The dna sequence of a portion of a gene in a wild-type organism is ttaccatattcacco and the corresponding peptide sequence is leu pro tyr ser pro. the corresponding gene fragment in a phenotypic variant of the organism is ttaccatatctcaccc and the peptide sequence is leu-pro-tyr-leu-thr. this is an example of a(n) mutation (type) resulting in a mutation (effect)
a. insertion, missense

Which best describes red blood cells? a. they are colorless b. they protect against disease-carrying microorganisms c. they transport oxygen throughout the body d. they aid in blood clotting

Using the periodic table, determine which material is most likely a good conductor

Subduction zones form when an oceanic plate collides with another oceanic plate or continental plate. the continental crust is lighter and less dense than oceanic crust. continental crust's density is approximately 2.7 grams per cubic centimeter. oceanic crust is thinner and the average density is about 3.3 cubic centimeters. when the two crustal plates converge the oceanic plate always bends and subducts beneath a continental plate. once the oceanic crust subjects, the rocks are subjected to changes in heat and pressure. because of this, we would expect to find rocks in the area of a subduction. a) clastic b) igneous c) metamorphic d) sedimentary
