Answer:
Explanation:
Many animals have developed specific parts of the body adapted to survival in a certain environment. Among them are webbed feet, sharp claws, whiskers, sharp teeth, large beaks, wings, and hooves. In most aquatic animals, swimming is a must.
They're mineral ions.
Examples are calcium and iron
They can prevent diseases such as ricket (soft bones) and anaemia (not enough blood)
Serotonin norepinephrine reuptake inhibitors (SNRIs) were first introduced as a class of antidepressants in the mid-1990s.
The similarity of 94% in their DNA sequence suggest that they have originated from a common ancestor and are closely related species.
Explanation:
The difference in DNA sequences in different species is due to the accumulation of genetic variation in the course of natural selection and evolution. Less is the difference in DNA sequences of two organisms the more related they are.
Genes determine the characteristics in an organism, and they are DNA sequences determining the protein to be formed. The similarity in DNA sequence of two species establish the evolutionary relationship among them.
Due to the genetic variation in species, the natural selection of the species had caused the evolution of the species adapted well to the environment.
Answer:
The correct answer is - the biofilm.
Explanation:
Biofilms are a type of one or more than one type of microbes that grow on many different surfaces, These microbes include fungi, bacteria, and protist that develop attached to the surface and one another and embedded in a self-produced matrix.
It is a thick film of protein such as fibrin, polysaccharides such as alginate or eDNA secreted by the bacteria, and other microbes that cover the teeth surface.
