Option C is the right choice. Since the start of industrialization in the 1800s, the concentration of carbon dioxide in the atmosphere has risen <span>. This increase is attributed to emissions from industrial machinery and vehicles.

The variations caused by genetic modification lead to alterations in the organism's genome. Such changes express traits in ways that differ from the typical. These variations can cause genetic mutations that may be passed down generations.
In the case of sexual reproduction, the organism's genome remains unchanged. Here, only an exchange occurs between the alleles inherited from each parent, and this does not result in mutations.
A gene is a segment of DNA that typically contains the code for a particular protein influencing a specific trait, while an allele is a segment (a version) of that gene. The correct choice among the options is option "D".
It explains that in a closed system, for a specific mass of an ideal gas at a steady pressure, its volume is directly proportional to its absolute temperature.
