salt in the solution moved against the concen. gradient

147
In this image you see DNA and its nucleotides; How do RNA nucleotides differ?
They are magical
They are the same
They contain Uracil instead of Thymine
They contain ATCG
148
There are similarities between prokaryotic and eukaryotic cells. Which structure is in both?
Nucleus
Lysome
Ribosome
Mitochondria
149
A plant is placed in a closed system w/ H2O & the sun. What will happen to the plant's growth?
plant will grow @ slower rate because it requires more H2O
plant will grow faster because it is sheltered from the wind
plant will die b/c it does not have CO2 for photosyn
plant will die because it does not have oxygen for photosyn.
150
The original sequence was ACG and the new sequence is ACA. Will this change the phenotype?
yes, because any change will change the phenotype
yes, due to new A.A
No, even though it changed it has the same A.A
It is impossible to determine
151
Which phase of mitosis is shown in the picture?
Anaphase
Prophase
Metaphase
Telophase
152
Which explains why cells that contained mitochondria-like organ. had an evolutionary advantage?
They were able to make more use of available energy
They had more DNA
They were immune to bacterial invasion.
They were able to photosynthesize
153
What is the relationship between these three structures?
The cell is composed only of DNA and protein.
Protein is composed of DNA that is stored in the cell.
DNA controls the production of protein in the cell.
DNA is made up of proteins that are synthesized in the cell.
