Read the following scenario to answer the following question(s).Malaria is a disease caused by parasitic protists in the genus Plasmodium. The parasite is transmitted to humans by female Anopheles mosquitoes. The Plasmodium parasite feeds on human red blood cells, eventually destroying them. Humans infected with malaria can exhibit many symptoms. Depending on the severity of the infection, these can range from fever, chills, sweating, and headaches to anemia and kidney failure. Ultimately, malaria can result in death. However, if time and money permit, once a person is infected, they can be treated with different antimalarial drugs. Two commonly used drugs are artemisinin and quinine. In addition, one way to prevent the spread of malaria is to apply pesticides to treat areas with Anopheles mosquitoes. The National Malaria Eradication Program began work in 1947 with the goal of eliminating malaria from the southern United States. In 1947, 15,000 cases of malaria were reported nationwide. By 1950, only 2,000 cases were reported, and by 1951, malaria was considered eradicated from the United States. Today, the disease is most common in Africa and South America, two continents that are highly impoverished. About one million people die from malaria every year, many of them children. In Africa, it is estimated that one in every five childhood deaths is due to malaria.A vector is an organism that transfers a pathogen to a host. In the case of malaria, the vector(s) is (are) ________.

Imagine that we are ancients and we know that the earth is spherical because we have observed its shadow on the moon. In addition, we know that the earth rotates about its own axis because of the fact that we see day and night and the stars moving in circles around Polaris. After walking a distance of 50 km toward the north pole, we notice that the pole star is 1 degree higher in the sky. What is the circumference of our earth?

Today’s model of our solar system is
