Klinglers iron agar medium is used to find the enterobacteria which can ferment glucose , lactose and hydrogen Sulphide . They are H₂S producing bacteria .
This media have phenol red as an indicator. When the glucose is fermented to acid , the production of acid turn the indicator from red to yellow, but it is then reoxidised and turns red again . When lactose is fermented it produce large amount of acid , and turn indicator yellow . Hence the slant will become yellow.And combination of ferrous sulphate and sodium thiosulphate helps in detection of H₂S which produce black color at the butt .

A test cross can be used to determine the genotype of the parent (whether it is homozygous or heterozygous for a specific trait).
AA x aa = all Aa offspring, dominant phenotype.
<span>Aa x aa = 1/2 Aa dominant and 1/2 aa recessive

The sickle form of the hemoglobin gene is created when an adenine nucleotide is changed to a thymine. ... That single amino acid replacement in the -globin protein alters the shape and the chemistry of the hemoglobin molecule, causing it to polymerize and distort the red blood cell into the sickle shape.

During transcription, RNA molecules re produced, mRNA specifically. Transcription in protein synthesis is when the mRNA is created using the template of DNA. It is the process of transcribing DNA to mRNA which is catalyzed by RNA polymerase. Transcription encompasses manufacturing, splicing, and adding of caps and tales of the mRNA. All of these happen in the nucleus of the cell. Replication, transcription, and translation are three different terms. Replication means duplication of DNA. Transcription is the multiplication or duplication of genetic information into mRNA and translation is protein production through activities of ribosome.
The animal was most likely a carnivore, or omnivore, it ate meat, or meat and plants, the sharp teeth are used for tearing through the flesh and meat of smaller animals, and they could’ve been used to break down and grind up plants.
