In two or more complete sentences describe how a dam placed in a river can act as both a constructive and destructive force.
FromTheMoon [43]
The good thing about a dam is that electricity can be created by mechanical means. That does not affect the atmosphere. Storing such production is a different matter.

The bad thing about a dam is that it wreaks havoc on the land where the water is stored behind the dam.

Use mitochondrion in a sentence
olga nikolaevna [1]
Mitochondrion a singular word for mitochondria is a "powerhouse" organelle of the cell.

<span>Mitochondrion is an important organelle in most living organisms because it is where biochemical processes of living organisms such as respiration takes place. The mitochondrion has a smooth outer membrane but a larger inner membrane. The inner membrane is about 70% protein and is very convoluted because that can even fit inside the outer membrane. Mitochondrion is the carrier of the Kreb's cycle in the matrix and it is responsible for the transfer of electron chain found in the cristae of the inner membrane.</span>

g The pH of the space between the inner and outer mitochondrial membrane is ______________ the pH of the mitochondrial matrix.
AURORKA [14]

Answer:

lower than

Explanation:

The protons obtained from the spit of  hydrogen atoms, to protons and electrons, (which was transported to the Matrix of the mitochondria by NADH and FADH2 ) are pumped by PMF into the intramembrane space.

The constant pumps by the PMF,due to the electron transport chains set up high concentration of Hydrogen ions in the intramembrane space.If pH is -log[H+] then the high the number of H+/protons,the stronger  the acidity,and lower the pH  of the medium.

This set up higher electrochemical gradient compare to the matrix.Thus H+ diffuses down the gradients into the matrix.

This generate energy needed for the synthesis of ATPs by ATPase synthase in the matrix
