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.

Answer:
carries food produced by leaves
Explanation:
The diagram is a cross section of stem of a dicot plant, specifically <em>Hypericum perforatum</em>. It shows all the structures present in the stem like xylem, phloem, pith, cortex etc. The structure labelled X is phloem. It is present between xylem (stained red) and peripheral cortex. Phloem is responsible for conduction of sugars and nutrients in the plant thus it carries the food produced by leaves. Together xylem and phloem make the vascular tissue which surrounds the central pith (stained bluish-green).
<span>Carbon monoxide is a highly poisonous, odorless, colorless, and tasteless gas. It is very flammable in air over a wide range of concentrations (George 2001) and burns in air with a bright blue flame (O'Neil et al. 2006). It becomes a liquid at 81.62 K (-191.53 °C) and is insoluble in water above 70 °C (George 2001).</span>
