Simple Sequence DNAs are known to be located in which areas of the chromosome - found in centromere and some in telomere; interacts with the kinetochore Simple Sequence DNA - constitutes about 6% of the human genome, also called satellite DNA, concentrated near the centromere, backward slippage is used, number of repeats are vastly different, simple sequence is mobile; doesn't code for anything Gene - a unit of heredity that is transferred from a parent to offspring and is held to determin...

Rank-abundance curves - Plot the relative abundance of each species in a community in rank order from most abundant to least abundant Species Accumulation Curve - Graph of the number of species observed in relation to the number of individuals sampled True or false; another way to estimate the number of species in an area is based on the number of rare species detected. - True Biodiversity is built from what 3 features? - Ecosystem diversity, species diversity, genetic diversity Species t...

During primary exposure to a pathogenic microbe, what is the role of innate immune cells? - trigger the inflammatory response to recruit immune cells eliminate microbes by phagocytosis and antimicrobial proteins limit growth and spread of microbes with antimicrobial proteins activate adaptive immunity with antigen presentation and cytokine Activation of a mature naive T cell by an APC requires three critical signals. Which of the following is NOT an intracellular signal generated in the T ...

Convection - *Transfer of heat by movement of liquids and gases (Molecules of air or water next to warm surface gain energy and move away from surface)*When environment is cold, organism warms it's boundary layer which reduces heat loss but current of air can disrupt layer and carry away heat by convection (wind chill) Radiation - *Emission of electromagnetic energy by surface (i.e. sun) *When objects are warmed by radiation, they emit lower-energy radiation as infrared light *The temp of...

True False - True In Type I hypersensitivities IgG bind to mast cells after the second exposure IgG bind to T cells after the second exposure IgG bind to mast cells after the first exposure IgG bind to T cells after the first exposure IgE bind to mast cells after the second exposure IgE bind to T cells after the second exposure IgE bind to mast cells after the first exposure IgE bind to T cells after the first exposure - IgE...

Dental Hygiene National Board question and answer 2022/2023What are some examples of bio-hazard waste? Sharps, items that drip of blood and/or saliva, and hard and soft tissues removed from patient The bio-hazard waste or regulated true or false? True When should we change our mask? When it becomes wet or soiled with every patient. That includes your fluids as well. What is the purpose of PPE? Is to minimize the exposure to Aerosol, Spatter, Direct transmission, ...
