Why are human populations not limited by the carrying capacity of their ecosystems

1 answer:

6 0

The human populations are not limited by the carrying capacity of their ecosystems, and they are the only species on Earth that are able to perform such a thing. The main reason for this is that the humans are able to transport resources of all sorts and for all needs from very distant places. Even if there's a very large population surrounded by desert, the humans are still able to survive by simply bringing in the necessary things from other places throughout he means of transportation. Another reason is that the humans are able to change and manipulate their environment to certain extent, being able to provide for themselves even in ecosystems that naturally are nowhere near close to provide those things for them.

Why do melting ice caps make Earth warmer?

frozen [14]

Why do melting ice caps make Earth warmer?

The correct answer is C. Albedo decreases.

When the albedo is lower, more radiation from the Sun gets absorbed by the planet resulting in rise of temperature. When the snow covered area warms up and melts, the albedo goes down and more sunlight is absorbed in that area and the temperatures increase.

A new mutation arises in one person on the island of Kiribati (human population size 100,000). Assuming this particular mutation

tatuchka [14]

Answer:

0.999999 ≈ 1

Explanation:

In a population ( N ) there is the presence of 2N alleles in the population also chance of fixation can be expressed as ; 1/ 2N

Therefore the probability that the mutation will be lost due to genetic drift

= 2N - 1 / 2N ---- ( 1 )

given that ; N = 100,000

back to equation 1

P ( losing mutation due to genetic drift ) = ((2*100,000) - 1 )) / ( 2* 100,000 )

= ( 200,000 - 1 ) / 200,000

= 0.999999 ≈ 1
