What pigment traps the energy?
Vadim26 [7]
The pigment that traps energy is Chlorophyll. Chlorophyll is a green pigment commonly found in almost all plants, algae and cynobacteria. Leaves appear green because they contain this pigment. This pigment absorbs the light energy from the sun to complete the process of photosynthesis or food production of plants. Chlorophyll is said to absorb light in the long wavelength and blue in the short wavelength regions of the visible light spectrum. Green light is not absorbed, thus making the leaves of some plants green. Chlorophyll is found at the plant’s chloroplasts, which comes to have different structures.

Answer:

Explanation:

Australopithecina or Hominina is a subtribe in the tribe Hominini. The members of the subtribe are generally Australopithecus (cladistically including the genera Homo, Paranthropus,[2] and Kenyanthropus), and it typically includes the earlier Ardipithecus, Orrorin, Sahelanthropus, and Graecopithecus. All these related species are now sometimes collectively termed australopithecines or homininians.[3][4] They are the extinct, close relatives of humans and, with the extant genus Homo, comprise the human clade. Members of the human clade, i.e. the Hominini after the split from the chimpanzees, are now called Hominina[5] (see Hominidae; terms "hominids" and hominins).

While none of the groups normally directly assigned to this group survived, the australopithecines do not appear to be literally extinct (in the sense of having no living descendants) as the genera Kenyanthropus, Paranthropus and Homo probably emerged as sister of a late Australopithecus species such as A. africanus and/or A. sediba.

The terms australopithecine, et al., come from a former classification as members of a distinct subfamily, the Australopithecinae.[6] Members of Australopithecus are sometimes referred to as the "gracile australopithecines", while Paranthropus are called the "robust australopithecines".[7][8]

The australopithecines occurred in the Plio-Pleistocene era and were bipedal, and they were dentally similar to humans, but with a brain size not much larger than that of modern apes, with lesser encephalization than in the genus Homo.[9] Humans (genus Homo) may have descended from australopithecine ancestors and the genera Ardipithecus, Orrorin, Sahelanthropus, and Graecopithecus are the possible ancestors of the australopithecines.[8]

as the submersible approaches the twilight zone (300m deep), what changes in light and temperature occur?
Sunny_sXe [5.5K]

In the twilight zone, the temperature and the light conditions change. The initial 200 meters of the ocean as considered as the open ocean. There is availability of light and thriving temperature there. Butt below that, in the 'deep ocean'. The availability of light decreases and as we go further down, the light no longer reaches those parts of the ocean. Moreover, the temperatures plummet down to almost freezing conditions. In addition to this, the pressure is much more higher in the deep ocean.
