Which statement is true?

a- there are a number of chromosomes on a given gene; all of these actively code for proteins.

b- chromosomes contain many genes; not all genes are actively coding.

c-dna contains a number of segments that code for specific proteins; these segments are chromosomes.

d- the segments of gene found on chromosomes are made of rna, which codes for protein synthesis.

B. is the correct answer because not all genes are actively coding,RNA is not code for protein synthesis, also DNA does not contain a number of segments that code for specific proteins.

The scientific method is a series of steps followed by scientific investigators to answer specific questions about the natural world. it involves making observations, formulating a hypothesis, and conducting scientific experiments.the steps of the scientific method are •observation-the first step of the scientific method involves making an observation about something that interests you•question-once you've made your observation, you must formulate a question about what you have observed. •hypothesis-once you've made your observation, you must formulate a question about what you have observed. •experiment-once you've developed a hypothesis, you must design and conduct an experiment that will test it.•results-the results are where you report what happened in the experiment. •conclusion-the final step of the scientific method is developing a conclusion.i hope that this you : )
