Answer: The Himalayas
Explanation: The Himalayas are the world's tallest mountains. They are forming as two continents collide. The Appalachian Mountains are the remnants of a larger mountain range.
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:
1) The statement is false
2) Option A) deoxyribose, phosphate, and a nitrogenous base
Explanation:
1) In semi-conservative DNA replication:
- a parent double-stranded DNA splits in two.
- Each strand is then read by the enzyme, DNA polymerase, to ensure accurate synthesis of a new daughter strand
- the newly synthesized strand contains nucleotides that are complimentary to free nucleotides present in the parent strand.
Thus, because the parent strand is retained in the newly synthesized DNA, DNA replication is described as semi-conservative
2) DNA consists of several repeating units of polydeoxynucleotides where each is made up of a nitrogenous base (Adenine, thymine, cytosine or guanine) linked to
deoxyribose sugar by an N-glycosidic linkage, and then the sugar linked to a phosphate group by phosphoester bond.
