Questions 25

Answers

1
Which sources of light have been found to be collections of billions of stars?
galaxies
comets
constellations
meteors
2
What is the outcome variable in this experiment?
the number of bubbles produced by the plant
amount of time the bubbles were counted
distance of the light from the plant
type of plant in the beaker
3
What is the main function of the skeletal system connected with the muscular system?
to assist muscles in growth and development
to provide attachment points for muscles
to produce muscle cells inside the bone marrow
to produce enzymes that help muscles repair themselves
4
The fundamental reason that convection happens is because of
density
forces
conduction
acceleration
5
Which statement best summarizes the development of the atomic theory over time?
discovery of new evidence resulted in changes to the theory
as new elements were discovered the theory was modified
changes in the theory show that it's based on opinion
advancements in atomic models proved the theory correct
6
Which describes what happens to an object with the forces remaining balanced?
speed and direction will both change
speed and direction will remain constant
speed will stay constant, direction will change
speed will change, direction will stay constant
7
Why do we see lightning before we hear thunder?
sound travels slower than light
sound needs a medium to travel through
sound is not processed by the brain as fast as light
sound cannot reflect off surfaces as easily as light
8
In which layer of Earth do convection currents result in tectonic plate movement?
Mantle
Crust
Inner Core
Outer Core
9
What is the purpose of a decomposer in a food web?
to provide food for secondary consumers
to recycle nutrients into soil
to compete with secondary consumers for oxygen
to covert solar energy into food
10
Which process is the main source of atmospheric movement?
conduction
radiation
convection
11
Our current solar system is _________________.
heliocentric
planetcentric
geocentric
starcentric
12
Water level at the beach changes during the day. Why?
Earth's magnetic field
Earth's revolution
Moon's rotation
Moon's gravitational pull
13
Eating well-balanced meals gives you more energy to run. What energy transformation is this?
heat energy to mechanical
thermodynamic to dynamic
mechanical to electrical
chemical to mechanical
14
Why are stars different colors?
stars are at different stages of their life cycles
stars have different numbers of planets orbiting them
stars are in different galaxies
stars are different distances away
15
Which graph shows a person driving further away from their house at a constant speed?
H
G
F
I
16
Lithium and Sodium are in same group on the periodic table. What does this mean?
They have the same number of protons.
They react with each other.
They are the same size.
They have similar properties.
17
Deforestation would have what impact on the environment?
colder temperatures
increased erosion
excess ground moisture
greater oxygen production
18
Where does the replication of mutated genes occur in the human cell?
cell membrane
ribosome
nucleus
endoplasmic reticulum
19
Which statement shows climate instead of weather?
The rains next week are expected to cause flooding.
There should be heavy rains tomorrow.
The high temperature on Sept 4, 2009 was 32°C
The average temperature from 1930-1996 was 23°C
20
Which characteristic is most similar among our planets in our solar system?
mass
shape of orbit
chemical composition
number of satellites
21
What is the purpose of wearing a seat belt in the car?
to continue the motion
to accelerate the force
to continue the forward force
to counteract inertia
22
Which is an example of an interaction between the cryosphere and hydrosphere?
evaporation of water from oceans at the equator
release of fresh water into ocean water as icebergs melt
decomposition of organic matter at the bottom of the ocean
release of salt from icebergs into the ocean
23
How does the water cycle influence the rock cycle?
sudden evaporation of water removes moisture from rocks
decrease in rainfall makes the rocks hard and brittle
large amounts of water increase weathering and erosion
too much rain soaking into the ground makes new rocks
24
Which aspect of fossil fuels encourages scientists to find other sources of energy production?
they store energy for a short period of time
it takes a long time for them to form
the formation of fossil fuels results in pollution
inadequate organic material exists to replace fossil fuels
25
Why would scientists most likely perform the same experiment?
to see if the experiment is less expensive somewhere else
to confirm the results of the experiment
to verify that the hypothesis is a scientific law
to find out if weather affects the results
