Answer:
Long before Darwin and Wallace, farmers and breeders were using the idea of selection to cause major changes in the features of their plants and animals over the course of decades. Farmers and breeders allowed only the plants and animals with desirable characteristics to reproduce, causing the evolution of farm stock. This process is called artificial selection because people (instead of nature) select which organisms get to reproduce.
The two cell organelles involved in energy conversion are chloroplasts and mitochondria.
Chloroplasts are found plants. They are the photosynthesizing organelles of all photosynthetic eukaryotes.
Mitochondria are found in both plants and animals. It converts food such as sugars into the chemical ATP, the main source of energy for cell work.
Both organelles are said to evolve through a process called "endosymbiosis".
A cell membrane is also called...A. the plasma membrane.
Answer:
b) Systematics
Explanation:
Darwin presented the theory of evolution and explained that the process of evolution occured because of natural selection which further explains that offsprings are produced from organisms and these organisms are able to survive in their environment.
As systematics is the branch of biology, which basically deals with evolutionary relationships of the organisms .Thus the darwin theory of evolution will be considered in the field of systematics.
Hence the option B) Systematics is the right option.
Not a physical change, It's a chemical change because you can't change the process back to its original state. If it was a physical change, you could change it back to its original state using the boiling, evaporating or melting process.
