They also have an open circulatory system and central nervous system. Like other terrestrial arthropods, they have trachea for breathing air and Malphigian tubules for excretion. Q: Where are more of an insect's internal organs kept? Choices: - the head - the thorax - the chest cavity - the abdomen A:
the abdomen

Q: Answer the following question given this paragraph: The transition elements have many properties in common with other metals. They are almost all hard, high-melting solids that conduct heat and electricity well. They readily form alloys and lose electrons to form stable cations. In addition, transition metals form a wide variety of stable coordination compounds, in which the central metal atom or ion acts as a Lewis acid and accepts one or more pairs of electrons. Many different molecules and ions can donate lone pairs to the metal center, serving as Lewis bases. In this chapter, we shall focus primarily on the chemical behavior of the elements of the first transition series. Q: Typically hard, high-melting solids that conduct heat and electricity well, the transition elements have many properties in common with other what? Choices: - oils - deposits - organics - metals A:
A: metals
Question: Answer the following question given this paragraph: Q: When are nutrients absorbed into the body? Choices: - after excretion - before digestion - after digestion - during digestion A:
Answer: during digestion
