Answer the following question given this paragraph: Another barrier is the saliva in the mouth, which is rich in lysozymean enzyme that destroys bacteria by digesting their cell walls. The acidic environment of the stomach, which is fatal to many pathogens, is also a barrier. Additionally, the mucus layer of the gastrointestinal tract, respiratory tract, reproductive tract, eyes, ears, and nose traps both microbes and debris, and facilitates their removal. In the case of the upper respiratory tract, ciliated epithelial cells move potentially contaminated mucus upwards to the mouth, where it is then swallowed into the digestive tract, ending up in the harsh acidic environment of the stomach. Considering how often you breathe compared to how often you eat or perform other activities that expose you to pathogens, it is not surprising that multiple barrier mechanisms have evolved to work in concert to protect this vital area. Q: How does lysozyme destroy bacteria? A:

OPTIONS:
- by antibiotic use
- by eating them
- by paralyzing them
- by digesting their cell walls

Answer: by digesting their cell walls

Problem: OPTIONS:
- carbonate
- nucleus
- tissue
- cellulose
Q: Answer the following question given this paragraph: Plants are multicellular eukaryotes that are placed in the Plant Kingdom . Plant cells have cell walls that are made of cellulose. Plant cells also have chloroplasts. They allow plants to make food by photosynthesis. In addition, plants have specialized reproductive organs that produce gametes. Male reproductive organs produce sperm. Female reproductive organs produce eggs. Male and female reproductive organs may be on the same plant or on different plants. Q: Plant cells have cell walls that are made of what? A:
Answer: cellulose

Problem:OPTIONS:
- a phylum
- a class
- a family
- a domain

Answer the following question given this paragraph: Prokaryotes are currently placed in two domains. A domain is the highest taxon in the classification of living things. It's even higher than the kingdom. Q: What is the highest taxon in the classification of living things? A:
****
A: a domain

Answer the following question given this paragraph: The rate of decay of carbon-14 is stable over time. Q: The rate of decay of carbon-14 does what over time? A:
OPTIONS:
- becomes unstable
- increases
- decreases
- remains stable
remains stable

Answer the following question given this paragraph: Chapter 5 1 The epidermis provides protection, the dermis provides support and flexibility, and the hypodermis (fat layer) provides insulation and padding. 3 Figure 5.6 These cells have desmosomes, which give the cells their spiny appearance. 5 D 7 C 9 C 11 D 13 B 15 A 17 C 19 C 21 C 23 B 25 The pigment melanin, produced by melanocytes, is primarily responsible for skin color. Melanin comes in different shades of brown and black. Individuals with darker skin have darker, more abundant melanin, whereas fair-skinned individuals have a lighter shade of skin and less melanin. Exposure to UV irradiation stimulates the melanocytes to produce and secrete more melanin. 27 Eccrine sweat glands are all over the body, especially the forehead and palms of the hand. They release a watery sweat, mixed with some metabolic waste and antibodies. Apocrine glands are associated with hair follicles. They are larger than eccrine sweat glands and lie deeper in the dermis, sometimes even reaching the hypodermis. They release a thicker sweat that is often decomposed by bacteria on the skin, resulting in an unpleasant odor. 29 Sweating cools the body when it becomes warm. When the body temperature rises, such as when exercising on a hot day, the dermal blood vessels dilate, and the sweat glands begin to secrete more sweat. The evaporation of the sweat from the surface of the skin cools the body by dissipating heat. 31 Acne results from a blockage of sebaceous glands by sebum. The blockage causes blackheads to form, which are susceptible to infection. The infected tissue then becomes red and inflamed. Teenagers experience this at high rates because the sebaceous glands become active during puberty. Hormones that are especially active during puberty stimulate the release of sebum, leading in many cases to blockages. Q: Acne results from a blockage of sebaceous glands by what? A:
OPTIONS:
- mucous
- progesterone
- fat
- sebum

Answer: sebum

input with options: Answer the following question given this paragraph: The experiment is a cornerstone in the scientific approach to gaining deeper knowledge about the natural world. Scientists use the principles of their hypothesis to make predictions, and then test them to see if their predictions are to be confirmed or rejected. Q: Scientists use the principles of what to make predictions, which they then test? A:
OPTIONS:
- their teachers
- their guesses
- their faith
- their hypothesis
output:
their hypothesis
