The Saharan silver ant (*Cataglyphis bombycina*) foraging in the desert heat relies on unique triangular-shaped hairs to stay cool. Researchers found that these hairs have a triangular cross-section that reflects both visible and near-infrared light while facilitating heat dissipation in the mid-infrared spectrum. This dual optical effect allows the ants to maintain a body temperature below their critical thermal maximum of , even when the desert sand reaches temperatures as high as . Unlike other insects that seek shade during peak midday hours, *Cataglyphis bombycina* actively searches for food during this period to avoid predators.
According to the text, which statement is true about the triangular-shaped hairs of the Saharan silver ant?
- AThey protect the ants from predators that are active during peak midday hours.
- They reflect visible and near-infrared light and assist in dispersing heat in the mid-infrared spectrum.Cevap
- CThey allow the ants to survive body temperatures that exceed .
- DThey help the ants locate food sources that are hidden in shaded areas of the desert.
Cevap
The correct answer states that the hairs reflect visible and near-infrared light and assist in dispersing heat in the mid-infrared spectrum.
The passage explicitly describes the optical properties of the triangular-shaped hairs, stating that they reflect both visible and near-infrared light and facilitate heat dissipation in the mid-infrared spectrum. The correct option directly paraphrases these details.
