What provides evidence of an increase in animal species at the same time that atmospheric oxygen concentrations increased?
12345 [234]

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.

Which of the following is not a component of the hepatic triad found at the edges of a liver lobule?
goldenfox [79]

Answer: c) central vein.

Explanation:

The liver is an organ that is present both in humans and in vertebrate animals. It secretes the bile, essential for the digestion of fats, and it also has many other functions, including the synthesis of plasma proteins, storage of vitamins and glycogen and detoxifying function. It is responsible for removing various substances from the blood that may be harmful to the body, including alcohol, making them harmless.

The liver is divided by the sickle cell ligament into two main lobes, right and left. <u>There are two other smaller lobes, the square lobe and the caudate lobe</u>.

The hepatic triads are triangular areas located at the angles of the hepatic lobules, made up of a lax conjunctive stroma. <u>They contain a branch of the hepatic artery</u> (that irrigates the liver<u>),</u> <u>a hepatic portail vein</u> (a thick blood vessel that carries blood from the gastrointestinal tract and spleen to the liver so that nutrients are metabolized<u>)</u> and <u>a bile duct</u> (transports bile into the small intestine). Therefore, it does not contain a central vein.
