After watching videos from yesterday, answer these questions today (I email the quiz to the students and have them email answers, up to you whether you want them to take it as "open book", generally meaning they can Google the answers, or you expect an honors system of answering from memory). We have the Campbell Reece book, so my kids can use that, if they'd like.
Send your best answers to these as an email reply, using info from yesterday's biology videos.
1. Fill in the levels of biological organization in a hierarchy of complexity:
a_____
m______
c_____
t_______
o________
o__________
o_______
p__________
c_____________
e_________
b_____________
2. Give two examples of emergent properties.
3. Emergent properties are often described by the phrase, "The _______ is ___________ than the __________ of its __________".
4. List at least five characteristics of life.
5. Give two examples of biological states that are governed by homeostasis.
6. List at least three things prokaryotic cells and eukaryotic cells have in common.
7. List at least three things prokaryotic cells and eukaryotic cells differ in.
8. What is binomial nomenclature, and what is its purpose
9. Which language is used in biological taxonomy?
Extra credit: Why?
Extra credit: Give an example of negative feedback
Extra credit: Give an example of positive feedback
10. Put these categories in order from most to least broad:
genus
species
kingdom
phyllum
family
order
class
order
domain
Answers:
1.
atom
molecule
cell
tissue
organ
organ system
organism
population
community
ecosystem
biosphere
2. answers will vary, may include anything from molecules being less reactive than atoms to digestive system being able to digest food completely when one organ in it cannot.
3. the whole is greater than the sum of its parts
4. answers will vary, can include use of energy, reproduction, order, respiration, subjectivity to evolution, homeostasis, response to internal or external stimuli, growth and development
5. answers will vary, most will note body temperature, blood glucose levels, or pH.
6. will vary, may list cell membranes, DNA, cytoplasm, sometimes cell wall, ribosomes
7. will vary, may list membrane-bound organelles, true nucleus, ability to function in a multicellular way/ may simply list organelles prokaryotes don't have, such as Golgi apparatus
8. naming with two parts, the genus (capitalized) and species, in Latin and italicized, to specifically classify an organism within a taxonomic hierarchy
9. Latin
E.C. So biologists from all nations can know they are talking about the same organism
E.C. will vary, may note blood glucose being reduced when it gets too high with insulin or increased when it is too low with glucagon or other processes that have a compensatory response to an increase
E.C. will vary, may note uterine contractions in childbirth or any other process where the response to an increase is more increase
