Which statement best describes an effect of humans on this food web?
the population of bald eagles may be reduced by humans consuming too many smelt.
Competition among humans, alewife, and smelt decreases food availability for bald eagles
Humans decrease the populations of phytoplankton and zooplankton by consuming chinook salmon

Look into the sky on a clear night and you may be able to observe the Moon, or part of it, lit up by the Sun. People can keep track of the Moon's appearance from Earth in lunar calendars. This makes it easy to see how the appearance of the Moon changes over time. A student made the following lunar calendar for 16 days, but it was cloudy on several nights.
A student is studying the partial lunar calendar. Which sequence of moon phases correctly represents the pattern in the appearance of the moon and completes the calendar?
The diagram below represents the saltwater solution made by the student. When salt (NaCl) molecules are added to water (H2O), they break into one sodium (Na) particle and one chlorine (Cl) particle.
Chose the name of the solvent and solute
Solute = H2O Solvent=NaCI
Solvent = H2O Solute= NaCl
A student needs to separate a mixture compsed of iron fillings and sand. How can the student most easily separate all the iron fillings from the mixture?
Use a magnet to attract the iron filings
Use filter paper to isolate the iron filings
Add water to the mixture and pour off the floating iron filings.
Add water to the mixture and allow it to evaporate and leave behind the iron filings
A student is identifying properties of chemical particles by using the chart below. Complete the chart by selecting boxes to identify each property as a description of an atom, a molecule, or both

Which statement identifies the most likely outcome if the rabbit population suddenly reduced?
Owls would become extinct because they have no food
Hawks would have less food available so their population would decrease
Grasshoppers would have less food available so their population would decrease
Grasses in the area would die and all of the animals would have to move to another area to survive
The diagram shows four blocks of the same size in a water tank. Block Y has the same density as the water.
Four additional block are being added to the water as detailed (Block J= 1kg) - (Block K =3 kg)- (Block L=5 kg)-(Block M=7kg)
Pick two answers choices - the two blocks that will float and two blocks that will sink.
BLOCK J & K WILL FLOAT
BLOCK J & K WILL SINK
BLOCK L & M WILL SINK
BLOCK L & M WILL FLOAT
