A new medicine is out on the market that helps people retain information better (smart pill). In a recent study, one group was given the smart pill and the other group was given a placebo (sugar pill) both groups were graded on a math test. Identify: Control Group: Experimental Group: Independent Variable: Dependent Variable:

Identify the 4 unifying themes of Biology. Explain what characteristics an organism must have to be considered alive.

What characteristics does a living thing have? Let’s make a class list: 1.

Think – Pair – Share

1. All living things share common characteristics 2. All living things share common needs 3. Living Things meet their needs through interactions with the environment 4. The types and numbers of living things change over time

1) Organized i. All parts work together to take in nutrients and remove waste ii. Body plan allows it to survive in its environment

Living things are arranged in an orderly way. Cell- Smallest unit of life Ex. Liver cell Tissue- group of cells that have same structure and function (look alike) Ex. –Skin Organ- different tissues that work together to perform a function Ex-Kidney System- Group of organs working together Ex. Nervous System Organism- Organ systems working together (whole) Ex. Gorilla

TissueOrganSystem Kidney Bark Group of cells doing the same thing Intestines, stomach, mouth working together Outer surface of a leaf Heart, veins, arteries, Muscle

2) Made of 1 or more cells. Unicellular a) Small, hard to see b) directly exchange nutrients and waste with environment Multicellular a) Work together b) cells have specialized jobs and work together to keep organism alive

3) Growth and Development *Cell division and cell specialization*

4) Reproduction Asexual:Sexual: 1 Parent, 2Parents Same DNAMix DNA

1) All Living Things Share Common Characteristics 5) Responds to stimuli

6) Limited Life Span

1. ReproductionA. Bacteria are unicellular. 2. RespondsB. A seed turns into an oak tree. 3. Grows and Develops C. Dogs live for an average of 10 years. 4. Made of CellsD. All humans have digestive and respiratory systems. 5. OrganizedE. When a bug crawls on the venus fly trap, it closes. 6. Limited Life Span F. A cat gives birth to kittens.

Identify the 4 unifying themes of Biology. Explain the characteristics an organism must have to be considered alive

1) We need energy!! Energy is the ability to do work. The sun is the ultimate source of energy!

Can come from food and is converted into usable form, think calories Energy moves along food web, only 10% of energy transferred to each level

Autotroph (Producers) Heterotroph (Consumers) Herbivore Carnivore Omnivore Scavenger

2) Materials A.) Water -Cells contain mostly water - Reactions within the body that occur need water B.) Oxygen - for cellular respiration in animal and plant cells C.) Carbon Dioxide -for photosynthesis in plant cells D.) Nitrogen - For Proteins

3) living space Protection Sources of nutrients Area to grow and develop

1) Environment: everything that surrounds an organism. Living factors (biotic factors) Non-living factors (abiotic factors) Ex: sunlight, temperature, climate, rocks, etc.

2) Interactions- 2 or more things affecting each other.

Name at least 5 DIFFERENT interactions occurring in the following picture.

Biodiversity- variety of living organisms a. there are about 1.4 million different species b. Species- group of interbreeding organisms c. Fossils- are evidence of species existence; they have lived, died, and evolved over time.

What is an adaptation? characteristic of an organisms that allows it to better survive in its environment *Organisms within a species must adapt to changing environments or they will become extinct !!*
