The "internal environment" is: a) the blood cells b) body parts beneath the skin c) the cytoplasm of all the cells in the body d) plasma, interstitial fluid, and transcellular fluid e) intracellular fluid - correct answer plasma, interstitial fluid, and transcellular fluid Which of the following is an example of positive feedback? a) Consuming caffeine increases urine output, causing dehydration b) The ...

SFSU Biology 230 Exam Questions with Answers What are the relationships among genomes, chromosomes, genes, alleles, proteins, traits, and mutations? - Answer-Genomes are chromosomes that are in gametes. Alleles are different versions of the same gene. Proteins directly impact traits. A mutation is an allele and something could be different about the protein. What are the similarities and differences in what DNA, RNA, and proteins are made of? - Answer-DNA, RNA, and proteins are made of mac...

U-ABC-IT - correct answer Use evidence, ask questions, be skeptical, cultivate wonder, identify confusions, think like a biologist What are the common functions of living things? - correct answer Move, reproduce, exchange gasses, grow What are common structures of living things? - correct answer Tissues, organelles, organs, cells Which of the following are considered to be alive?

What are the similarities and differences in what DNA, RNA, and proteins are made of? - correct answer DNA, RNA, and proteins are made of macromolecules. DNA and RNA is ...

What are the three core concepts of biology that we have used to frame our studies together so far? - correct answer structure and function, information flow, transformation of energy into matter How would you explain to a fellow student what "Transformations of Energy and Matter" is about? - correct answer energy can not be created nor destroyed but rather converted Why do you think it is important enough to be considered a core concept? - correct answer How would you explain ...

DNA - correct answer Are made up of 46 chromosomes that have alleles within them that with those alleles Prion - correct answer Are misfolded proteins that cause other similar proteins to misfold Not made of cells. Not have DNA RNA. Are not viruses Are causative of Mad cow disease Non-Coding DNA - correct answer Promoters and introns(parts of process) 98% of genome is noncoding - DNA that doesn't get coded into a protein RNA - correct answer Ribonucleic acid; a type of nucle...

How are chromosomes, genes, alleles, proteins, traits and mutations related? - correct answer Chromosomes contain DNA which contains genes that can vary and are then called alleles, which code for proteins that can be expressed as traits. Mutations happen. What causes cancer?Are all mutations caused by mutagens? - correct answer Cancer can be caused by inheritance or sporadic mutations (mutagens). Not all mutations are caused by mutagens. ** How do you go about determining whether the ...

Why is homeostasis important? - correct answer to maintain a relatively stable environment, within limits. How does the body maintain homeostasis? - correct answer through cooperation of multiple organ systems, including the endocrine and nervous system What is a homeostatic set point? - correct answer The level in where the temperature of the body is maintained. Which organs are involved in water, and glucose balance? - correct answer The small intestine is involved with balanc...
