Answer:
Columbian Exchange
Explanation:
The contact between Europe and the Americas produced what is known as the Columbian Exchange: the wide transfer of plants, animals, foods, human populations (including slaves), communicable diseases, and culture between the Eastern and Western hemispheres.
Answer:
Photosynthesis is the process by which certain organisms such as plants or bacteria, through the use of sunlight, synthesize carbon dioxide and convert it into glucose, thus generating the very food that said organism consumes for its own survival. In addition, residual to this chemical process, these organisms produce the oxygen that the rest of the living beings need to live.
That is why vegetation is so important for the development of life, as it functions as a lung that oxygenates the planet and allows living beings to carry out their lives normally.
Answer:
None of the options justify the reason they are true long distance migrants
Explanation:
From the passage, they are true long distance migrants because they nest in coastal wetlands of northern Europe but FLY SOUTH FOR THOUSAND OF MILES TO SPEND THE EUROPEAN WINTERS IN ANTARCTICA.
The highlighted statement above explains why they are true long long term distance migrants because they live in northern Europe but have to travel down south to enjoy winter. This distance from the north to the south is a very far distance from what can be inferred from the passage.
So therefore, Arctic terns are true long distance migrants as they nest in wetland northern Europe but travel south to enjoy winter in Antarctica.
Because the molecules that make them up move closer together and become more compact
