Ozark cavefish are small, colorless, blind fish that live in caves in southwest Missouri. The label indicates the lateral line in an Ozark cavefish. The lateral line is a system of sense organs used to detect movement, pressure, and vibration.

by improving their overall speed
by allowing for a larger body size

by providing them camouflage to evade predators
The table shows the amount of energy stored in each molecule in the photosynthesis reaction. Use the data to answer the question.
Which statement correctly describes the flow of energy in photosynthesis?
Photosynthesis releases energy when the reactants rearrange and form the bonds in the products
Photosynthesis releases energy when carbon dioxide and water combine to form glucose molecules
Photosynthesis stores energy because more energy is stored in glucose than it is in carbon dioxide and water
Photosynthesis stores energy because energy is released when glucose is formed from carbon dioxide and water.
The passage describes a condition that is inherited. Select ALL statements which lead scientist to believe the condition is genetically-controlled.
The condition is caused by *a mutation that changes a protein that affects the connective tissues. Connective tissues help the body grow and develop properly. The mutation can cause abnormal growth of bones, abnormalities in the heart, and problems with vision. A hypothesis exists that Abraham Lincoln had this condition. Lincoln was unusually tall, *had long limbs, and other physical features characteristic of the condition. Some researchers have speculated that Lincoln's mother died young from complication of this condition. In 1960, *a male descendant of Lincoln's great-great-grandfather was positively identified having this condition. Experts believe that nearly half of the people who have the condition do not know they have it, but *there are treatments available for people diagnosed with this condition.

If the drought continued what is a reasonable expectation for the distribution of beak depths in the bird species?
One hundred percent of the population will have a beak depth of 10.5 mm instead of 10.0mm
Sixteen percent of the population will have a beak depth of 9 mm instead of only 4% of the population with 9mm
Ten percent of the population will have a beak depth of 9 mm and 16% will of the population will have a beak depth
Sixteen percent of the population will have a beak depth of 10 mm and 3% of the population will have a beak depth of 9mm.
Which explanation describes the predicted pattern of beak change due to the continued drought?
Dry conditions will cause the extinction of smaller beaked birds and therefore a new species of birds will arise in the environment
Dry conditions do not appear to favor birds of any particular beak depth and therefore the populations will hove equally around the mean beak depth
Dry conditions favor birds with larger beak depths so the proportion of the population with larger beak depths will increase and smaller beak depths will descrease
Dry conditions favor birds with smaller beak depths, which will reproduce with greater frequency and increase the proportion of smaller beak depths within the population.
Why does DNA replication occur before mitosis and cell division?
DNA replication produces an extra copy of DNA to make sure each of the 2 daughter cells has it's own full-set of DNA before cell division takes place
DNA replication lengthens the DNA which separates during mitosis making sure each cell receives DNA before cell division
DNA replication is not necessary for mitosis and only happens in meiosis II before cell division to make sure there is enough DNA for the 4 daughter cells
DNA replication makes four strands of DNA to make sure each daughter cell has double the amount of DNA so the cells can go through cell division twice
Which claim is best supported by the data?
As annual precipitation increases, the population of Species A and B increase
As annual precipitation increases, the population of Species A and B decrease
As annual precipitation increases, the population of Species A increases while B decreases
As annual precipitation increases, the population of Species A decreases while B increases
If the precipitation levels observed in year '09 remain the same and resources remain constant, what can be predicted to occur with the population of Species B over the next 6 years?
Species B will continue to increase because historically the population has been increasing
Species B will stay around carrying capacity because the conditions are remaining constant, and not increasing or decreasing
Species B will decrease because they have used all of their resources and the population cannot be sustained

Individual rabbits will grow longer ears during their lifetimes and pass these traits on to their offspring
Individual rabbits will acquire other adaptions during their lifetimes and pass these traits on to their offspring

Which best explains why sea otters are less likely than harbor seals to maintain homeostasis after an oil spill?

Oil penetrates the air pockets in sea otters' fur which interferes with their ability to be buoyant and stay above the water line
A student walks to school in the morning when the outside temperature is 60 degrees. When the same student walks home after school, the outside temperature has dropped to 35 degrees. In this situation, how is thermal homeostasis maintained?

Why are atmospheric carbon dioxide levels rising, but total carbon levels are remaining the same?
Atmospheric carbon dioxide levels are rising, but total carbon levels are remaining the same because more carbon dioxide is being put into the air from respiration and combustion than photosynthesis can take out.
Atmospheric carbon dioxide levels are rising, but total carbon levels are remaining the same because photosynthesis, respiration, and combustion keep putting it up in the atmosphere
Atmospheric carbon dioxide levels are rising, but total carbon levels are remaining the same because the sun super heats the earth causing more global climate change
Atmospheric carbon dioxide levels are rising, but total carbon levels are remaining the same because chemical sinks in the atmosphere are abosrbing it.
