It is important because it breaks down the food eaten by the animals into nutrients which are needed for their bodies to function well. Not only it is important to animals but also to humans. <span>Food and drink must be changed into smaller molecules of nutrients before the blood absorbs them and carries them to cells throughout the body.</span>
Answer:
(1). symbiont
Explanation:
The bacterium inside the human intestine is a symbiont and the bacterium-human interaction is a symbiosis of the commensalistic type.
Commensalism is a biological interaction (symbiosis) in which members of one species -in this case the bacterium- gain benefits while those of the other species -in this case the human- neither benefit nor are harmed.
study suggests that photosynthetic eukaryotes may have emerged around 1.9 billion years ago in freshwater habitats. Eukaryotes are thought to have evolved the capacity for photosynthesis through a process called endosymbiosis, in which a protist host encapsulated a photosynthetic cyanobacterium.
Answer:
nonsense mutation
Explanation:
In DNA, the uracil (U) is replaced by thymine (T). If a change in the DNA sequence, or mutation, of a gene occurs that creates a stop codon, this is called a nonsense mutation.
