Because as we evolve .....Some adaptation occurs according to the environment.....so the parts which are not right according to the environment and evolution become vestigial !!!
Answer:
Its important because if you repeat you'll get consistent results.
2. That means if a scientist gets different results it means they did something wrong in the experiment
Explanation:
<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:
E) Both Bacillus and Clostridium.
Explanation:
Bacterial endospores production is part of its survival mechanism. Bacteria produces these highly resistant spores that lies dormant in vegetative state, used during unfavourable and stressful environmental conditions. They are produced by gram positive bacteria such as Bacillus and Clostridium, and can lay dormant for years. Endospores are non-reproductive structures resistant to radiations, starvation and chemical disinfectants.
