Ques: Answer the following question given this paragraph: Figure 10.4 Double-stranded DNA wraps around histone proteins to form nucleosomes that have the appearance of "beads on a string. " The nucleosomes are coiled into a 30-nm chromatin fiber. When a cell undergoes mitosis, the chromosomes condense even further. Q: Double strands of what wrap around histone proteins to form nucleosomes, which are coiled into a chromatin fiber? Choices: - bacteria - ribosomes - chromatids - dna A:
Ans: dna
(Q).
Answer the following question given this paragraph: Figure 11.35 (a) Capillary action depends on the radius of a tube. The smaller the tube, the greater the height reached. The height is negligible for large-radius tubes. (b) A denser fluid in the same tube rises to a smaller height, all other factors being the same. Q: What domain-level category of cells can contain more than 1000 times the dna found in a typical bacterial cell? Choices: - chromosomes - mutations - genetic - eukaryotic A:
(A).
eukaryotic
Ques:Answer the following question given this paragraph: A Geiger counter provides a sensitive means of detecting radioactivity. A tube is filled with an inert gas, which will conduct electricity when radiation enters it. When a charged particle comes into the tube, it changes the electrical potential between the anode and the cathode. This change in potential in the tube produces a change in voltage in the electrical circuit and registers as a count. Geiger counters are fairly inexpensive and reliable, so they are useful in a wide range of applications. More complicated types of counters are also available, but are generally used in sophisticated experiments. Q: What counter provides a sensitive means of detecting radioactivity? Choices: - calorie - bouncy - gravity - geiger A:

Ans:geiger
Answer the following question given this paragraph: Some animal-like protists use their "tails" to eat. These protists are called filter-feeders . They acquire nutrients by constantly whipping their tails, called flagellum , back and forth. The whipping of the flagellum creates a current that brings food into the protist. Q: Protists which use their tails to eat are called what? Choices: - swimmers - cycle - feeders - flagellators - filter-feeders A:
filter-feeders
