Suppose a scientists found a new metal like substance in the dessert. he determined its mass to be 20 grams. the volume was determined by water displacement to be 5 cm3. what is the density of the substance? will it sink or float in liquid water (1g/cm3)?

airlines i think? or a cruise boat? does this work out for u? ?

idk im sorry.

i believe it's c. the trait for large beaks will be passed on to future generations through natural selection.

since eventually smaller beaks would have to find another source of food or even eventually just die out from the lack of food.
