Answer:
The main trait that was different between sharks 14 and 9 was that shark 14 (Mobulidae) has a front with two points that look like horns, whereas shark 9 (Dasyatidae) has a front with no points that look like horns.
Explanation:
The traits that Aristotle would have used to classify sharks are :
Front with points ( hornlike )Front without points Sharks classificationSharks whose front have two points like horns are classifed by Aristotle as sharks 14 (Mobulidae). whlie sharks whose front does not have two points like horns are classifiesd as sharks 9 ( Dasyatidae ). hence the traits that would have been used by Aristotle to classify sharks is the presence of points at the front.
Hence we can conclude that the traits that Aristotle would have used to classify Sharks are Front with points and front without points.

B. They have the same density
D
C. They are the same species.
D. They live at the same time.
E. They are the same size
Answer:
the answers are a, c, and d
Explanation:
a makes sense because if you are a member of a population then the other members live in the same area as you
b doesn't make sense because even though you live in the same population as someone, it doesn't mean you'd have the same density
c makes sense because the definition of population is, "a group of individuals of the same species living and interbreeding within a given area."
d makes sense since in order to be considered a member of a population you have to be living
e doesn't make sense since everyone is a different size

During their early stages of development, the embryos of reptiles, birds, and mammals look very similar. The embryos of reptiles, birds, and mammals also have many of the same structures and develop in similar patterns. This suggests that reptiles, birds, and mammals... *
Answer:
share a common ancestor
Explanation:
The similarity in their embryos and embryonic development suggests that reptiles, birds, and mammals share the same ancestor.
Similarity in the structure and development of embryo is one of the evidences that is been used by scientists to support the theory of evolution of species. According to the theory of organic evolution, all organisms are on earth as a result of descent with modifications from common ancestors.
Reptiles, birds, and mammals are all vertebrates. They share some basic characteristics and are thought to have shared a common ancestor before each group took different adaptive channels leading to their differences as they currently exist.

Write a summary of the pathways rocks can take to become sedimentary, igneous, and metamorphic rocks.
Answer:
When a certain type of rock, specifically, an igneous rock, is deeper into the ground, and it is under the influence of high temperatures and pressures, it will start to change its molecular structure over time. In addition to the high temperature and pressure, chemical influences are also very important, so the the rock will gradually turn into a metamorphic rock.
Depending on the type of influences, and their intensity as well, one type of rock can evolve into multiple different types of metamorphic rocks.

What feature is the same in the formation of many sedimentary rocks and fossil fuel?many sedimentary rocks and fossil fuels-
A-require material to be buried and exposed to heat amd pressure.
B-are made out of organic material that stores the sun energy
C-form where there are frequent earthquakes and volcanic activity
D- are produced high in the mountains where temperatures are low
Answer:
maybe C i'm so sorry if this is wrong
Explanation:
Organic materials and silt build on top to produce fossil fuels. Heat and pressure transform organic materials into coal, petroleum, or natural gas. Therefore, option (A) is correct.
What are fossil fuels?An extracted and burnt fossil fuel is a hydrocarbon-containing substance that naturally originated in the Earth's crust from the remnants of extinct plants and animals. Coal, oil, and natural gas are the three primary fossil fuels.
Because certain sedimentary rocks contain trapped fossil fuels, sedimentary rocks and fossil fuels are connected. As organic materials and silt build up on top over time, fossil fuels are created. The organic material undergoes a chemical shift under heat and pressure, turning it into coal, oil, or natural gas.

When he finishes his model, Jeremy notices that the shapes and sizes of the continents are not correct. He also notices that the Earth's surface is cut off at the edges of the drawing. Jeremy decides that he wants his model to be more accurate. How can Jeremy improve his model so that it is more accurate? A. Use a ruler to draw the continents with straight lines. B. Use a thicker piece of paper. C. Draw the Earth on a sphere. D. Draw the Earth smaller on the paper.
Answer: C. Draw the Earth on a sphere.
Explanation:
Jeremy should draw the Earth like a small sphere that can be drawn completely on the paper and edges will not be left incomplete. The shape and size of the continent can be traced using a map or a stencil. The exact dimension to be drawn is not important but the boundaries should be taken care of and must be accurate.
