Answer:
Explanation:ll scars tell a story. A childhood fall, an adult fight, an accident, an assault—all will leave their mark. In modern times, the elective scar of a surgical incision has gone from the large heroic scars (the bigger the better) of general surgery, to the carefully planned, minimally invasive incisions of modern times. Once the sign of a great surgeon, the prestigious elective scar is now the nearly invisible scar. The contributions of war-related medical advances represent an important chapter in medical history. Survival from the complex blast/burn/bullet injuries of modern weapons is nearly assured and provides new challenges for recovery. Thus, the history of scars, from ancient wounds to the horrendous scars that signify survival from grievous injury, tells the story of not only human resilience, but of medical miracles.
Scars result from healing without regeneration through the deposition of collagen and fibrous connective tissue. Why the salamander can regenerate a leg and other tissue, but a human cannot, is an evolutionary conundrum. A common laboratory regeneration model is the Mexican axolotl (Fig. 1-1). This endangered species regenerates entire limbs as well as nervous tissue. Mammals are known for some specific regenerative capacities, like antlers in the deer family, which are shed and regrown annually. Humans may be able to regenerate the endometrium, liver, and kidney, but only minimal segments of fingers or toes. In general, humans heal after injury by the formation of scar tissue as a means of bridging the defect, whether it involves only skin or larger chunks of skin muscle and bone.
What is the evolutionary advantage of healing by scar versus regeneration? Energy requirements for wound healing in humans are well documented. For a simple femur fracture, the bedridden patient who normally requires 2,500 calories per day may require up to 6,000 calories per day.1 Burns, in particular, result in high caloric requirements during recovery and are significant scar-forming injuries.2 Burns involving less than 20% of the total body surface and wartime amputations were frequently fatal until nearly the end of the 19th century, and only slightly larger burns until well after 1950. The relative efficiency in time and energy requirements for scar healing compared to regeneration after major injury is likely an evolutionary advantage for the species, if not for the modern individual.
As the complex biology of wound healing becomes increasingly understood, greater insights into the modulation of healing and vertebrate regeneration are emerging. Genetic manipulation in one mouse species has even restored regenerative capacity. The Lin28a gene, silenced in maturing vertebrates, restores regenerative ability when turned on in mouse infancy, but not in maturity.3 Another species, the African spiny mouse, can heal full-thickness skin injuries without scarring. Current intensive research on the use of stem cells for regeneration is widespread, as are clinical practices promoting their use, despite limited documentation in controlled clinical trials. The identification of the Lin28a and b genes and their role in stem cell regeneration is also being rapidly elucidated.4 These concepts offer the promise of future transformative approaches to healing human tissues.
Scars are destined to become part of medical lore if the full potential of current research on genetic manipulation, embryonic healing, and stem cell applications is achieved. The management of scars to date has depended on the prevention of injury, the optimization of wound healing, and the direct treatment of scars after they have formed. This chapter will explore the progress in scar care through history, as well as the meaning scars have had in medicine, law, and literature. So many different individuals have contributed to our knowledge of wounds, their management, and the diagnosis and treatment of scars that not all of them can be introduced in this chapter. Table 1-1 provides an outline of the more important events in the years preceding the modern era of wound care and scar management. I have chosen not to focus on events of this modern era. Rather, I have offered my own view of some of the key people and events prior to the last 60 years. More recent advances are the province of other authors in their respective chapters.

a flower is ready to become a fruit. where would the instructions be found
Answer is A. Nucleus.
Flower is the reproductive organ of a flowering plant that contains male reproductive organ ( stamen) and female reproductive organ (carpel). Anther of the stamen produces male gamete and within the ovary of the carpel produced female gamete. After fertilization male gamete and female gamete fuses to form zygote. Zygote is a single cell whose nucleus has chromosomes, where all the genetic information regarding development of fruit and seed are stored.

trial by jury
an experienced lawyer
a panel of justices
Answer:
Trial by jury
Explanation:
This is something huge in our constitution and you are guaranteed to have jury.
Trial by jury is guaranteed by the constitution during criminal cases.
What is trial by jury?A jury refers to a group of people who are law abiding in a community; who have been assigned to pronounce an impartial decision on a legal issue.
Here, it is the duty of the jury to make a decision on any criminal case, however, the final application of the decision is done by the judge. It is therefore different from a bench trial where a judge or panel of judges makes all decisions.
Hence, trial by jury is guaranteed by the constitution during criminal cases.

When he came to power in 1985, Soviet leader Mikhail Gorbachev
A. was seen as unlikable and opposed to change.
B. refused to meet with President Reagan.
C. hoped to improve relations with the West.
D. threatened aggressive military action against the United States.
Answer:
The foreign policy of the Ronald Reagan administration was the foreign policy of the United States from 1981 to 1989. The main goal was winning the Cold War and the rollback of Communism—which was achieved in the Revolutions of 1989 in Eastern Europe during 1989 and in the Dissolution of the Soviet Union in 1991. Historians debate whom to credit, and how much. They agree that victory in the Cold War made the U.S. the world's only superpower, one with good relations with former Communist regimes in Russia and Eastern Europe
When he came to power in 1985, Soviet leader Mikhail Gorbachev: hoped to improve relations with the West. The correct option is C.
When Mikhail Gorbachev became General Secretary he took several reforms that aimed at addressing the Soviet Union's problems. Gorbachev aspired to improve relations with the West as part of these changes.
Through political transparency, Mikhail Gorbachev's programmes attempted to reinvigorate the Soviet economy and minimise disputes between the East and the West. Gorbachev attempted to normalise relations with the West in order to alleviate Cold War tensions.
Thus, the ideal selection is option C.

Why did it take so long for the Renaissance to take root in England?
Answer:
Explanation:
Peasants working on feudal lands in England in 1310. ... Feudalism was much more present in European society outside of Italy which caused the ideas of the Renaissance to spread slowly. This was because Feudal society was not as open to new ideas as the city-states that existed in Italy at the time. I think.
Which battle do you think was most important in establishing the eventual victory of the colonies over Britain?
answer in full sentences (100 points!!!)
The war was fought primarily along the frontiers separating New France from the British colonies from Virginia to Nova Scotia. The Ohio Country (sometimes called the Ohio Territory or Ohio Valley by the French) was the name used in the 18th century for the regions of North America west of the Appalachian Mountains and in the region of the upper Ohio River south of Lake Erie. The territory encompassed roughly the present-day states of Ohio, eastern Indiana, western Pennsylvania, and northwestern West Virginia. The issue of settlement in the region is considered to have been a primary cause of the French and Indian War and a later contributing factor to the American Revolutionary War.
