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>

Pigmented eyes (P) are dominant to non-pigmented (p), and dimpled chins (D) are dominant to Non-dimpled chins (d). A pigment-eye
Ivenika [448]

Answer:

PpDD and PpDd

Explanation:

Pigmented eyes (P) are dominant to non-pigmented (p), and dimpled chins (D) are dominant to Non-dimpled chins (d).

The <u>possible genotypes of a pigment-eyed, dimple-chinned person</u> would be  PPDD, PpDd, PPDd, PpDD while a blue-eyed person without a dimpled chin would have the genotype ppdd.

The genotype of a blue-eyed, dimpled chin child would be either of ppDd or ppDD, but in this case, the mother is ppdd and as such, the child cannot have two copies of D allele. Hence, the genotype of the child can only be ppDd.

In order for the child to have blue eyes (pp), it means that the father has to have the non-pigmented allele (p). This also means that the father is heterozygous for eye pigmentation (Pp).

<em>Hence, the genotype of the father is now limited to </em><em>PpDD</em> <em>and </em><em>PpDd</em>.

An easy way to calculate the amount of energy available at each level is to
Contact [7]

Answer:

Use the rule that 10% of the energy is transferred between layers.

Explanation:

Energy is transferred between layers of a food pyramid. That means that the  producers at the bottom of the pyramid (e.g. green plants) provide energy to the primary consumers (e.g. rabbits), which are eaten by and provide energy to the secondary consumers (e.g. foxes).

However, very little of the energy is actually transferred to the next layer, roughly 10%. So an easy way to calculate the energy available at each level is to calculate 10% of what was available from the previous level. So if there is 600 kJ available from the primary consumers, then 60 kJ are transferred to the secondary consumers

Volgvan

Answer:

South Africa, Japan, Oceania, Chile, and the Mediterranean including Sea of Marmara and Bosphorus.
