BIO 1001 EXAM PREP QUESTIONS AND
100% VERIFIED CORRECT ANSWERS!!
Characteristics of Male Drosophila
lower abdomen/body is black
patches of bristles on front legs
Characteristics of Female Drosophila
egg sticking out of lower body (known as sex combs)
Paper Clip Experiment:
1) Independent Variable
2) Dependent Variable
3) Control Treatment
4) Control Variable
1) Eyes opened/closed
2) # of clips picked up
3) Removing clips with both eyes opened
4) Time/size of container/process of removing clips/# of clips available
Wild Type Characteristics of Drosophila (2)
black body, red eyes
Compound vs Dissecting:
1) magnification
2) resolution
,3) FOV
4) DOV
5) working distance
Compound is:
1)higher
2) higher
3)lower
4) smaller
5) smaller
Labeling variables of experiment on graph:
X=, Y=
X= independent variable y= dependent variable
Iris Diaghram:
Controls...
light/power correlation
controls contrast via amount of light that goes through;
higher power=less light
1 vs 2 Sources of Light
1 source (compound microscope) better for smaller objects; 2 light sources (dissecting) allows
better light for larger/thicker/opaque objects
If viewing the letter "e", which microscope will show an inversion of the image?
, Dissecting
Magnification and DOF, FOV, working distance
higher mag. = lower DOF
= smaller FOV
= smaller working distance

1) Oscillatoria
2) Gloeocaspa
Oscillatoria- characteristics (4)
- cyanobacteria
-fliamentous
-green
chloroplasts, cell wall
Closterium- characteristics (2)
- pyrenoids
-nucleus
Pyrenoids- def, where found?
found in closterium
Lactobacillus
Lactose, found in yogurt
