60 Trees have oak wilt
80 Trees have oak wilt
An insect called the hemlock woolly adelgid was introduced to a Virginia forest ecosystem. This pest feeds on the nutrients stored inside a hemlock tree, resulting in the death of the tree. Which kind of data would best help a student evaluate the effect of this insect?
A comparison of the adelgid with native pest species
An account of how the adelgid was introduced to Virginia ecosystems
A list of the foreign ecosystems infiltrated by the hemlock woolly adelgid
Information about the ecosystem's characteristics before the adelgid infestation
A student wanted to compare the transpiration rates of two different plant species at varying levels of humidity. Each plant was given the same amount of water and light. Which procedure should have been performed to prevent error in this investigation?
One type of plant should have been tested
Fewer plants should have been included in each group
The percent humidity should have been kept constant
Both groups should have been tested in the same soil type at each humidity level
Medicines are being produces using recombinant DNA technology. For veterinarians, the use of the DNA technology will result in--
a decreasing number of antibodies produced by pets
altering the chromosomes of healthy pets
making more treatments available for pets
identifying new diseases spread by pets
The jackrabbit is a desert animal. The jackrabbit's circulatory system increases blood flow to the ears during hot days. The blood flow to the ears decreases during cool or cold nights. This circulation pattern is most directly related to--
detoxification
excretion
osmosis
homeostasis
Proteins are among the most diverse group of macromolecules because of the--
different amino acids that can be connected in many sequences
different types of bonds linking amino acids together
energy phosphate groups that the amino acids contain
link between DNA base and amino acid in protein
The structural differences between a tadpole and an adult frog are due to the--
availability of food sources at different stages
type of DNA present at each developmental stage
Combination of genetic material inherited during fertilization
different sets of genes expressed at each stage of development
After 24 hours, the amount of gas that accumulated at the top of the inverted test tube is measured. The students conclude that the light source is causing the water to evaporate, causing water vapor to fill up the top of the tube. The best alternative explanation of these differences is that the--
gravity increased the downward flow of the trapped water
metabolism of the elodea plants absorbed CO2 from the water
heat from the light source caused the escape of dissolved gas
light caused the elodea plants to photosynthesize, releasing O2 gas
