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.

solong [7]

Answer:

b. pass through pores in the capillary endothelium

Explanation:

The fenestrated capillaries and sinusoids have pores in their endothelium. These pores or the intracellular clefts vary in size between the fenestrated capillaries and sinusoids. Sinusoids have larger intracellular clefts. The pores serve as a passage for the movement of water-soluble substances, proteins and other substances that cannot cross the hydrophobic interior of the cell membranes.

Water-soluble hormones also cannot pass through the capillary walls. Therefore, these hormones pass through the pore or the fenestrations present in the endothelium of capillaries.

A mistake in DNA replication, in which the wrong base is placed in the growing DNA strand, can have profound effects on the desc
Klio2033 [76]

Answer:

DNA replication is the process in which the DNA is copied and it occurs during synthesis phase of the eukaryotic cell cycle. It begins with an enzyme breaking the bonds between complementary bases in DNA which exposes the bases inside  the molecules so they can be read by another enzyme and used to build two new DNA strands with complementary bases.

Explanation:

The original strand is: TAGCGTT

                                      ATCGCAA

The Mutated strand is: TGGCGTT

                                       ATCGCAA

<em>The replicated strand is: GAATCAC</em>

<em>                                           CTTAGTG</em>

15 points!!<br> What does it mean when we say that water molecules break apart?
Mama L [17]

In the case of water, hydrogen bonds form between neighboring hydrogen and oxygen atoms of adjacent water molecules. ... However, because hydrogen bonds are weaker than covalent bonds, in liquid water they form, break, and reform easily. Thus, the exact number of hydrogen bonds formed per molecule varies.
