Answer:
agricultural extension agent are train expert that acts as a middle man between the farmers and research institute or organisation. they are saddled with the responsibilities of bringing new innovations, technologies, knowledge e.t.c concerning agriculture to farmers and they in turn takes farmers concerns, complains and outcry to research institute.
they help to teach farmers on how too use modern farm tools and technologies. the extension agent use different methods to arouse or captivate the farmers and they are agent of change in that they help people form their own organizations in order to be able to tackle their problems.
they pass through different training and workshops and belong to a professional body before they can be certified an agricultural extension agent.Agricultural extension trainning/programmes cover a broad area including improved crop varieties, better livestock control, improved water management, and the control of weeds, pests or plant diseases. they are well paid and derive maximum satisfaction when helping farmers and proffering solutions to their problems.

Answer:
The recombination frequency between two genes exhibits a positive correlation with the distance between them, that is, farther they are, and more will be the chance of recombination. Thus, recombination frequency is used to signify distance among the two genes, for example, 1 percent recombination frequency demonstrates distance of 1 map unit.
Let us consider that the heterozygous female of genotype AaBb can generate four kinds of gametes, that is, AB, Ab, aB and ab. Of these, the two gametes are the outcomes of recombination, or it can be said that 50 percent are recombinants. Thus, it can be concluded that in case of two linked genes, the maximum probable recombination frequency is 50 percent.
This shows that any genes, which are distant than 50 map units will function as unlinked and will function as if they were on distinct chromosomes, and the frequency of recombinant frequency will be 50 percent.
In the given question, it is given that the map distance between the two genes is 80 map units, that is, more than 50 map units. The maximum probable recombinant offspring will be 50 percent of the entire offspring.

Lipids are good for making the cell membrane because they are stronger and block out things that should not be getting in out, for instance lipids mainly only let water and gases pass through.
