Explanation:
Absolute age is defined as the numeric age of fossils.
To identify the absolute age of a fossil, the amount of certain radioactive elements in the rock are measured. When fossils are formed in the rocks, a small amounts of radioactive elements is included in it. The process to identify age of fossil using radioactive elements is known radiometric dating. So, radioactive isotope and its decay product gives absolute age of fossils.
Hence, the correct answer is "D".
Answer:
A. Miosis
B. DNA molecule
C. Body cells
D. phenotype
E. Recessive traits
F. genotype
G. Punnet square
H. nondisjunction
I. mitosis
J. sex cells
Explanation:
In meiosis cell division, a parent cell divides into four daughter cells whereas in mitosis, one cell divides into two daughter cells. If change occur in DNA molecules, mutation occurs. Phenotype refers to physical characteristics of an organism whereas genotype indicates genetic characteristics. Recessive traits only appears when the organisms have same traits or allele. Somatic cells is known as body cells whereas gametes is known as sex cells.
