Amoxicillin is a broad-spectrum antibiotic widely used for certain
bacterial infections in the ear, nose, throat, genitourinary tract, skin, lower
respiratory tract, and its also used to treat gonnorhea. Amoxicillin is a
fairly strong drug, and it can elicit an allergy to patients even to those who
had used the drug before and did not experienced any untoward problems. If the patient
had symptoms such as difficulty in breathing, itching, and untoward swelling or
lump in the throat when receiving treatment with penicillins like amoxicillin,
sulbactam, ampicillin, methicillin, or penicillin G, the nurse should
discontinue giving amoxicillin and report to the doctor right away.
Answer:
Because proteins and lipid tails are free to move and are not bonded by strong interactions with each other.
Explanation:
The plasma membranes have two layers of phospholipids in which proteins are present. The hydrophobic fatty acid tails of phospholipid layers make the inner core of the membranes. However, the tails are not bonded to each other and make a fluid-like base in which proteins are present. Also, the membrane proteins are not bonded to the phospholipids and are free to change their position within the phospholipid leaflets. This is why the model is described as a fluid mosaic model.
Answer:
They release energy as they degrade polymers to monomers.
Explanation:
In a catabolic pathway, complex hydrocarbons are usually broken down to their monomeric units.
This breaking down leads to the release of energy.
- Anabolic pathway leads to the build up of energy. One of such process is photosynthesis.
- The catabolic pathway breaks down compounds to simpler units in order to release energy.
Before
Principle of superposition of strata
Younger
Principle of cross cutting
Explanation:
Relative dating is method of assigning ages to geologic events in nature. This is based on certain principles and laws proposed by earlier geologists.
Relative dating differs from absolute dating in that absolute dating assigns real quantitative numbers to geologic events.
- From the analogy of the building provided, according to the principle of superposition of strata, the oldest layer is at the bottom of the sequence and the youngest on top.
- The lowest part of the section must of the section must have been constructed before the parts above it were constructed.
- Based on the principle of cross cutting "geologic features that cuts another are usually younger than the sequence they cut through ".
- The cracks on the wall is cross-cutting feature that appeared after the wall was formed.
- Therefore, it is younger than the wall.

Basically structure of DNA is very important in the process of replication.
DNA molecules have antiparallel structure i.e. the two strands of the halix run in opposite directions of one another. Each strand has 5 prime end and 3 prime end. Solving the structure of DNA unlocked the door to understanding many of the function of DNA, such as how it copied and how the information it carries can be used to produce protein.
