Ques: Answer the following question given this paragraph: Some of the specialized cells grow short, sharp projections called spicules. Spicules make up the sponge's internal skeleton, or endoskeleton. The endoskeleton helps to support and protect the sponge. Q: What are the sharp projections that specialized cells grow called? Choices: - ossicles - cilia - antlers - spicules A:
Ans: spicules

Answer the following question given this paragraph: The disintegration of unstable nuclei does not occur all at once. The rate of disintegration is a statistical process. The most convenient way to consider it is by a concept known as half-life . The time required for half of the atoms in any given quantity of a radioactive substance to decay is the half-life of that element. Each particular isotope has its own half-life. For example, the half-life of radium-226 is 1600 years. That is, beginning with 1.00 gram of radium-226, it would take 1600 years for half of it to decay and leave 0.50 gram remaining. After another 1600 years, only 0.25 gram would remain. In each half-life, exactly half of the beginning amount decays. Q: What is the time it takes for radioactive substance to decay? Choices: - decay rate - full-life - deterioration rate - half-life A:
(A).
half-life
Ques:Answer the following question given this paragraph: Eudicots Eudicots, or true dicots, are characterized by the presence of two cotyledons. Veins form a network in leaves. Flower parts come in four, five, or many whorls. Vascular tissue forms a ring in the stem. (In monocots, vascular tissue is scattered in the stem. ) Eudicots can be herbaceous (like dandelions or violets), or produce woody tissues. Most eudicots produce pollen that is trisulcate or triporate, with three furrows or pores. The root system is usually anchored by one main root developed from the embryonic radicle. Eudicots comprise two-thirds of all flowering plants. Many species seem to exhibit characteristics that belong to either group; therefore, the classification of a plant as a monocot or a eudicot is not always clearly evident (Table 14.1). Q: The root system is usually anchored by one main root developed from what? Choices: - sperm radicle - nuclei radicle - organisms radicle - embryonic radicle A:

Ans:embryonic radicle
Ques: Answer the following question given this paragraph: Transparent matter is matter that transmits light without scattering it. Examples of transparent matter include air, pure water, and clear glass. You can see clearly through a transparent object, such as the revolving glass doors in the figure, because all the light passes straight through it. Q: What type of matter transmits light without scattering it? Choices: - translucent - clean - bioluminescent - transparent A:
Ans:
transparent
