Answer: A). bacteria

The first living cells to evolve on earth were single celled bacteria. These single celled organisms developed specialized structures to trap sunlight energy and to carry out photosynthesis e.g mitochondria, chloroplasts and lead to the development of multicellular organisms known as plants which are included in eukaryotes. All these changes have been found in fossil records of primitive organisms.

The first living things on Earth, single-celled micro-organisms or microbes lacking a cell nucleus or cell membrane known as prokaryotes, seem to have first appeared on Earth almost four billion years ago, just a few hundred million years after the formation of the Earth itself.

Briefly explain what properties of the atoms in water (H2O) give water the ability to form hydrogen bonds. Your answer should in
Serggg [28]

Answer:

Water molecules are polar, so they outline hydrogen bonds. This gives water great properties, such as a for the most part high bubbling or boiling point, tall specific warm, cohesion, grasp, and thickness. Hydrogen has an electronegativity of 2.0, though oxygen has an electronegativity of 3.5. The refinement in electronegativities is 1.5, which infers that water can be a polar covalent molecule. In water, an electron from each of the hydrogen particles is drawn towards the oxygen particle. Protons, as unequivocally charged hydrogen particles, move outstandingly rapidly in water from one water molecule to the taking after, which is why the conductivity of water is modestly tall.
