A.What is biology? B.What are the two divisions of biology?

3. At the end of the lesson, student should be able to :
State what the study of biology
Explain the important of Biology
List the different field of study in Biology
List careers related to Biology
state various way of studying Biology
know how scientific investigation has
been carried out

4. Biology….. What is ‘Biology’ mean???????
From Greek words ~~~ bios - life
logos - study
Study of living organism
Study of biology~ study of living things, their environment, and the interaction between them

5. Biology
Study the origins and history of life and once- living things - evolution
Study the structures of living things - anatomy
Study how living things interact with one another - ecology
Study how living things function - physiology

6. Importance of biology Enable us to :
Finding cure for diseases, new meds
Preserve the environment (help endangered animals)
Appreciate the diverse variety of living things
Develop technologies –heart valves, prosthetic limbs
Improve agriculture

7. Medicine and public health
KNOWLEDGE OF BIOLOGY

Study of tissues

9. Career related to biology
Medicine

10. Characteristics of Life
To be considered alive = an organism must have or had all of these characteristics
A characteristic is a trait, feature, or quality

11. The Characteristics of Life
Made of one or more cells
Cells are the basic unit of structure and function in all living things.
Living things can be unicellular (one cell) or multicellular (many cells).

Introduction to Biology

12. Displays organization

14. Or new cells and structures Changes over the lifetime
GROW AND DEVELOP
GROWTH- adding mass-
Or new cells and structures
Development- natural
Changes over the lifetime
Of an organism

16. Reproduce Reproduction = the production of offspring
Organisms that can breed with one another and produce fertile offspring are know as a species.
Reproduction is not essential for the survival of an individual, but it is essential for the continuation of the species.

19. Ways of studying biology
Science process skill
Promote thinking
Manipulative skill
Psychomotor skill via conduct experiment in scientific investigation
Scientific skill

20. Any examples?

21. NEED energy from food.
Most plants and some unicellular organisms use light energy from the Sun to make their own food.
Organisms that cannot make their own food get energy by consuming other organisms.

22. GROWTH And Development Made of cells Reproduce Displays organization

23. Respond to stimuli
Anything part of the environment that causes some reaction by the organism is a STIMULUS
You lean on stove which is still hot –
What happens?
You move your hand away – this is the response or reaction to the stimulus

24. Scientific investigation
Identify problem
Observed situation
Identify variable
State problem
Forming hypothesis
-make general statement about relation between manipulated variable and responding variable
Plan the experiment

25. REGULATE INTERNAL CONDITIONS TO MAINTAIN LIFE
Maintain homeostasis
REGULATE INTERNAL CONDITIONS TO MAINTAIN LIFE

26. conduct the experiment Analysis and interpreting data
Collecting data
Analysis and interpreting data
Forming conclusion
Hypothesis is accepted if result support the hypothesis while rejected if the result do not support the hypothesis
Writing a report

27. examples
Hunger
Thirst
Temperature
Blood sugar
Water balance
Blood pH

29. Lets do a scientific investigation
Situation 2
Situation 1

30. Adaptation over time
Any inherited characteristic or trait that results from changes in a species over time
Helps them survive so best genes are passed on

31. Recent examples
Lactase persistence- recent dairy consuming people – maintain lactase which usually is no longer produced after age 1
Increase of sickle cell carriers in certain areas – protects them from malaria

32. Bitter taste receptors help protect you from ingesting dangerous or deadly plants, substances

33. Science notebook pages 2-3
Exercise your brain!!!!
