However the process presents more of a challenge for aquatic plants if they are fully submerged below the surface of the water. Cells without dna have limited specialized functionality.

For example a maturing red blood cell expels its nucleus containing dna to increase oxygen capacity. Misconceptions about evolutionary theory and processes. Evolution is a theory about the origin of life. Evolutionary theory does encompass ideas and evidence regarding life s origins e g whether or not it happened near a deep sea vent which organic molecules came first etc but this is not the central focus of evolutionary theory.

Without a nucleus mature red cells cannot grow divide or pass along genetic material. Genetic variation in a population is derived from a wide assortment of genes and alleles. The end products of natural selection are organisms that are adapted to their present environments. Pct of nephron and lining of intestine b.

Cells without a nucleus wear out quickly and die. Photosynthesis involves the same molecules and chemical reactions in land plants and aquatic plants.

These genetic changes are not present in a parent s egg or sperm cells or in the fertilized egg but happen a bit later when the embryo includes several cells. Loss of habitat and loss of genetic variation. The outcome of evolution is not a perfectly designed organism. As all the cells divide during growth and development cells that arise from the cell with the altered gene will have the mutation while other cells will not.

Dinosaurs for instance lost their habitat about 65 million years ago the hot dry climate of the cretaceous period changed very quickly most likely because of an.
