What are DRIs and why are they preferred? Why are they not on food labels?
Pie

DRIs is the general term for a set of reference values or guidelines that are used to plan and asses nutrient intakes of healthy people. These values which vary by age and gender include: 

- Recommended Dietary allowance (RDA): average daily level of intake sufficient to meet nutrient requirements of about 97 - 98% of healthy people.

-Adequate intake (AI): established when evidence is not sufficient to develop an RDA and is set at a level assumed to ensure nutritional adequacy.

- Tolerable Upper Intake (UL): Maximum daily intake unlikely to cause adverse health  effects.

DRIs are not necessarily found on labels because there is no law requiring that they must be placed there.

Why would there be a relationship between photosynthesis and temperature<br><br> Help me
Mumz [18]

Answer:

Enzyme-controlled chemical reactions combining carbon dioxide and glucose water. The photosynthetic rate is affected by the temperature much like any other enzyme-controlled reaction.

Explanation:

At low temperatures, the number of molecular collisions between enzymes and substrates limits the photosynthetic rate. Enzymes are denatured at high temperatures.

Enzymes are protein molecules used in biological reactions by living organisms. The proteins are folded in a very specific form, which enables them to effectively bind to the molecules of interest. The enzymes used for photosynthesis perform less efficiently at a low temperature between 32 and 50 degrees Fahrenheit 0, 10, and 10 degrees Celsius, which lowers the photosynthesis rate.This will lead to lower glucose synthesis and slow growth. In the case of plants in a greenhouse, this is prevented by installing a greenhouse heater and thermostat.

What are some functions of noncoding DNA?
Artyom0805 [142]

Answer:

Explanation:

The non-coding DNA sequences forms the part of the organism's DNA. It is the part of the human genome which does not encode for any protein sequence. Some of the non-coding DNA may be transcribed into into any of the functional non-coding RNA molecules such as ribosomal RNA, transfer RNA and regulatory RNA. Other functions of the non-coding DNA involve translational and transcriptional regulation of the protein coding sequences, origin of DNA replication process, scaffold attachment, telomeres and centromeres.
