Answer:

D) adhesion

Explanation:

Adhesion is a water property that allows water molecules to adhere to each other. This can occur thanks to its polarity. Water tends to attract and be attracted to other polar molecules. This attraction between water molecules and other polar molecules is called adhesion. When the slope occurs the water surface becomes curved, as shown in the figure.

Water molecules do not bind with nonpolar molecules, ie there is no adhesion. Therefore it is not evenly distributed on a waxed surface, and forms separate droplets on them, as the wax is nonpolar.

Andida albicans is part of our normal oral flora. Under certain conditions, it can overgrow, leading to oral thrush. Typically,
LekaFEV [45]

Answer:

Opportunistic, endogenous pathogen

Explanation:

Opportunistic infection is an infection that is caused by the microbes that are otherwise the component of one's own normal microbiota.  Under particular conditions, the microbes become pathogenic and cause infection. The pathogen-derived from one's own microbiota is called endogenous pathogen.

According to the given information, <em>Candida albicans </em>is a part of the microflora of mouth but becomes pathogenic under certain conditions. In healthy individuals, they do not produce disease as their overgrowth is suppressed by other microbiota and other host resistance mechanisms. The infection occurs only in those individuals with predisposing factors such as weakened immune system or after consumption of antibacterial medications that disturb the normal microbiota and immune competency. This makes it an opportunistic, endogenous pathogen.

Regulatory and basal transcription factors regulate transcription by binding to the promoter.A) True B) False
Licemer1 [7]

Answer:

False

Explanation:

In eukaryotes apart from RNA polymerase, the transcription of genes requires many different proteins called transcription factors. These transcription factors are important to initiate and regulate transcription.

There are two types of transcription factors regulatory and basal transcription factors. Basal transcription factors regulate transcription by binding to a gene promoter and regulatory transcription factor regulates transcription by binding to some regulatory sequences for example enhancers and silencers.  

Therefore only basal transcription factor binds to the promoter for regulating transcription. Therefore the statement is false.
