Tails of the phospholipids in the phospholipid bilayer are hydrophobic, consisting of fatty acid chains.
<span>Phospholipids are composed of two fatty acids, glycerol and phosphate groups, forming an amphipathic molecule. Amphipathic molecules are built from hydrophilic (water-loving) and hydrophobic (not attracted to water) molecules. The phospholipids in the plasma membrane are arranged in two layers, called a phospholipid bilayer. Hydrophobic molecules (fatty acids) are on the interior of the membrane, whereas the water-loving heads (phosphate head) point outwards, toward either the cytoplasm or the fluid that surrounds the cell. The head group and fatty acids are attached <span>to </span>a glycerol unit.</span>
Answer: Option C
Explanation: The balanced chemical equation that explains photosynthesis is stated below:
6CO2(g) + 6H20(g) --------> C6H12O6 + 6O2(g) + energy (in from of ATP)
From the equation, 6 atoms of carbon C are contained in 6 moles of atmospheric Carbondioxide CO2, that reacted with 6 moles of water molecules H2O, contained in plant cells to yield 1 mole of glucose C6H12O6 and chemical energy in the form of ATP (adenosine triphosphate)
During sexual reproduction, two haploid gametes join in the process of fertilization to produce a diploid zygote.

1 is most likely mutation
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.
