Fossils provide<span> solid </span>evidence<span> that organisms from the past are not the same as those found today; they show a progression of </span>evolution<span>. Scientists calculate the age of </span>fossils<span> and categorize them to determine when the organisms lived relative to each other.</span>
During a new or full moon
Explanation:
This is because, during these lunar phases, there is a spring tide – during high tides. Therefore because the ocean water-levels are high, storm surges push more water towards the coast leading to more destruction. Remember a storm surge is the pushing of water towards the coastline by strong cyclonic winds. A combination of astronomical tide and a storm surge is called a storm tide and is the most destructive.

C. The vestigial structures. <span>A </span>vestigial structure<span> is an anatomical feature that no longer seems to have a purpose in the current form of an organism of the given species. Often, these vestigial structures were organs that performed some important function in the organism at one point in the past. However, as the population changed due to</span>natural selection<span>, those structures became less and less necessary until they were rendered pretty much useless. While most of these types of structures would probably disappear over many generations, some seem to keep being passed down to offspring even though they have no known function.</span>
1. Knowing our family’s medical history can be useful for us and our doctors because it can help to check the possibility of occurrence of genetic disorders. Genetic disorders are passed on through several generations. Diseases like hemophilia and color blindness are some examples.
2. Contaminated water can negatively affect the health of an individual as well as a community. Pathogens contained in contaminated water causes several diseases. Diseases like cholera and typhoid are examples of water-borne diseases.
The bacterium that causes typhoid is Salmonella typhi and the pathogen that causes cholera is the bacterium Vibrio cholera. The consumption of water contaminated by the feces of a person infected with cholera cause the spreading of disease to a healthy person. Contaminated water and poor sanitation is the cause of typhoid spread as well.
3. Two types of drugs are stimulants and hallucinogens. Stimulants increase the alertness of the person who uses it and increases the heart rate, blood pumping rate and blood glucose levels. Cocaine is an example of stimulant drug.
Stimulant abuse can lead to anxiety, paranoia, depression etc. hallucinogens disconnect the link to the brain and users experience unstable and rapid emotions and have hallucinating visions.LSD is an example of hallucinogen. Hallucinogen abuse can cause cognition distortions, paranoia, anxiety etc.
