Complete proteins are food sources that consists of the nine essential amino acids. The body cannot synthesize essential amino acids on its own, and therefore, require external sources of them.Learn more at: https://brainly.com/question/24231901?referrer=searchResults
The Tasmanian devil (Sarcophilus harrisii) is a species of mammal whose only wild population is native to the isolated island of Tasmania, off the coast of Australia. Tasmanian devils have a very low level of genetic diversity across the entire species. Researchers hypothesize this lack of diversity is the result of several genetic bottlenecks in the species’ history. In 1996 a new disease called devil facial tumor disease (DFTDDFTD) appeared in the wild Tasmanian devil population. DFTDDFTD can spread from one animal to another and causes the death of most affected animals. The impact of DFTDDFTD on the Tasmanian devil population has resulted in a decrease in the total population of more than 85% over the last two decades. (a) Describe the process that maintained a stable Tasmanian devil population size before the appearance of DFTDDFTD in 1996. (b) Explain how the huge reduction of the Tasmanian devil population since 1996 affects the susceptibility of the current population to new diseases in comparison with the susceptibility of the population before 1996. (c) Tasmanian devils are top predators and are considered a keystone species in their community. Predict the effect of the rapid reduction of the Tasmanian devil population on the rest of the community. (d) Justify the prediction of Part c
The Tasmanian devil (Sarcophilus harrisii) is a carnivorous marsupial of the family Dasyuridae. Until recently, it was only found on the island state of Tasmania, but it has now been reintroduced to New South Wales in mainland Australia, with a small breeding population.[3] The size of a small dog, the Tasmanian devil became the largest carnivorous marsupial in the world, following the extinction of the thylacine in 1936. It is related to quolls, and distantly related to the thylacine. It is characterised by its stocky and muscular build, black fur, pungent odour, extremely loud and disturbing screech, keen sense of smell, and ferocity when feeding. The Tasmanian devil's large head and neck allow it to generate among the strongest bites per unit body mass of any extant predatory land mammal. It hunts prey and scavenges on carrion.
Although devils are usually solitary, they sometimes eat and defecate together in a communal location. Unlike most other dasyurids, the devil thermoregulates effectively, and is active during the middle of the day without overheating. Despite its rotund appearance, it is capable of surprising speed and endurance, and can climb trees and swim across rivers. Devils are not monogamous. Males fight one another for females, and guard their partners to prevent female infidelity. Females can ovulate three times in as many weeks during the mating season, and 80% of two-year-old females are seen to be pregnant during the annual mating season.
Females average four breeding seasons in their life, and give birth to 20 to 30 live young after three weeks' gestation. The newborn are pink, lack fur, have indistinct facial features, and weigh around 0.20 g (0.0071 oz) at birth. As there are only four nipples in the pouch, competition is fierce, and few newborns survive. The young grow rapidly, and are ejected from the pouch after around 100 days, weighing roughly 200 g (7.1 oz). The young become independent after around nine months.
It is believed that ancient marsupials migrated across Gondwana tens of millions of years ago, and that they evolved as Australia became more arid. Fossils of species similar to modern devils have been found, but it is not known whether devils are descended from these species or co-existed with them. It is unclear when Tasmanian devils became locally extinct from the Australian mainland; most evidence suggests they had contracted to three relict populations around 3000 years ago. A tooth found in Augusta, Western Australia, has been dated to 430 years ago, but archaeologist Oliver Brown disputes this and considers the devil's mainland extinction to have occurred around 3000 years ago.[4] This disappearance is blamed on climate change, a population increase in humans and the introduction of the dingo, the latter of which is absent from Tasmania.[5][6]
In 1941, devils became officially protected, and since then, scientists have contended that earlier concerns over the threat to livestock were overestimated and misplaced. Since the late 1990s, the devil facial tumour disease (DFTD) has drastically reduced the population and now threatens the survival of the species, which in 2008 was declared to be endangered. Programs undertaken by the Government of Tasmania to reduce the impact of the disease include an initiative to build up a group of healthy devils in captivity, isolated from the disease. Localised populations of devils have also been severely reduced by collisions with motor vehicles, particularly when they are eating roadkill.
The devil is an iconic symbol of Tasmania and many organisations, groups and products associated with the state use the animal in their logos. It is seen as an important attractor of tourists to Tasmania and has come to worldwide attention through the Looney Tunes character of the same name. Starting in 2013, Tasmanian devils are again being sent to zoos around the world as part of the Australian government's Save the Tasmanian Devil Program.
The process that maintained a stable size of the tasmanian devil in the population before the appearance of DFTDDFTD in 1996 was to have no diseases that decimated the population with no possibility of cure the huge reduction in the population of tasmanian devils, resulting in problems on the food web. To find out more.......
Answering step by step(A) the process that maintained a stable population size of Tasmanian devils prior to the appearance of DFTDDFTD in 1996. Was to have no specialized diseases, transmitted from individual to individual in the population of these animals. (B) the enormous reduction in the population of Tasmanian devils since 1996 has been affecting the susceptibility of the current population to new diseases compared to the susceptibility of the population before 1996, by the emergence of an uncontrollable and transmissible disease, this disease has decimated the populations of this animal, without cure and apparent control. (C)and (D) Tasmanian devils are top predators and are considered a key species in their community. With this, it is predicted that the rapid reduction of the population of Tasmanian devils will bring an imbalance in this community, as the number of animals that are below their trophic level will prevail in the rest of the community.Tasmanian Devil Facial TumorTasmanian Devil Facial Tumor or Tasmanian Devil Facial Cancer (TFDT is an
Aggressive Non-viral Transmissible neoplasm (cancer)That affects Tasmanian devils. The first official record has been made in Tasmania in 1996. Over the years, the disease has devastated wild devil populations, with an estimated decline of 20% to 50% in approximately 65% of the island. Newly decided populations up to 10% 12 to 18 years of age. The major pathology in the eastern half of Tasmania. Signs of TFDT begin as ease and strain around the mouth. These develop into cancerous tumors that spread to the entire face and face. eventually, by the body. Tumors interfere with feeding, leading the animal to death by starvation. The facial tumor originates from Schwann cells.
With this information, we can conclude that Tasmanian Devil Facial Tumor is causing a great impact on the Tasmanian devil population, and that in this case human intervention is necessary to perpetuate the species and to maintain the balance in the habitat ecology and food web.

What's the main reason why cell specialization is important?
Question 12 options:
It allows multicellular organisms to perform many distinct functions.
It allows unicellular organisms to perform many distinct functions.
It generates totipotent cells.
It creates cells at a faster rate.
Answer:
It allows multicellular organisms to perform many distinct functions.
Explanation:
Cell specialization is important primarily because it allows multicellular organisms to perform many distinct functions. Cell specialization isn’t important in unicellular organisms, because it doesn’t occur. Cell specialization isn’t important primarily for creating cells faster, and it doesn’t generate totipotent cells. Rather, totipotent cells are the stem cell progenitors that allow cell specialization to occur.
It makes it possible for multicellular creatures to carry out a wide variety of unique roles. Therefore, option (A) is correct.
What is cell specialization?The transformation of a stem cell into a differentiated cell type is accomplished by a process known as cellular differentiation. Typically, the cell will transform into a type that is more specialized.
The primary reason why cellular specialization is so important is that it enables multicellular organisms to carry out a wide variety of diverse jobs. Because it does not take place in unicellular creatures, the process of cell specialization is irrelevant to their biology. The primary reason why cell specialization is not crucial is that it does not produce totipotent cells, nor does it speed up the process of making new cells. Instead, totipotent cells are the progenitors of stem cells, which are the cells that can differentiate into specialized cell types.
