Answer:
Agriculture gave people the opportunity to create civilizations, fight hunger and work to combat challenges in population growth and climate change.
Explanation:
Another positive development in farming is the rapid expansion of farmers markets. Farmers markets allow small farmers to interact directly with consumers. The food system remains within the local economy by being locally produced and eliminates the need for long-distance transportation. The opportunity to purchase locally grown food proves invaluable as the demand for it rises.
Answer:
Hello your question is poorly written, the options and the question is all mixed up but i was able to pick out the correct answer.
answer <em>: A thin liquid layer that is chemically bonded to the interior of a capillary column that comes in contact with an inert carrier gas or mobile phase</em>
Explanation:
The stationary phase in gas Chromatography is best described as ( from the options listed in your question ) :
<em>A thin liquid layer that is chemically bonded to the interior of a capillary column that comes in contact with an inert carrier gas or mobile phase</em>
Gas chromatography is an analytical process used to separate the chemical components ( usually gases ) found in a mixture sample
Answer:
b: 8;8
Explanation:
Mitotic or meiotic cell division constitute the m phase of the cell cycle. At the end of the m phase, the new cells enter the interphase stage of the cell cycle. The interphase is further sub-divided into;
- <em>the
phase,</em> - <em>the
phase,</em> - <em>the S phase; and</em>
- <em>the
phase</em>.
The phase is essentially a resting phase. Cells that do not need to divide except when necessary move into this phase after exiting the m phase.
Actively dividing cells enter the phase after exiting the m phase. Cell development and growth takes place. From there, the cells enter the S phase where DNA replication/synthesis takes place. The cells then enter the phase where proteins are synthesized in preparation for division or m phase.
At the S phase, the amount of DNA a cell carries is doubled but the chromosome number remains the same. For example, if a cell enters the S phase with 2 g of DNA containing 10 chromosomes, at the end of S phase, the amount of DNA would have come 4 g while the number of chromosomes will remain 10.
Hence, if the average amount of DNA in the assayed cells immediately after mitosis is 4 picograms, the amount would be 8 picograms at the end of S phase and will still remains 8 picograms at the end of phase.
The correct option is b.
RNA molecules attach to codons when the ribosome reaches the start codon.
Explanation:
The start codon initiates translation of the mRNA by the ribosome into a polypeptide. When the ribosome finds the start codon, it attaches to the mRNA and the first amino acid, methionine, is recruited. The ribosome then continues translating the rest of the mRNA until it encounters a stop codon that initiates the ‘knocking off of the ribosome from the mRNA.
