A student at an exhibition looks at a model of Earth, as shown. The model is made using different colors to show water and land on the surface of Earth. The color green shows areas covered in land and blue shows areas covered in water. Each side of the model is shown.



The student learns that the water on Earth is stored in different forms. Water on Earth is broadly categorized into salt water and freshwater. The usability of water depends on the quantity available and its characteristics. The model shows the distribution of water on Earth in various reservoirs.

Question:The student claims there are large quantities of water immediately available for humans to drink on the surface of Earth. Is the claim given by the student correct? Use evidence from the graphs to describe why or why not.

Is the classification system of domains and kingdoms the only system that scientists have ever used to classify organisms?

Answers

No there are three distinct domination

No, the classification system of domains and kingdoms is not the only system that scientists have used to classify organisms.

What is a classification process?

The classification of living organisms has been a continuous process since the time of Aristotle, and scientists have used various systems over time to classify organisms.

Prior to the current system, scientists used a five-kingdom classification system that classified organisms into Monera, Protista, Fungi, Plantae, and Animalia. However, advances in molecular biology and genetics led to the realization that this system did not accurately reflect the evolutionary relationships among organisms.

The current classification system, which is based on three domains - Archaea, Bacteria, and Eukarya - was proposed in the late 1970s and early 1980s by Carl Woese and his colleagues.

A scientist observes two stars in the night sky through a telescope. Star A is white in color and relatively dim. The star’s estimated temperature is very high.

Star B is red in color and extremely bright. The star’s temperature is low compared with other stars.

Help the scientist classify the two stars.

Answers

Answer:

Star A is a Neutron Star while Star B is a Red Giant

Explanation: Neutron star is a very hot star, very small in size and hence dim and is white in color. A neutron star results after a massive star goes supernova. It is primarily composed of neutrons packed in a small boundary.

 star B would be a red giant. This is because, a red giant star is red in color, is very big in size, and has a low temperature. A red giant star is a towards the end stage of a small to an average mass star.

Star A is an white dwarf star
