Answer the following question given this paragraph: An air mass takes on the conditions of the area where it forms. For example, a continental polar air mass has cold dry air. A maritime polar air mass has cold moist air. Which air masses have warm moist air? Where do they form?. Q: What kind of air does a continental polar air mass hold? Choices: - cool moist air - frigid wet air - warm dry air - cold dry air A:
cold dry air
Answer the following question given this paragraph: A unit cell is the smallest portion of a crystal lattice that shows the three-dimensional pattern of the entire crystal. A crystal can be thought of as the same unit cell repeated over and over in three dimensions. The Figure below illustrates the relationship of a unit cell to the entire crystal lattice. Q: What is the smallest portion of a crystal lattice? Choices: - ionic cell - function cell - element cell - unit cell A:
unit cell
Q: Answer the following question given this paragraph: A population can't keep growing bigger and bigger forever. Sooner or later, it will run out of things it needs. For a given species, there is a maximum population that can be supported by the environment. This maximum is called the carrying capacity . When a population gets close to the carrying capacity, it usually grows more slowly ( Figure below ). When the population reaches the carrying capacity, it stops growing. Q: For any given species, what term means the maximum population that can be supported by the environment? Choices: - zero population growth - mass extinction - tipping point - carrying capacity A:
A: carrying capacity
Question: Answer the following question given this paragraph: From Genotype to Phenotype Each human body cell has a full complement of DNA stored in 23 pairs of chromosomes. Figure 28.24 shows the pairs in a systematic arrangement called a karyotype. Among these is one pair of chromosomes, called the sex chromosomes, that determines the sex of the individual (XX in females, XY in males). The remaining 22 chromosome pairs are called autosomal chromosomes. Each of these chromosomes carries hundreds or even thousands of genes, each of which codes for the assembly of a particular proteinthat is, genes are "expressed" as proteins. An individual's complete genetic makeup is referred to as his or her genotype. The characteristics that the genes express, whether they are physical, behavioral, or biochemical, are a person's phenotype. You inherit one chromosome in each paira full complement of 23from each parent. This occurs when the sperm and oocyte combine at the moment of your conception. Homologous chromosomesthose that make up a complementary pairhave genes for the same characteristics in the same location on the chromosome. Because one copy of a gene, an allele, is inherited from each parent, the alleles in these complementary pairs may vary. Take for example an allele that encodes for dimples. A child may inherit the allele encoding for dimples on the chromosome from the father and the allele that encodes for smooth skin (no dimples) on the chromosome from the mother. Q: A complementary pair of chromosomes have genes for the same characteristics in the same location on the chromosome are known as? Choices: - analogous chromosomes - endroctyne chromosomes - symbiotic chromosomes - homologous chromosomes A:
Answer: homologous chromosomes

Answer the following question given this paragraph: There are a number of different ways to measure the strength of a given crystal lattice. One way would be to measure the amount of energy needed to completely pull apart an ionic substance into isolated ions. This value, known as the lattice energy , cannot be measured directly, but it can be calculated based on measured energy changes for other more feasible processes. The lattice energy of an ionic solid provides us with one way to measure the relative strength of the ionic bonds in that compound. Table below shows the lattice energies for various ionic substances:. Q: Lattice energy cannot be measured directly. what is its calculation based on? Choices: - chemical reactions - change in temperature - microscopic inspection - measured energy changes A:
**Answer**
measured energy changes
Q: Answer the following question given this paragraph: Streak is the color of the powder of a mineral. To do a streak test, you scrape the mineral across an unglazed porcelain plate. The plate is harder than many minerals, causing the minerals to leave a streak of powder on the plate. The color of the streak often differs from the color of the larger mineral sample ( Figure below ). Yellow-gold pyrite has a blackish streak. This blackish streak tells you that the mineral is not gold, because gold has a gold-colored streak. Q: What is the color of the powder of a mineral called? Choices: - dye - pigment - hue - streak A:
A: streak
