It depends on how many points out of how many points you had to get the 87.29%
But I think your grade is a B....
89.95% and up = A
79.95% to 89.94% = B
69.95% to 79.94% = C
so yeah

Answer;
A skull from genus Homo that dates from approximately 750,000 years ago is discovered. Then the foraman magnum is most likely be located at the bottom of the skull.
Explanation;
Foramen magnum is a large opening at the base of the skull through which the spinal cord exits the cranial vault. It is situated in the occipital bone, and forms around the base of the brainstem, separating the brain from the spinal cord. In apes and humans (members of genus homo) it is formed by the fusion of the four parts of the occipital. In human for example; it is anteriorly positioned, with its interior lying on the bitympanic line and is also inferiorly oriented.
The remains of the living organisms used in understanding the history of life on Earth is fossils.
Fossils are the preserved remains of plants and animals whose bodies are buried in sediments such as sand and mud under ancient seas, lakes and rivers.
Fossils are the geologically altered remains of once-living organisms and/or their behavior. There are mainly two types of her: Body fossils represent all or part of an organism's body, while vestigial fossils show an organism's behavior.
Fossils form in a variety of ways, but most often form when living organisms (such as plants or animals) die and are quickly buried by sediment (such as mud, sand, or volcanic ash).
Fossils are found mainly in river valleys, cliffs and hills where sedimentary rocks of appropriate age are exposed, and in areas of human exposure such as quarries and road cuttings.

1. Animals have some amazing adaptations that help them live in even the most hostile environments. Consider camels, for instance. They can thrive in some of the hottest and driest places on Earth. Their legs don’t get burned when they kneel on hot sand due to thick leathery patches on their knees. They can survive for an entire week without water but, at the same time, they can drink 32 gallons of water at once. Their body temperature ranges from 93 °F to 107 °F, so they don’t need to sweat very often and can conserve water this way. The spongy bones in their noses absorb any excess moisture to keep every drop of water in, so the air they breathe out is dry air. In addition to camels, other animals’ adaptations are equally remarkable.
2.When you sweat, breathe heavily and feel your heart pounding, it doesn’t just mean you are having a good workout. These physiological factors are also vital to your body maintaining a state of homeostasis. Homeostasis is defined as a constant, steady environment despite external changes, such as exercise. Exercise affects your body temperature, blood oxygen levels, sugar levels and hydration – all properties necessary for your survival. Your body uses an automatic feedback system to preserve normal temperature and water levels, so you can keep exercising.
hope it helps
