Adélie penguins are well adapted to Antarctica’s cold climate. They eat fish off the coast of Antarctica and build nests on land. The average temperature in Antarctica has been increasing. Scientists claim that if this trend continues, it may have a negative effect on the penguins’ ability to survive.
Melting ice will decrease the concentration of salt in the ocean.
Increasing ocean temperatures will reduce fish population sizes.
Increasing air temperatures will allow more plant species to grow.
Melting snow will increase the size of the area where the penguins live.
What is a control in an experiment?
An element that remains unchanged or unaffected by other variables.
A quantity that does not change.
What is science?
refers to the process of exploring new knowledge methodically through observation and experiments.
refers to the continuous process of implementing knowledge.
What is Quantitative Data?
Quantity, like number or measure

A cell in the leaf of a green plant performs both photosynthesis and cellular respiration, often at the same time. Which statement best describes how these processes are related to each other?
Both processes produce carbon dioxide.
Both processes require energy directly from the Sun.
Products of one process are used as some of the reactants for the other process.
Thermal energy from one process is used as the energy source for the other process.
Which statement best describes a relationship between mitochondria and chloroplasts?
Mitochondria release chemical energy from molecules and store it in chloroplasts.
Chloroplasts release chemical energy from molecules and store it in mitochondria.
Mitochondria convert chemical energy into light energy that can be used by chloroplasts.
Chloroplasts convert light energy into chemical energy that can be used by mitochondria.
Which process uses the products of photosynthesis as reactants?
Active transport
cellular respiration
DNA replication
protein synthesis
