the algae stimulate a virus that causes the tumors. Scientists have been trying to understand the pathology of these tumors. The tumors were most commonly located on the turtle’s heads‚ eyes‚ and flippers. According to Celia Smith‚ UH Mānoa Marine Biology Professor‚ “Many hypotheses were offered to explain the tumors‚ but we kept coming back to the observation that urban reefs—those near dense populations—are the sites with greater numbers of sick turtles. We had no mechanism for this disease” (Invasive

Biology laboratory work: Osmosis observation Measuring the dependence of net mass gain in potato pieces on concentration of sugar solution By Jonas Kulikauskas Siauliai Didzdvaris Gymnasium Hypothesis: The more sugar in solution‚ the more potato mass will decrease. Aim: To see how potato mass will change at different concentration solution. Research question: How the mass of potato will change at different concentration solutions? Variables: Dependent: solution concentration. Independent:

Kyle Eagle Human Biology BIO 108 G Final Exam Essays FINAL EXAM ESSAY 1). A cell is in the process of transcription. The single strand of DNA that is being copied has the sequence ATC GCA GGA TGC. Indicate the mRNA strand that will be synthesized from this strand‚ listing the correct sequence of bases. Describe why this step is important in the process of producing proteins. Explain how gene expression is regulated. The mRNA coding sequence can be described as units of three nucleotides

Biomolecules - Biology Unit 3 What is a Biomolecule? Organic molecule made by living organisms Organic Molecules: contain carbon considered the “chemicals of life” Inorganic Molecules: Do not contain carbon Consist mostly of: carbon (c)‚ hydrogen (h)‚ oxygen (o) Monomers vs. Polymers Monomers: single-molecule that may react with similar molecules to form a chain Polymers: a chain of many monomers that are chemically bonded together

AP Biology Summer Assignment Chapter 50.1: An Introduction to Ecology and the Biosphere Ecology is the scientific study of how organisms interact with the environment. When studying Ecology scientists want to know‚ where organisms live‚ why they live there‚ and how many are there. Ecology and environmental biology both stem from Darwin’s interest and observations upon the distribution of organisms and how they adapted to their specific environment. Darwin concluded that the environment interacting
