A piece of refrigerated, cooked meat will remain safe to eat for a longer period of time than a refrigerated piece of raw meat of similar size. Which statement is a valid inference based on this information?
Cooking meat kills many bacteria and fungi
Cool temperatures stimulate the growth of microbes on raw meat.
Raw meat cannot be preserved.
Cooked meat contains antibodies that destroy decomposers.
The ameba represented in the diagram below is a single-celled organism. Which two processes are most closely associated with structure A?
insertion and deletion
nervous regulation and circulation
active transport and diffusion
replication and photosynthesis
If the ribosomes of a cell were destroyed, what effect would this most likely have on the cell?
It would stimulate mitotic cell division.
The cell would be unable to synthesize proteins.
Development of abnormal hereditary features would occur in the cell.
Increased protein absorption would occur through the cell membrane.
If a gene is inserted into the DNA of a bacterial cell, every cell produced by that cell will have
DNA that is different from that of the other cells produced
a 50% chance of having a copy of the inserted gene
a copy of the inserted gene
a new type of DNA base
The shape of a protein is most directly determined by the
amount of energy available for synthesis of the protein
kind and sequence of amino acids in the protein
type and number of DNA molecules in a cell
mistakes made when the DNA is copied
If a chemical that interrupts cell division is added to a culture of human liver tissue, which process would stop?
meiosis
mitosis
breakdown of glucose
diffusion of nutrients
One possible pathway for the evolution of elephants is represented in the diagram. Which statement concerning this pattern of evolution is correct?
Evolution always results in favorable traits
Evolution does not always result in a species that will survive to present time.
Evolution leads to less complex organisms.
Evolution results in the same changes in all species.
A boy inherits genes for tallness, but his growth is limited as a result of poor nutrition. This is an example of
an inherited disorder
environmental influence on gene expression
expression of a hidden trait
a characteristic controlled by more than one pair of genes
The diagram represents a technique currently used by scientists in the field of biotechnology. Which statement describes a possible outcome of this technique?
The bacterium is able to produce the protein produced by the human cell.
It allows the bacterium to grow in humans, since it contains a human gene.
It allows humans to become immune to an infection from this type of bacteria
The bacterium can now produce human cells identical to cells of the DNA donor
Which statement describes starches, fats, proteins, and DNA?
They are used to store genetic information.
They are complex molecules made from smaller molecules
They are used to assemble larger inorganic materials.
They are simple molecules used as energy sources.
