Answer:
D. to protect the cell from harmful substances in the environment
Explanation:
Cell membrane is also known as plasma membrane is a biological membrane that differentiate the internal organelles of the cells from the outside environment. Cell membrane is made up of phospholipid bilayer with embedded proteins.
The main or primary function of cell membrane is to protect cell from harmful substances in the environment as it is the outer convering of the cell. cell membrane regulates movement of substances in and out of cells which restricts entry of harmful substances and hence called as selectively permeable membrane.
Hence, the correct option is D.

A. They live in the same area.
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

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.

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.
