Answer:

3.5 billion years ago, or in the Eoarchean Era.

Explanation:

The first known single-celled organisms appeared on Earth about 3.5 billion years ago, roughly a billion years after Earth formed. More complex forms of life took longer to evolve, with the first multicellular animals not appearing until about 600 million years ago.

The earliest undisputed evidence of life on Earth dates at least from 3.5 billion years ago, during the Eoarchean Era.

Explain why an organism cannot choose to have a mutation that would enable it to live more successfully in its environment.
vaieri [72.5K]

Answer:

Explanation:

An organism can't chose to have a mutation because it depends on the way they are born. If they are missing some type of mineral, (Protein, Vitamin, etc.) they will have a mutation because they're missing that. Well, something similar to a mutation is natural selection and genes. For example, there are some short and tall giraffes. The tall ones can reach the tree and the short ones can't so they die and the tall ones can reproduce and their offspring will inherit that trait

What is the relationship between the Kuiper Belt and the status of Pluto today?
pentagon [3]

The correct answer is B. The Kuiper Belt is home to a dwarf planet similar to Pluto

Explanation

The Kuiper Belt is the most remote area of the solar system, it is an elliptical region, which is more or less 149.5 million kilometers from the sun. Its name refers to the fact that it is a belt, so it could be associated with the appearance of the asteroid belt that is located between Mars and Jupiter. However, in the Kuiper Belt most objects are icy rather than rocky. In this region of the solar system you can find several dwarf planets such as Pluto, these planets are classified as such because their size is enough to be considered as or asteroids, but they cannot be considered planets either because they do not meet any requirement. According to the above, the correct answer is B. The Kuiper Belt is home to a dwarf planet similar to Pluto
