Yes it is.
Carbon dioxide goes through plants, which they turn into oxygen. Humans and animals take in the oxygen and breathe out carbon dioxide. Then it repeats.
The question is incomplete as it does not have the options which are-
1. narcotic analgesics
2. non-narcotic analgesics
3. anti-psychotic barbiturates
Answer:
Non-narcotic analgesics
Explanation:
Non-narcotic analgesics are the drugs used medication to treat and control the inflammation and pain. They are used to treat mild to moderate pain usually but with other medications to treat severe pain like Advil, Tylenol and other.
The drug act by preventing the perception of the pain stimulus by blocking the transmission of the impulses generated in response to pain to the central nervous system.
Thus, Non-narcotic analgesics is the correct answer.
If none of the nucleotides includes stop or start codons when a segment of a gene contains 27 nucleotides there will be 81 amino acids in this segment code.
Answer: Option B
<u>Explanation:</u>
Codon is a nucleotides within messenger RNA. A stop or start codon is a nucleotide triplet which signals protein termination. Start codons initiate to start translation while the stop codon initiates termination.
The genetic codes are the sequence for nucleotide that codes for amino acids. A segment containing 27 nucleotides multiplied by 3 gives 81 amino acids. Every nucleotide in an mRNA are read “three at a time”. Hence this segment codes for 81 amino acids.
Explanation: Bacteria are needed in the nitrogen cycle because plants and animals cannot directly use atmospheric nitrogen. Bacteria in the roots of plants trap nitrogen and convert it to ammonia and other nitrogen compounds which plants can then use to make protein
