In biology, a mutation is the permanent alteration of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA or other genetic elements. Mutations result from errors during DNA replication or other types of damage to DNA, which then may undergo error-prone repair, or cause an error during other forms of repair, or else may cause an error during replication. Mutations may also result from insertion or deletion of segments of DNA due to mobile genetic elements. Mutations may or may not produce discernible changes in the observable characteristics of an organism.

Allopatric speciation, the most common form of speciation, occurs when populations of a species become geographically isolated.
Answer: Hope this helps
GAS EXCHANGE: the intake of Oxygen and the expulsion of Carbon dioxide. In the capillaries of the alveoli, oxygen travels due to the concentration gradient into those capillaries. Carbon dioxide is then expelled from those capillaries.
RESPIRATORY MEDIUM: is air for animals and water for fish. It is basically the substance through with living animals receive their oxygen.
RESPIRATORY SURFACE: is where the gaseous exchange takes place. The oxygen and carbon dioxide move across the respiratory surface entirely by diffusion.
Answer:
Heterotroph
Explanation:
Hi, According to what I understand, the term is heterotroph, not hetrotrop [Tropism is concerned with how organisms react to a certain stimulus]
The word "heterotrophy" refers to organisms that do not synthesis their food or carbohydrates in the presence of photosynthetic pigment using CO2, water, or solar energy. With the exception of Euglena, they cannot synthesis their food or carbohydrates (it is unicellular and contains photosynthetic pigment). Carnivores, herbivores, etc. are heterotrophs.
