Properties of Life (7)

Living things...
  1. have order
  2. process energy (obtain fuel)
  3. respond to the envrionment (results i movement or behaviors, senses)
  4. reproduce
  5. grow and develop
  6. homeostasis (regulate)
  7. have evolutionary adaptations (modifications that make organisms suited to way of life, allow diverse roles)

1

What explains the diversity of life?

Adaptation to different environments 

(Theme: Diversity and Unity of Life)

2

What do similar characteristics explain?

The unity of life

(Theme: Diversity and Unity of Life)

Unity: all life has same origen

  • organisms at a basic level are similar
  • cells, DNA, metabolic reactions, embryos
  • suggests living things descended from a single cell

3

What is the process that makes modification (evolution) possible? How?

Natural selection, by increasing frequency of traits that enhance survival and reporductive success

4

What does the organization of properties do?

It gives living things emergent properties that are due to the arrangement and interaction of the parts

5

Emergent Properties

created by the interaction between levels of biological organization and are new, unique characteristics.

6

Themes of Biology (8)

  1. The cell is an organism's basic unit of structure and function
  2. New properties emerge at each level in the biological hierarchy
  3. Organisms interact with other organisms and the physical environment
  4. Life requires energy transfer and transformation
  5. Structure and function are correlated at all levels of biological organization
  6. The continuity of life is based on hertiable information in the form of DNA
  7. Feedback mechanisms regulate biological systems
  8. Evolution

levels of biological organization

Biosphere->Ecosystems->Communities->Populations->Organisms->Organs and Organ Systems->Tissues->Cells->Organelles->Molecules

8

Reductionism

simplifies complex, broad subjects into pieces that are more manageable to study

9

Why is the cell the basic unit of structure and function?

It is the smallest unit that can perform all functions required for life.

10

Three domains of life (and organisms included in each)

Bacteria - prokaryotes

Archaea - prokaryotic archaea

Euarya - eukaryotes (plants, fungi, protists, animals)

11

Mechanism for descent with modification, who thought of it, and how?

Natural selection

Darwin

He noticed that individuals vary in traits and variation is passed on, a population can produce more offspring than can survive, and species are adapted to their environment

12

Adaptive radiation

Many new species are formed from one common ancestor due to different environmental conditions

13

Explain how natural selection may result in adaptation

Over time, weak traits in a species will eventually die out and the stronger trait will be far more prevalent, resulting in adaptation

14

Inductive reasoning

reach a general conclusion by looking at many observations

15

Deductive reasoning

Taking a general conclusion and breaking it down into parts

16

Hypothesis, hypothesis-based reasoning

A potential answer to a well thought-out question.  

Reaching a conclusion based on a set of potential hypothesis'

17

A scientifc hypothesis should be...?

testable and falsifiable

18

Scientific theory and how differ from a hypothesis

A scientific theory is much broader in scope than a hypothesis.  A theory is supported by a lot of evidence and is accepted by most as true. 

19

Science vs. Technology

Science is used to understand natural phenomena, while technology applies scientific knowledge for a specific purpose.
