Answer:
"Survival of the fittest" is a phrase that originated from Darwinian evolutionary theory as a way of describing the mechanism of natural selection. The biological concept of fitness is defined as reproductive success. Darwinism is a theory of biological evolution developed by the English naturalist Charles Darwin (1809–1882) and others, stating that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce. Also called Darwinian theory, it originally included the broad concepts of transmutation of species or of evolution which gained general scientific acceptance after Darwin published On the Origin of Species in 1859, including concepts which predated Darwin's theories. English biologist Thomas Henry Huxley coined the term Darwinism in April 1860.
Bacteria living in a deep ocean vent I think
No, since it is an island separate from the mainland Ecuador and has been uniquely isolated over the past several hundred thousand years, the species on the Galapagos Islands have had time to evolve differently and separately than those in Ecuador, leading to many different, diverse species on the Galapagos that don't exist in Ecuador
I’m sorry i didn’t really understand what your asking, or is there options to choose from?
Answer:
One-half b c sine (60 degrees)
One-half a squared sine (60 degrees)
StartFraction a b sine (60 degrees) Over 2 EndFraction
Explanation:
The area rule states that the area of any triangle is equal to half the product of the lengths of the two sides of the triangle multiplied by the sine of the angle included by the two sides.
From the question, Equilateral triangle refer to a triangle with equal angle and equal sides. The sum of an angle in a triangle = 180°; this implies that each angles have 60°.
∴ the three options that defines the expressions that represent the are of triangle ABC are:
One-half b c sine (60 degrees)
i.e 
One-half a squared sine (60 degrees) ; if the two opposite sides posses the same parameters.
i.e 
StartFraction a b sine (60 degrees) Over 2 EndFraction
