Answer the following question given this paragraph: 6.1 | The Genome By the end of this section, you will be able to: Describe the prokaryotic and eukaryotic genome Distinguish between chromosomes, genes, and traits The continuity of life from one cell to another has its foundation in the reproduction of cells by way of the cell cycle. The cell cycle is an orderly sequence of events in the life of a cell from the division of a single parent cell to produce two new daughter cells, to the subsequent division of those daughter cells. The mechanisms involved in the cell cycle are highly conserved across eukaryotes. Organisms as diverse as protists, plants, and animals employ similar steps. Q: What do we call the orderly sequence of events in the life of a cell from the division of a single parent cell to produce two new daughter cells, to the subsequent division of those daughter cells? Choices: - cell death - cell replication - circadian cycle - cell cycle A:
cell cycle

Answer the following question given this paragraph: Two interesting properties of liquids are surface tension and viscosity. Q: Surface tension and viscosity are generally associated with what form or state of matter? Choices: - solids - gases - electrons - liquids A:
(Answer)
liquids
Ques: Answer the following question given this paragraph: Bases are ionic compounds that produce negative hydroxide ions (OH - ) when dissolved in water. An ionic compound contains positive metal ions and negative nonmetal ions held together by ionic bonds. (Ions are atoms that have become charged particles because they have either lost or gained electrons. ) An example of a base is sodium hydroxide (NaOH). When it dissolves in water, it produces negative hydroxide ions and positive sodium ions (Na + ). This can be represented by the equation:. Q: What are the ionic compounds that produce negative hydroxide ions when dissolved in water? Choices: - isotopes - acids - enzymes - bases A:
Ans: bases

An ecosystem is made of the biotic and abiotic factors in an area. Q: What includes the living organisms in an area and the non-living aspects of the environment? Choices: - outpost - habitat - degradation - ecosystem A:
(A).
ecosystem
Ques:Answer the following question given this paragraph: The Evolution of Promoters The evolution of genes may be a familiar concept. Mutations can occur in genes during DNA replication, and the result may or may not be beneficial to the cell. By altering an enzyme, structural protein, or some other factor, the process of mutation can transform functions or physical features. However, eukaryotic promoters and other gene regulatory sequences may evolve as well. For instance, consider a gene that, over many generations, becomes more valuable to the cell. Maybe the gene encodes a structural protein that the cell needs to synthesize in abundance for a certain function. If this is the case, it would be beneficial to the cell for that gene's promoter to recruit transcription factors more efficiently and increase gene expression. Scientists examining the evolution of promoter sequences have reported varying results. In part, this is because it is difficult to infer exactly where a eukaryotic promoter begins and ends. Some promoters occur within genes; others are located very far upstream, or even downstream, of the genes they are regulating. However, when researchers limited their examination to human core promoter sequences that were defined experimentally as sequences that bind the preinitiation complex, they found that promoters evolve even faster than protein-coding genes. It is still unclear how promoter evolution might correspond to the evolution of humans or other higher organisms. However, the evolution of a promoter to effectively make more or less of a given gene product [1] is an intriguing alternative to the evolution of the genes themselves. Promoter Structures for RNA Polymerases I and III In eukaryotes, the conserved promoter elements differ for genes transcribed by RNA polymerases I, II, and III. RNA polymerase I transcribes genes that have two GC-rich promoter sequences in the -45 to +20 region. These sequences alone are sufficient for transcription initiation to occur, but promoters with additional sequences in the region from -180 to -105 upstream of... Q: When can mutations occur in genes? Choices: - after rna replication - after dna replication - during rna replication - during dna replication A:

Ans:during dna replication
