Answer:
For the animal structure, see Down feather. Grass seedlings, 150-minute time lapse. Monocot (left) and dicot (right) seedlings. A seedling is a young plant sporophyte developing out of a plant embryo from a seed. Seedling They will open their cotyledons and turn green when treated with light.
Explanation:
B. Precipitation affects the rate at which nutrients are removed from soil.
Soil is known to be a loose mixture of rock fragments, water, organic materials and air that usually accommodate the growth of vegetation. Thus, formation and development of soil is a dynamic process rather than static and soil is present when pre-historic animals roamed the Earth and some these animals are preserved only fossilized soils buried deep beneath our present soil.
Answer:
Fossil records provide evidence of an increase in animal species at the same time that atmospheric oxygen levels increased.
Explanation:
A huge diversification among animal species occurred with the increase in the levels of atmospheric oxygen. The reason why the number of species increased drastically was that a whole new world opened up, the land. The land was open for exploitation and taking over, with every single niche free, so animals diversified and filled in pretty much all of the niches. The fossil records give us clues when this happened, as from only microorganisms there is a sharp rise in complex animals, coinciding with the increase of oxygen levels.
If it wasn't for the increase of atmospheric oxygen though this wouldn't have been possible. The oxygen in the atmosphere enabled animals to breathe on land. Also, it cooled off the global temperatures which were too high before the increase of atmospheric oxygen, making them suitable for life. And last but not least, the atmospheric oxygen resulted in the formation of the ozone layer, a layer that started to act as protection from the UV rays.
Well, scientists may have collected new information about their theory and had to revise said theory to keep it up to date. Does that help? :)
