input: OPTIONS:
- chlorophyll
- enzymes
- cytoplasmic acid
- salicylic acid Now, answer this question: Answer the following question given this paragraph: Plants don't have immune systems, but they do respond to disease. Typically, their first line of defense is the death of cells surrounding infected tissue. This prevents the infection from spreading. Many plants also produce hormones and toxins to fight pathogens. For example, willow trees produce salicylic acid to kill bacteria. The same compound is used in many acne products for the same reason. Exciting new research suggests that plants may even produce chemicals that warn other plants of threats to their health, allowing the plants to prepare for their own defense. As these and other responses show, plants may be rooted in place, but they are far from helpless. Q: What do willow trees produce to kill bacteria? A:
A:
output: salicylic acid

Answer the following question given this paragraph: When humans reproduce, there are two parents involved. DNA must be passed from both the mother and father to the child. Humans cannot reproduce with just one parent; humans can only reproduce sexually. But having just one parent is possible in other eukaryotic organisms, including some insects, fish, and reptiles. These organisms can reproduce asexually, meaning the offspring ("children") have a single parent and share the exact same genetic material as the parent. This is very different from reproduction in humans. Bacteria, being a prokaryotic, single-celled organism, must reproduce asexually. Q: What type of reproduction produces offspring from a single parent that share the exact same genetic material as the parent? A:

OPTIONS:
- mutation
- microscopic reproduction
- sexual reproduction
- asexual reproduction

Answer: asexual reproduction

Problem: OPTIONS:
- human growth hormone
- amino acid
- dopamine
- human lysozyme
Q: Answer the following question given this paragraph: Q: Which antibacterial protein is found in tears and saliva? A:
Answer: human lysozyme

Problem:OPTIONS:
- gravity
- momentum
- energy
- wavelength

Answer the following question given this paragraph: Sound, like all waves, travels at a certain speed and has the properties of frequency and wavelength. You can observe direct evidence of the speed of sound while watching a fireworks display. The flash of an explosion is seen well before its sound is heard, implying both that sound travels at a finite speed and that it is much slower than light. You can also directly sense the frequency of a sound. Perception of frequency is called pitch. The wavelength of sound is not directly sensed, but indirect evidence is found in the correlation of the size of musical instruments with their pitch. Small instruments, such as a piccolo, typically make high-pitch sounds, while large instruments, such as a tuba, typically make low-pitch sounds. High pitch means small wavelength, and the size of a musical instrument is directly related to the wavelengths of sound it produces. So a small instrument creates short-wavelength sounds. Similar arguments hold that a large instrument creates long-wavelength sounds. The relationship of the speed of sound, its frequency, and wavelength is the same as for all waves:. Q: Sound, like all waves, travels at a certain speed and has the properties of frequency and this? A:
****
A: wavelength

Answer the following question given this paragraph: All cells, including both plant and animal cells, need energy for processes such as active transport. How do cells obtain the energy they need?. Q: All cells need what for processes like active transport? A:
OPTIONS:
- hydrogen
- sunlight
- oxygen
- energy
energy

Answer the following question given this paragraph: The depression that allows water to collect to form a lake may come about in a variety of ways. The Great Lakes, for example, are glacial lakes. A glacial lake forms when a glacier scrapes a large hole in the ground. When the glacier melts, the water fills the hole and forms a lake. Over time, water enters the lake from the sources mentioned above as well. Q: What forms when a glacier scrapes a large hole in the ground? A:
OPTIONS:
- frozen lake
- drift lake
- melting lake
- glacial lake

Answer:
glacial lake
