Analogous Structures. These are the saber teeth of Thylacosmilus and Smilodon. Both have saber teeth but they do not share an ancestor. Thylacosmilus is a marsupial and Smilodon is a mammal.
C is the answer to this question.
Answer:
all of the above
Explanation:
Water biomes describe all the living things living in an area of water such as a lake or ocean. The surrounding environment plays a huge part in what organisms able to live there.
For example, green plants and algae require sufficient sunlight and oxygen to perform photosynthesis. Green plants and algae are an important food source for many other organisms. The amount of salt is important for various fish, as they will be unable to survive in very high salt concentrations. Therefore, all of the above are limiting factors.
Ans.
-A species may defined as the largest group of organisms, which are similar to each other and show ability to interbreed and produce fertile offspring. Genetic diversity is defined as total number of genetic features in a species' genetic makeup.
-Natural selection results in evolution, when characteristics in organisms of species with greater survival and reproductive rate than other organisms of a population transmit to their offspring. Over many generations, individuals of one species evolve into other species, due to gradual modified characteristics.
-Mutations are defined as permanent, hereditary changes in genetic material or DNA. Change in DNA of an organism over successive generations leads to change in a population's genetic composition that results in evolution.
