Answer:
256
Explanation:
If there are 2 pairs of chromosomes Aa and Bb, there are 4 possibilities for independent assortment of gametes:
A w B, aith with b, A with b and a with B.
If there are 3 pairs of chromosomes Aa, Bb and Cc, there are 8 possibilities:
ABC, abc, ABc, Abc, aBC, aBc, abC, AbC
This corresponds to 2^n, where n= the number of chromosomes.
Therefore, with 8 chromosomes, the possibilities are 2^8 = 256
This is for each parent.
Organelles float around in the cytoplasm.
The answer is oxidation or chemical weathering. There are three main types of weathering, which includes, mechanical weathering, biological and chemical weathering. Mechanical weathering is caused by wind, sand rain, thawing, freezing, and other forces that can physically alter the rock. Biological weathering is caused by the activities of plants and animals as they grow, nests and burrow. Chemical weathering is caused by chemical reactions rather than by mechanical means.
