Females have two X chromosomes while males have one X and one Y chromosome
Answer:
The pH remains constant
Explanation:
The pH value of Mitochondrial matrix = 7.8 while the pH of the intermembrane space of the mitochondria = 7.0–7.4
The presence of the hydrogen atoms makes the mitochondrial matrix acidic and hence reduced the pH value but the pH of inner and outer matrix is maintained equal to each other thus as the H+ ion increases, the base concentration increases thereby pushing H+ to the inter membrane space and hence producing ATP.
The answer is B , i hope this helps
First question is - Why do we have limestone? Formed from this type of sediment are biological sedimentary rocks. Their biological organ is often revealed in the rock fossils. Some limestones can form by direct precipitation of calcium carbonate from marine or fresh water. (The second question is) - What do iron bands mean? The rocks are "banded" because the iron minerals deposited in alternating bands with silica and sometimes shale. The banding might have resulted from seasonal changes in organism activity steel mill. Most iron ore is used to make steel. Here a steel slab is being cut to length in a steel mill.
Answer:
Both plant and animal cells have a nucleus, where DNA replication takes place. Both plant and animal cells have cell walls, which provide support for the cell. Both plant and animal cells have a large central vacuole, which stores enzymes, nutrients, and waste for the cell.
