Viruses do not have any cells or metabolism. Viruses cannot reproduce on their own.

Most scientists do not consider viruses to be living.

Bacteria and fungi have cells, metabolism, and are able to reproduce.

Bacteria are unicellular microorganisms that can be found everywhere in the environment. Viruses are microorganisms that can only reproduce within the cells of a host organism.

The differences between viruses and bacteria include;

Viruses do not have any cell and are considered between living and non-living things, while bacteria have one cell (Unicellular) and are living organisms.
Viruses are smaller in size (20-400 nm) when compared with bacteria (1000 nm).
Viruses do not have a cell wall but a protein coat is present, while bacteria have a cell wall that is composed of peptidoglycan.
Viruses require a living cell to reproduce, while bacteria can reproduce by itself.
The DNA or RNA of viruses is enclosed inside a coat of protein, while that of bacteria floats freely in the cytoplasm within the cell.

2. Can the classification system change? If so, provide an example of a way it has changed in the past. (2 points)

Elis [28]

Yes, classification system is still evolving together with our knowledge.

But, before changing the name (e.g. of a species) it is important to collect and gather a wealth of information in order to support that change. Classification system is still evolving. The reasons for the changes are DNA analyzes. It is the new way for discovering relation between organisms and put them in the right context (classification used to be based on morphological characteristics).

Change in classification can be shown in an example of fungi. In the 90s fungi classification included only phyla Chytridiomycota and Zygomycota. Now theyhave been classified mainly on the basis of characteristics of their sexual reproductive structures. So, there are 7 phyla now: Microsporidia, Chytridiomycota, Blastocladiomycota, Neocallimastigomycota, Glomeromycota, Ascomycota, and Basidiomycota

an igneous rock forms quickly. which characteristics could the rock have? small sand grains. Large mineral crystals. smooth, sha

Shalnov [3]

Igneous rocks are formed by hot melted magma coming from the Earth's core that crystalizes when gets in contact with air. They can be either intrusive or extrusive. B) <em>Large mineral crystals.</em>

<h3>What is the igneous rock?</h3>

These rocks come straight from the interior of the Earth.

A liquid mass of silicate composition comes from the Earth's core. This melted mass comes at an extremely high temperature.

Magma begins to cool and solidify during its ascent to the Earth's surface. It solidifies and crystallizes into igneous rock following the magnetic field orientation.

Thre are two types of igneous rocks

• plutonic rocks ⇒ in areas close to the terrestrial crust ⇒ intrusive

• volcanic rocks ⇒ on the surface ⇒ extrusive

According to this description, the correct option is B. <em>Large mineral </em><em>crystals</em><em>.</em>
