Answer:
Water is important in chemical weathering because most substances dissolve in water.
The process of dissolving breaks up the minerals in the rock into small pieces. The small pieces mix with water to form.
Acids are also agents of chemical weathering and cause more chemical weathering than pure water does.
Answer: e.Woman; there is not enough information to tell if the nondisjunction happened in meiosis I or II.
Explanation: There is not enough information to tell if the nondisjunction happened in meiosis I or II. Nondisjunction can occur during meiosis I and meiosis II, resulting in abnormal chromosomes number of gametes. The important difference between nondisjunction in meiosis 1 and Ii is that during meiosis 1, homologous chromosomes fail to separate while in meiosis II, sister chromatids fail to separate meaning it could have happened in meiosis I or II but we were not given.

Answer:
The answer is 6.4 × 
Joules
Explanation:
This question wants to effectively test your knowledge of the names of the negative powers of 10, so first of all, before calculating, let me explain what each of the symbols in the units given in the question means:
Force = 8.0 pN = 8.0 × 
N
displacement = 8.0 nm = 8.0 × 
N
Now let us calculate the work.
work = Force × Displacement
work = 8.0 × × 8.0 × = 64 × 
= 6.4 × 
Joules (in standard form)
