Bacterial cells are easy to grow, maintain, and manipulate in a lab which make it easy to use in recombinant DNA tech.
Answer:
When a population is in Hardy-Weinberg equilibrium for a gene, it does not evolve and allelic frequencies will remain the same for generations.
There are five basic Hardy-Weinberg assumptions: there is no mutation, the mating is random, there is no gene flow, the population size is infinite and there is no selection.
If the assumptions are not met for a gene, the population can evolve for that gene (that is, the allelic frequencies of that gene may change).
The mechanisms of evolution are violations of the different Hardy-Weinberg assumptions: mutation, non-random mating, genetic flow, finite population size (gene drift) and natural selection.
A community should use sustainable practices to produce food because "it protects the environment, farming communities and farmed species".
<u>Answer:</u> Option B
<u>Explanation:</u>
The practice of sustainable food production is a united network that integrates several components with the development of each and every individual covered in the food chain in order to protect the environmental, economic and social well-being of a community.
The advantages of such practice are production of less greenhouse gases, fossil fuel utilization is minimized and more dependent on human labor inspite of chemicals and energy-intensive technology. Sustainable farms conserve scarce water resources, encourage biodiversity and build healthy soil through composting and planting techniques that cover crops.
