Answer:

Barrier islands form in three ways. They can form from spits, from drowned dune ridges or from sand bars. Longshore drift is the movement of sand parallel to the shore caused by the angle of the waves breaking on the beach. When a storm such as a hurricane digs an inlet through the spit a barrier island is formed. Barrier islands are a specific type of island that lie parallel to the coastline of a larger mainland. They are separated from shore by a bay, lagoon or sound and because of where they are situated, they protect the coast from being directly impacted by storm waves or winds.

f(T) = 0.485 ≅ 0.48

f(t) = 0.515 ≅ 0.52

b. Determine the genotype frequencies of the exposed generation

F (TT) = 0.21
F (Tt) = 0.55
F (tt) = 0.24

the genotype frequencies of the next generation

F(TT) = 0.23
F(Tt) = 0.5

umka2103 [35]

Answer: The answer is D - Intramembrane space in mitochondria; high

Explanation:

Mitochondria is an organelle in the cell, it is known as the power House of the cell because of its role in the storage and production of energy. During electron transport chain the proton pumps generate a proton gradient which is stored in form of energy.

During proton pumping and electron transfer the electrons are passed down the chain from the matrix to the inter membrane of the mitochondria. The electrons move from higher concentration of level to lower energy level. Some of these are used to pump Hydrogen ions (H+), moving them out of the matrix into the inter membrane space.

The Intramembrane space of the mitochondria therefore has a a high concentration of Hydrogen ions (H+).

I hope this helps.
