Explanation:
1] ADAPTATION : WE HAVE BEEN ADAPTING A DOG AS A PET. 
2] BIODIVERSITY : BIODIVERSITY IS THE VARIABILITY AMONG LIVING ORGANISMS FROM ALL SOURCES INCLUDING TERRESTRIAL, MARINE, AND OTHER AQUATIC ANIMALS
3] ISOLATION : THE PROCESS OR FACT OF ISOLATING OR BEING ISOLATED
4] VARIATION : DIFFERENCE BETWEEN ORGANISMS OR PLANTS

Answer:
Cada gen puede tener varias variantes, llamadas alelos, que codifican diferentes variantes del rasgo en cuestión. ... Los genes residen en los cromosomas de una célula, cada uno de los cuales contiene muchos genes. Cada célula de cualquier organismo individual contiene el mismo conjunto de cromosomas.

Answer: The correct answer is-
muscle, nervous, connective, and epithelial.    
Tissue can be described as a group of specialized cells that are clustered together to perform particular function.
There are primarily four main types of tissue, which are present in the human body. These tissues are-
Muscle tissue ( assist in locomotion and provides structural support to body).
epithelial tissue ( covers surface of body surface and forms internal lining in most of the organs), 
connective tissue ( such as bones, cartilage, blood) that is abundantly present in the body.
nervous tissue ( helps in the transmission of electrical signals through out body).
