Answer:
Everything living would die
Answer:
Without DNA, cells could not reproduce, which would mean extinction of the species. Normally, the nucleus makes copies of chromosomal DNA, then segments of DNA recombine, and next the chromosomes divide twice, forming four haploid egg or sperm cells.

Answer:
a. aquatic insects
Explanation:
Aquatic insects constitute an important component of freshwater aquatic biodiversity. In addition to being very abundant in rivers and streams, they are also present in lakes and temporary water stagnations (wetlands). In water sources, these insects can live attached to stones, in decaying leaves and plant material or buried in fine sediment. Aquatic insects have different eating habits and therefore have multiple behavioral and morphological modifications.
Aquatic insects can live attached to stones, in decaying leaves and plant material or buried in fine sediment. According to the place where they live and the availability of resources, these insects have different eating habits. In this line, we have predatory aquatic insects of other insects or vertebrates such as turtles (access contents about turtles) and fish, feeding on living tissue of vascular plants and detritivorous habits that means that they feed on organic matter in suspension in the water column.
In the evolutionary history of aquatic insects, due to diversification in eating habits, they have modifications in their body appendages. In this context, we have predatory aquatic insects with raptorial legs to hold the prey, with a raptorial lip like dragonflies for the same purposes, and other detritus filters have multiple mushrooms on the anterior legs and mouth structures to retain organic matter.
According to the mode of acquisition of food, we have predators that actively forage in search of prey such as dragonflies, also passive predators such as hemiptera of the Belostomatidae family. Detritivorous aquatic insects, meanwhile, can be filters, crushers, collectors or scrapers of organic matter.
The sphincter pupillae muscle controls decreasing pupil size in response to brighter light levels. This action protects the eye from potential damage. The process is involuntary and controlled by the autonomic nervous system.
The pupil size in our eyes is controlled by two muscles: the sphincter pupillae and the dilator pupillae. When we are exposed to brighter light levels, the sphincter pupillae muscle contracts, which causes the pupil to decrease in size. This acts as a protective mechanism to prevent too much light from entering the eye and possibly causing damage.
The functioning of these muscles are involuntary and controlled by the autonomic nervous system. In contrast, in lower light levels, the dilator pupillae muscle would contract to increase pupil size and allow more light in for improved vision.

The water bodies affects the climate of the particular place because it influences the air pressure near the water bodies.
The heated air takes much energy to heat the water bodies so the environment there is moderate.
In case when the air is cooler than water then heat goes from water to air and it does not takes much energy to raise the temperature of the air.
In this way the climate is moderate at the coastal regions.
