Explanation:
1. An ecosystem is MOST likely to return to its original condition after Tall prairie grass burns after being struck by lightning.
Here is a research paper in which they explained how this happened. (Komarek, E. V. (1971). Lightning and fire ecology in Africa. In Tall Timbers Fire Ecology Conference (Vol. 11, pp. 473-509).)
2. In some national parks, controlled fires are maintained by firefighters. The major reasons for using controlled burns to maintain certain ecosystems is to give nonnative plants a chance to colonize the region.
A recent article provided the insight of this situation (Xanthopoulos, G., Delogu, G. M., Leone, V., Correia, F. J., & Magalhães, C. G. (2020). Firefighting approaches and extreme wildfires. In Extreme Wildfire Events and Disasters (pp. 117-132). Elsevier.)
3. One reason for the change in the Galápagos ecosystem has been the introduction of species that were not on the island before, such as donkeys, goats, cats, dogs, and insects. The introduction of nonnative species MOST likely disrupt the balance of life on the islands due to greater competition for limited food sources.
Scientist said that food competition is actually a struggle to survive in any ecosystem here is the reference paper (Eckhardt, R. C. (1972). Introduced plants and animals in the Galapagos Islands. Bioscience, 22(10), 585-590.)
46 Cromosomas
Las células del ser humano tienen 23 pares de cromosomas, 22 pares de autosomas y un par de cromosomas sexuales. Por tanto, cada individuo tiene 46 cromosomas en sus células. Por lo tanto, el número de cromosomas presentes en una célula nerviosa de un ser humano es de 46 cromosomas.
A former meadow is turned into a housing complex, and the next year, fewer milkweed blooms are seen due to pollination.
What applications does milkweed have?
The herb has also been used medicinally despite the danger of poisoning. Many native cultures chewed the roots of milkweed to heal diarrhea and used the sap to remove warts. Infusions and salves were also made from it to treat asthma, coughing, fevers, rashes, and swelling.
What kind of soil is ideal for milkweed growth?
In regions with more rainfall, like the eastern United States, milkweed thrives. Asclepias tuberosa, sometimes known as butterfly weed, thrives in drier climates like those in the western United States. Sand or gravelly soils are required. The Clay variety is an anomaly since it thrives on heavier soils, especially dry clay. Plant under the intense sun.

Answer:
The difference is due to the succeeding vowel sound strength (whether it is weak or strong)
Explanation:
"ch" produces "k" like sound. Whenever , alphabet "c" with in any word comes before any weak vowel sound such as i or e , it always sound as "ch".
Therefore, c and ch in gioco and giochi are sound similar.
"sc" sounds like "sh" when it comes before any weak vowel sound (as in the case of capisci)
"sc" sounds like "sk" when it comes before any strong vowel sound (as in the case of capisco)
