Absorbance - Study guides, Class notes & Summaries

TAMU bio 111 lab exam 2 review (2023/2024) already passed What is the difference between the coding and non-coding region? Coding region: comprised of genes that encode proteins (instructions that determine traits) and makes up 1-2% of human DNA. • Noncoding region: makes up 98-99% of human DNA, contains STRs and is responsible for regulatory functions such as gene transcription. What are STRs? Short-tandem repeats (STRs) are unique repeating patterns of the same nucleotide sequence. They can...

NU 578 Unit 4 Test With Latest 100%Correct Answers. Insulin use - ANSWER Insulin is used to treat all patients with type 1 and many with type 2 diabetes. consists of two amino acid chains (a acidic and b basic) linked by two disulfide bridges. it is synthesized in the pancreas by b ce;;s within islets of langerhans. insulin is released by rise in blood sugar (eating a. meal). Anaolic reaction (insulin promotes conservation of energy and buildup of energy stores) Insulin metabolic actions...

Which formula correctly describes the relationship between absorbance and %T ? A. A = 2 - log %T B. A = log 1/T C. A = -log T D. All of these options Answer D Absorbance is proportional to the inverse log of transmittance. A = -log T = log 1/T Multiplying the numerator and denominator by 100 gives: A = log (100/100 X T) 100 X T = %T, substituting %T for 100 X T gives: A = log 100/%T A = log 100 - log %T A = 2.0 - log %T For example, if %T = 10.0, then: A = 2.0 - log 10.0 log 10...

Portage Learning microbiology module 3 Exam 2024 A nanometer is defined as: -Answer-10-9 A nanometer is defined as one-billionth of a meter True or False: A nanometeris longer than a micrometer -Answer-False. A nanometer is 1,000 times smaller than a micrometer. Resolution and contrast are two critical factors that influence your ability to see an object. Explain each. -Answer-Resolution refers to the distance between two objects at which the objects still can be seen as separate. Poor o...

Beer's law says... Correct Answer-Absorbance is proportional to concentration Beer's law formula and purpose Correct Answer-A = ϵlc A: absorbance (measured by the spectrophotometer) ϵ: extinction coefficient l: path length of light through sample (usually 1 cm - printed on the cuvette) c: concentration To calculate concentration Absorbance formula Correct Answer-A = -log(I/Io) I: intensity of incident light Io: intensity of transmitted light To measure absorbance Beer...
