Answers

1
Which compares Eukaryotes (E) and Prokaryotes (P)?
E have membrane-bound organelles, P do not
E have a cell wall while P have cell membranes
E use active transport while P use facilitated diffusion
E use flagella to move while P can not move at all
2
If a defect prevented a protein catalyst 2 be produced, what would happen N a cell w/ reactions
the reaction would happen somewhere else in cell
Cell find different protein catalyst
reverse reaction would start
reaction w/ that protein catalyst would go slowly or not
3
Which characteristics defines a cell as a Eukaryote?
Have a nucleus
Being able to move
Being able to reporduce
Have a cell wall
4
Compare structures in Animal Cells (AC) and Plant Cells (PC)?
PC have Rough ER & golgi bodies, AC have smooth ER & lyssome
AC do not contain chloroplast, cells, central vacuole, PC do
AC have cell walls & central vacuole, PC have many vacuoles
PC dont have mitochondria or ribosomes while AC do
5
If lactic acid is being formed from pyruvate, what would explain why?
Glucose is being made as a result of aerobic conditions
CO2 is also being produced as pyruvate moves
Fermentation is taking place as a result of a lack of oxygen
Krebs cycle is happening & products will enter mitochondria
6
Once DNA has replicated in a cell, what is the next step in the life of an adult cell?
Cell will begin to divide into daughter cells
Cell will start replication process again
Cell will manufacture mRNA
Proteins will be created in nucleus
7
Why is the invention of the microscope important to biology?
created a means for funding cell research
gave scientific credibility to those working on cell theory
Allowed for development of the cell theory
created public interest and support for research

brown eyes is dominate to blue. What explains how two brown eyed parents have a blue eyed child
eye color is sex linked and only males could be blue eyed
One parent must have had only blue eyed parents
Each parent must be carrying recessive allele for blue eyes
Only mutations in gametes could produce this
10
In a pea plant cross, 89 plants had purple flowers, 31 white flowers. What are the parents?
Both parents are heterozygous for flower color
One was Heterozygous the other was white flowers
Both parents were homozygous for purple
1 was Heterozygous the other was homozygous 4 purple flowers
