An observation may generate a scientific question, which may lead to a hypothesis. The hypothesis can be tested the experimentation. The results of experimentation lead to changes in scientific knowledge.
Sample bias. It is a bias in that happens when a sample is collected in such a way that some members of the intended population are less likely to be included than others.
Answer:
Prophase II meiosis-chromosomes-6 and 12 DNA molecules per cell.
Explanation:
Meiosis is a unique type of division that occur in cells in which the chromosome number is decreased to half with the creation of haploid cells. It can be referred to as reduction division and it mostly occurs in organisms which go through sexual reproduction.
In prophase II , the nucleoli and nuclear membrane disappear.
The chromatids reduces in length to become short and thick .
The centromeres migrates to the polar regions and set the spindle fibres in place for the second meiotic division.
Therefore, at Prophase II of meiosis
The daughter cells are haploid. Its haploid cells should possess six chromosomes and 12 DNA molecules.
The answer is C) the mouse started running

Answer: Eight (8) different kinds of gametes can be produced by an individual with the genotype AABbCCddEeFf.
Explanation: Total number of gametes that can be formed can be determined by the formula 2^n where n is the number of heterozygous loci.
The heterozygous loci in the genotype AABbCCddEeFf are Bb Ee and Ff; n = 3
Therefore, 2^n = 2^3 = 2 x 2 x 2 = 8.
