Answer the following question given this paragraph: The single biggest cause of the sixth mass extinction is habitat loss. A habitat is the area where a species lives and to which it has become adapted. When a habitat is disturbed or destroyed, it threatens all the species that live there with extinction. Q: What term is defined as the area where a species lives and to which it has become adapted? A:

OPTIONS:
- nature
- range
- farmland
- habitat

Answer: habitat

Problem: OPTIONS:
- reactive bond
- accretion bond
- magnetic bond
- covalent bond
Q: Answer the following question given this paragraph: You have learned that a covalent bond forms when the electron clouds of two atoms overlap with each other. In a simple H 2 molecule, the single electron in each atom becomes attracted to the nucleus of the other atom in the molecule as the atoms come closer together. An optimum distance, equal to the bond length, is eventually attained, and the potential energy reaches a minimum. A stable, single covalent bond has formed between the two hydrogen atoms. Other covalent bonds form in the same way as unpaired electrons from two atoms "match up" to form the bond. In a fluorine atom, there is an unpaired electron in one of the 2p orbitals. When a F 2 molecule forms, the 2p orbitals from each of the two atoms overlap to produce the FF covalent bond. The overlapping orbitals do not have to be of the same type. In a molecule of HF, the 1s orbital of the hydrogen atom overlaps with the 2p orbital of the fluorine atom (see Figure below ). Q: What type of bond forms by unpaired electrons from two atoms "matching up"? A:
Answer: covalent bond

Problem:OPTIONS:
- hemoglobin
- plasma cells
- antibodies
- platelets

Answer the following question given this paragraph: Blood consists of liquid plasma, which contains dissolved substances, and three types of cells: red blood cells, white blood cells, and platelets. The main function of blood is transport. Blood also fights infections, repairs tissues, controls pH, and helps regulate body temperature. Q: Red blood cells, white blood cells and what other cell is found in blood? A:
****
A: platelets

Problem:OPTIONS:
- complete loop
- closed area
- total loop
- closed loop

Answer the following question given this paragraph: Look at the battery and light bulb in Figure below . The light bulb works and it's connected to the battery, but it won't light. The problem is the loose wire on the left. It must be connected to the positive terminal of the battery in order for the bulb to light up. The reason? Electric current can flow through a material such as a wire only if the material forms a closed loop. Charges must have an unbroken path to follow between the positively and negatively charged parts of the voltage source, in this case, the battery. Q: Because charges must have an unbroken path to follow, electric current cannot flow through a material unless it forms what? A:
****
A:
closed loop
