Problem: OPTIONS:
- lag
- height
- rate
- momentum
Q: Answer the following question given this paragraph: p = F nett, we can see how the change in momentum equals the average net external force multiplied by the time this force acts. The quantity F net t is given the name impulse. Impulse is the same as the change in momentum. Impulse: Change in Momentum Change in momentum equals the average net external force multiplied by the time this force acts. Q: Change in what equals the average net external force multiplied by the time this force acts? A:
Answer: momentum

Problem:OPTIONS:
- nucleus mass
- magnetic mass
- atomic mass

Answer the following question given this paragraph: The molecular mass is the sum of the masses of the atoms in the formula. Q: The sum of the masses of the atoms in the formula is referred to as what? A:
****
A: molecular mass

Answer the following question given this paragraph: Conifers Conifers are the dominant phylum of gymnosperms, with the most variety of species. Most are tall trees that usually bear scale-like or needle-like leaves. The thin shape of the needles and their waxy cuticle limits water loss through transpiration. Snow slides easily off needle-shaped leaves, keeping the load light and decreasing breaking of branches. These adaptations to cold and dry weather explain the predominance of conifers at high altitudes and in cold climates. Conifers include familiar evergreen trees, such as pines, spruces, firs, cedars, sequoias, and yews (Figure 14.20). A few species are deciduous and lose their leaves all at once in fall. The European larch and the tamarack are examples of deciduous conifers. Many coniferous trees are harvested for paper pulp and timber. The wood of conifers is more primitive than the wood of angiosperms; it contains tracheids, but no vessel elements, and is referred to as "soft wood. Q: Conifers are the dominant phylum of gymnosperms, with the most variety of species. most are tall trees that usually bear scale-like or needle-like leaves. the thin shape of the needles and their waxy cuticle limits water loss through this? A:
OPTIONS:
- evaporation
- transportation
- sedimentation
- transpiration
transpiration

Answer the following question given this paragraph: Noninfectious diseases can't be passed from one person to another. Instead, these types of diseases are caused by factors such as the environment, genetics, and lifestyle. Examples of inherited noninfectious conditions include cystic fibrosis and Down syndrome. If you're born with these conditions, you must learn how to manage the symptoms. Examples of conditions caused by environmental or lifestyle factors include heart disease and skin cancer. We can't change our genetic codes, but there are plenty of ways to prevent other noninfectious diseases. For example, cutting down on exposure to cigarette smoke and the sun's rays will prevent certain types of cancer. Q: Noninfectious diseases can't be passed from one person to another. instead, these types of diseases are caused by factors such as environment, genetics and what? A:
OPTIONS:
- weight
- education
- age
- lifestyle

Answer: lifestyle

Question: Answer the following question given this paragraph: Which of the following statements is false? a. Molecules with the formulas CH3CH2COOH and C3H6O2 could be structural isomers. Molecules must have a double bond to be cis-trans isomers. To be enantiomers, a molecule must have at least three different atoms or groups connected to a central carbon. To be enantiomers, a molecule must have at least four different atoms or groups connected to a central carbon. In triglycerides (fats and oils), long carbon chains known as fatty acids may contain double bonds, which can be in either the cis or trans configuration, illustrated in Figure 2.25. Fats with at least one double bond between carbon atoms are unsaturated fats. When some of these bonds are in the cis configuration, the resulting bend in the carbon backbone of the chain means that triglyceride molecules cannot pack tightly, so they remain liquid (oil) at room temperature. On the other hand, triglycerides with trans double bonds (popularly called trans fats), have relatively linear fatty acids that are able to. Q: What must molecules have to be cis-trans isomers? A:
OPTIONS:
- triple bond
- last bond
- single bond
- double bond
Answer: double bond

input: OPTIONS:
- vascular
- kilocalorie
- cocklebur
- nonvascular Now, answer this question: Answer the following question given this paragraph: Nonvascular plants were the first plants to evolve. Compared to other plants, their small size and lack of specialized structures, such as vascular tissue, stems, leaves, or flowers, explains why these plants evolved first. The first nonvascular plants to evolve were the liverworts. The hornworts evolved somewhat later, and mosses apparently evolved last. Of all the bryophytes, mosses are most similar to vascular plants. Presumably, they share the most recent common ancestor with vascular plants. Q: What type of plants were the first to evolve? A:
A:
output:
nonvascular
