Q: The three types of mammals are characterized by their method of what? Read this paragraph and choose the correct option from the provided answers: There are three types of mammals, characterized by their method of reproduction. All mammals, except for a few, are viviparous , meaning they produce live young instead of laying eggs. The monotremes , however, have birdlike and reptilian characteristics, such as laying eggs and a cloaca. An example of a monotreme is the platypus with its birdlike beak and egg-laying characteristics. The echidnas are the only other monotreme mammals. A second type of mammal, the marsupial mammal, includes kangaroos, wallabies, koalas and possums. These mammals give birth to underdeveloped embryos, which then climb from the birth canal into a pouch on the front of the mother's body, where it feeds and continues to grow. The remainder of mammals, which is the majority of mammals, are placental mammals. These mammals develop in the mother's uterus, receiving nutrients across the placenta. Placental mammals include humans, rabbits, squirrels, whales, elephants, shrews, and armadillos. Dogs and cats, and sheep, cattle and horses are also placental mammals. Choices: - specializaiton - differentiation - pattern - reproduction A:
reproduction

Q: Q: Untreated chlamydia can lead to pelvic inflammatory disease, which affects what organ system? Read this paragraph and choose the correct option from the provided answers: Symptoms of chlamydia may include a burning sensation during urination and a discharge from the vagina or penis. Chlamydia can be cured with antibiotics , but often there are no symptoms, so people do not seek treatment. Untreated chlamydia can lead to more serious problems, such as pelvic inflammatory disease (PID) . This is an infection of the uterus, fallopian tubes, and/or ovaries. It can scar a woman's reproductive organs and make it difficult for her to become pregnant. Choices: - endocrine system - nervous system - circulatory system - female reproductive system A:
A: female reproductive system

Question: Q: The reproductive tissues of male and female humans develop similarly in utero until a low level of the hormone testosterone is released from male what? Read this paragraph and choose the correct option from the provided answers: Human Reproductive Anatomy The reproductive tissues of male and female humans develop similarly in utero until a low level of the hormone testosterone is released from male gonads. Testosterone causes the undeveloped tissues to differentiate into male sexual organs. When testosterone is absent, the tissues develop into female sexual tissues. Primitive gonads become testes or ovaries. Tissues that. Choices: - kidneys - liver - bladder - gonads A:
Answer: gonads

Q: Rain dissolves fertilizer in the soil, what carries it away? Read this paragraph and choose the correct option from the provided answers: Rain dissolves fertilizer in the soil. Runoff carries it away. The fertilizer ends up in bodies of water, from ponds to oceans. Nitrogen is a fertilizer in the water. Since there is a lot of nitrogen, it causes algae to grow out of control. Pictured below is a pond covered with algae ( Figure below ). Algae use up carbon dioxide in the water. After the algae die, decomposers break down the dead tissue. The decomposers use up all the oxygen in the water. This creates a dead zone. A dead zone is an area in a body of water where nothing grows because there is too little oxygen. There is a large dead zone in the Gulf of Mexico ( Figure below ). The U. S. states outlined on the map have rivers that drain into the Gulf of Mexico. The rivers drain vast agricultural lands. The water carries fertilizer from these areas into the Gulf. Choices: - carbon ? - fossils - clouds - runoff? A:
**Answer**
runoff?

Q: Q: Regulatory proteins bind to regulatory elements to control what? Read this paragraph and choose the correct option from the provided answers: Regulation of Transcription. Regulatory proteins bind to regulatory elements to control transcription. The regulatory elements are embedded within the DNA. Choices: - mutation - differentiation - growth - transcription A:
A: transcription
