Answer:

Explanation:

Several conclusions can be drawn from this observation;

1. The adaptation for fur colour in the mice from both location was similar, this could be because both environments have almost similar conditions.

2. It is also an indication that the dark fur colour may have evolved independently in both populations.

Answer:

I would say B is the answer.

Explanation:

An applied force is a force that is applied to an object by a person or another object. Example: pushing a box to the other side of a room.

A normal force is a force that surfaces exert to prevent solid objects from passing through each other. Example: resting a book upon a table.

Drag is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid. This doesn't really match the force we use.

However, an attractive force is a force by which one object attracts another. Example: two magnets pulling/colliding together. This is a good example of a force we exert on objects when it is pulled toward us.

GalinKa [24]

Answer:

It's an alarming situation about the decline of commercial fish population and we must need to develop the policy solution to this dangerous fisheries problem.

We can develop more fish by fish hatcheries to increase the population of fish and release large number of fish into the ocean.

We should give the awareness to the general public related to decrease the recreational fishing impact.

Commercial fishing must be ban until we reaches the sustainable level of fish.

There must be place international limits to every country related to limited number of fish they can take.
