Weathering is a process that breaks down or changes rocks into smaller
pieces. Various atmospheric aspects are responsible for weathering
processes. Weathering is different from erosion. Erosion is the movement
of rock pieces and sediment from one area to another. Weathering is the
breaking down of rocks and erosion is a wearing away of rocks. There
are two main types of weathering: physical (or mechanical) weathering
and chemical weathering. Quite often, both forms of weathering will
occur together
Physical weathering is also known as mechanical weathering. This type of
weathering occurs when rocks and other landforms are broken down by
physical factors in the environment. These physical factors include
wind, water, sun, ice and temperature changes
Answer:
B) sympathetic nervous system
Explanation:
The sympathetic nervous system controls the way the body quick involuntary response to harmful or stressful situations. A rush in hormones rapidly occur to quicken the body's alertness and heart rate to release extra blood to the muscles

Answer;
D. Meiosis ii of mother
Explanation;
-The non-disjunction occurs in the meiosis II of the mother. This non-disjunction occurs when the two sister chromatids X and X fails to separate during meiosis II and produces an egg having two X chromosomes.
-Klinefelter syndrome is a condition that occurs in males when they have an extra X chromosome. The syndrome is not inherited, but usually occurs as a random event during the formation of reproductive cells (eggs and sperm) that results in the presence of one extra copy of the X chromosome in each cell (47,XXY).
