1. short chains of sugars attached to proteins in the cell membrane make up the:?
C) communication proteins - these oligosaccharides can act as cellular communicators between proteins

2. which of the following is a function of the plasma membrane?
B) controlling the passage of substance into and out of the cell - small, hydrophobic substances are allowed to cross the membrane

3. Which of the following is a function of proteins in cells? 2 answers.
A) produces vesicles for transport - E.g. Sar1 and clathrin and examples of proteins that aid in the production of vesicles
E) transports nutrients into the cell - True, for proteins like carrier and channel proteins. This answer is definitely correct

4. integral proteins span the entire phospholipid bilayer of the cell membrane.
A) true - it is possible

5. You just went to a party, where you ate 5 pieces of cake. You have eaten much more food than you require for making ATP. Which of the following will happen?
C)Glycolysis will speed up - to break down the excess glucose

6. If a cell has 20 individual chromosomes and it undergoes meiosis, how many cells will result, and how many single chromosomes will they contain?
A) 4 cells, each with 10 chromosomes - sure about this

7. on a hike along the desert slope of the Sierra Nevada Mountains in California, you notice that there is an abundance of pinyon pine and juniper trees. We would identify these 2 plants as:
B) ecological dominants - they are species in abundance

8. The coral organisms on a coral reed cannot be replaced by any other organism. For that reason, we identify those species as:
D) keystone species - very sure about this

9. a harmless moth that resembles a poisonous wasp is an example of:
B) mimicry - very sure about this. Think about the word 'mimic', what it is.

10. a small woodlot develops in an abandoned agricultural field. This is an example of:
B) secondary succession - It's not 'new' land since it was used before.

11. Which of the following happens when living organisms begin to colonize a new island formed from an underwater volcanic eruption?
A)primary succession - This is 'new' land, hence it is primary succession.

I hope you let more people try to do your homework as number 16 is most definitely NOT glucose but rather a derivative of it. Try looking it up yourself, it seriously would not take you that long. Just do keyword searches.. like for number 16 google liver and carbohydrate storage. I don't mind helping when people are stuck on just one or two points but twenty-one parts? And Holiday Homework? Meaning you've had since before Christmas to do this and are now panicking because vacation is almost over?
