survive.

An essay must have at least three paragraphs.

The first paragraph is always the introduction.
The last paragraph is always the conclusion.
The paragraph(s) between compose the body.
