Secondary succession is a process started by an event (example forest fire) that reduces an already established ecosystem
Out of the following given choices;
contain ribose
consist of two strands
made of nucleotides
have an R group
The answer is 'made of nucleotides'. This is because out of the choices, DNA and RNA share the similarity of being made of nucleotides. However, while DNA is made of deoxyribose nucleotides, RNA is composed of ribose nucleotides. This difference is that in deoxyribose nucleotide, the 2nd carbon has a hydroxyl group while ribose nucleotide has hydrogen.
<span>The pH of the matrix increases and the pH of the inter membrane cell decreases
</span>
The reason behind this is the presence of the electron transport chain within the mitochondria which requires the transport of hydrogen ions. The movement of hydrogen ions results in varying pH. If the mitochondria dies, the hydrogen ions will not move into the matrix, causing its pH to increase, and they will build up in the inter membrane causing a decrease in pH.
Photosynthesis is when plants use sunlight to synthesize food from carbon dioxide. Plants are autotrophs (they make their own food) and the food they synthesize creates carbohydrates, so the correct answer is D - autotrophs produce carbohydrates.
Hope this helps.
