Answer the following question given this paragraph: Figure 6.20 Vitamins are important coenzymes or precursors of coenzymes, and are required for enzymes to function properly. Multivitamin capsules usually contain mixtures of all the vitamins at different percentages. Q: What are important coenzymes or precursors of coenzymes, and are required for enzymes to function properly? A:

OPTIONS:
- carbohydrates
- supplements
- Drugs
- vitamins

Answer: vitamins

Problem: OPTIONS:
- outsider effect
- pioneer effect
- novelty effect
- founder effect
Q: Answer the following question given this paragraph: Founder effect occurs when a few individuals start, or found, a new population. By chance, allele frequencies of the founders may be different from allele frequencies of the population they left. An example is described in Figure below . Q: What occurs when a few individuals start, or found, a new population? A:
Answer: founder effect

Problem:OPTIONS:
- newly created elements
- newly developed orbits
- expanded pathways
- newly created orbitals

Answer the following question given this paragraph: When atomic orbitals hybridize, the valence electrons occupy the newly created orbitals. The Be atom had two valence electrons, so each of the sp orbitals gets one of these electrons. Each of these electrons pairs up with the unpaired electron on a chlorine atom when a hybrid orbital and a chlorine orbital overlap during the formation of the BeCl bonds. Q: When atomic orbitals hybridize, the valence electrons occupy these? A:
****
A: newly created orbitals

Answer the following question given this paragraph: Reconnection After speciation, two species may recombine or even continue interacting indefinitely. Individual organisms will mate with any nearby individual who they are capable of breeding with. An area where two closely related species continue to interact and reproduce, forming hybrids, is called a hybrid zone. Over time, the hybrid zone may change depending on the fitness of the hybrids and the reproductive barriers (Figure 18.22). If the hybrids are less fit than the parents, reinforcement of speciation occurs, and the species continue to diverge until they can no longer mate and produce viable offspring. If reproductive barriers weaken, fusion occurs and the two species become one. Barriers remain the same if hybrids are fit and reproductive: stability may occur and hybridization continues. Q: What term means an area where two closely related species continue to interact and reproduce? A:
OPTIONS:
- homozone
- heterozone
- common zone
- hybrid zone
hybrid zone

Answer the following question given this paragraph: A circuit that consists of two loops is called a parallel circuit. If one loop of a parallel circuit is interrupted, current can still flow through the other loop. Q: A circuit that consists of two loops is called a what? A:
OPTIONS:
- diverse circuit
- unnatural circuit
- complex circuit
- parallel circuit

Answer:
parallel circuit
