Answer: Atmospheric Nitrogen is unreactive
Explanation:
The atmosphere is made up of about 80% Nitrogen, 16% oxygen, about 4% carbon dioxide, rare gases etc.
However, the 80% Nitrogen is highly unreactive, and needs to be trapped by competent micro organisms known as nitrogen-fixing bacteria in the root nodules of legumes.
Then, it is converted to several forms like nitrites, nitrates (easily absorbed by plants), ammonia and finally escape to the atmosphere again.
This brief illustration explains the NITROGEN CYCLE, and it is the only means by which plants and animals can use the highly unreactive nitrogen
Answer:
a. Fiber
Explanation:
The major nutrients required by humans in food are carbohydrates, proteins, fats, vitamins, and minerals. Our food also has dietary fibers and water. Dietary fibers or fibers are also known as roughage. Fibers are present mainly in plant products such as whole grains, pulses, fruits and vegetables. Fibers only add bulk and do not provide any nutrients to us. However, dietary fibers help the body get rid of undigested food.
Answer: Errors that occur during DNA replication lead to mutations, which represent permanent, heritable changes in genetic material. These errors can pass from parent cell to daughter cells and affect many generations of cells.
Explanation:
Answer:
A site
Explanation:
During the process of translation, ribosomes play a major role in connecting mRNA codons with tRNA anticodons. Ribosomes are composed of two subunits which consist ofproteins and rRNA. The tree sites of ribosomes are:
- P site or peptidyl site-this site binds to the tRNA which holds the growing polypeptide chain.
- A site or acceptor site-this is a site of peptide bond formation between the growing polypeptide and the next incoming amino acid
- E site or exit site-the site for the final binding of t-RNA .
