Answer:
A
Explanation:
The fox's cells do not have a cell wall, since it is an animal, while the tree does, since it's a plant. B is not correct since they have reversed roles, C is not correct since both are biotic, and D is not correct since both are adapted to cold weather. Hope this helps!
Answer:
The long-term increase in the temperature of the planet Earth due to certain reasons such as human activities is termed as global warming. Global warming is a concern for scientists nowadays as its consequences are very harmful to life on Earth.
Global warming causes climate changes due to which survival in extreme heat conditions will become very difficult in the near future. The greenhouse gases will cause life on Earth to be dangerous as these gases when increase than normal will be toxic. The greenhouse gases are causing the ozone layer to get depleted without which life on Earth will not be possible.

The right answers are : b. nitrogenous bases c. phosphates d. sugars.
Deoxyribonucleic acid (DNA) is the genetic information of most living organisms (on the other hand, some viruses, retroviruses, use ribonucleic acid (RNA) as genetic information).
- DNA is a polymer, made of units called nucleotides (or mononucleotides).
- The nucleotide consists of a phosphate + a sugar + a nitrogenous base. In DNA, the nucleotide is a deoxyribonucleotide (in RNA, the nucleotide is a ribonucleotide).
The amoxicillin and the ampicillin are known to degrade the cell wall. both of these antibiotics have β- lactam in their structure. The structure of the ampicillin and the amoxicillin is similar having a single difference at the 4th position of benzene ring. The structure of the amoxicillin have an addition OH or hydroxyl group at the 4th position in the benzene ring.
As the structure of ampicillin and amoxicillin is similar, the bacteria having ampicillin resistance can also show amoxicillin resistance.
MODE OF ACTION OF AMOXICILLIN:
The amoxicillin binds with the pencillin binding proteins, present in the bacterial cell wall. The binding of the amoxicillin inhibits the enzyme transpepetidase, which is an important enzyme for the synthesis of the cell wall. it also inhibit murine hydrolases and inhibit the assembling of cell wall.
The amoxicillin effects the cell walls of the bacteria, as the animals cells do not have cell wall, they only have a cell membrane, the increase in the dose would not effect the animal cell.
