Answer the following question given this paragraph: HIV spreads through contact between an infected person's body fluids and another person's bloodstream or mucus membranes, which are found in the mouth, nose, and genital areas. Body fluids that may contain HIV are blood, semen, vaginal fluid, and breast milk. The virus can spread through sexual contact or shared drug needles. It can also spread from an infected mother to her baby during childbirth or breastfeeding. Saliva can carry the HIV virus, but it won't spread it, unless the saliva gets into the bloodstream. Other body fluids such as urine and sweat do not contain the virus. HIV does not spread in any fluid in which the host cells cannot survive. Q: Saliva can carry the hiv virus, but it won't spread it, unless the saliva gets into what? Choices: - lungs - kidneys - liver - bloodstream A:
bloodstream
Answer the following question given this paragraph: Humans have caused many extinctions by introducing species to new places. For example, many of New Zealand's birds have adapted to nesting on the ground. This was possible because there were no land mammals in New Zealand. Then Europeans arrived and brought cats, foxes, and other predators with them. Several of New Zealand's ground nesting birds, such as this flightless kiwi, are now extinct or threatened because of these predators. Q: What can ultimately result when species are introduced to a new place and prey on other species? Choices: - depletion - over population - elimination - extinction A:
extinction
Q: Answer the following question given this paragraph: All radioactive decay is dangerous to living things, but alpha decay is the least dangerous. Q: What is the least dangerous radioactive decay? Choices: - beta decay - gamma decay - zeta decay - alpha decay A:
A: alpha decay
Question: Answer the following question given this paragraph: The Coriolis effect describes how Earth's rotation steers winds and surface ocean currents. Unlike land, air and water move freely (in the absence of obstacles). The Coriolis effect causes the path of a freely moving object to appear to curve. This is because Earth is rotating beneath the object. So even though the object's path is straight, it appears to curve. The curve appears to be to the right in the Northern Hemisphere. It appears to be to the left in the Southern Hemisphere. Q: What effect describes how earth's rotation steers winds and surface ocean currents? Choices: - centripetal force - dorsalis - Big Bang theory - coriolis A:
Answer: coriolis

Answer the following question given this paragraph: The alkaline Earth metals include all the elements in group 2 (see Figure below ). These metals have just two valence electrons, so they are very reactive, although not quite as reactive as the alkali metals. In nature, they are always found combined with other elements. Alkaline Earth metals are silvery grey in color. They are harder and denser than the alkali metals. All are solids at room temperature. Q: Alkaline earth metals are what color? Choices: - white - black - reddish orange - silvery grey A:
(Answer)
silvery grey
