describe the major features of the clean water act (eg NPDES) and the safe drinking water act (eg MCL, MCLG) - Answer MCLG- maximum contaminant level goal- level at which there would be no adverse effect. Does not take into account cost of technical feasibility. MCL- maximum contaminant level - can be adverse effects, takes cost etc into account NPDES - national pollutant discharge elimination system, permitting system under CWA for nutrients and other toxins from point sources hydro...

Solar energy - Answer the primary power source that creates fossil fuels→ drives life on earth life cycle - Answer solar energy-->primary producers photosynthesize, herbivores consume primary producers--> carnivores, secondary carnivores→ detritivores consume decaying matter petroleum - Answer fossil fuel we use the most - 36%, oil sandwich - Answer layer of carbon/sand/silt/plankton biomass on top and bottom Canadian Tar Sands - Answer oily sand is scooped i...

Understand the major function of cells - Answer Cell differentiation: in bone marrow, adult stem cell can reproduce and splits to either myeloid or lymphoid progenitor, which can then differentiate into many kinds of cells Homeostasis and cell injury: many adverse biological effects occur when cells are damaged, damage can be to any part of the cell, causes can be infectious agents, oxygen deprivation, trauma, chemicals, nutritional imbalances Apoptosis vs. Necrosis - Answer Apoptosi...

Protein Synthesis - Answer DNA to mRNA via Transcription in the nucleus of the cell. RNA to protein via translation in the ribosomes. tRNA brings amino acids to the ribosomes in the correct sequence Mutagens - Answer pollutants in the environment that enter the body and directly change your DNA sequence Gene-gene interactions - Answer Pollutants that affect the functioning of one gene that directly affect the functioning of another gene Polymorphisms - Answer variation in D...

Two types of cell death - Answer apoptosis: programmed cell death necrosis: cell damage and death Virus vs bacteria - Answer virus: only active within host cells which they need to reproduce bacteria: single-celled organisms that produce own energy and can reproduce on their own DNA base pairing - Answer A-T G-C DNA strands held together by... - Answer hydrogen bonds DNA to protein - Answer DNA encodes the sequence of proteins carried in DNA Gene - Answer DNA ...

Genes influence physical development most directly by: A. Secreting certain enzymes that stimulate or inhibit growth B. Interacting with cells in the mother's placenta C. Controlling the speed with which electrical impulses flow D. Instructing the body to produce certain proteins - Answer D Human cells contain 23 pairs of chromosomes. Within each pair: A. Both chromosomes are inherited from the opposite-sex parent. B. One chromosome is inherited from the mother...

PUBH 6011 FINAL REAL EXAM QUESTIONS AND ANSWERS | PUBH6011 FINAL EXAM STUDY GUIDE LATEST UPDATES| A GRADE PASS!! Two differences between virus and bacteria - CORRECT ANSWER- 1. Bacteria are a single cell and can exist on their own (no nuclei or substructures) 2. Viruses must invade a host cell and use its genetic DNA Role of DNA in protein synthesis ?- CORRECT ANSWER- DNA acts as a template for RNA and encodes the sequence of proteins Role of mRNA in protein synthesis - CORRECT ANSWE...

PUBH 6011 Midterm Study Guide 2022. Week 1: How Energy Impacts Our Health • Explain how energy influences human health • The more energy usage a person has, generally the better they are living. Also generally extends our lives. • Energy protects form a lot of things...i.e. Refrigerator has temperature control protecting us from types of contamination that readily killed people a few 100 years ago. • Energy can also influence human health depending on the types of energy. Sustainab...
