The statement is False.

Explanation:

The number of live birth per year in a population is referred to as birth rate.A high birth to death ratio indicates greater number of  live births than death in a population.When the number of individual born exceeds the number of individual died then the population size steadily increases resulting in a large population.Thus we conclude that, A high birth to death ratio leads to larger population.

answer: - b cells

explanation: -

there are many types of white blood cells present in our body. one such class of white blood cells are the lymphocytes. the b cells belong to the lymphocyte class of wbcs. the b cells perform their action against the pathogen by producing specialised proteins called as antibodies. these antibodies are produced as and when the b cells encounter pathogens in response to the antigens present on the surface of the pathogen. these antibodies bind to the antigens present on the pathogen and then, target them for destruction by other cells of the immune system.

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.
