The fingerlike projections which line the small intestine increase the surface area to maximize absorption and help mix the partially digested chyme with intestinal secretions are:______

Answers

Answer 1
Answer:

Answer:

The correct answer is- Villi

Explanation:

Villi are the finger-like projection present in the highly folded surface of the intestine and line the intestine. Each villus has many microvilli which are microscopic projection on villi. These villi increase the surface area of the intestine because of having many folds. This increase in surface area helps in maximizing the nutrient absorption for the intestine.

It also helps in mixing the chyme with the intestinal secretion. The nutrient which is absorbed is then move to liver through the hepatic portal vein and then distributed in the body.

If you are part of a center or network, you can use program-level data to?

Answers

Answer:

Once your data center reaches a certain size, it is nearly impossible to accurately manage your data center infrastructure manually. Spreadsheets and Visio diagrams can’t cut it when it comes to tracking assets, power, space, cooling and network capacity. Leading data center professionals turn to software solutions referred to as Data Center Infrastructure Management (DCIM) to take control of their data center operations.

Dogs (Canis lupus familiaris) and gray wolves (Canis lupus) can interbreed to produce viable, fertile offspring. These species shared a common ancestor recently (in geologic time) and have a high degree of genetic similarity, although their anatomies vary widely. Judging from this evidence, which two species concepts are most likely to place dogs and wolves together into a single species?

Answers

Answer:

1. Biological Species Concept

2. Phylogenetic Species Concept

Explanation:

Ernst Mayr defined the species on the basis of the biological species concept. Accordingly, the organisms that are capable of interbreeding to produce fertile progeny belong to the same species.  

Since dogs and gray wolves are able to produce fertile progeny, they belong to the same species as per the biological species concept.  

According to the phylogenetic species concept, two organisms that share a recent common ancestor and exhibit certain derived traits, belong to the same species.

According to the given information, dogs and gray wolves are descended from a common ancestor and hence, belong to the same species according to the phylogenetic species concept.
