Answer the following question given this paragraph: Mendeleev's table of the elements is called a periodic table because of its repeating pattern. Anything that keeps repeating is referred to as periodic. Other examples of things that are periodic include the monthly phases of the moon and the daily cycle of night and day. The term period refers to the interval between repetitions. For example, the moon's phases repeat every four weeks. In a periodic table of the elements, the periods are the rows of the table. In Mendeleev's table, each period contains eight elements, and then the pattern repeats in the next row. Q: Because of it's repeating pattern, what is mendeleev's table of the elements called? Choices: - serial chart - cycles table - phases table - periodic table A:
periodic table

Answer the following question given this paragraph: Relative dating determines which of two fossils is older or younger than the other, but not their age in years. Relative dating is based on the positions of fossils in rock layers. Lower layers were laid down earlier, so they are assumed to contain older fossils. This is illustrated in Figure below . Q: What process determines which of two fossils is older or younger than the other? Choices: - differential dating - difference dating - curve dating - relative dating A:
(Answer)
relative dating
Ques: Answer the following question given this paragraph: Explore the sea star's body plan (http://openstaxcollege. org/l/sea_star) up close, watch one move across the sea floor, and see it devour a mussel. Brittle stars belong to the class Ophiuroidea. Unlike sea stars, which have plump arms, brittle stars have long, thin arms that are sharply demarcated from the central disk. Brittle stars move by lashing out their arms or wrapping them around objects and pulling themselves forward. Sea urchins and sand dollars are examples of Echinoidea. These echinoderms do not have arms, but are hemispherical or flattened with five rows of tube feet that help them in slow movement; tube feet are extruded through pores of a continuous internal shell called a test. Sea lilies and feather stars are examples of Crinoidea. Both of these species are suspension feeders. Sea cucumbers of class Holothuroidea are extended in the oral-aboral axis and have five rows of tube feet. These are the only echinoderms that demonstrate "functional" bilateral symmetry as adults, because the uniquely extended oral-aboral axis compels the animal to lie horizontally rather than stand vertically. Q: What type of feeders are sea lilies and feather stars? Choices: - deposit feeder - bottom feeder - silt feeders - suspension feeders A:
Ans: suspension feeders

Answer the following question given this paragraph: The lifecycle of basidiomycetes includes alternation of generations (Figure 24.16). Spores are generally produced through sexual reproduction, rather than asexual reproduction. The club-shaped basidium carries spores called basidiospores. In the basidium, nuclei of two different mating strains fuse (karyogamy), giving rise to a diploid zygote that then undergoes meiosis. The haploid nuclei migrate into basidiospores, which germinate and generate monokaryotic hyphae. The mycelium that results is called a primary mycelium. Mycelia of different mating strains can combine and produce a secondary mycelium that contains haploid nuclei of two different mating strains. This is the dikaryotic stage of the basidiomyces lifecyle and and it is the dominant stage. Eventually, the secondary mycelium generates a basidiocarp, which is a fruiting body that protrudes from the groundthis is what we think of as a mushroom. The basidiocarp bears the developing basidia on the gills under its cap. Q: Spores are generally produced through what type of reproduction? Choices: - similar - asexual - hormone - sexual A:
(A).
sexual
Ques:Answer the following question given this paragraph: Skepticism is an attitude of doubt about the truthfulness of claims that lack empirical evidence. Scientific skepticism , also referred to as skeptical inquiry, questions claims based on their scientific verifiability rather than simply accepting claims based on faith or anecdotes. Scientific skepticism uses critical thinking to analyze such claims and opposes claims which lack scientific evidence. Q: What is an attitude of doubt about the truthfulness of claims that lack empirical evidence? Choices: - conspiracy - speculation - independent variable - skepticism A:

Ans:skepticism
Question: Answer the following question given this paragraph: Water is involved in many other biochemical reactions. As a result, just about all life processes depend on water. Clearly, life as we know it could not exist without water. Q: Nearly all life processes depend on what substance, which is involved in biochemical reactions? Choices: - food - hydrocarbons - air - water A:
Answer:
water
