The cardiac notch is the concave area in the left lung that leaves a space for the heart to accomodate. The corrcet answer is cardiac notch.
What is the cardiac notch?
The left lung has superior and inferior lobules, one oblique fissure, it is adjacent to the heart, the aortic arch, the thoracic aorta, and the esophagus. It also has a cardiac notch.
The cardiac notch is a concave lung area where the heart accommodates. Its main function is to leave a space for the heart to lay. It is placed in the anteroinferior border of the superior lobule of the lung.
Since the cardiac notch is the area where the heart is placed, it only appears in the left lung.
The correct answer is cardiac notch. The medial surface of the left lung has a cavity that accommodates the contents of the mediastinum. It is called the _ cardiac notch_.

varieties of which type of atoms?
Carbon isotopes
Sodium isotopes
Phosphorous isotopes
Oxygen isotopes
Answer: Oxygen Isotopes!
Explanation:
I just took the quiz and I got it correct!
Carbon and oxygen Isotopes are the two atoms present in shells of single-celled plankton that sank to the bottom of the ocean.
Composition of shellThe shells of single celled plankton is made up of calcium carbonate or from tiny grains of sand stuck together. Mostly, they are made of calcium carbonate and we know that carbonate is formed from one carbon atom and three oxygen atom.
So we can conclude that carbon and oxygen Isotopes are the two atoms present in shells of single-celled plankton that sank to the bottom of the ocean.

AaGG x aaGg
Which genotype is NOT possible in the offspring produced by the cross?
The genotype Aagg is not possible in the offspring. It is due to gamete combinations.
What are gamete combinations?Gamete combination refers to the presence of particular alleles in the gametes of a genetic cross.
Gamete combination largely determines the possible genotypes and phenotypes observed in offspring.
In this case, one parent does not have the allele referred as 'g' and therefore the offspring cannot be homo-zygous for this allele.

Que características poseen los babuinos que no poseen los Lemures
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.

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.
