What will happen to the passengers sitting on a train if the train comes to a sudden stop?

Their organs will smash into their ribcage

Explanation:

they would be sent forward/ whatever direction the tarin was going.

Explanation:

let's say the train is moving 20 mph

Therefore everyone/ everything in the train is also moving 20 mph. If the train just went to 0 mph. everyone would still be going 20 mph.

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.

explanation:

the electromagnetic energy from the sun arrives in the form of visible and invisible light.
