The basic ingredients used to make a thunderstorm are moisture, unstable air and lift.
Therefore it should be: A. A stationary front
Random mutations are the ultimate source<span> of </span>genetic<span> variation. Mutations are likely to be rare and most mutations are neutral or deleterious, but in some instances the new alleles can be favored by natural selection.</span>
Those fish species are removed/ weakened so the organisms that the fish eat have less natural predators and increase in population. They need to eat more kelp in order to sustain their population, resulting in a loss of kelp as there is suddenly more of a demand for it then the kelp can grow. All because the predators were removed from the food chain.
<em>An ever-growing demand for resources by a growing population</em> is putting tremendous pressures on our planet's biodiversity and is threatening our future security, health and well-being, reveals the 2012 edition of WWF's Living Planet Report – the leading biennial survey of the Earth's health.
The correct answer is D. Bacteria and archaea
Explanation:
In biology, cells can be mainly classified into prokaryotic and eukaryotic. The prokaryotic cells are cells with no nucleus or centrioles but they do have a cell wall, usually one chromosome and complex cilia and flagella. On the other hand, prokaryotic cells have a defined nucleus, multiple chromosomes, and centrioles and some have a cell wall. Due to the differences between these two type of cells they are part of different organisms, in the case of eukaryotic cells, these are part of the complex organism that includes animals, plants, and fungi while prokaryotic cells are those found in bacteria and archaea which are organisms with only one cell. Considering this, the ones that consist of prokaryotic cells are bacteria and archaea.
