Triplet oxygen, 3 O 2, refers to the S = 1 electronic ground state of molecular oxygen (dioxygen). Molecules of triplet oxygen contain two unpaired electrons, making triplet oxygen an unusual example of a stable and commonly encountered diradical : [ 2 ] it is more stable as a triplet than a singlet .
Cataglyphis [2] is a genus of ant, desert ants, in the subfamily Formicinae.Its most famous species is C. bicolor, the Sahara Desert ant, which runs on hot sand to find insects that died of heat exhaustion, and can, like other several other Cataglyphis species, sustain body temperatures up to 50°C.

The species is common and widely distributed in eastern United States, where they tend to inhabit forested areas. The ground-dwelling ants build their nests in plant cavities, in the soil or under rocks. [2] It is sometimes called the acorn ant because it can live inside hollowed out acorns. [3] [4] Acorn ants are found in both rural and urban ...
Ants are active all year long in the tropics; however, in cooler regions, they survive the winter in a state of dormancy known as hibernation. The forms of inactivity are varied and some temperate species have larvae going into the inactive state ( diapause ), while in others, the adults alone pass the winter in a state of reduced activity.
During the closed phase of discontinuous gas exchange cycles, the spiracle muscles contract, causing the spiracles to shut tight. At the initiation of the closed phase, the partial pressure of both O 2 and CO 2 is close to that of the external environment, but closure of the spiracles drastically reduces the capacity for the exchange of gases with the external environment.

An electron configuration with two unpaired electrons, as is found in dioxygen orbitals (see the filled π* orbitals in the diagram) that are of equal energy—i.e., degenerate—is a configuration termed a spin triplet state. Hence, the ground state of the O 2 molecule is referred to as triplet oxygen.
This week is going to be a scorcher — with 100-plus temperatures in the forecast all week. We asked a professional exterminator if they’d gotten more calls about wayward insects because of the ...
Plerergates can live anywhere in the nest, but in the wild, they are found deep underground, unable to move, swollen to the size of grapes. [7] In Camponotus inflatus in Australia, repletes formed 49% (516 ants) of a colony of 1063 ants, and 46% (1835 ants) of a colony of 4019 ants. The smaller colony contained six wingless queens.
