Overfishing of salmon has caused populations of wild salmon to decline. To combat this decline, salmon are raised in hatcheries, and then released to the wild. However, researchers have found that hatchery-raised salmon have reduced reproductive success in the wild, compared to wild salmon. They have also identified many genetic differences between hatchery-raised and wild salmon.

Answers

Answer 1

The differences in the wild and hatcheries make it so the different salmon adapt differently and have different traits.

If salmon are split up into different habitats, one being in the wild and one being in captivity, they will eventually have different adaptations from each other and their offspring will develop traits that are better suited for their environment.

Wild salmon and salmon that are raised in captivity are going to be very different from each other. The salmon in captivity do not have to actively hunt for their food, be wary of certain predators, or may not want to reproduce.

Taking these factors into account, it is very possible that the salmon raised in captivity will have reduced reproductive success compared to the salmon that thrive in the wild. Along with this, they would most likely have many genetic differences from each other and other traits that better adapt to their living situations.

Explanation:

The Gilded Age saw a huge increase in the number of immigrants entering the country, with thousands of people flocked in for a promised American dream experience, where the opportunities were infinite in the new world. However, the experience of the real world was different from what they expected because their life was riddled with significant economic struggles and social upheaval. Many Americans felt high levels of animosity towards immigrants coming into what they felt was their country and that animosity spilled over not only into the workplace but also in various social environments.

Why were England's colonial policies from the early 1600s to mid-1700s termed "neglect"?

Infectious diseases caused many colonial cities to be abandoned.

The government refused to protect the colonies from attack.

Colonial economies collapsed and most colonists had little money.

The government did not enforce its laws and trade restrictions.

Answers

The correct answer is D) The government did not enforce its laws and trade restrictions.

England's colonial policies from the early 1600s to the mid-1700s were termed "neglect" because the government did not enforce its laws and trade restrictions.

We are talking about the heavy taxations acts imposed by the English monarchy to the 13 North American colonies. This taxation caused anger among the colonists because they considered that the British government abused and tried to exploit the colonies to pay the many debts they had in England.

There were many acts that upset colonists such as the Navigations Acts, the Stamp Act, or the Tea Ac, among, many others. And the worst part was that the colonists had to pay taxes but had no voice or representation in the British Parliament.

These issues were causes of the American Revolutionary War of Independence.
