Answer:
endosymbiosis
Explanation:
The theory of endosymbiosis states that mitochondria in cells are once the descendants of aerobic prokaryotes. These prokaryotes used oxygen in order to generate energy. The mitochondria and the chloroplast are among the most important organelles that support endosymbiosis.
Marine biologists study changes in the ocean. so they will look at the chemical composition of deep waters and see how consecrated the oxygen is. They will also study the movements of the plates because when planted move it usually makes new food for deep life
they will also check animal concentrations in certain areas.
Another thing they do is track animal movements. this could be by putting a tracker on a whale or a shark or anything and watching its depths it goes or watching the distance it goes in a day.
Answer:
an introduced species.
Explanation:
An introduced species, often referred to as exotic species or invasive species, is term that describes species of either plants or animals that are not native to the place ore area in which they are being introduced, either as a result of accident or deliberate movement by human activity or external factors.
Common examples of animals that are introduced species are:
gypsy moth in eastern North America, the zebra mussel and alewife in the Great Lakes, the Canada goose and gray squirrel in Europe etc.
Notable example of introduced species of plants are:
the kudzu vine, Andean pampas grass, and yellow starthistle.
Hence, Purple loosestrife, Lythrum salicaria, being native to Europe, and taken to United States, is considered to an introduced specie.
