A student wants to prove that amphibians appeared on earth before birds. The student should use the fossil findings as evidence to provide the most reliable information about the periods when amphibians and birds appeared on earth. Fossils would throw light on the internal body structures that bear the closest similarity to either the amphibians or the birds. The radiocarbon dating of the fossils will reveal its age. This can be used to figure out the time of divergence of the two types.
Answer:
El Niño is defined as an unusual weather pattern seen in the Pacific Ocean. In this weather unusual winds allows the surface water to get warm from the equator to move east, that is toward Central and South America.
So, El Niño affects wind shear, in which air current present in lower altitude moves to different direction from winds higher in the atmosphere and affects weather patterns. such as El Niño is responsble for more rain in South and Central America and in the United States.
This type of organism is called an autotroph.They are organisms capable of self-nourishment by using inorganic materials as a source of nutrients and using photosynthesis or chemosynthesis as a source of energy
