Answer the following question given this paragraph: The genetic code works as a series of three-letter codes. Each sequence of three letters, called a triplet, corresponds to one of the twenty common amino acids. The triplets are read by the cell, one after the other, in the process of protein synthesis. The Table below shows all of the possible triplets and the amino acids that result from each three-letter code. Q: In what kind of a series does the genetic code work? Choices: - nine letter-codes - universal codes - four-letter codes - three-letter codes A:
three-letter codes
Answer the following question given this paragraph: Nuclear energy is released when the nucleus of an atom is split. Q: What kind of energy is released when the nucleus of an atom is split? Choices: - microwave - kinetic - atomic - nuclear A:
nuclear
Q: Answer the following question given this paragraph: gametes swim with the aid of their flagella to the female gametangium (the archegonium), and fertilization ensues. The zygote grows into a small sporophyte still attached to the parent gametophyte. It will give rise, by meiosis, to the next generation of spores. Liverwort plants can also reproduce asexually, by the breaking of branches or the spreading of leaf fragments called gemmae. In this latter type of reproduction, the gemmaesmall, intact, complete pieces of plant that are produced in a cup on the surface of the thallus (shown in Figure 25.11)are splashed out of the cup by raindrops. The gemmae then land nearby and develop into gametophytes. Q: Gametes swim with the aid of what structure to the female gametangium, and fertilization ensues? Choices: - oocyte - acrosome - nucleus - flagella A:
A: flagella
Question: Answer the following question given this paragraph: Acids and bases have had many uses throughout history. In this chapter we want to explore the properties of acids and bases and the reactions in which they take part. Q: Acids are the opposites of what? Choices: - water - solids - gas - bases A:
Answer: bases

Answer the following question given this paragraph: Scientists have long wanted to find the most basic building blocks of the universe. They asked, "what are the fundamental particles of matter that cannot be subdivided into smaller, simpler particles," and "what holds these particles together?" The quest for fundamental particles began thousands of years ago. Scientists thought they had finally found them when John Dalton discovered the atom in 1803 (see the timeline in Table below ). The word atom means "indivisible," and Dalton thought that the atom could not be divided into smaller, simpler particles. Q: John dalton thought that what unit, which means "indivisible", could not be divided into smaller, simpler particles? Choices: - electron - nucleus - neutron - atom A:
(A).
atom
