A tapeworm lives in human intestines, absorbing the nutrients that would normally be absorbed by the person. This eventually causes the person health problems. The relationship between the tapeworm and the human is -
parasite/host
predator/prey
herbivore/omnivore/omnivore
consumer/producer
Which organelle functions as a place to store extra water?
Vacoule
Chloroplasts
Nucleus
Cell membrane
DNA is essential to living organisms because it---
carries the genetic code
is a spiral helix
can prevent diseases
can break apart
What is the greenhouse effect?
It keeps the earth moving on its axis
When the sun is out its much warmer than when it is not.
The reflecting and absorbing of energy from the Sun
Water vapor, carbon dioxide and other gasses help to trap the solar energy and keep it for life on earth
What would you predict would happen if there is a shortage of incoming solar energy?
Less solar energy would produce higher air and water temperatures.
Less solar energy would cause overgrowth of plants.
Less solar energy would produce cooler air and water temperatures.
In which layer of the atmosphere do organisms live?
Troposphere
Thermosphere
Mesosphere
Stratosphere
Clouds are formed when millions of drops of water become suspended in the air. Which of the following is a step in the process of cloud formation?
Expansion of cold air.
Formation of carbon dioxide.
Condensation of water vapor.
Breakdown of atmospheric ozone.
Energy from the Sun is distributed around Earth by −
subduction and rift zones.
radiation and convection.
tectonic plates.
solar flares.
Which of the following might happen if precipitation increased within the watershed boundary?
Some wetlands would disappear.
Floodplains would dry out.
Water levels would rise in tributaries, streams, and the water table.
All of the following.
Why is the ozone layer so important?
Because it refracts most of the sun's heat.
Because it contains most of the earth's oxygen.
Because it blocks harmful ultraviolet rays.
Because it allows electromagnetic radiation to warm the thermosphere.
What is the role of chlorophyll in photosynthesis?
It absorbs sunlight to convert carbon dioxide and water into glucose.
It provides energy for cellular respiration.
It transports water from roots to leaves.
It protects the plant from herbivores.
Which of the following best describes the process of evaporation?
The change of state from liquid to gas.
The change of state from gas to liquid.
The change of state from solid to liquid.
The change of state from solid to gas.
What is the primary function of the roots in a plant?
To absorb water and nutrients from the soil.
To produce food through photosynthesis.
To support the plant above ground.
To transport nutrients to the leaves.
Which of the following is an example of a chemical change?
Melting of ice.
Boiling of water.
Rusting of iron.
Breaking of glass.
What is the main purpose of the scientific method?
To prove a hypothesis is correct.
To systematically investigate and understand phenomena.
To record data accurately.
To ensure experiments are conducted quickly.
