Answer:
the answer is wave action
Explanation:
When you work in a School Lunch program, you’re bound to face challenges that pop up seemingly out of nowhere. That’s just the nature of serving hundreds or even thousands of students each day.
But, when you keep encountering the same Child Nutrition program problems, over and over, day after day, it’s likely more than just a coincidence.
Instead, there probably are bigger issues causing these problems.
The bad news is that it often can be unclear what these bigger issues are, which makes fixing them almost impossible.
The good news? We at Harris School Nutrition Solutions have spent thirty years working with the men and women of Child Nutrition programs all across the U.S., helping to diagnose and solve their School Lunch problems.
So, we figured we’d share with you some of the common school lunch-line challenges we’ve seen over the years, the real issues behind those challenges, and of course the solutions to both.
The answer is D. I looked up a conversion calculator and that's what it told me.
Answer:
The purpose of the crest was to provide a surface for masticatory muscle attachment or insertion.
Explanation:
This crest is called the sagittal crest. It is present in extinct hominids, such as Australopithecus and Paranthropus, and can also be found in living animals such as gorillas or lions and some reptiles.
The sagittal crest is a bony structure that crosses the hominids´ skull longitudinally, and it is so well-developed that it stands out notoriously.
This crest, like others in the skulls, provides an attachment surface for many muscles. In the particular case of the sagittal crest, it is believed to provide an insertion area to mastication muscles.
It seems that Australopithecus had a special diet composed of tough items. The hominid probably needed to strong bite while eating. The strong jow muscles gave them the possibility to bite but needed a wide area for insertion. The sagittal crest provided that wide surface. There was a direct relationship between the size of the crest and the muscle mass. The bigger the crest was, the more developed the muscle was.
It is believed that in living animals, such as gorillas, the development of the crest in males is for sexual selection and reproductive success. The bigger the crest is, the more attractive the male is, and the more chances to be selected by the female to mate it will have. Some hypothesize that the development of the crest in Australopithecus could also be related to sexual selection.
