The wave's period is _____. - ANSWER 37 seconds The impact of waves is mostly observed, and most impacts mankind _____. - ANSWER along the coastline In deep water the movement of a water particle in a wave is _____. - ANSWER a circle Rip currents are found _____. - ANSWER perpendicular to shore Rogue waves...

Biogeography - ANSWER Study of variation in species composition and diversity across geographic locations regional species pool - ANSWER all the species contained within a region (gamma diversity) gamma diversity - ANSWER total species diversity in a landscape alpha diversity - ANSWER Species physiology and interactions with other species are important factors in the resulting species diversity beta diversity - ANSWER change in species, or turnover, from one community type to another...

Bactericidal - ANSWER kills bacteria antibiotic resistance - ANSWER Resistance evolving rapidly in many species of prokaryotes due to overuse of antibiotics, especially in agriculture. broad spectrum antibiotics - ANSWER affect a broad range of gram-positive or gram-negative bacteria Narrow spectrum antibiotics - ANSWER Effective against specific bacteria Sensitivity - ANSWER Ability to recognize and appreciate the personal characteristics of others subunit vaccines - ANSWER use a...

bactericidal - ANSWER kills microbes (bateria) directly Where are antibiotic resistance genes typically located? - ANSWER On plasmids or transposons that can be transferred between bacteria Examples of misuse that can lead to antibiotic resistance - ANSWER -using outdated or weakened antibiotics -using antibiotics for the common cold and other inappropriate conditions -using antibiotics in animal feed -failing to complete the prescribes regimen -using someone's leftover prescription ...

What is the path of light through the compound microscope? - ANSWER Light source --> condenser --> specimen --> objective lens --> ocular lens The image from the objective lens is magnified again by the ocular lens. What are the steps of a gram-stain? - ANSWER 1) Primary stain (crystal violet) - 1 minute 2) Mordant (Gram's iodine) - 1 minute 3) Decolorizing agent (ethanol) - 5 seconds 4) Counterstain (safranin) - 1 minute *blot dry, not wipe What is this specimen? -...
