Doctors have found a dna marker that predicts the inheritance of a deadly disease, als. the band of markers labelled "c"
shows the pattern inherited by people with the disease. one member of the green family, the father, has als. his four children
have been tested and the results are shown here. to inherit the disease, you must inherit all markers. will any of mr. green's
children have the disease? explain.

helicase, i think thats it

organ system-an organ system is a group of organs that work together to perform one or more functions. each does a particular job in the body, and is made up of certain tissues.

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
