Which of the following best explains how a scanning electron microscope is used to produce an image of a specimen? (4 points) a
An electron beam strikes the specimen, is absorbed by the specimen, and is used to produce an electrically charged image on a screen.

b
An electron beam passes over the specimen's surface and displaces electrons, which are then focused on a screen to form an image.

c
An electron beam traces an outline of the specimen onto a screen, and reflected electrons are collected to form the rest of the image.

d
An electron beam travels through the specimen, and as it does so it burns an image of the specimen on a screen.

All individuals have two alleles for a given trait. according to mendel's these alleles are passed down one each from both mother and father.

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
