In a population of rabbits, there may be several different colors, light brown through dark brown, with many shades in between.
____________________ provides for this variation in the population of rabbits. This variation is the basis for natural selection. A) Immigration B) Sexual reproduction C) Genetic engineering D) Changes in the environment
Explanation: The process that provides variation to the species is sexual reproduction. The sperm and the eggs that fuse together to form zygote can have multiple combinations of chromosomes.
These different combinations provide variation in the species. These variation are the foundation of natural selection. The fittest organism survive and reproduce and the unfit organism does not survive.
Example: Different fur color of rabbits (white, light brown, dark brown).
Prokaryotic cells do not have membrane bound organelles. Eukaryotic cells do have membrane bound organelles. The membrane controls movement in and out of the cell. ... The cytoplasm fills the space between the nucleus and the cell membrane.
