Answer:
The correct answer would be C. The tortoises provided evidence that different species have adaptations suited to their particular environments.
Darwin observed that how different environment on different island lead to the development of different species as a result of adaptations and natural selection.
For example, tortoise inhabiting well-watered islands which used to have short and cropped vegetation had developed a dome-shaped shell.
In contrast, the tortoise inhabiting the arid islands had developed saddle-shaped shells. It is because they needed to stretch their necks in order to reach branches of cactus and other vegetation available in the area.
Consequently, they developed long necks and high peak to the front edges of their shells. It made it possible for them to stretch their heads vertically.
Answer:
Modern method of irrigation is Sprinkling, Subirrigation,intrasoil and salt leaching are the principal purposes of surface irrigation
Answer:
microvilli, actin filaments
Explanation:
The apical ends of intestinal cells face the intestinal channel and have long processes that facilitate the absorption of nutrients. the name of these processes is microvilli and actin filaments from the cytoskeletal element forms their internal skeleton.
The hydrophilic molecules are the polar molecules which establishes the hydrogen bonding with the water molecules. Hence the hydrophilic molecules are water loving molecules. The hydrophobic molecules are unable to establish any hydrogen bonding with the water molecules. Hence the hydrophobic molecules are water repellent molecules.
