Mono hybrid cross dihybrid cross homozygous cross heterozygous
2. High birth rate, zero death rate, high immigration, zero emigration
This is because birth rate and immigration increase population size, and death rate and emigration decrease population size, so maximizing the former and minimizing the latter are ideal
The law reduced acid rain and improved public health by dramatically reducing emissions of sulfur dioxide (SO2) and oxides of nitrogen (NOx).
The plantae kingdom has an overwhelming majority of the producers, this may not be true. The producers are mostly present as autotrophs that make food using the sunlight. Other kingdoms like the bacteria have varied forms of producer, both the autotrophs like the cyanobacteria and the chemotrophs like halothiobacillus that use the internal heat of the Earth at the bottom of the dark ocean floor to synthesise their food.
Competition allows science to advance at a faster pace.
Think of it as an arms race: when a country builds one battleship, their enemy builds two. This continues as both countries try to outdo each other. Competitive science works the same way.
