Answer the following question given this paragraph: The cells of the blastocyst form an inner cell mass and an outer cell layer, as shown in Figure below . The inner cell mass is called the embryoblast. These cells will soon develop into an embryo. The outer cell layer is called the trophoblast. These cells will develop into other structures needed to support and nourish the embryo. Q: The cells of the blastocyst form an inner cell mass called the what? Choices: - blastocyst - chloroplast - xerophyte - embryoblast A:
embryoblast

Q: Answer the following question given this paragraph: For many decades, scientists have known that atoms consist of electrons and other particles called protons and neutrons. Recently they found that there are even smaller particles in atoms. Scientists call these extremely tiny particles by the funny name of quarks. As you can see in this diagram, there are several different kinds of quarks, called up quarks, down quarks, top quarks, bottom quarks, charm quarks, and strange quarks. In this chapter you'll learn about these unusual particles and also other particles inside the atom. Q: For many decades, scientists have known that atoms consist of electrons and other particles called protons and? Choices: - rods - waves - nanoparticles - neutrons A:
A: neutrons
