Explanation:
Heredity (inheritance) is the transmission of genetic information and traits from parents to offspring through genes. Variation refers to differences among individuals, evolution is the change in heritable traits over generations, and mutation is a change in DNA sequence. Mendel's laws describe the patterns of heredity. Genes are the units of heredity.
Explanation:
Mature human RBCs have a lifespan of approximately 120 days, after which they are phagocytosed by macrophages in the spleen and liver. They lack nuclei and organelles, thus cannot repair themselves. New RBCs are produced in the bone marrow at a rate of about 2 million per second. Erythropoietin stimulates RBC production.
