Answer: Ambulatory monitoring of the electrocardiogram in 100 healthy 14 to 16 year old boys showed heart rates ranging from 45 to 200 beats/minute during the day and from 23 to 95 beats/minute during sleep.
The groups of plants are pteridophytes (ferns), Bryophytes (mosses) and lichens.
Algae is not a good answer since they live in an aquatic environment.
Plants without flowers (ferns, mosses, lichens) have neither flowers nor seeds. They can colonize various environments, terrestrial or aquatic. Ferns and mosses for example settle between the stones of an old well. The reproduction of plants without flowers is mainly due to spores.
The best action to take during a earth quake is to take cover, and move away from any building's, street light's, or any types of wires. Doing these thing's can save someone's life. Moving into an open area will keep rubble from falling on a person. Keeping away from wires is a great way to stay safe, in fact. Electrical wires don't shutdown, so if someone where to come in contact with wires, they might get shocked which can lead to death. Staying away from street lights can also save someone's life. During an earthquake, it's posisble that a street light can fall, if you are close to one a street light could lant on you causing serious breakage to your bones, or even death.
