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).
Answer:
Pressure gradients, the rotation of the earth, and friction are three primary variables that influence the wind. Atmospheric pressure gradients are the ultimate source of wind. The wind blows from high-pressure zones to low-pressure areas.

Answer:
B. helping the seeds to be scattered in new areas to grow.
Explanation:
- The scattering of seeds away from the parent plant is termed as seed dispersal and there are several mechanisms by which seeds can be dispersed, some of the means include gravity, wind, water, animals, etc.
- Seeds that have spiky structures such as hooks or claws are usually dispersed by animals.
- These spiky structures help the seeds to attach to the animal's fur or a feather and also to the bags or clothes of humans and thus, the seeds get scattered to new places along with the animals as they rub the seeds off their body or they fall on their own.
- Thus, <em>the spiky structure of seeds benefits the plant by as it helps in the dispersal of seeds and the plant can thus, grow in new areas.</em>
Answer:
I need to know what the options are
Explanation:
The angle bisector theorem is commonly used when the angle bisectors and side lengths are known. It can be used in a calculation or in a proof. An immediate consequence of the theorem is that the angle bisector of the vertex angle of an isosceles triangle will also bisect the opposite side.
