Ostrovityanka [42]

Answer:

R = 0 and no population growth.

Explanation:

Birth rate may be defined as the growth of individual per thousand and death rate determines the death of individual per thousand in a year. The birth and death changes the population dynamics.

The growth rate depends on both the factors that are birth rate and death rate. Here, the birth rate is balanced or equal that replace the offspring father. The change in the population growth is same and the birth and replacement almost cancel out each other. In this case, the birth rate is zero and population do not grow.

Thus, the answer is  R = 0 and no population growth.

Nikitich [7]

According to lecture, the level of emission reductions pledged by individual countries at the paris climate agreements are sufficient to prevent dramatic climate change according to many scientists. <u>The statement is False.</u>

The issue is that many scientists believe the existing pledged emission reductions won't stop serious climate change.Leading the way in global efforts to combat climate change has been the EU. It played a key role in negotiating the Paris Agreement and continues to lead the world.

The EU presented its updated and improved NDC in December 2020, along with information to promote the ICTU (clearness, transparency, and understanding) of the NDC and a target to cut emissions by at least 55% from 1990 levels by 2030.

By working together, the EU and its Member States are committed to a legally-binding goal of a net domestic reduction of greenhouse gas emissions of at least 55% from 1990 to 2030.
