Answer:
The group is called Enterobacteriaceae.
Explanation:
When lactose (or sucrose) is fermented, a large amount of acid is produced, which turns the phenol red indicator yellow both in bottom and in the slant (Escherichia, Klebsiella, Enterobacter).
If lactose is not fermented but the small amount of glucose is, the oxygen-deficient bottom will be yellow (remember that butt has comparatively more glucose than slant i.e. more media more glucose), but on the slant the acid produced (less acid produces in slant as media in slant is less) will be oxidized to carbon dioxide and water by the organism and the slant will be red (alkaline or neutral pH) (Shigella, Serratia, Salmonella, Proteus).
If no sugar is fermented, both the butt and the slant will be red (Pseudomonas. )
if H2S is produced, the black color of ferrous sulfide is seen (Salmonella, Proteus).
The process known as differentiation
Might be the second option, as active transport is the transport of proteins against the concentration gradient
<span>The temperature of the scrotum and testes is regulated by two muscles: the dartos and cremaster muscles. During cold weather these muscles contract the testes closer to the center of the body to maintain the correct temperature for sperm production; during hot weather they expand and sweat glands produce sweat. In the absence of sweat glands, the testes cannot be cooled properly, and sperm production may be affected.</span>
Molecules are moving because they have energy. As the liquid cools down, the amount of energy is reduced and the molecules start to move slower. When the water temperature reaches around 0°C, the molecules stick together and form a solid – ice. Even in this solid stage, the molecules are still moving – we just can’t see it.
