DNA and RNA are the genetic code. They are passed form the ancestor to offspring. They code for a mix of traits from the parents and tell the cells what to do what traits to form, and overall how to function
As succession proceeds in an ecosystem, there is an increase in population density. This is accompanied by the change in the species diversity as well. Thus, the correct option is B.
Ecological succession is the process through which the mixture of species and habitat in an area changes over the period of time. Gradually, these communities of species replace one another until a climax community like a mature forest is reached in that ecosystem, or until a disturbance, like a fire, occurs in that region.
The succession of an ecosystem begins with a pioneer species such as the lichens, some fungi species. Species such as the lichen begins to secrete acids which begin to break the barren land into a number of small particles. The small particles mix with the lichen species remains and starts the process of soil formation. On addition of the soil, more diverse plant species such as bryophytes and pteridophytes grow on the land. Later on, these plants are replaced by the most diverse angiosperm species. In this way, the species diversity tends to increase as a result of ecological succession.
Therefore, the correct option is B.

Answer: B.
Explanation: Ecological succession, quite literally, is the change in the species of an area/ecosystem that had earlier been completely wiped out. Wildfires are a prime example of that.
Answer:
B is the closest.
Explanation:
Its a direct and obvious lean toward lake and forest
Answer:
B lake for animal and bird for forest.
Cells that have no mitochondria are unable to convert oxygen into energy, found in the form of adenosine triphosphate (ATP). All multicellular eukaryotic organisms, including plants and animals, have mitochondria in some cells, but prokaryotes and some single-cell eukaryotes do not have mitochondria.
If a cell can't produce energy, it would be unable to perform vital processes, leading to its death. On an organism level, inability to produce energy in a significant number of cells can lead to system failures and potentially, premature death.
If a cell cannot produce energy, over time, it would not be able to carry out critical functions such as growth, repair, transportation of nutrients, and reproduction. This condition could lead to the cell's eventual death. In an organism, if a sufficient number of cells are unable to produce energy, it could lead to system failures and ultimately, premature death of the organism. This is because the working of an organism depends on the collective effort of its cells which require energy to function.
