Answer:
Homologous structures provide evidence for common ancestry analogous structures show that similar selective pressures can produce similar adaptations beneficial features Similarities and differences among biological molecules in the DNA sequence of genes can be used to determine species relatedness
The deeper you go down in to the rock the older the fossils get. So when the scientists go in to the rock they can say what animals lived in that time and what animal was the oldest.
Answer: adaptability
Explanation:
Adaptation is a change that occur in the genetic make up, morphology and physiology of the living organism so as to make it suitable for survival in the adverse conditions.
Camouflage is the ability of the organism to change it's physical features or morphology so as to remain protected against the danger of being harmed by the predators or to take advantage of being hidden from the eyes of prey so as to obtain it as food. Camouflage is a kind of adaptation which makes the organism capable of surviving in the adverse environmental conditions.
Flounder is a species of flat fish. These fishes can be found near the sea bed. They posses an adaptation of camouflaging the predators by their skin. The color of these fishes blends with their surrounding lower bottom sediments. This makes them undetected by the predators such as shrimps, fish larvae and worms.
Plant cell growth, an irreversible increase in cell volume, can occur by expansion (increase in cell size in two or three dimensions) or by elongation (expansion constrained to one dimension). Variety in cell shape may result if either of these two processes occur only at specific regions of the cell surface.
