Answer:
RNA nucleotides include sugar ribose, rather than the Deoxyribose that is part of DNA. Functionally, DNA maintains the protein-encoding information, whereas RNA uses the information to enable the cell to synthesize the particular protein.
Explanation:
Cell-wall inhibiting antimicrobial drugs be less effective on gram-negative bacteria compared to gram-positive bacteria because the outer membrane of the gram-negative bacteria inhibits penetration of the drug and the peptidoglycan found in gram-positive bacteria is structurally different from that in gram-negative bacteria.
Answer: Option B & C
<u>Explanation:</u>
Antimicrobial drugs are induced into a body to act on that particular selective bacterium which causes disease. When antimicrobial drugs are injected they act efficiently on the gram positive bacteria inhibiting the proliferation of the cells by acting on the cell wall so that cell multiplication doesn’t happen.
On the other hand it is hard to act on the gram-negative bacteria as it has a cell membrane that inhibits drug penetration into it. Both cell walls contain peptidoglycan but in the gram-positive is more assembled and layered while in the gram-negative it is just a thin layer. As gram-positive is thick layered it provides place for another molecule to attach to it but the thin layer in gram-negative inhibits it.
<em><u>By providing extension services and agricultural literacy in various ways to farmers, farm productivity and efficiency of farmers will improve, which will increase their income and uplift farmers' </u></em><em><u>standard of living </u></em><em><u>from the bondage of </u></em><em><u>poverty</u></em><em><u>.</u></em>
<em><u /></em>
Standard of living refers to the level of income, material possession among others that are available to an average person which makes life comfortable.
The following are ways I can help improve the standard of living of farmers as an extension worker:
- Educate farmers on the need to adopt innovations that increases efficiency in farm production.
- Design demonstration fields where new improved ideas can be demonstrated to show farmers how they work.
- Organize agricultural literacy programs for farmers on how to make the best use of local resources in catering for their homes and living healthy.
- Visit farmers from time to time to encourage and ensure farmers are adopting new technologies that will improve their farm production and income.
- Serve as a link between farmers and research institute, in order to solve existing problems faced by farmers in their farms.
- Training of farmers on how to keep proper farm records.
- Provide up-to-date and reliable weather forecast for farmers.
The above listed ways among others, will ensure farm productivity and efficiency, which will in turn increase the income and standard of living of farmers as well as fight poverty.
