Nitro fixation is the process in which bacteria returns nutrients to the soil
Explanation:
Pollen grains are the male gametes in plants. It is present on the anthers. Pollen grains finds its way to the ovule by the process of pollination. The structure of pollen grains vary from one species of flower to another. The hibiscus and spider lily both have circular pollen grain.
However, the atomic structure of pollen grain of hibiscus represents the Buckminster fullerene but is not shown in spider lily. The pollen grains of hibiscus have spikes on its surface.
Answer:
The first, which was published in 2014 and included the review of 147 studies, concluded that GM crops have allowed an average increase in agricultural yield by 22 percent and increased farmers' profits by 68 percent, with profit margins even larger in developing countries.Explanation:
Plasmid is a small, circular, double-stranded DNA molecule that is distinct from a cell's chromosomal DNA. Plasmids naturally exists in bacterial cells, and they also occur in some eukaryotes. The genes carried in plasmids provide bacteria bacteria with genetic advantages, such as antibiotic resistance. To know whether the cell carry recombinant plasmids; only cells with a plasmid will reproduce and also the color of the colonies in E. coli plasmid recombination experiments allows scientists to distinguish colonies with recombinant plasmids from those without.
