Answer the following question given this paragraph: Viruses , like the one depicted in Figure below , are tiny particles that may cause disease. Human diseases caused by viruses include the common cold and flu. Do you think viruses are prokaryotes or eukaryotes? The answer may surprise you. Viruses are not cells at all, so they are neither prokaryotes nor eukaryotes. Q: The common cold and flu are examples of human diseases caused by what tiny particles? Choices: - infections - parasites - bacteria - viruses A:
viruses
Answer the following question given this paragraph: A sex chromosome is a chromosome that determines the sex of an organism. Humans have two sex chromosomes, X and Y . Females have two X chromosomes ( XX ), and males have one X and one Y chromosome ( XY ). An autosome is any chromosome other than a sex chromosome. If a trait is autosomal it will affect males and females equally. Q: What chromosome determines the sex of an organism? Choices: - ribosome - S chromosome - autosome - sex chromosome A:
sex chromosome
Q: Answer the following question given this paragraph: Q: What rate is generally higher for endotherms than for ectotherms? Choices: - mortality - respiration - reproduction - metabolic A:
A: metabolic
Question: Answer the following question given this paragraph: Note the Pattern Ionic compounds contain both cations and anions in a ratio that results in zero electrical charge. In covalent compounds, electrons are shared between bonded atoms and are simultaneously attracted to more than one nucleus. In contrast, ionic compounds contain cations and anions rather than discrete neutral molecules. Ionic compounds are held together by the attractive electrostatic interactions between cations and anions. In an ionic compound, the cations and anions are arranged in space to form an extended three-dimensional array that maximizes the number of attractive electrostatic interactions and minimizes the number of repulsive electrostatic interactions (Figure 2.5 "Covalent and Ionic Bonding"). As shown in Equation 2.1, the electrostatic energy of the interaction between two charged particles is proportional to the product of the charges on the particles and inversely proportional to the distance between them: Saylor URL: http://www. saylor. org/books. Q: Ionic compounds contain cations and anions rather than what? Choices: - characterized neutral molecules - positive molecules - analogous neutral molecules - discrete neutral molecules A:
Answer: discrete neutral molecules

Answer the following question given this paragraph: Chemical energy that organisms need comes from food. The nearly universal food for life is the sugar glucose. Glucose is a simple carbohydrate with the chemical formula C 6 H 12 O 6 . The glucose molecule stores chemical energy in a concentrated, stable form. In your body, glucose is the form of energy that is carried in your blood and taken up by each of your trillions of cells. Q: Where is glucose carried in the human body? Choices: - the liver - the brain - the heart - the blood A:
**Answer**
the blood
