Answer the following question given this paragraph: Puberty in girls starts when the hypothalamus "tells" the pituitary gland to secrete hormones that target the ovaries. Two pituitary hormones are involved: luteinizing hormone (LH) and follicle-stimulating hormone (FSH) . These hormones stimulate the ovary to produce estrogen . Estrogen, in turn, promotes growth and other physical changes of puberty. It stimulates growth and development of the internal reproductive organs, breasts, and pubic hair (see Figure below ). You can watch an animation of these and other changes that girls experience during puberty at this link: http://www. bbc. co. uk/science/humanbody/body/interactives/lifecycle/teenagers/ . Q: What item starts puberty in girls? Choices: - the ovary - the uterus - the thyroid - the hypothalamus A:
the hypothalamus
Q: Answer the following question given this paragraph: Cutting and burning trees to clear land for farming is called slash-and-burn agriculture. How does this affect the atmosphere?. Q: What is the cutting and burning trees to clear land for farming called? Choices: - drop-and-blaze agriculture - cut-and-smoke farming - reduce-and-ignite agriculture - slash-and-burn agriculture A:
A: slash-and-burn agriculture
Question: Answer the following question given this paragraph: You couldn't survive without your skin. It has many important functions. In several ways, it helps maintain homeostasis. The main function of the skin is controlling what enters and leaves the body. It prevents the loss of too much water from the body. It also prevents bacteria and other microorganisms from entering the body. Melanin in the epidermis absorbs ultraviolet light. This prevents the light from reaching and damaging the dermis. Q: What is the largest organ of the human body? Choices: - your lungs - your brain - your blood - your skin A:
Answer: your skin

Answer the following question given this paragraph: Type 1 diabetes occurs when the immune system attacks normal cells of the pancreas. Since the cells in the pancreas are damaged, the pancreas cannot make insulin. Type 1 diabetes usually develops in childhood or adolescence. Q: Type 1 diabetes results in the pancreas not being able to make what ? Choices: - hemoglobin - sugar - glucose - insulin A:

Answer the following question given this paragraph: saliva. Although there may be a tendency to think that mechanical digestion is limited to the first steps of the digestive process, it occurs after the food leaves the mouth, as well. The mechanical churning of food in the stomach serves to further break it apart and expose more of its surface area to digestive juices, creating an acidic "soup" called chyme. Segmentation, which occurs mainly in the small intestine, consists of localized contractions of circular muscle of the muscularis layer of the alimentary canal. These contractions isolate small sections of the intestine, moving their contents back and forth while continuously subdividing, breaking up, and mixing the contents. By moving food back and forth in the intestinal lumen, segmentation mixes food with digestive juices and facilitates absorption. In chemical digestion, starting in the mouth, digestive secretions break down complex food molecules into their chemical building blocks (for example, proteins into separate amino acids). These secretions vary in composition, but typically contain water, various enzymes, acids, and salts. The process is completed in the small intestine. Food that has been broken down is of no value to the body unless it enters the bloodstream and its nutrients are put to work. This occurs through the process of absorption, which takes place primarily within the small intestine. There, most nutrients are absorbed from the lumen of the alimentary canal into the bloodstream through the epithelial cells that make up the mucosa. Lipids are absorbed into lacteals and are transported via the lymphatic vessels to the bloodstream (the subclavian veins near the heart). The details of these processes will be discussed later. In defecation, the final step in digestion, undigested materials are removed from the body as feces. Q: Mechanical churning of food in what organ serves to further break it apart and expose more of its surface area to digestive juices, creating an acidic "soup" called chyme? Choices: - liver - kidneys - gall bladder - stomach A:
**Answer**
stomach
