Answer:
8. B. we see comets when they approach the sun.
9. A. the sun's surface.
The correct answer is B. Cells divide, producing more cells.
Explanation
The cell is the basic unit of life for all living things. Likewise, it is a form of classification for them since living organisms can be classified according to the number of cells they have unicellular (a single cell), multicellular (more than one cell). In organisms that have more than one cell, they divide to produce more cells and form the organs and tissues themselves. Cell division can occur from two processes that are mitosis and meiosis in which two and four cells are produced respectively. According to the above, the correct answer is B. Cells divide and producing more cells.
The Amazon Basin is located in brazil. For centuries, this has protected the area, people, and the animals residing in it. Forest recession has occurred in the past 30 years due to increased industry and population growth through road projects, settlement initiatives, and industrial development.
The Amazon Basin includes a diversity of traditional inhabitants as well as biodiversity in both flora and fauna. These peoples have lived in the rain forest for thousands of years, and their lifestyles and cultures are well-adapted to this environment. Contrary to popular belief, their subsistence living methods do not significantly harm the environment. In the past few decades, the real threat to the Amazon Basin has been deforestation, poaching, and cattle ranching by transnational corporations.
Oil and gas development often also takes a heavy toll on the environment and local people; especially in rainforest areas where it can cause displacement of local people, air and water pollution, and construction of roads that open previously inaccessible areas to deforestation.
That said, even a new NASA study shows that over the last 20 years, the atmosphere above the Amazon Basin has been drying out, increasing the demand for water and leaving ecosystems vulnerable to fires and drought. It also shows that this increase in dryness is primarily the result of human activities.
Summary: all impacts caused by human development in the Amazon Basin is causing the atmosphere to go bad, the crops and indigenous plants to die at alarming rates, the water to be polluted, and the animals and humans who are indigenous of the area suffer the consequences.
