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:
placental

Answer the following question given this paragraph: Polarization leads to the buildup of electric charges on objects. This buildup of charges is known as static electricity . Once an object becomes charged, it is likely to remain charged until another object touches it or at least comes very close to it. That's because electric charge cannot travel easily through air, especially if the air is dry. Q: What leads to the buildup of electric charges on objects? Choices: - movement - gravity - rotation - polarization A:
(Answer)
polarization
Ques: Answer the following question given this paragraph: Angiosperms are seed plants that produce seeds in the ovaries of flowers. Today, they are by far the most diverse type of seed plants. In fact, the vast majority of all modern plants are angiosperms. There are hundreds of thousands of species of them. The apple tree in Figure below is an example of a common angiosperm. Q: Seed plants that produce seeds in the ovaries of their flowers are known as what? Choices: - conifers - gymnosperms - spores - angiosperms A:
Ans: angiosperms
(Q).

Ques:Answer the following question given this paragraph: Solutions can also be comprised of a solid solute and a liquid solvent. These interactions are governed by the same three interactions we discussed earlier: polar-polar, nonpolar-polar, and nonpolar-nonpolar. The Table below describes these interactions. Q: What is the name of the liquid component of a solution? Choices: - ionic - reactant - solute - solvent A:

Ans:solvent
Answer the following question given this paragraph: Bonds break and reform during chemical reactions. Reactants and products contain the same atoms, but they are rearranged during the reaction, so reactants and products are different substances. Q: In a chemical reaction, what, in general, comes together in order to form a product? Choices: - gases - liquids - propellants - reactants A:
reactants
