Answer:
The correct answer is option 2. "Scientists use seismometers to measure the earthquake activity that occurs beneath a volcano. They then predict the eruption of that volcano".
Explanation:
A seismometer is an equipment used by scientists to monitor ground's motion, including the earthquake activity that occurs beneath a volcano. These instruments are useful to predict if a volcanic eruption is imminent. By analyzing the length and strength of the ground's motion occurring during earthquake activity near a volcano, scientist could predict if an eruption is about to take place.
Answer:
All plants and animals on earth engage in a process called respiration. Respiration combines oxygen and the food created during photosynthesis to produce usable energy. One of the byproducts of respiration is CO2, this is the opposite of photosynthesis. It is not unusual for plants to stop taking in carbon dioxide to uptake small amounts of oxygen at night.
In the event that plants cease to take up CO2 all together, they will cease to convert sunlight into carbohydrates, and die. The death of autotrophs would lead to a chain reaction of the death of all higher order organisms. Mankind could survive on food stuffs on hand, but only for a very short time. It has been said that any western society, its members are just 3 meals away from revolution.
Social order would be completely lost during the initial food riots. Once the processed and packaged food supply is exhausted, it would be the law of the dying jungle. The strong and well armed would take from the weak and ill prepared. Livestock and game would be slaughtered as the next to the last food source disappeared. The shear volume of death would foul the water spreading pestilence and disease. In one or two years bands of humans would prey on other humans as they degenerate into cannibalism. There could be a few humans in protected bunkers and hideaways, but they too would eventually succumb to starvation or despair as the world died.
The fact that plants stopped converting CO2 into O2 would be of little consequence. Man would die of hunger 1000 years before oxygen was ever an issue.
The rapid speciation of mammals as a result of the availability of new habitat due to the extinction of the dinosaurs 65 million years ago is an example of adaptive radiation.
The correct answer is option 1, that is, there is an evolutionary link between the classes.
The study of one kind of proof of evolution is known as embryology, that is, the study of embryos. An embryo refers to an unborn young in its initial stages. Embryos of various distinct types of animals, that is, mammals, reptiles, birds, fishes, etc. seems very identical and it usually becomes tough to differentiate them apart.
Various traits of one kind of animal are observed in the embryo of another kind of animal. This illustrates that the animals are identical and that they are developed identically, signifying that they are associated, have common descendants and that they began the similar, slowly developing distinct traits, however, the fundamental plan for the beginning of the creature remains similar.
