Answer the following question given this paragraph: When gametes unite during fertilization, the resulting zygote inherits two alleles for each gene. One allele comes from each parent. The alleles an individual inherits make up the individual's genotype . The two alleles may be the same or different. As shown in Table below , an organism with two alleles of the same type ( BB or bb ) is called a homozygote . An organism with two different alleles ( Bb ) is called a heterozygote . This results in three possible genotypes. Q: When gametes unite during fertilization, the resulting zygote inherits two of what for each gene, one from each parent? A:
OPTIONS:
- chromosomes
- genomes
- molecules
- alleles

Answer: alleles

Answer the following question given this paragraph: The solubility of gases is also affected by pressure. Pressure is the force pushing against a given area. Increasing the pressure on a gas increases its solubility. Did you ever open a can of soda and notice how it fizzes out of the can? Soda contains dissolved carbon dioxide. Opening the can reduces the pressure on the gas in solution, so it is less soluble. As a result, some of the carbon dioxide comes out of solution and rushes into the air. Q: Increasing the pressure on a gas has what effect on its solubility? A:
OPTIONS:
- decrease
- halt
- slow
- increase

Answer: increase

Answer the following question given this paragraph: The Epithelial Cell Epithelial cells are typically characterized by the polarized distribution of organelles and membrane-bound proteins between their basal and apical surfaces. Particular structures found in some epithelial cells are an adaptation to specific functions. Certain organelles are segregated to the basal sides, whereas other organelles and extensions, such as cilia, when present, are on the apical surface. Cilia are microscopic extensions of the apical cell membrane that are supported by microtubules. They beat in unison and move fluids as well as trapped particles. Ciliated epithelium lines the ventricles of the brain where it helps circulate the cerebrospinal fluid. The ciliated epithelium of your airway forms a mucociliary escalator that sweeps particles of dust and pathogens trapped in the secreted mucous toward the throat. It is called an escalator because it continuously pushes mucous with trapped particles upward. In contrast, nasal cilia sweep the mucous blanket down towards your throat. In both cases, the transported materials are usually swallowed, and end up in the acidic environment of your stomach. Q: What cells are typically characterized by the polarized distribution of organelles and membrane-bound proteins between their basal and apical surfaces? A:
OPTIONS:
- mast cells
- nerve cells
- connective tissue
- epithelial cells

Answer:
epithelial cells
