Some mice have either a kinked tail or a normal tail. Kinked tails (K) are dominant. Located on another chromosome is the gene for growth. This gene can either be dominant, causing
normal growth (N), or it can be recessive (n), causing obesity in the mouse. Two mice that are
heterozygous for a kinked tail and heterozygous for normal growth are crossed. What is the
phenotype ratio resulting from this cross?

the principles and empirical processes of discovery and demonstration considered characteristic of or necessary for scientific investigation, generally involving the observation of phenomena, the formulation of a hypothesis concerning the phenomena, experimentation to test the hypothesis, and development of a conclusion that confirms, rejects, or modifies the hypothesis.

the wetland preservation movement began in the u.s. in earnest with the clean water act (cwa) of 1972. although not specifically written to protect wetlands, the cwa is comprised of a series of regulations designed to prevent pollutants from contaminating u.s. waters.

1. law of superposition: when there are horizontal layers of rock. the layers at the top are the youngest.

2. law of uncomformity: where one layer is much younger than the previous one, therefore creating a gap in the time record.

3. inclusion: when there is a solid stone inside of another.

4. intrusion: a feature formed when a stone is filled with magma.

hope i answered your question.
