Answer:

Embedded in a lipid bilayer. (Ans. C)

Explanation:

Fluid mosaic model explains different observations such as the structure of functional cell membranes. According to this model, there is a thin polar membrane composed of a two-layer of lipid molecules called lipid bi-layer or phospholipid bi-layer in which proteins molecules are embedded. This layer provides fluidity and elasticity to the membrane structure.

These membranes form a continuous barrier around all cells and they are a flat sheet in structure. The lipid bilayer is working as a barrier that keeps proteins, ions and other molecules where they are needed to be and preventing diffusing them to other areas. They are impermeable to most hydrophilic molecules. They are particularly impermeable to ions, which allow cells to regulate pH and salt concentration in membrane through the transport ions across their membranes using proteins knows as ion pumps.

If someone told you that plate tectonics is just a theory and that it hasn’t been accepted as a law yet, how would this informat
ch4aika [34]

Answer: There are few ‘laws’ in science. Those ‘laws’ are so named for historical reasons, but they are theoretical in nature. They set out what happens when a theory is applied in practice. A theory is simply the best explanation we have for understanding why some process takes place and predicting what the result will be.

Explanation: Anyone who describes something as “just a theory” does not understand what a theory is. Laws are arbitrary human rules. Theories are severely tested and re-tested explanations of why things happen in the real physical world and can be used to make predictions about outcomes.

Some would say that theories are about why something happens and laws (in science) describe what happens. But this simply makes a scientific ‘law’ a subset of a scientific theory, explaining how to make predictions.

Chloramphenicol binds in the active site of the large ribosomal subunit and inhibits peptidyl transferase activity in the 23s rr
valentina_108 [34]
This inhibition is restricted to bacterial translation because; the peptidyl transferase is an enzyme aminoacyltransferase as well as the primary enzymatic function of the ribosome, which forms peptide bonds between adjacent amino acids using tRNAs during the process of translation. Therefore, inhibition of this enzyme means that the process oof translation wont take place, hence proteins will not be formed and thus the bacteria will die.

vivado [14]

The<u> repressor </u>is a type of regulator protein that binds to a region of DNA in the promoter of a gene called the operator and prevents transcription from taking place.

In the field of science, a regulator protein can be described as a kind of protein that affects the transcription of a gene by having an influence on particular DNA sites. The rate of synthesis of various proteins is controlled by the regulator proteins.

A repressor is a kind of regulator protein that prevents the transcription of a particular gene. When the rate of a protein in the body has reached normal, the transcription of the protein needs to be stopped in order for more protein of that kind to be formed. The repressor binds itself to the operator region for the gene, hence stopping the transcription process until the protein is required again.
