Answer:
A. and D.
Explanation:
If we go horizontally, from the left to the right on the periodic table, the electronegativity increases.
If the radius is small, that means the electrons are closer to the nucleus, which makes them more electronegative.
Antibiotics typically work as competitive enzyme inhibitors, they bind to enzymes and prevent them for being able to caring out certain metabolic processes. Antibiotics will effect only certain types of enzymes and typically humans may not produce these enzymes meaning it won’t have an effect on our cells but will kill bacteria. The thing is though we have “good” bacteria in our body that is also killed by antibiotics which in turn cause problems with digestion and other bodily processes. If you want an example of what an antibiotic does, it will prevent an enzyme in the bacteria from producing a membrane and it becomes easier for our bodies to attack the cell, white blood cells have an easier time killing the cell after the enzyme is inhibited. Also this is not to say that all antibiotics don’t affect human cells they may affect them slightly but typically bacteria is what’s killed
Answer:
The Mark B is the tRNA in the illustration
Explanation:
The process of translation requires four significant components within the cell
1. The mRNA, which is a product of transcription from the cells RNA or DNA, depending on the genetic part of the cell, as some cells have RNA while others have DNA. It bears the exons for the process of translation. Thus it is usually attached to the ribosome during the process of translation. This is mark A.
2. The tRNA, which generally forms a loop with one end used for the attachment of the right amino acid coded on the mRNA triplet codons. The illustration given in the question shows that the structure mark B is attached to Glycine. This showed that the structure is the tRNA.
3. The ribosome is the main structure where protein is being synthesized; it housed the mRNA and permit the input of the right amino acid for the formation of peptide bonds.
4. Amino acids are also essential for the production of protein during translation.
