Answer the following question given this paragraph: Watch this video (http://openstaxcollege. org/l/symmetry2) to see a quick sketch of the different types of body symmetry. Layers of Tissues Most animal species undergo a layering of early tissues during embryonic development. These layers are called germ layers. Each layer develops into a specific set of tissues and organs. Animals develop either two or three embryonic germs layers (Figure 15.5). The animals that display radial symmetry develop two germ layers, an inner layer (endoderm) and an outer layer (ectoderm). These animals are called diploblasts. Animals with bilateral symmetry develop three germ layers: an inner layer (endoderm), an outer layer (ectoderm), and a middle layer (mesoderm). Animals with three germ layers are called triploblasts. Q: What term is used to describe animals with three germ layers? Choices: - sporozoans - triplegerm - multilayer - triploblasts A:
(Answer)
triploblasts
Ques: Answer the following question given this paragraph: An alternative way to define the concentration of a solution is molality, abbreviated m. Molality is defined as the number of moles of solute in 1 kg of solvent. How is this different from molarity? Would you expect a 1 M solution of sucrose to be more or less concentrated than a 1 m solution of sucrose? Explain your answer. What are the advantages of using solutions for quantitative calculations?. Q: The number of moles of solute in 1 kg of solvent is defined as what? Choices: - singularity - pollenation - kilocalorie - molarity A:
Ans: molarity

Answer the following question given this paragraph: Suppose that you wanted to know how many hydrogen atoms were in a mole of water molecules. First, you would need to know the chemical formula for water, which is H 2 O. There are two atoms of hydrogen in each molecule of water. How many atoms of hydrogen would there be in two water molecules? There would be 2 2 = 4 hydrogen atoms. How about in a dozen? In that case a dozen is 12 so 12 2 = 24 hydrogen atoms in a dozen water molecules. To get the answers, (4 and 24) you had to multiply the given number of molecules by two atoms of hydrogen per molecule. So to find the number of hydrogen atoms in a mole of water molecules, the problem could be solved using conversion factors. Q: H2o is the chemical formula for what? Choices: - glass - smog - salt - water A:
(A).
water
Ques:Answer the following question given this paragraph: There are two basic types of electric circuits, called series and parallel circuits. They differ in the number of loops through which current can flow. You can see an example of each type of circuit in Figure below . Q: Series and parallel circuits are two basic types of what? Choices: - mechanical circuits - chemical circuits - mutual circuits - electric circuits A:

Ans:electric circuits
Question: Answer the following question given this paragraph: Like the immune systems of other vertebrates, the human immune system is adaptive. If pathogens manage to get through the body's first two lines of defense, the third line of defense takes over. The third line of defense is referred to as the immune response . This defense is specific to a particular pathogen, and it allows the immune system to "remember" the pathogen after the infection is over. If the pathogen tries to invade the body again, the immune response against that pathogen will be much faster and stronger. Q: The third line of defense of the immune system is called? Choices: - the sudden response - the asymptomatic response - the malignant response - the immune response A:
Answer:
the immune response
