CORRECT ANSWERS GRADED A+
◍ what dependent variable was measured in the Bioconvection (pattern
formation) experiment?.
Answer: pattern formation time
◍ independent.
Answer: What is variable C?
◍ what is the name of the microscope in box 6?.
Answer: Light control knob
◍ predictions.
Answer: ____________________ are often written as "If X then Y"
statements. X and Y stand for the independent and dependent variables,
respectively.
◍ hypothesis,experiments,hypothesis, method, prediction.
Answer: The ________________ leads to predictions, which can be tested
through __________________. These three elements can be combined to
state the research hypothesis:If '_____________', and '______________',
then '________________'.
◍ what is the name of the microscope in box 4?.
Answer: condenser
◍ What is the name of the microscope part in Box 1?.
Answer: Ocular Lense
◍ what is the name of the microscope in box 5?.
Answer: Iris Diaphragm
, ◍ You are given ethanel with a stock concentration of 100 m
M. Calculate the ethanol volume for a master mix with a Anal ethanol
concentration of 1 mM in a final volume of 10 ml. Show your calculations
by typing them here:.
Answer: C1V1=C2V2(100mM)(V1)=(1 mM)(10mL)V1= 0.1 mL0.1ml=100
uLEthanol stock needed 0.1 mL (100 ul). Add 9.9 mL of solvent/buffer to
reach final volume of 10 mL with 1 mM ethanolFREE RESPONSEE
◍ Model Organisms.
Answer: species that are used to study certain aspects of biology.
◍ prokaryotes.
Answer: a Common model organism for _____________________ is E.
coli.
◍ pH extremes disrupt __________ which maintains the 3-D structure of
enzymes.
Answer: hydrogen bonding
◍ a farmer suspects that crows are eating his berries before he can pick them
from his field, so he does an experiment. The farmer has 12 rows of berry
bushes in his field, and covers half the rows with a net: this prevents birds
from landing on the (netted) bushes and eating berries. Half of the
bushes/rows are left uncovered. Over the course of 8 weeks, he counts the
berries harvested from each row of bushes in the test field. What are the
independent and dependent variables in this experiment?.
Answer: the independent variable is 'presence/absence of nets' and the
dependent variable is 'number of berries harvested'.
◍ How do you think the fungus may be inhibiting the function of the enzyme?.
Answer: The fungus may be changing the pH inside the sweet potato,
moving the enzyme away from its optimal pH. Enzymes function best
within a specific pH range, and changes in pH can alter the enzymes shape
and reduce its ability to bind to the substrate. This would decrease the
activity of beta-amylase and inhibit the enzyme's function. FREEEEE
