B) The chart shows the percentages of elements in a compound. C) The chart shows the percentages of pure substances in a mixture. D) The chart shows the percentages of compounds in a pure substance.

Answers

Answer 1
Answer:

The approximate composition of the atmosphere is shown in the pie-chart shows the percentages of pure substances in a mixture.

Atmosphere:

It is a mixture of different gases around the earth. This includes Nitrogen, Oxygen, Carbon dioxide etc.

  • The constituent gases are not just elements some are compounds also such as Carbon dioxide.
  • Atmosphere is the mixture of gases.

Hence, options A, B, and D are incorrect.

Therefore, the approximate composition of the atmosphere is shown in the pie-chart shows the percentages of pure substances in a mixture.

All living organisms are made up of cells. Unicellular organisms are made up of only one cell. Multicellular organisms are made up of more than one cell. In which kingdoms are both unicellular and multicellular organisms found?

Answers

The kingdoms that consist of both unicellular and multicellular organisms are the Protists and Fungi.

What is Kingdom?

Kingdom may be defined as a type of taxonomic rank that is significantly composed of smaller groups called phyla. It is considered the second highest taxonomic rank, just below the domain.

Unicellular organisms are made up of only one cell while Multicellular organisms are made up of more than one cell. Protists and fungi are classified into eukaryotic cells which are complex and possess numerous cell organelles. Most of the protists are unicellular in nature such as Amoeba and Paramecium. Multicellular protists include diverse forms of algae and seaweed.

When it comes to fungi, most of them are multicellular such as mushrooms and molds. The unicellular forms of fungi are yeast.

Therefore, protists and fungi are the two kingdoms that consist of both unicellular and multicellular organisms.
