It is the wear and tear theory of ageing.
The wear and tear theory defends that ageing is caused by the damage that happens as time goes by to cells and body systems. The name of the theory reflects this idea of wearing out - the organism is worn out and doesn't function normally. This is the theory that's accepted more generally as common sense but there are other theories of ageing that see the process as a more intentional process.
The correct answer is a density-independent factor.
Density-independent factor refers to any factor that restricts the population size, and whose influence is not reliant on the number of people in the population. An example of such a factor is a hurricane that will eradicate or kill all the individuals of the population, which comes under its influence irrespective of whether the size of the population of large or small.

The mass does not change, the only thing that changes is the weight (that is the force attributed to gravity mg)
Yes, because if you're close to the sea then you will be in a warmer climate. and Ocean currents affect climate in a way similar to winds. Ocean currents move water around the ocean. Warm water currents are currents that move water away from the equator, and cold water currents are currents that move water away from the poles.
Places that are near warm water currents will have a warmer climate.Places that are near cold water currents will have a colder climate.
