The three scientific principles of sustainability are: (1) dependence on solar energy, (2) Biodiversity, and (3) chemical cycling.
dependence on solar energy - the energy imparted to the earth system by the sun. The sun warms the planet and provides energy that plants use to produce nutrients. The sun also powers indirect forms of solar energy such as wind and flowing water.
biodiversity -
Scientists have found that extracellular matrix component may induce specific gene expression in the embryonic tissues such as the liver and testes. For this to happen, there must be a direct communication between the extracellular matrix and the developing cells. The Integrins of transmembrane protein would most likely be involved in this kind of induction.
Integrins are the main principal receptors used by the cells of animal to bind to the matrix of extracellular. They are heterodimers and they function as transmembrane linkers between the actin cytoskeleton and the extracellular matrix. A cell can regulate the sticky activity of its integrins from within.

Answer:
A.
Explanation:
Sexual reproduction requires that diploid organisms produce haploid cells that can fuse during fertilization to form diploid offspring.
Answer:
One.
Explanation:
The attached figure shows the diagram of the given question.
We need to find how many angles are alternate exterior angles with angle 5?
Exterior angle = Angle that is made outside of the shape
Alternate angle = an angle opposite of a transversal line of another angle.
From the figure, 8, 7, 9, 10, 12, and 11 are the angles that are on the same transversal. 8, 7, 9, 10, and 12 are just exterior. It means that 11 is the alternate exterior of angle 5. So, only one angle is alternate exterior angles with angle 5.
