Answer the following question given this paragraph: Atomic Number In the 1910s, experiments with X rays led to this useful conclusion: the magnitude of the positive charge in the nucleus of every atom of a particular element is the same. In other words, all atoms of the same element have the same number of protons. Furthermore,. Q: All atoms of the same element have the same number of what? Choices: - electrons - molecules - charge - protons A:
protons
Answer the following question given this paragraph: The ileum is the third part of the small intestine. A few remaining nutrients are absorbed here. Like the jejunum, the inner surface of the ileum is covered with villi that increase the surface area for absorption. Q: The site of some nutrient absorption, the ileum is the third part of what digestive organ? Choices: - stomach - large intestine - rectum - small intestine A:
small intestine
Q: Answer the following question given this paragraph: Solar cells convert the energy in sunlight to electrical energy. Solar cells are also called photovoltaic (PV) cells because they use light ( photo- ) to produce voltage ( -voltaic ). Solar cells contain a material such as silicon that absorbs light energy. The energy knocks electrons loose so they can flow freely and produce a difference in electric potential energy, or voltage. The flow of electrons creates electric current. Solar cells have positive and negative contacts, like the terminals in chemical cells. If the contacts are connected with wire, current flows from the negative to positive contact. The Figure below and following URL show how a solar cell works. http://www. suntreksolar. com/solarElectricity/howCellsWork. asp. Q: Solar cells convert the energy in sunlight to what type of energy? Choices: - active energy - radical energy - stellar energy - electrical energy A:
A: electrical energy
Question: Answer the following question given this paragraph: Mammals have separate sexes and reproduce sexually. They produce eggs or sperm and must mate in order for fertilization to occur. A few mammals are oviparous. They lay eggs, which later hatch. These mammals are called monotremes. Most mammals are viviparous and give birth to live young. These mammals are either placental mammals or marsupials. Placental mammals give birth to relatively large and well-developed fetuses. Marsupials give birth to smaller, less-developed embryos. In both placental and marsupial mammals, the young grow and develop inside the mother's body in an organ called the uterus. At birth, they pass through a tube-like organ called the birth canal, or vagina. Q: Mammals that lay eggs are called what? Choices: - viviparous - herbivores - marsupial - monotremes A:
Answer: monotremes
*Question*
Answer the following question given this paragraph: diploid cell that forms when two haploid gametes unite during fertilization. Q: When two haploid gametes unite during fertilization they form what? Choices: - a mutated cell - haploid cell - a fertilized cell - a diploid cell A:
**Answer**
a diploid cell

Answer the following question given this paragraph: All volcanoes share the same basic features. First, mantle rock melts. The molten rock collects in magma chambers that can be 160 kilometers (100 miles) beneath the surface. As the rock heats, it expands. The hot rock is less dense than the surrounding rock. The magma rises toward the surface through cracks in the crust. A volcanic eruption occurs when the magma reaches the surface. Lava can reach the surface gently or explosively. Q: When magma reaches the surface through cracks in the earth's crust, what occurs? Choices: - volcanic explosion - magma eruption - tsunami - volcanic eruption A:
(Answer)
volcanic eruption
