Answer:

When they find the river they came from, they start to use smell as a navigator to find their way back to their home stream. They develop this ability ("smell memory bank") when they start migrating to the ocena as young fish.

Scientists believe that salmon navigate by using the earth's magnetic field like a compass. When they find the river they came from, they start using smell to find their way back to their home stream. They build their 'smell memory-bank' when they start migrating to the ocean as young fish.

Explain the functions of the political parties and their role in the electoral process at state and local levels
VMariaS [17]

Answer:

Political parties perform an important task in government. They bring people together to achieve control of the government, develop policies favorable to their interests or the groups that support them, and organize and persuade voters to elect their candidates to office. Although very much involved in the operation of government at all levels, political parties are not the government itself, and the Constitution makes no mention of them.

How have people adapted physically to different environments? Why do you think these differences developed?
Karo-lina-s [1.5K]
That's a simple part of evolution. Humans are built to adapt.

If we go in the frozen tundra, we make coats and other cold-blocking clothes. We find nearby food, like fish. Over time, our differences become more distinct from the rest, and we become less vulnerable to the cold.

Hope this helps! :)
