Answer:
Solid: State of matter with definite shape.
Gas: State of matter with particles very far apart.
1 or 3: Arrows that show particles getting closer together.
2 or 4: Arrows that show particles gaining energy.
Gas: State of matter that will fill any container.
Liquid: Sate of matter with definite volume but not shape.
Solid: State of mater with least amount of kinetic energy.
Explanation:
There are three states of matter :
Solid: It is the state in which atoms are tightly packed such that either they can make no movement at all or just can cause vibrations. Hence, solids have a definite shape and volume.
Liquids: When the solid molecules are heated, they gain energy and free themselves, converting into the liquid state. The molecules have a definite volume but not a definite shape.
Gas: When liquid molecules are heated together, they gain more energy and start hitting the walls of the container with a much greater space. They move more freely in this state and hence the molecules do not have a definite shape or volume in this state.
Answer:
This study examines genetic diversity among 102 registered English Bulldogs used for breeding based on maternal and paternal haplotypes, allele frequencies in 33 highly polymorphic short tandem repeat (STR) loci on 25 chromosomes, STR-linked dog leukocyte antigen (DLA) class
Explanation:
I think it is A most likely, but I may be incorrect.
It is important because it provides health to the earth and us so that the life cycle can keep running smoothly
