Answer: Evidence for evolution comes from many different areas of biology: Anatomy. Species may share similar physical features because the feature was present in a common ancestor ( homologous structures ). Molecular biology. DNA and the genetic code reflect the shared ancestry of life.

Answer: A
. the history of the Hoover Dam and its impact on the Southwest region.
Explanation:
This question is based on the article, ''The Hoover Dam'' by Michael Stahl. In it the author begins by describing what hydroelectricity is and how it came about.
The author then used the Hoover Dam to illustrate the points made about hydroelectricity by first giving a brief history of the construction of the dam and the sacrifices it took to build it. The impact the dam had on the area it supplies - the Southwest - was also analysed.
Because of its rotation, the inner core of Earth is the cause of its magnetic field. This magnetic field helps protect the surface of the Earth from cosmic rays and other space-related particles. Human life could never have developed without this protection. The heat also accounts for most of the geological activity on Earth, including continent drift, and the magma associated with volcanic activity.
<span>Spirogyra, otherwise known as pond silk, is a type of algae that can be found in bodies of freshwater. The cells are long, unbranched, and cylindrical, being much longer than they are wide. There is no distinction between the basal and distal end, and they connect to each multiple times over to create the "silk" they are seen as; they also can reproduce sexually and asexually. Each cell has one nucleus and a cell wall composed of pectin surrounded by cellulose. Inside each cell is a very distinct spiraling shape of green, being chloroplast strands. It is these shapes for which the cells are named.</span>
The correct option is (D) the attraction between water molecules.
The attraction between water molecules cause surface tension.
<h3>What causes the water molecules' surface tension?</h3>
- Cohesive interactions between the liquid's molecule's cause the surface tension to develop. The molecules at the center of the liquid are surrounded by other molecules on both sides.
- The net force is zero because molecules are tugging on one another equally in all directions. In contrast to the majority of the liquid, the liquid molecules at the interface only have half as many nearby molecules.
- This results in a net inward pull toward the liquid and a stronger association of the molecule with the molecules on either side of it. The force preventing the surface from breaking is surface tension.
