The picture above shows a flask of hot water. This test was carried out to find out which type of container would hold heat the longest. Which of these graphs bests shows all of the data from this experiment?
Which of these best shows a change from solar energy to chemical energy?
Evaporation of water
Heating of pavement
Photosynthesis in leaves
Formation of rainbows
Animals and plants get their food in different ways. Animals usually ingest their food, while plants must produce their own food. The process through which plants produce their food is called
respiration
photosynthesis
pollination
germination
An open-air waste water treatment plant is flooded by rain. The rainwater and the waste run into a nearby creek. The organic wastes are very high in Biological Oxidation Demand (BOD) which means the bacteria in the waste need a lot of oxygen. What is the best hypothesis to explain why many fish might die as a result of this event?
The bacteria remove the oxygen from the water.
The bacteria create toxic wastes.
The bacteria are eaten by the fish and are toxic.
The bacteria eat all the food in the creek.
Which type of characteristics can be inherited?
Those controlled by genes
Those caused by accidents
Those produced by exercise
Those produced by diet
When animals hibernate, their heart rate and respiration decrease and they lose consciousness. Why do some animals hibernate?
To increase their body fat during cold periods
To conserve energy usage during the winter
To give their fur time to grow longer and thicker
To rest after a summer of high activity
According to the scale shown above, what is the approximate length of the baby blue whale?
2 meters
4 meters
6 meters
10 meters
Compounds are made up of more than one element. Which of the following represents a compound?
H2
NH3
O3
N2
Which of these would be different for an object if measured on the Earth and on the moon?
Mass
Weight
Volume
Density
The island of Guam had no native snake species until the brown tree snake was introduced. What effect did this egg-eating snake have on the native bird populations?
Bird populations were not affected by the snake's introduction
Bird populations increase as the birds preyed on the snakes
Bird populations decreased as the snakes fed on the bird eggs
Bird populations increased as the snakes eliminated predators
Which of the following elements has 16 protons?
Oxygen
Chlorine
Sulfur
Germanium
A student conducted an experiment on plant growth that required adding about one cupful of liquid fertilizer to several plants each week. In order to accurately measure the fertilizer given to each plant, the fertilizer volume should be measured in -
cubic meters
milliliters
cubic feet
kiloliters
An example of kinetic energy continuously being changed to potential energy and back again might be -
a girl swinging on a swing
a train moving down a track
electric charges moving in a straight path
a plate sitting on the edge of a table
The distance between one point on a compression and the corresponding point on the next compression in a sound wave is called a -
wavelength
rarefaction
crest
trough
Northern garter snakes exhibit a unique behavior in which they gather in deep dens by the hundreds or thousands. They then coil together in a huge ball. This behavior could help to -
reduce heat loss
increase camouflage
locate food sources
increase oxygen consumption
Which picture illustrates the structure of a molecule of water?
Which of these species would be most in danger of becoming extinct if one of their food sources became unavailable?
Brown bear
Panda
Polar bear
Black bear
This chart represents the type and number of items collected in a beach cleanup. Based on the above chart, what percentage of the total items collected from the beaches was plastic?
46%
49%
56%
70%
The sea urchin shown has radial symmetry. This means that its body parts are -
equally arranged around a central point
designed to function in seawater
likely to be reformed if any part of the body is damaged
able to function on land and in the water
What most likely happened to species that are found in the fossil record but have no living members?
They had offspring of a different species.
They mutated to other species.
They became extinct.
They never really existed.
The diagram above shows a block from the periodic table. The number six represents the -
atomic mass of the element carbon
atomic number of the element carbon
number of neutrons in the element carbon
number of valence electrons in the element carbon
A burning candle is in the process of transforming -
heat energy into chemical energy
chemical energy into light and heat
chemical energy into mechanical energy
chemical energy into nuclear energy
During which phase does the Moon receive sunlight only on the side facing away from Earth?
Full Moon
New Moon
Waning gibbous
Waxing gibbous
Which of the following best describes why the Moon orbits Earth?
The distance the Moon and Earth are from the Sun
The energy reflected from the surface of Earth
The winds generated on Earth by the energy of the Sun
The gravitational attraction between the Moon and Earth
Laundry in a clothes dryer often becomes charged with static electricity while drying. Which of these best explains why a clothes dryer often generates static electricity?
Short circuits in the dryer charge the laundry
Clothes with metal pieces conduct electricity in the dryer
Electrons are transferred as clothes rub against each other in the dryer
Heat from the dryer charges the air and produces lightning

Estuary
Ocean
Lake
Pond
Which of these uses sound waves to measure the distance between objects underwater?
Radar
Sonar

Slug
Centipede
Ant
Bacteria
Nuclear power plants can produce energy more cheaply and with less pollution than plants that use fossil fuels. Why are there not more nuclear power plants than plants that burn fossil fuels?
There is an endless supply of fossil fuels available.
Nuclear fuels produce too little heat during the fission reaction.
A pound of a fossil fuel produces more energy than a pound of nuclear fuel.
The problem of disposing large amounts of nuclear waste is not resolved.
In this atomic model, point A represents -
a proton
a nucleus
a neutron
an electron
