D.) biofilm formation
Many species of bacteria use quorum sensing to coordinate gene expression according to the density of their local population. In similar fashion, some social insects use quorum sensing to determine where to nest.
In addition to its function in biological systems, quorum sensing has several useful applications for computing and robotics.
Two commoly exploited fungal species are Saccharomyces cerevisiae and <span>Streptococcus thermophilus.
</span>Saccharomyces cerevisiae is used mainly on bread industry. As yeast, these fungi are very active metabolically. They ferment the cereal's sugars producing CO2 taht makes the bread rise.
Streptococcus thermophilus are used for yogurts. These also ferment sugar, this time lactose (milk's sugar), creating acid lactic that confers to the yogurt its acid taste and gives it the more solid texture.
B. An Experiment, Mainly because a hypothesis is a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation. A prediction is a <span>prophecy, And an observation is something that isn't full proven but opinioned. Therefore leaving B. An Experiment The only logical answer above. </span>
<span>Different body conditions react to different medications in so many different ways. All similar patients do not have the same reactions to same medicine. For some it do not bring any change in the condition and for some it may give some extreme side effects. So it is necessary for a follow up with the physician for Melissa because he can gauge the effect of medicine to her problem and suggest something that needs to done in addition.</span>
