What provides evidence of an increase in animal species at the same time that atmospheric oxygen concentrations increased?ts fossil records but i need an explination

Answers

Answer 1

Answer:

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.

By which processes are rocks broken up and moved to different locations

Answers

Rocks are broken up and moved to different locations through the processes called Weathering and Erosion.

What are the different forms in which rocks changed to?

Igneous rock to Metamorphic rock to igneous rock, Sedimentary rock to metamorphic rock as in changing a rock through the listed processes heat is highly required.

Transformation from a rock to igneous rocks requires the most heat because the rock body must be molten. In moving from metamorphic to igneous rock, the melting temperature of a rock must be attained in order for magma to form and sedimentary changes to metamorphic rocks also require heat.

Igneous rock to metamorphic rock is a metamorphic change that requires significant heat and pressure. The mineralogical fabric is affected by this change.

Therefore, Rocks are broken up and moved to different locations through the processes called Weathering and Erosion.

Three species of North American warblers are found to feed in different parts of the same spruce tree. This particular behavior of warblers displays which ecological characteristic?

Answers

In this particular behavior, the three species of North American warblers cannot share the same niche in the same habitat. It is called "Gause's Competitive Exclusion Principle." It means the competitors with equal bearing cannot exist. There will always be the dominant one in a competition.

Why are frogs said to have 2 lives

Answers

Amphibian means two-lives, Frogs began there lives in the water as eggs and then grow to tadpoles, when they are fully developed they live on land.

they start their life in water as a tadpole then they adapt to land and go through metamorphosis to become a frog

A plant with the genotype TT is called _____.

homozygous
heterozygous
hybrid

Answers

If a genotype has two of the same alleles, as in two capital letters (two dominant alleles) or two lowercase letters (two recessive alleles), it is homozygous. If it was Tt, had one recessive allele and one dominant allele, it would be heterozygous.

When an individual has two of the same allele, whether dominant or recessive, they are homozygous.
so the answer is homozygous :)))

Which of the following happens first?A)Introns are edited out of the premature DNA.
B)RNA ploymerase reaches a terminator region.
C)Nucleotides are covalently linked together.
D) RNA polymerase binds to a promoter region of DNA.

Answers

In transcription, the enzyme that makes the RNA transcript must bind to the promoter region of the DNA before it starts making an RNA transcript. RNA nucleotides will be covalently linked together as the RNA transcript is made. The RNA transcript (also known as pre-mRNA) will be completed when the RNA polymerase reaches the terminator region. After the RNA transcript is released from the RNA polymerase, it will undergo several steps of processing, one of which involves the removal of introns
