Four students described the characteristics of four different states of matter. the table below shows the description given by each student. which student described liquids? a) student a b) student b c) student c d) student d

Option (A) is the correct answer.

Explanation:

In solids, particles are attracted towards each other by strong intermolecular forces and they do not have enough gap between them. Therefore, they are orderly arranged.

In liquids, though the particles are close and touch each other but there are gaps between their arrangement. Therefore, they are randomly arranged as the forces of attraction are not strong enough like in solids.

In gases, particles are weakly attracted towards each other and they constantly moves from one place to another.

In plasma, there are charged particles which have similar number of positively charged ions and negatively charged electrons.

Thus, we can conclude that out of the given options, student A described liquids.

fertilization, pictured in figure 24.23a is the process in which gametes (an egg and sperm) fuse to form a zygote. the egg and sperm each contain one set of chromosomes. to ensure that the offspring has only one complete diploid set of chromosomes, only one sperm must fuse with one egg. in mammals, the egg is protected by a layer of extracellular matrix consisting mainly of glycoproteins called the zona pellucida. when a sperm binds to the zona pellucida, a series of biochemical events, called the acrosomal reactions, take place. in placental mammals, the acrosome contains digestive enzymes that initiate the degradation of the glycoprotein matrix protecting the egg and allowing the sperm plasma membrane to fuse with the egg plasma membrane, as illustrated in figure 24.23b. the fusion of these two membranes creates an opening through which the sperm nucleus is transferred into the ovum. the nuclear membranes of the egg and sperm break down and the two haploid genomes condense to form a diploid genome.

helicase, i think thats it
