Intermolecular attraction describes how the particles that make up matter are attracted to each other. The graph below compares
the intermolecular attractions in two substances. One substance is a solid and the other is a liquid. *Pic*
Which statement best describes the two substances?
A) Particles are closer together in solids, therefore Substance B is a solid.
B) Particles are farther apart in solids, therefore Substance A is a solid.
C) Particles are closer together in liquids, therefore Substance A is a liquid.
D) Particles are farther apart in liquids, therefore Substance B is a liquid.
The correct answer is that ferns have two part in their life cycle: Diploid phase and haploid phase
The life cycle of a fern has two parts: sporophyte stage and gametophyte stage. The gametophyte stage of ferns are haploid which releases gametes and the sporophyte stage are diploid that produces spores. This kind of life cycle is known as the "alternation of generation".
