John is 70 years old. He has been a chain smoker throughout his adult years. Consequently, he is now unable to clearly see objects that are in close proximity, even though he has relatively normal peripheral vision. The disease that has marred John's vision is macular degeneration.

Blurred vision is a key symptom. It's typically due to abnormal blood vessels that leak fluid or blood into the macula. The macula is the part of the retina liable for significant vision. Blurred vision is a key symptom. A special combination of vitamins and minerals may lessen disorder progression. the surgical procedure will also be a choice.

Age-related macular degeneration (AMD) is an eye disorder that could blur your principal vision. It happens while growing old and causes damage to the macula — the part of the eye that controls sharp, directly-ahead vision. The macula is a part of the retina (the light-sensitive tissue at the back of the eye).

Macular degeneration causes loss within the center of the sector of imagination and prescient. In dry macular degeneration, the center of the retina deteriorates. With moist macular degeneration, leaky blood vessels develop beneath the retina.

Ecological succession refers to the process of changing in an ecological community's species composition through time. The time frame might span several decades or fewer (for instance, following a wildfire).

The community grows through an increase in complexity from a small number of pioneer plants and animals to a stable or self-sustaining climax community. The effects of established species on their own settings serve as the "engine" of succession and the reason why ecosystems evolve. Living has the effect of changing one's surroundings, sometimes subtly and sometimes blatantly.

Simon bolivar had a major effect on Caribbean South American history by:
4vir4ik [10]

Answer:

The history of Cuba is characterized by dependence on outside powers—Spain, the US, and the USSR. The island of Cuba was inhabited by various Amerindian cultures prior to the arrival of the Genoese explorer Christopher Columbus in 1492. After his arrival on a Spanish expedition, Spain conquered Cuba and appointed Spanish governors to rule in Havana. The administrators in Cuba were subject to the Viceroy of New Spain and the local authorities in Hispaniola. In 1762–63, Havana was briefly occupied by Great Britain, before being returned to Spain in exchange for Florida. A series of rebellions during the 19th century failed to end Spanish rule and claimed the lives of hundreds of thousands of Cubans. However, the Spanish–American War resulted in a Spanish withdrawal from the island in 1898, and following three-and-a-half years of subsequent US military rule,[1] Cuba gained formal independence in 1902.[2]
