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:

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.

Biology homework please help

Answers

Answer:

muscles

ribs

lungs

bronchioles

alveoli

diffuses

leaves

exchange

Explanation:

Your diaphragm, and muscles between your ribs, make air move in and out of your lungs. It travels through the trachea, bronchi, and bronchioles to alveoli. In the alveoli, oxygen diffuses into the blood and carbon dioxide leaves. This is gas exchange.

Air enters the lungs and leaves it as a result of the relaxation and contraction of the diaphragm and the muscles between the ribs. When both the muscles and the diaphragm relax, air enters from the trachea and travels through the bronchi and the bronchioles to the alveoli, where the oxygen in the air diffuses into the blood and carbon dioxide diffuse in the opposite direction. The entire process is known as gas exchange.

Which macromolecule is needed for lactic acid formation and alcohol fermentation to proceed with their processes?


IN YOUR OWN WORDS
DONT COPY FROM THE INTERNET

Answers

Answer:

sugar

Explanation:

sugar is the required macromolecule

In the lactic acid formation, pyruvate changes to the lactose which is the anaerobic form of respiration. Pyruvate changes to alcohol and carbon dioxide.

What is the main ingredient for lactic acid fermentation ?

It is the sugar molecule that is needed for the lactic acid fermentation.

Both the  types of  the fermentation requires two primary components which are a sugar supply and  bacterial culture where alcohol fermentation uses the  forms of  the yeast where the lactic acid fermentation usually depends on  the lactic acid bacteria.

Lactic acid fermentation takes place in some of the  strains of  the bacteria and in  the even skeletal muscle and even  produces lactic acid . Alcoholic fermentation takes place in the  yeast and just  produces ethanol with carbon dioxide.

Lactic acid bacteria is a type of gram-+ve bacteria which use carbohydrates as only and main carbon source. Later on lactic acid bacteria is generally cocci or rods usually have the  strong tolerance to low pH.
