The sand would feel warmer as the water has a higher heat capacity-the amount of heat energy required to increase temperature-. This allows large bodies of water such as oceans and lakes to absorb large amounts of heat with only small changes in temperature.
Anopheles is a genus of mosquito first described and named by J. W. Meigen in 1818. About 460 species are recognised; while over 100 can transmit human malaria, only 30–40 commonly transmit parasites of the genus Plasmodium, which cause malaria in humans in endemic areas.
