Answer the following question given this paragraph: Hormones Maintaining homeostasis within the body requires the coordination of many different systems and organs. One mechanism of communication between neighboring cells, and between cells and tissues in distant parts of the body, occurs through the release of chemicals called hormones. Hormones are released into body fluids, usually blood, which carries them to their target cells where they elicit a response. The cells that secrete hormones are often located in specific organs, called endocrine glands, and the cells, tissues, and organs that secrete hormones make up the endocrine system. Examples of endocrine organs include the pancreas, which produces the hormones insulin and glucagon to regulate blood-glucose levels, the adrenal glands, which produce hormones such as epinephrine and norepinephrine that regulate responses to stress, and the thyroid gland, which produces thyroid hormones that regulate metabolic rates. The endocrine glands differ from the exocrine glands. Exocrine glands secrete chemicals through ducts that lead outside the gland (not to the blood). For example, sweat produced by sweat glands is released into ducts that carry sweat to the surface of the skin. The pancreas has both endocrine and exocrine functions because besides releasing hormones into the blood. It also produces digestive juices, which are carried by ducts into the small intestine. Q: In which specific organs are hormonal cells located? A:

OPTIONS:
- mammary glands
- lymph nodes
- spinal cord
- endocrine glands

Answer: endocrine glands

Problem: OPTIONS:
- the cervix
- the uterus
- the Fallopian tube
- the vulva
Q: Answer the following question given this paragraph: The external female reproductive structures are referred to collectively as the vulva. They include the labia (singular, labium), which are the "lips" of the vulva. The labia protect the vagina and urethra, both of which have openings in the vulva. Q: The external female reproductive structures are referred to collectively as what? A:
Answer: the vulva

Problem:OPTIONS:
- recycled food
- liquid diets
- biofuel
- animal-derived food

Answer the following question given this paragraph: Omnivores are animals that eat both plant- and animal-derived food. In Latin, omnivore means to eat everything. Humans, bears (shown in Figure 34.4a), and chickens are example of vertebrate omnivores; invertebrate omnivores include cockroaches and crayfish (shown in Figure 34.4b). Q: Omnivores are animals that eat both plant- and? A:
****
A: animal-derived food

Answer the following question given this paragraph: atoms held together by covalent bonds; they tend to be very hard and have high melting points. Metallic solids have unusual properties: in addition to having high thermal and electrical conductivity and being malleable and ductile, they exhibit luster, a shiny surface that reflects light. An alloy is a mixture of metals that has bulk metallic properties different from those of its constituent elements. Alloys can be formed by substituting one metal atom for another of similar size in the lattice (substitutional alloys), by inserting smaller atoms into holes in the metal lattice (interstitial alloys), or by a combination of both. Although the elemental composition of most alloys can vary over wide ranges, certain metals combine in only fixed proportions to form intermetallic compounds with unique properties. Q: An alloy is a mixture of metals that has bulk metallic properties different from those of its what? A:
OPTIONS:
- system elements
- nuclear elements
- mineral elements
- constituent elements
constituent elements

Answer the following question given this paragraph: The placenta permits a long period of fetal growth in the uterus. As a result, the fetus can become large and mature before birth. This increases its chances of surviving. Q: What allows for a large and mature fetus before birth, resulting from a long period of fetal growth in the uterus? A:
OPTIONS:
- the vagina
- the cervix
- the ovaries
- the placenta

Answer: the placenta

input with options: Answer the following question given this paragraph: Chapter 26 1 Figure 26.8 B. The diploid zygote forms after the pollen tube has finished forming, so that the male generative nuclei can fuse with the female gametophyte. 3 D 5 C 7 A 9 B 11 C 13 B 15 C 17 D 19 Both pollination and herbivory contributed to diversity, with plants needing to attract some insects and repel others. 21 The trees are adapted to arid weather, and do not lose as much water due to transpiration as non-conifers. 23 The resemblance between cycads and palm trees is only superficial. Cycads are gymnosperms and do not bear flowers or fruit. Cycads produce cones: large, female cones that produce naked seeds, and smaller male cones on separate plants. Palms do not. 25 Using animal pollinators promotes cross-pollination and increases genetic diversity. The odds that the pollen will reach another flower are greatly increased compared with the randomness of wind pollination. Q: When does the diploid zygote form? A:
OPTIONS:
- never
- before the pollen tube
- before the haploid zygote
- after the pollen tube
output:
after the pollen tube
