Answer:

A culture medium provides water, nutrients, and a place for waste products to be removed for a living cell.

Explanation:

Water is important for many cell processes and makes up a majority of the cell. Osmosis is the process of water moving in and out of the cell and is dependent on the concentration of water molecules. The cell membrane is a double layer of phospholipids that allow small molecules like water and gas to pass through but not larger molecules. The cell membrane also has protein channels that allow larger molecules to pass through.

Vikki [24]

<u>Answer</u>: The answers are matched as follows:

African forests have been hunted to near extinction levels to obtain ivory-------------->human exploitation

The eruption of mount Saint Helens destroyed some populations of conifers------> natural disasters

An infection with a fungus reduced the population of North American Elm trees ----> disease

Increasing global temperatures have altered migration patterns of humpback whales ------>climate change

<u>Explanation</u>:

  • <em>Human</em> <em>exploitation</em> is the unethical or selfish use of resources to satisfy their own personal needs or for any profitable activity which harms the resources in such a way that they get limited. Humans have been hunting elephants to obtain ivory for many purposes such as making jewellery etc. and earning profits from it. Due to such extensive hunting they have driven the elephants to a level of extinction and thus, this is a form of human exploitation.
  • Mount Saint Helens is a volcano and its eruption which harms the population of the trees in the area is a form of natural disaster since volcanic eruption is a <em>natural</em> <em>phenomena</em>.
  • Fungal infection is a <em>disease</em> which is cause by the microorganisms which harms the population of the Elm trees.
  • Increase of global temperature is a type of climate <em>change</em> and thus, this effect of alteration of migration pattern is caused by climate change.
