The better answer is organism
In eukaryotic cells cellular structure is composed of a neatly packaged DNA molecule histone octamer.
In eukaryotes, however, genetic material is housed inside the nucleus and tightly packaged into linear chromosomes. Chromosomes are made of a DNA protein complex called chromatin this is prepared into subunits referred to as nucleosomes. A chromosome is made up of proteins and DNA organized into genes. each cell usually incorporates 23 pairs of chromosomes.
The records in DNA is stored as a code made from four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Human DNA includes about bases, and greater than 99 percentage of those bases are the identical in every person.
DNA is tightly packed up to healthy inside the nucleus of each cell. As proven within the animation, a DNA molecule wraps round histone proteins to shape tight loops known as nucleosomes. these nucleosomes coil and stack collectively to shape fibers referred to as chromatin.

The right answer is climate change.
Amphibians do not have the possibility of producing heat. Their activity depends on the environmental temperature and its fluctuations. For example, an average temperature increase of 1 ° C is likely to increase the metabolic expenditure of ectotherms by at least 10 to 30%. Global warming has or will have a significant impact on populations and their ability to adapt according to the evolutionary history of species.
