1
Review Game Quiz 2 CP Biology Ms. Albu
2
Directions Grab a whiteboard & marker You will be given 30 seconds to chat (Quietly: don’t give YOUR answer away) with your group Write down your final answer Read answer to class Each team with a CORRECT answer receives a POINT Most points= winner
3
List the steps of the scientific method in order Problem Research/Discussion Hypothesis Experiment Data Conclusion
4
What are the 5 characteristics of life? Made of cells Obtain/Utilize Energy Reproduce Respond to stimulus Growth and Development
5
Scientists test hypotheses by…. Doing experiments
6
Define Metabolism All the chemical activities of an organism or cell
7
Describe the difference between growth and development To grow means to get bigger and to get bigger; more cells must be added. Development means to change into ADULT FORM
8
What is ATP? The form of energy obtained from the breakdown of glucose in cellular respiration Energy source for cells that is used in metabolism
9
Define Cellular Respiration The process by which glucose is broken down to produce energy for the organism in the form of ATP molecules
10
Define Autotroph & Give an example (2 points) converts sunlight energy into chemical energy through the process of photosynthesis PRODUCER
11
Identify which happens in Animals, plants, or both: 1) Photosynthesis 2) Cellular Respiration
12
Define an independent and dependent variable Independent “Cause”: What is changed, what is tested, the x-axis of the graph Dependent “effect” What is measured, result of the experiment
13
GIVE 2 EXAMPLES OF HOMEOSTASIS Temperature regulation Blood pH regulation Blood glucose regulation
14
Explain why Yeast is living [2 mins: 2 Points]
15
Name the 2 types of cellular respiration Aerobic Anaerobic
16
Ms. Albu mixes yeast with warm water, sugar (glucose) and observes bubbles. What is process is going on? This is proof for which characteristic of life Cellular RESPIRATION OBTAIN/UTILIZE ENERGY
17
Explain why Fire is living or non-living. 2 Mins
18
Explain evolution HAPPENS OVER MANY GENERATIONS Change in a species over time ~99% of all organisms that were once living are now extinct Either have adaptations to survive and reproduce or die off
19
Which type of cellular respiration requires OXYGEN Aerobic Respiration
20
Why do scientists need a control group? Keep 1 group constant as means of comparison To see effect of variables tested
21
Define HOMEOSTASIS Maintaining internal conditions Organisms utilize a lot of energy to maintain homeostasis
22
A hypothesis has to be….. measurable, Testable Plausible/educated guess If____, then____
23
3 points: What is the independent & dependent variable? What kind of visual representation is this?
24
MAKE A HYPOTHESIS Does yeast metabolize sugar and produce a gas? Hypothesis: IF____________, THEN_______________.
25
Put in order of increasing complexity: Tissue, molecules, organ, cell, organ system, organism Molecules Cell Tissue Organ Organ system Organism
26
Give TWO examples of an organism responding to the environment (stimulus) Shivering Animal distress calls Change of coat color with season change Birds migrating Fight or flight (adrenaline) Pupils dilate in lower light Reflexes (hot stove)
27
Your blood pH is normally 7.4. Your body works to regulate that it is maintained at 7.4- this is an example of ____________? Homeostasis
28
What are the types of Asexual reproduction? Binary Fisson Budding
29
Define HETEROTROPH ingest or eat other organisms in order to obtain chemical energy Also known as consumers
