11
9
5
7
141
Why can bacteria recognize a human gene and then produce a human protein?
DNA replication in bacteria and humans is the same
Bacterial & human cells contain the same kind of chromosomes
Bacterial cells contain the same organelles as human cells.
The basic components of DNA are the same in human & bacteria
142
How are cellular respiration and photosynthesis related, in terms of energy?
Energy is not involved in either
energy captured in photosyn. is used to power cell respir
Photosyn and respir perform the same task in terms of energy
energy transformed in cell respir. is used to power photosyn
143
Which statement can be inferred from the evolutionary tree?
Species 1 is most closely related to Species 8.
Species 3 is most closely related to Species 7.
Species 5 is most closely related to Species 6.
Species 2 is most closely related to Species 3.
144
Which of the following is NOT one of water's special properties?
High Specific Heat Capacity
Density Anomally- less dense as a solid
High Surface Tension
High Viscosity
145
According to the phylogenetic tree, which organisms are least related to each other?
Insecta and Crustacea
Insecta and Myriapoda
Trilobita and Insecta
Trilobita and Chelicerata
146
What macro-molecules are involved in the cell (plasma) membrane?
nucleic acids
proteins
carbohydrates
lipids
147
Biochemical substances in the human body are maintained at about a neutral pH except for the -
Blood
Internal Material of living cells- cytoplasm
Stomach Fluids
Lymph nodes
148
Cell is permeable to sucrose, glucose, and water but impermeable to starch. Which is correct?
Glucose will diffuse into the “cell.”
There will be no net movement of glucose.
Starch will diffuse out of the “cell.”
Sucrose will diffuse into the “cell.”
149
There are similarities between prokaryotic and eukaryotic cells. Which structure is in both?
Mitochondria
Lysome
Ribosome
Nucleus
150
What does B, C, D represent?
B-exponential C- logistic D-carrying capacity
B- exponential C- carrying capacity D- logistic
B-logistic C-exponential D- carrying capacity
151
A person with swollen gums rinses his mouth with warm salt water, and the swelling decreases.
The swollen gums have absorbed the saltwater solution
salt in the solution moved against the concen. gradient
The saltwater lowers the temperature of the H2O in the gums.
H2O in gums moved out b/c high concen.of salt in solution
152
The original sequence was ACG and the new sequence is ACA. Will this change the phenotype?
It is impossible to determine
yes, due to new A.A
No, even though it changed it has the same A.A
yes, because any change will change the phenotype
