Q: Answer the following question given this paragraph: Moving water has energy ( Figure above ). That energy is used to make electricity. Hydroelectric power harnesses the energy of water moving down a stream. Hydropower is the most widely used form of renewable energy in the world. This abundant energy source provides almost one fifth of the world's electricity. The energy of waves and tides can also be used to produce water power. At this time, wave and tidal power are rare. Q: Hydroelectric power harnesses the energy of what? Choices: - weather - heat - air - water A:
A: water

Q: Answer the following question given this paragraph: A drug known as RhoGAM, short for Rh immune globulin, can temporarily prevent the development of Rh antibodies in the Rh mother, thereby averting this potentially serious disease for the fetus. RhoGAM antibodies destroy any fetal Rh+ erythrocytes that may cross the placental barrier. RhoGAM is normally administered to Rh mothers during weeks 2628 of pregnancy and within 72 hours following birth. It has proven remarkably effective in decreasing the incidence of HDN. Earlier we noted that the incidence of HDN in an Rh+ subsequent pregnancy to an Rh mother is about 1314 percent without preventive treatment. Since the introduction of RhoGAM in 1968, the incidence has dropped to about 0.1 percent in the United States. Q: Rh antibodies can prove dangerous if they cross what barrier in pregnancy? Choices: - stomach - fungal - embryo - placental A:
A: placental

Q: Answer the following question given this paragraph: CHAPTER SUMMARY 42.1 Innate Immune Response The innate immune system serves as a first responder to pathogenic threats that bypass natural physical and chemical barriers of the body. Using a combination of cellular and molecular attacks, the innate immune system identifies the nature of a pathogen and responds with inflammation, phagocytosis, cytokine release, destruction by NK cells, and/or a complement system. When innate mechanisms are insufficient to clear an infection, the adaptive immune response is informed and mobilized. Q: What serves as a first responder to pathogenic threats that bypass natural physical and chemical barriers of the body? Choices: - cells immune system - super immune system - immense immune system - innate immune system A:
A: innate immune system

Q: Answer the following question given this paragraph: Excretion is the process of removing wastes and excess water from the body. It is one of the major ways the body maintains homeostasis. Although the kidneys are the main organs of excretion, several other organs also excrete wastes. They include the large intestine, liver, skin, and lungs. All of these organs of excretion, along with the kidneys, make up the excretory system . This lesson focuses on the role of the kidneys in excretion. The roles of the other excretory organs are summarized below:. Q: Excretion is the process of removing excess water and wastes from the body. what are the main organs of excretion? Choices: - eyes - lungs - brains - kidneys A:
A: kidneys
