Answer: premaxilla bone (or maxilla) and the maxillary beak (or rhinotheca).
Explanation:
The beak is composed of keratin, the same tough, insoluble protein found in fingernails, hoofs, antlers and horns. A bird's bill comprises two parts. The upper portion of a bird's bill is called the maxillary rostrum, which consists of the premaxilla bone (or maxilla) and the maxillary beak (or rhinotheca).
The process starts when DNA is wrapped around special protein molecules called histones<span>. The combined loop of DNA and protein is called a </span>nucleosome. Next the nucleosomes<span> are packaged into a thread, which is sometimes described as "beads on a string". The end result is a fiber known as </span>chromatin<span>.</span>

Explanation:
The plate were supposed to streak by D. radiodurans but unfortunately it was streaked by E.coli.
As there is no other petri plate available, this plate was exposed to the UV for the 30 minutes. The plate was not left uncovered and because of that the total E.coli could not die and another streak of D. radiodurans was done on the same plate.
As a result of incubation there will be growth of both of the organism in the petri dish.

Explanation:
In general, photosynthesis in cyanobacteria uses water as an electron donor and produces oxygen as a byproduct, though some may also use hydrogen sulfide a process which occurs among other photosynthetic bacteria such as the purple sulfur bacteria. Carbon dioxide is reduced to form carbohydrates via the Calvin cycle.
