The Dietary Reference Intakes (DRIs) are a set of nutrition recommendations for healthy people in the United States and Canada aimed at reducing the risk of chronic disease and promoting optimal health. The DRIs for most nutrients consist of four main values. The energy-containing nutrients use different standards, including two main values. Match the DRI that corresponds with the definition given below. (Note: Each DRI can be used only once.)

a. The nutrient intake level that is estimated to meet the requirements of half of the healthy individuals in a group
b. Determined after an EAR is established. If there is no EAR, it cannot be established
c. When this is established, it means that more research needs to be done to establish more evidence-based values
d. The highest nutrient intake level likely to pose no adverse health effects to a group of people
e. The value that is predicted to maintain energy balance healthy individuals
f. This considers the proportion of all energy sources in the diet that Will decrease risk of disease

transcription is a process in which information is rewritten. it is something our cells must do, in a more specialized and narrowly defined way. in biology, transcription is the process of copying out the dna sequence of a gene in the similar alphabet of rna. it needs to happen in the nucleus because that's where the dna is. dna is always inside the nucleus unless the cell is dividing.

transcription is the first step in gene expression, which involves copying a gene's dna sequence to make an rna molecule. transcription is performed by rna polymerases. it has three stages: initiation, elongation, and termination. rna molecules must be processed after transcription in eukaryotes.

explanation:

long version:

the protein synthesis consists two processes which are, transcription and translation. transcription takes place in the nucleus. it uses dna as a template to make an rna molecule. rna then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. transcription is the first part of the central dogma of molecular biology: dna → rna. it is the transfer of genetic instructions in dna to messenger rna (mrna). during transcription, a strand of mrna is made that is complementary to a strand of dna.  

these three stages are:

  initiation: in which   is the beginning of transcription.occuring when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

    elongation: in which is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

    termination: in which is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.

name and explain one of the event that occurs during meiosis that increases the variation in offspring even more than simple reproduction?

the answer is lactic acid from anaerobic respiration. the acid in lactic acid is what creates sore and burning muscles. if you think about how acid burns that will give you a clue for questions like this.
