Answer the following question given this paragraph: Q: Sexual signaling molecules released by fungi are known as what? Choices: - sperm - hormones - vibrations - pheromones A:
pheromones
Answer the following question given this paragraph: The sense of taste is controlled by sensory neurons on the tongue. They are grouped in bundles called taste buds. You can see taste buds on the tongue in Figure below . Taste neurons sense chemicals in food. They can detect five different tastes: sweet, salty, sour, bitter, and umami, which is a meaty taste. When taste neurons sense chemicals, they send messages to the brain about them. The brain then decides what you are tasting. Q: Where are the taste buds located in humans? Choices: - lips - mouth - teeth - tongue A:
tongue
Q: Answer the following question given this paragraph: Hormones of the Zona Reticularis The deepest region of the adrenal cortex is the zona reticularis, which produces small amounts of a class of steroid sex hormones called androgens. During puberty and most of adulthood, androgens are produced in the gonads. The androgens produced in the zona reticularis supplement the gonadal androgens. They are produced in response to ACTH from the anterior pituitary and are converted in the tissues to testosterone or estrogens. In adult women, they may contribute to the sex drive, but their function in adult men is not well understood. In post-menopausal women, as the functions of the ovaries decline, the main source of estrogens becomes the androgens produced by the zona reticularis. Q: The deepest region of the adrenal cortex is the zona reticularis, which produces small amounts of a class of steroid sex hormones called what? Choices: - estrogen - dioxins - testosterone - androgens A:
A: androgens

Answer the following question given this paragraph: Total internal reflection allows the light to travel down the optical fiber and not pass through the sides of the tube. The light continuously reflects from the inside of the tube and eventually comes out the end. Optical fibers make interesting lamps but they are also used to transport telephone and television signals. Q: What kind of fibers are used to transport telephone and television signals? Choices: - touch fibers - process fibers - hair fibers - optical fibers A:
**Answer**
optical fibers

Answer the following question given this paragraph: Comparative embryology is the study of the similarities and differences in the embryos of different species. Similarities in embryos are evidence of common ancestry. All vertebrate embryos, for example, have gill slits and tails. Most vertebrates, except for fish, lose their gill slits by adulthood. Some of them also lose their tail. In humans, the tail is reduced to the tail bone. Thus, similarities organisms share as embryos may be gone by adulthood. This is why it is valuable to compare organisms in the embryonic stage. See http://www. pbs. org/wgbh/evolution/library/04/2/pdf/l_042_03. pdf for additional information and a comparative diagram of human, monkey, pig, chicken and salamander embryos. Q: What is the study of the similarities and differences in the embryos of different species? Choices: - example embryology - prenatal biology - diversified embryology - comparative embryology A:
**Answer**
comparative embryology
