Answer:
Charles Darwin spent almost 5 years in the voyage name HMS Beagle. This voyage made him famous as after returning, he formulated the "Theory of natural selection" as he was amazed by the geographical distribution of the wildlife and also collected fossils that helped him to formulate his theory.
Explanation:
Charles Darwin was the main contributor to the theory of evolution. Besides, he was a geologist, naturalist, and biologist. He first demonstrated the branching pattern of evolution on the basis of natural selection. 18 February 1809 was his birth date and he died in 1882. He explained the theory of natural selection with the help of finches residing in the Galapagos island. The change in the beak structure of the finches according to the availability of food illustrates the process of natural selection and hence the process of evolution.
Answer:
A)All organisms are composed of one or more cells.
B)All cells have membrane-bound structures that have certain functions.
D)The cell is the basic unit of organization on organisms.
Explanation:
Created by Mathias Scheiden and Theodor Schwann, Cell Theory involves the assertion that all living beings are formed by cells and that these cells have functional structures, which was possible as a result of the development of microscopy, being, today, a of the most important generalizations in the field of Biology.
In addition, according to cell theory, the cell is the smallest unit of life, and new cells are formed from the division of cells that already exist, and this process occurs from cell division. Another important pillar of this theory is the fact that the cell is the unit of reproduction and transmission of inherited characteristics, that is, all genetic characters transmitted from parents to children, are transmitted from one cell to another in the process of reproduction.
In summary, cell theory states that:
- All organisms are composed of one or more cells.
- All cells have membrane-bound structures that have certain functions.
- The cell is the basic unit of organization on organisms.

Answer: lymphatic circulatory; respiratory
Explanation:
The autonomic nervous system controls the internal body functions and responses which are not under the voluntary control. The functions control by the autonomous nervous system are heart rate, body fluid circulation, respiration, urination, sexual arousal and pupillary response.
The lymphatic system is one of the part of the circulatory system, it consists of a network of connected tubes called as lymphatic vessels. These vessels distribute the lymph fluid throughout the body. The lymph fluid consists of white blood cells which provide immunity against the pathogen.
The respiratory system is the system which controls the exchange of gases (Carbon dioxide and oxygen) between the body and the environment.
Both lymphatic circulation and respiration are the two functions controlled by the autonomic nervous system.
