Each organism has some degree of homeostasis, i.e., it is able to make adjustments so that its internal environment remains relatively constant despite changes in the external environment.

The correct Answer is:
### Step-by-Step Solution: 1. **Understanding Homeostasis**: - Homeostasis refers to the ability of an organism to maintain a stable internal environment despite external changes. This is crucial for sustaining life. 2. **Dynamic Process**: - Homeostasis is not a static condition; it is a dynamic process. Organisms continuously adjust their internal systems to respond to fluctuations in their external environment. 3. **Role of the Endocrine and Nervous Systems**: - In humans, the endocrine system (hormonal responses) and the nervous system (neural responses) play vital roles in detecting changes in both internal and external environments. They act as sensors and regulators. 4. **Feedback Mechanisms**: - Organ systems utilize feedback mechanisms to maintain homeostasis. These mechanisms can be negative (counteracting changes) or positive (enhancing changes) to stabilize the internal environment. 5. **Examples of Homeostasis**: - Examples include temperature regulation (sweating or shivering), blood sugar levels (insulin and glucagon), and fluid balance (thirst response).

  • buyer's Remorse: the european union and the grexit ernest hemingway once boasted that he could tell a story in six words: "for sale: baby shoes, never worn. " Nonetheless, I'm not impressed, ask me to summarize something as vast as the global whole of the 20th century, and I think i can do him four better: europe fought. 100 years, eight popes, and two world wars all boiled down to just those words. Europe. fought. such a volatile connected history makes it all the more fascinating that the entirety of the combative continent was able to redress its respective grievances, apply the salve to decades-old festering wounds, shuck off fervent nationalism, and join together in marital bliss as a veritable european union. but the honeymoon--as honeymoons are wont to do--has ended. the initial endorphin rush of uniting toward a greater purpose has long passed, and all of europe now finds itself in something very much like international relationship counseling. " he can't manage our finances, " Germany bemoans as the reluctant breadwinner. "she refuses to help now that i need her most,"Germany bemoans as the reluctant breadwinner. "she refuses to help now that i need her most, "greece exclaims. "listen to you tow! you have no iddea of the sordid sort of things that we've seen!" the rest of the continent marvels, obliged to play a role somewhere between character witness and neutral arbiter in this geopolitical lovers' quarrel. yet, as the saying goes, "breadking up is hard to do. " now that all low-hanging fruit romantic metaphors have been exhausted, at that crossroads is where we now find ourselves. tomorrow, Greece will go before its creditors to learn its fate: either the rest of europe (read: and chancellor angela merkel) will extend a £ 1.5 Billion loan to the greeks so that they might pay off a previous international monetary fund float, or this idyllic mediterranean titan of yore will finally meet its end, defaulting on its debt and hopping the next train toward the ghost town called european banishment. such an exit (dubbed Grexit by the media, In their eminent wit) might well be the first domino to fall in a series of developments that could destabilize the region and threaten the validity and vitality of the E.U henceforth. consequential possibilities abound. for one, should greece receive said funding and be permitted to remain, at what point does Germany tire of paying child support? the natural conclusion to that fatigue in berlin would be a harried rummaging through the attic in search of leftover deutsche marks, desperate to replace the Euro and nostalgic for the autonomy of yesteryear when currency was their own and not some perverted fiscal tragedy of the commons. Moreover, the precedent is set for further disqualification with a Grexit, perhaps spain, portugal, lreland, or italy might be the next one left without a chair when the music stops, resigned to their fate as wallflowers on the outside looking in. yet, perhaps the most troublesome possibility is that an isolated greece would be an impressionable Greece disperate both for allies and access to their coffers. Current Greek optimistic sentiment is that russia might don its shining armor and rescue the fledgling castaways with a godsend of a loan. But, give putin's recent sleight of handin crimea, any such lending may not be so much an act of charity as a trojan horse, valdimir's kremlin friends are a crafty bunch, and their endgame is opaque. Alas, such is the problem with deciphering ulterior motives: they often aren't clear until the history books go to print. The trillion dollar question is, when the ink dries, will the EU. be listed in the chapters of current events? Or, will it be relegated to the annals of academia, its skeleton but a diplomatic case study of oil and water, its ashes little more than a kennedy school lecture on the perils of collaboration between square pegs and round holes? what is the overall point of the passage?

    A
    to explain the current challenges of the european union and ponder its future
    B
    to make the case that greece should have never been admitted to the european union
    C
    to convince the reader that a continent-wide currency is a rejection of sound economic theory
    D
    to demonstrate how russia is often helpful to floundering countries

    Read the following statements and select the correct ones. i) All vertebrates are capable of osmoregulation and thermoregulation. ii) Some species have evolved the ability to regulate, but only over a limited range of environmental conditions, beyond which they simply conform. iii)99 per cent of animals and nearly all plants can- not maintain a constant internal environment. - iv)Animals arc either perfect regulators or perfect conformers.

    What is so special about tropics that might account for their greater biological diversity? a. Unlike temperate regions subjected to frequent glaciations in the past, tropical latitudes have remained relatively undisturbed for millions of years and thus, had a long evolutionary time for species diversification. b. Temperate environments, unlike tropical ones, are less seasonal, relatively more constant and predictable. Such constant environments promote niche specialization and lead to a greater species diversity. c. There is more solar energy available in the tropics, which contributes to higher productivity, this in turn might contribute indirectly to greater diversity.

    A botanist is cultivating a rare species of plant in a controlled environment and currently has 3000 of these plants. The population of this species that the botanist expects to grow next year, N_("next year") , can be estimated from the number of plants this year, N_("this year") , by the equation below. N_("next year")=N_("this year")+0.2(N_("this year"))(1-(N_("this year"))/(K)) The constant K in this formula is the number of plants the environment is able to support. The botanist would like to increase the number of plants that the environment can support so that the population of the species will increase more rapidly. If the botanist’s goal is that the number of plants will increase from 3000 this year to 3360 next year, how many plants must the modified environment support?
