Answer the following question given this paragraph: A molecule of water ( Figure below ) is made of three atoms bonded together. Two of these atoms are hydrogen and one atom is oxygen. The hydrogen ions have a positive electrical charge. The oxygen atom has a negative electrical charge. The hydrogen atoms are located on one side and the oxygen atom on the other. This means that the side with the hydrogen ions has a slightly positive charge. The other side, the side without the hydrogen ions, has a slightly negative charge. The water molecule is a polar molecule . Q: What molecule is made of two hydrogen atoms and one oxygen atom? Choices: - Oxygen - carbohydrate - lipids - water A:
water

Ques: Answer the following question given this paragraph: Sponges reproduce both asexually and sexually. Asexual reproduction occurs by budding. Sexual reproduction occurs by the production of eggs and sperm. Males release sperm into the water through the osculum. Sperm may enter a female sponge through a pore and fertilize her eggs.

Answer the following question given this paragraph: The ductless endocrine glands are not to be confused with the body's exocrine system, whose glands release their secretions through ducts. Examples of exocrine glands include the sebaceous and sweat glands of the skin. As just noted, the pancreas also has an exocrine function: most of its cells secrete pancreatic juice through the pancreatic and accessory ducts to the lumen of the small intestine. Q: "endocrine" and "exocrine" are two types of what? Choices: - organs - fluids - cells - glands A:
(A).
glands
Ques:Answer the following question given this paragraph: Nutrients the body needs in relatively small amounts are called micronutrients . They include vitamins and minerals. Vitamins are organic compounds that are needed by the body to function properly. Several vitamins are described in Table below . Vitamins play many roles in good health, ranging from maintaining good vision to helping blood clot. Vitamin B12 is produced by bacteria in the large intestine. Vitamin D is synthesized by the skin when it is exposed to UV light. Most other vitamins must be obtained from foods like those listed in Table below . Q: What is the term for nutrients the body needs in relatively small amounts, including vitamins and minerals? Choices: - minor nutrients - insignificant nutrients - trace nutrients - micronutrients A:

Ans:micronutrients
