    Hyraxes, elephants and dugongs are more closely related to one another than to any other living animal.  Well, that's not exactly true. The closest surviving relative of the dugong is the manatee, a fresh-water, New-World version of itself. Apart from this, and the fact that there are two species of elephant and several of hyrax, it's absolutely true. Hyraxes, elephants and dugongs evolved from a single common ancestor.Hope This Helps

    This is the exact answer:

    Elephants and hyraxes share many anatomical similarities. They both have flat, hoof-like nails on the tips of their toes. They also have four toes on their front feet and three toes on their rear feet. Elephants and hyraxes both develop tusks from their incisor teeth instead of their canine teeth, like most other mammals. In addition to the anatomical similarities, fossil evidence has revealed that hyraxes and elephants share a 40-million-year-old ancestor.

    Alona [7]

    Answer:

    2 meters towards the mirror.

    Explanation:

    In a plane mirror the image distance is equal to the object distance. Therefore, by moving 2 meters towards the mirror, the boy reduces the distance between him and the mirror to two meters which is the object distance. The image distance is also 2 meters. add the two distances you will get four meters.

    A steel wire in a piano has a length of 0.600 m and a mass of 5.200 ✕ 10−3 kg. To what tension must this wire be stretched so th

    Romashka [77]

    Answer:854.39 NExplanation:

    The formula for the fundamental frequency of a stretched string is given as,

    f = 1/2L√(T/m)..................... Equation 1

    Where f = fundamental frequency, L = Length of the wire, T = Tension, m = mass per unit length.

    Given: f = 261.6 Hz, L = 0.6 m, m = (5.2×10⁻³/0.6) = 8.67×10⁻³ kg/m.

    Substitute into equation 1

    261.6 = 1/0.6√(T/8.67×10⁻³)

    Making T the subject of the equation,

    T = (261.6×0.6×2)²(8.67×10⁻³)

    T =854.39 N

    Hence the tension of the wire is 854.39 N.

    Hyraxes (from Ancient Greek: ὕραξ, romanized: , "shrewmouse"), also called dassies,[1][2] are small, thickset, herbivorous mammals in the order Hyracoidea. Hyraxes are well-furred, rotund animals with short tails. Typically, they measure between 30 and 70 cm (12 and 28 in) long and weigh between 2 and 5 kg (4 and 11 lb). They are superficially similar to pikas and marmots, but are more closely related to elephants and sea cows.

    Hyraxes have a life span from 9 to 14 years. Five extant species are recognised: the rock hyrax () and the yellow-spotted rock hyrax (), which both live on rock outcrops, including cliffs in Ethiopia[3] and isolated granite outcrops called koppies in southern Africa;[4] the western tree hyrax (), southern tree hyrax (), and eastern tree hyrax ().[5] Their distribution is limited to Africa, except for , which is also found in the Middle East.

    Characteristics[edit]

    Hyraxes retain or have redeveloped a number of primitive mammalian characteristics; in particular, they have poorly developed internal temperature regulation,[6] for which they compensate by behavioural thermoregulation, such as huddling together and basking in the sun.

    Unlike most other browsing and grazing animals, they do not use the incisors at the front of the jaw for slicing off leaves and grass; rather, they use the molar teeth at the side of the jaw. The two upper incisors are large and tusk-like, and grow continuously through life, similar to those of rodents. The four lower incisors are deeply grooved "comb teeth". A diastema occurs between the incisors and the cheek teeth. The dental formula for hyraxes is

    A hyrax showing its characteristic chewing and grunting behavior and its incisor tusks

    Although not ruminants, hyraxes have complex, multichambered stomachs that allow symbiotic bacteria to break down tough plant materials, but their overall ability to digest fibre is lower than that of the ungulates.[7] Their mandibular motions are similar to chewing cud,[8] but the hyrax is physically incapable of regurgitation[9][10] as in the even-toed ungulates and the merycism of some of the macropods. This behaviour is referred to in a passage in the Bible which describes hyraxes as "chewing the cud".[11] This chewing behaviour may be a form of agonistic behaviour when the animal feels threatened.[12]

    Hyraxes inhabit rocky terrain across sub-Saharan Africa and the Middle East. Their feet have rubbery pads with numerous sweat glands, which may help the animal maintain its grip when quickly moving up steep, rocky surfaces. Hyraxes have stumpy toes with hoof-like nails; four toes are on each front foot and three are on each back foot.[13] They also have efficient kidneys, retaining water so that they can better survive in arid environments.

    Female hyraxes give birth to up to four young after a gestation period of 7–8 months, depending on the species. The young are weaned at 1–5 months of age, and reach sexual maturity at 16–17 months.

    Hyraxes live in small family groups, with a single male that aggressively defends the territory from rivals. Where living space is abundant, the male may have sole access to multiple groups of females, each with their own range. The remaining males live solitary lives, often on the periphery of areas controlled by larger males, and mate only with younger females.[14]

    Hyraxes have highly charged myoglobin, which has been inferred to reflect an aquatic ancestry.[15]

    Similarities with Proboscidea and Sirenia[edit]

    Hyraxes share several unusual characteristics with mammalian orders Proboscidea (elephants and their extinct relatives) and Sirenia (manatees and dugongs), which have resulted in their all being placed in the taxon Paenungulata. Male hyraxes lack a scrotum and their testicles remain tucked up in their abdominal cavity next to the kidneys,[16][17] as do those of elephants, manatees, and dugongs.[18] Female hyraxes have a pair of teats near their armpits (axilla), as well as four teats in their groin (inguinal area); elephants have a pair of teats near their axillae, and dugongs and manatees have a pair of teats, one located close to each of the front flippers.[19][20] The tusks of hyraxes develop from the incisor teeth as do the tusks of elephants; most mammalian tusks develop from the canines. Hyraxes, like elephants, have flattened nails on the tips of their digits, rather than the curved, elongated claws usually seen on mammals.[21]

They also have four toes on their front feet and three toes on their rear feet. Elephants and hyraxes both develop tusks from their incisor teeth instead of their canine teeth, like most other mammals.

    Answer from: UngJae0213

    SHOW ANSWER

    Although elephants and hyraxes at first don't seem to have many similarities, a closer look has led many scientists to believe that these animals are evolutionarily closely related.

    Elephants and Hyraxes share many reproductive characteristics that indicate a common ancestor: The location of the testicules in these animals diverges from most mammalian species, remaining inside the retroperitoneal abdomen. Females have similar placental origins and long gestation periods and the location of the mammary glands in both orders (above the front legs) is a unique feature among non-primate mammals. Hyraxes' tusks develop from incisor teeth, similar to elephants, and in both cases nails develop into flattened, hoof-like structures.

    Molecular evidence has also been used to confirm the hypothesis of evolutionary relatedness between the two orders, as similarities in some gene sequences in mitochondrial DNA and other molecular components. Both animals have some physiological similarities and cognitive characteristics (such as the presence of a powerful long-term memory) that support the possibility of evolutionary proximity.

    The fossil record indicates that in the Eocene period hyraxes were dominant herbivores in Africa, with several species, reaching much larger sizes than today and occupying different ecological niches, indicating that elephants and hyraxes may have been very similar millions of years ago.
