Que características poseen los babuinos que no poseen los Lemures

Answers

Answer:

Opposing thumbs, expressive faces, complex social systems: it's hard to miss the similarities between apes and humans. Now a new study with a troop of zoo baboons and lots of peanuts shows that a less obvious trait -- the ability to understand numbers -- also is shared by humans and their primate cousins.

"The human capacity for complex symbolic math is clearly unique to our species," says co-author Jessica Cantlon, assistant professor of brain and cognitive sciences at the University of Rochester. "But where did this numeric prowess come from? In this study we've shown that non-human primates also possess basic quantitative abilities. In fact, non-human primates can be as accurate at discriminating between different quantities as a human child."

"This tells us that non-human primates have in common with humans a fundamental ability to make approximate quantity judgments," says Cantlon. "Humans build on this talent by learning number words and developing a linguistic system of numbers, but in the absence of language and counting, complex math abilities do still exist."

Cantlon, her research assistant Allison Barnard, postdoctoral fellow Kelly Hughes, and other colleagues at the University of Rochester and the Seneca Park Zoo in Rochester, N.Y., reported their findings online May 2 in the open-access journal Frontiers in Comparative Psychology. The study tracked eight olive baboons, ages 4 to 14, in 54 separate trials of guess-which-cup-has-the-most-treats. Researchers placed one to eight peanuts into each of two cups, varying the numbers in each container. The baboons received all the peanuts in the cup they chose, whether it was the cup with the most goodies or not. The baboons guessed the larger quantity roughly 75 percent of the time on easy pairs when the relative difference between the quantities was large, for example two versus seven. But when the ratios were more difficult to discriminate, say six versus seven, their accuracy fell to 55 percent.

That pattern, argue the authors, helps to resolve a standing question about how animals understand quantity. Scientists have speculated that animals may use two different systems for evaluating numbers: one based on keeping track of discrete objects -- a skill known to be limited to about three items at a time -- and a second approach based on comparing the approximate differences between counts.

Spina bifida                                                   The same ( C )

Infant health conditions

Children suffering from various health conditions require a different level of energy intake from the consumption of food and this depends on the health danger the diseases posses to the body such as metabolic rate of the body.

Certain health conditions require high energy intake while certain health conditions require a lower energy intake such as ( Down syndrome and Prader-Willi syndrome ).

Hence we can conclude that the energy needs of each condition is as listed above.

Write half a page about why ATP is considered the energy-producing molecule and not GTP, CTP, or TTP

Answers

Answer:

Over the years, many proteins have specialized with a specific shape, and this chance is the primary reason behind ATP over GTP.

What is the genetic makeup?

A gene is a brief piece of DNA. Genes inform the frame a way to construct particular proteins. There are approximately 20,000 genes in every cell of the human frame. Together, they make up the blueprint for the human frame and the way it works. A person's genetic make-up is known as a genotype.
