Answer:
I would say one or more cells.
Explanation:
Unicellular organisms like bacteria contain one cell.
A multicellular organism, like us humans, contain many cells.
Therefore, all other options can be ruled out as living things can have one cell, or many cells.
The greenhouse effect is necessary to explain
why weather occurs. The climate of the Earth is greatly affected by two
opposing processes: the greenhouse effect and atmospheric convection. The
greenhouse effect is acting to warm the lower atmosphere and cool the
upper atmosphere while the atmospheric convention (composed of thermals,
clouds, precipitation) is cooling the lower atmosphere and warms the upper
atmosphere). <span>The greenhouse effect warms the Earth’s surface, but very few people are
aware that weather processes greatly limit that warming.<span> In the absence of greenhouse effect, the Earth will
be left without weather.</span></span>
A species must be able capable of surviving and reproducing despite changes to food sources, climate, or threats from predators.
The time periods of the Paleozoic and Mesozoic are subdivided into early, middle, and late unlike in the Cenozoic because the number of fossils discovered outnumbers the quantity needed to subdivide the periods based on the presence of organisms.
<span>Early, middle and late time are geological times. Time periods were subdivided because of the major evolutionary events in the fossil record during the Paleozoic and Mesozoic era. </span>
Under Mesozoic:
<span>· </span>Cretaceous
<span>· </span>Jurassic and
<span>· </span>Triassic
Uner Paleozoic:
<span>· </span>Permian
<span>· </span>Carboniferous
<span>· </span>Devonian
<span>· </span>Silurian
<span>· </span>Ordovician and
<span>· </span>Cambrian
<span>While in Cenozoic we have the tertiary or mammals diversity only.</span>
