Answer:

Formation. When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle and a solid crust.

Answer:

<em>The correct option is B) the total variety of organisms on Earth</em>

Explanation:

Biodiversity can be described as the diversity or variety of life present on Earth. The variety of plants and animals which are located in different habitats make up the biodiversity. Biodiversity is the reason that different variety exist between members of a species. Biodiversity tends to favour those organisms which are better adapted to live in an environment. These organisms tend to pass on their characteristics to their offsprings and become more in number.

Explanation:

<u>a. The genes in the DNA instruct the cell to make proteins.</u>

Genes are a set of coded instructions in the form of DNA, which are crucial to cell regulation - these enable protein synthesis.

Further Explanation:

Nucleic acids are comprised of smaller units called nucleotides and function as storage for the body’s genetic information. These monomers include ribonucleic acid (RNA) or deoxyribonucleic acid (DNA). They differ from other macromolecules since they don’t provide the body with energy. They exist solely to encode and carry out protein synthesis.

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is condensed and tightly wound around histones as chromosomes. Chromosomes within the nucleus is unwound, unzipped and read by enzymes in a complex series of steps known as transcription. The message on DNA, called genes is copied by RNA polymerase, to form mRNA complementary sequence to that of the DNA strand. These are then translated into proteins in ribosomes.
