Which organelle is responsible for packaging proteins for transport outside the cell?
golgi complex
endoplasmic reticulum
nucleus
ribosome
How does the molecule's structure relate to its function?
The phospholipid creates energy molecules and can be broken down with other lipid molecules to repair organelles in a cell.
The phospholipid does dissolve in water and can associate with other lipid molecules to form a barrier between the inside and outside of a cell.
The phospholipid can bind to large and small molecules and break down the molecules to move them across the outer membrane of a cell.
The phospholipid can bind protein molecules and can help move the proteins throughout the cytoplasm in a cell.
Which process requires energy from food to help a cell maintain homeostasis?
a phosphate ion being released from ATP
a phosphate ion being added to ADP
the conversion of glucose to oxygen
the creation of RNA from DNA
How are meiosis and fertilization a benefit to sexually reproducing organisms?
All offspring will have the most desirable traits from each parent.
All offspring will have traits that are identical to their siblings but different from their parents.
All offspring will have unique genetic variations and sets of alleles.
All offspring will have the same probability of acquiring mutations in their genes.
Which statement describes the offspring produced from asexual reproduction?
All of the offspring are identical to each other.
All of the offspring are unique to each other.
Half of the offspring have genetic material similar to the original cell.
Half of the offspring have physical characteristics similar to the original cell.
Which is an example of coevolution with the white-tipped sicklebill?
A snake species learns to climb trees to have an advantage in attacking the white-tipped sicklebill.
An insect species with a soft exoskeleton becomes extinct due the spread of the white-tipped sicklebill population.
A different species of hummingbird migrates north every summer and does not mate with the white-tipped sicklebill.
A plant species has a curve-shaped flower, causing the white-tipped sicklebill species to change to reach the nectar better.
Which molecule is responsible for bringing the amino acid to the ribosome during protein synthesis?
DNA
mRNA
rRNA
tRNA
Which action will occur if a checkpoint during a cell cycle finds that the DNA was unsuccessfully replicated?
The cell will divide quicker with less DNA.
The cell will grow proteins to replace DNA.
The cell will perform the cell cycle in reverse.
The cell will not complete the cell cycle.
How does natural selection improve a population?
The individual organisms that are best suited to the future environment survive, and their gene types increase in the population.
The individual organisms that are best adapted to the current environment survive, and their gene types increase in the population.
The individual organisms that are best suited to the previous environments are removed and cause the population size to decrease.
The individual organisms that are best suited to another environment are removed and the population size to decrease.
Which information can the fossils provide?
They show how a modern elephant would have looked millions of years ago.
They provide evidence of what structures are similar between the mastodon and elephant.
They provide detailed information on how the mastodon raised its young.
They show how an elephant would have attracted a mate in the past.
A researcher observes that a skin cell is dividing faster than the skin cells around it. What has most likely to cause the skin cell to divide quickly?
The cell has become a cancerous cell because it is not progressing like the cells around it.
The cell has become a stem cell because it is different from the cells around it.
The cell has differentiated into a new cell type because it is acting different than the cells around it.
The cell has evolved because it is behaving in a way that is unique to the cells around it.
Which a limitation in adult stem cell research?
It is difficult to obtain a large number of adult stem cells.
It is difficult to find uses for adult stem cells.
It is unlikely that an adult stem cell will differentiate.
It is unlikely that an adult stem cell will repair tissue.
