Answer:
Scientific theory definition, a coherent group of propositions formulated to explain a group of facts or phenomena in the natural world and repeatedly confirmed through experiment or observation: the scientific theory of evolution.
Explanation:
It makes sense that cell membranes are made of phospholipids because water cant mix in with lipids, so the phospholipids will be able to effectively block out any unwanted water or chemicals suspended in water outside of the cell.
The correct answer is D) Where water covers the land
Explanation:
Broken up land land contributes to a loss of species diversity through geographoc isolation. Geographic isolation is the physical barrier dividing the communities. It usually stops the gene flow between species in a process called allopatric speciation, contributing to reproductive isolation.
Further Explanation:
Spontaneous modifications in the genome can occur during the cycle of cell division, called mutations. These errors occur as copies of the DNA are produced within the cell; mutations may range from small modifications called single nucleotide polymorphisms to large-scale deletions and multi-gene additions.
Such mutations create variations that within a group become dominant, resulting in the creation of different, genetically distinct organisms called species.

The essential components of the human cardiovascular system are the heart, blood and blood vessels. It includes the pulmonary circulation, a "loop" through the lungs where blood is oxygenated; and the systemic circulation, a "loop" through the rest of the body to provide oxygenated blood.
Hope this helps!
