Agroup of ants escaped from a picnic basket carried to the top of a mountain and thrived in this area where there were no other ants. many years later descendants of these ants crawled into a picnic basket on the mountain and traveled back to the valley from which their ancestors had come. which of these observations would cause you to conclude that the ants on top of the mountain had become a different species from those in the valley? a group of ants escaped from a picnic basket carried to the top of a mountain and thrived in this area where there were no other ants. many years later descendants of these ants crawled into a picnic basket on the mountain and traveled back to the valley from which their ancestors had come. which of these observations would cause you to conclude that the ants on top of the mountain had become a different species from those in the valley? the mountain ants and valley ants were different colors. the mountain ants ate different food than the valley ants. the mountain ants could not mate with the valley ants.

Agroup of students is studying convection currents. they fill two identical balloons with the same amount of helium. one balloon is placed in a freezer and the other in an area with warm air. after 10 minutes, the balloons are released from a height of 1 meter. which of the following do the students most likely observe? question 8 options: the cold balloon expands and rises. the warm balloon shrinks and sinks. the balloons rise at the same rate. both balloons are the same size. the ballons both rise. the cold ballon is larger than the warm balloon. the warm balloon expands and rises. the cold balloon shrinks and sinks.

Is a measure of the resistance to flow. a high liquid has a high resistance to flow and flows slowly. the ancients thought everything in the world was made of 4 we now know that there are 94 naturally occurring and scientists have created another 24 i am certain they will create even more. honey flows slowly because it has a high to flowing. a can be separated by physical means because it contains more than one pure substance and 2 pure substances are not chemically bonded to each other. a cannot be separated by physical means. all matter is made up of all elements are with the same number of protons. if it is just a single or many bonded together, if all of them have the same number of protons, it is an element. in a piece of pure iron metal, all the are joined together, that piece of iron metal is called elemental iron. a single of iron is called elemental iron. a mixture has differences from place to place. we might need a microscope to see them or they might be obvious to the unaided eye. there are surfaces separating it into different phases. a mixture is the same everywhere. it is uniform. there are no surfaces separating it into different phases. if different kinds of atoms (different elements) are bonded together by their electrons, it is called a there are physical means of to isolate the different pure substances in a mixture and there are chemical means of to isolate the different elements in a compound. 1. element 2. compound 3. mixture 4. heterogeneous 5. homogeneous 6. pure substance 7. atoms 8. separation 9. viscosity 10. resistance
