Explanation: During cell division, chromatin condenses to form chromosomes.
The total productive areas in which a population, a person, or a product competes are tallied as ecological footprint. It gauges the ecological resources needed by a particular population or product to produce the natural resources it consumes (such as plant-based food and fiber products, livestock and fish products, timber and other forest products, and space for urban infrastructure), as well as to absorb its waste, particularly carbon emissions.
<h3>What is ecological reserve/deficit?</h3>
An ecological deficit happens when a population's ecological footprint exceeds the biocapacity of the space that population has access to. If a country has a national ecological deficit, it is either importing biocapacity through commerce, selling off its ecological resources, or releasing carbon dioxide waste into the sky. When a region's biocapacity surpasses its population's ecological footprint, an ecological reserve is created.
