<span>It is important that the phospholipid bilayer is both hydrophobic in the surface and hydrophilic inside to control and manage the incoming organic compounds mainly water from exceeding the needed amount or destablizing the concentration established by the cells. </span>
<span>Hydrophilic is a characteristic of an object which is attracted to water or can synthesize with water. In contrast to hydrophobic like fats, oils and lipis which has a strong aversion and dislike to water molecules. </span>
Transmembrane proteins are found in the plasma membrane. Hydrophilicregions are embedded <span>within the membrane, and Hydrophobic regions project from both surfaces of the bilayer. </span><span>
Approximately 20-80% of the cell membrane is composed of lipids, the rest, is made up of protein. The lipid layer of the membrane gives it flexible and permeable characteristic. While the protein part assists in transport of molecules it needs to survive.<span>

Answer: Option C) Animal
The cell wall is tough, flexible and fairly rigid layer that surrounds some types of cells. It is located outside the cell membrane and provides cells with structural support and protection. All BUT ONE type of organism has cells with cell walls. That is an animal
Explanation:
One distinguishing feature of animal cells compared to other living cells is the absence of cell wall.
However, the animal cell possess a cell membrane, with which it regulates substances entering or leaving the cell, and also provide protection and mechanical support for the cell against foreign invaders such as pathogens.
The products of photosynthesis are glucose and oxygen.<span> Photosynthesis takes in carbon dioxide and water and combine them in the presence of energy from the sun to make food for the organism</span>
Answer:Temperature- Sensitive Mutation, C
Explanation:
AT 37°C ,<u> The organism transcribe a wild type--C.</u>
The type of mutation exhibited by the mutant bacterial strain is a Temperature- Sensitive Mutation. This is because at different temperatures, the organism transcribes differently ie transcribes at wild-type levels at 37°C and completely denatures and ceases to carry out transcription at 42°C .
The levels of organization in an organism may be broken down, from simplest to most complex, as:
1. Cell
2. Tissue
3. Organ
4. Organ system
5. Organism
A cell is the basic building of life and almost all cells in an organism's body are far more similar than they are different in both structure and function. Next are the tissues, which are groups of cells combined to carry out a special task. These tissues combine to form an organ, which a large part of the body that partakes in an important task, such as the heart pumping blood. Then is the organ system, which may contain multiple organs all working in conjunction to achieve a change in the organism's body. Finally, the organ systems combine and form the organism. The degree of complexity therefore increases.
