Answer the following question given this paragraph: The first period of the Paleozoic Era was the Cambrian. By the beginning of the Paleozoic, organisms evolved shells. Shells could hold their soft tissues together. Shells could protect them from predators and from drying out. Some organisms evolved external skeletons. These are called exoskeletons . Organisms with hard parts also make good fossils. Fossils from the Cambrian are much more abundant than fossils from the Precambrian. Q: The first period of the paleozoic era was called what? Choices: - carboniferous - permian - ordovician - cambrian A:
cambrian
Q: Answer the following question given this paragraph: Equal volumes of four different gases at the same temperature and pressure contain the same number of gaseous particles. Because the molar mass of each gas is different, the mass of each gas sample is different even though all contain 1 mol of gas. The relationships among the volume of a gas and its pressure, temperature, and amount are summarized in Figure 10.10 "The Empirically Determined Relationships among Pressure, Volume, Temperature, and Amount of a Gas". Volume increases with increasing temperature or amount but decreases with increasing pressure. Q: What does increased temperature cause the volume to do in a gas? Choices: - disappear - decrease - halve - increase A:
A: increase
Question: Answer the following question given this paragraph: Human cells have 23 pairs of chromosomes, and each chromosome within a pair is called a homologous chromosome . For each of the 23 chromosome pairs, you received one chromosome from your father and one chromosome from your mother. Alleles are alternate forms of genes found on chromosomes. Homologous chromosomes have the same genes, though they may have different alleles. So, though homologous chromosomes are very similar, they are not identical. The homologous chromosomes are separated when gametes are formed. Therefore, gametes have only 23 chromosomes, not 23 pairs. Q: How many pairs of chromosomes are found in human cells? Choices: - 25 - 24 - 13 - 23 A:
Answer: 23
