input with options: Answer the following question given this paragraph: By losing an electron, the sodium atom becomes a sodium ion. It now has more protons than electrons and a charge of +1. Positive ions such as sodium are given the same name as the element. The chemical symbol has a plus sign to distinguish the ion from an atom of the element. The symbol for a sodium ion is Na + . Q: Ions can be formed when atoms lose what other particles? A:
OPTIONS:
- neutrons
- protons
- shells
- electrons
output: electrons

Q: Answer the following question given this paragraph: 10.1 Overview of Muscle Tissues Muscle is the tissue in animals that allows for active movement of the body or materials within the body. There are three types of muscle tissue: skeletal muscle, cardiac muscle, and smooth muscle. Most of the body's skeletal muscle produces movement by acting on the skeleton. Cardiac muscle is found in the wall of the heart and pumps blood through the circulatory system. Smooth muscle is found in the skin, where it is associated with hair follicles; it also is found in the walls of internal organs, blood vessels, and internal passageways, where it assists in moving materials. Q: What are the three types of muscle tissue in the body? A:

OPTIONS:
- spongy, cardiac, skeletal
- topography , cardiac , smooth
- proliferating , cardiac , smooth
- skeletal, cardiac, smooth

A: skeletal, cardiac, smooth

input: OPTIONS:
- example embryology
- prenatal biology
- diversified embryology
- comparative embryology Now, answer this question: Answer the following question given this paragraph: Comparative embryology is the study of the similarities and differences in the embryos of different species. Similarities in embryos are evidence of common ancestry. All vertebrate embryos, for example, have gill slits and tails. Most vertebrates, except for fish, lose their gill slits by adulthood. Some of them also lose their tail. In humans, the tail is reduced to the tail bone. Thus, similarities organisms share as embryos may be gone by adulthood. This is why it is valuable to compare organisms in the embryonic stage. See http://www. pbs. org/wgbh/evolution/library/04/2/pdf/l_042_03. pdf for additional information and a comparative diagram of human, monkey, pig, chicken and salamander embryos. Q: What is the study of the similarities and differences in the embryos of different species? A:
A:
output: comparative embryology

Answer the following question given this paragraph: The enthalpy of the reactants is greater than the enthalpy of the products. During the course of the reaction, heat is released to the surroundings. Q: What is released during an enthalpy reaction? A:

OPTIONS:
- gold
- precipitation
- sound
- heat

Answer: heat

Problem: OPTIONS:
- moisture
- blood
- hair
- cuticle
Q: Answer the following question given this paragraph: Dermal tissue covers the outside of a plant. It's like the plant's skin. Cells of dermal tissue secrete a waxy substance called cuticle. Cuticle helps prevent water loss and damage to the plant. Q: What do cells of dermal tissue secrete? A:
Answer: cuticle

Answer the following question given this paragraph: Dermal tissue covers the outside of a plant in a single layer of cells called the epidermis. You can think of the epidermis as the plant's skin. It mediates most of the interactions between a plant and its environment. Epidermal cells secrete a waxy substance called cuticle , which coats, waterproofs, and protects the above-ground parts of plants. Cuticle helps prevent water loss, abrasions, infections, and damage from toxins. Q: What is the waxy substance that epidermal cells secrete? A:

OPTIONS:
- cellulose
- bile
- saliva
- cuticle

Answer:
cuticle
