<span>Phosphorus is not abundant in the atmosphere. It comes mostly from the land and ocean. Phosphorus cycle through the lithosphere, hydrosphere, and biosphere, but not the atmosphere. The reason for this is that phosphorus cannot be found in the gas state, unlike the sulfur. On the other hand, sulfur cycle partially occurs in the atmosphere.</span>
Answer:
<em>This is an example of natural selection (adaptation).</em>
Explanation:
Natural selection tends to favor those organisms which are better adapted to live in an environment.
As tortoises having flat shell and long neck were better adapted to live in barren area, hence through natural selection those organisms were favored in such an ecosystem.
As tortoises that lived on the vegetative lands were more adapted to live in such an ecosystem, hence through natural ecosystem these organisms were favored and increased in numbers.

<h3><u>Answer;</u></h3>

<h3><u>
Explanation;</u></h3>
- DNA is a type of nucleic acid that contains two long, twisted strands, known as double helix, that contain complementary genetic information.
- A gene is a segment of DNA that is passed down from parents to children and confers a trait to the offspring.
- The traits an organism displays are ultimately determined by the genes it inherited from its parents, known as genotype.
- Our understanding of DNA and inherited traits has changed over time since it has been continuously developed by many scientists over may decades.
