RELATIVE DATING is a way to estimate the order of geologic events by using rock layers, index fossils or other methods.
Relative dating is used by geologists to arrange geological events in sequential order. Relative dating usually use six principles to determine the relative age of any rock or fossil. The principles are: principle of superposition, principle of original horizontality, principle of lateral continuity, principle of cross cutting, principle of inclusions and principle of fossils succession.

Humans experience two growth spurts. The first one occurs in early childhood at around the ages of 2 to 3, during which a child grows at a rate of 4 inches<span> per year on average. The other growth spurt happens during puberty. Girls grow about </span>3<span> to </span>3<span> ½ inches per year, and boys grow about </span>4 inches<span> per year during puberty.</span>
Active transport uses up energy while passive transport does not.
Phenotype - short , Tall
Genotype - tt (short) , TT or Tt (tall)
<u>Explanation:</u>
In Mendelian Genetics, <em>Dominant traits</em> are represented by capital letters and <em>Recessive traits</em> are represented by small letters.
So if height is the character considered, then the traits would be short and tall.
Tall is the dominant phenotype and short is the recessive phenotype.
The alleles of the gene for height are T and t.
The genotype for Tall trait is TT or Tt.
The genotype for short trait is tt.
Therefore, the symbol representation of phenotype (Tall) is TT or Tt and for phenotype (short) is tt.
