The enzyme that makes RNA knows where to start transcribing the DNA by knowing where to start transcribing at the promoter site. For example,<span> TATA Box in Eukaryotes. Hope this answers the question. Have a nice day. Feel free to ask more questions.</span>
The correct answer is option (a). Parent material
The soil horizon refers to distinct layers of the soils, which are parallel to one another, but have a different composition from the layer present above and below to it.
The soil horizon can be divided into four different layers. First one is organic layer, which is the topmost layer, below this layer second layer of topsoil is present. Below top soil, subsoil is present. Below subsoil, the bottom most horizon parent material is present.
Wernicke-korsakoff syndrome is associated with the decreased absorption and utilization of thiamin. The correct answer is c. thiamin..
The neurological condition Wernicke-Korsakoff syndrome is brought on by a lack of vitamin B1 (thiamin). There is no distinction between Korsakoff syndrome and Wernicke encephalopathy. The disease process is the same but at various stages. Both result from brain damage brought on by a deficiency in vitamin B1.
A prevalent deficiency in vitamin B1 is found in patients with alcohol use disorders. Additionally, it frequently affects persons whose bodies do not adequately absorb meals (malabsorption). This can occasionally happen after bariatric surgery or in conjunction with a chronic condition.
Following the disappearance of Wernicke encephalopathy symptoms, Korsakoff syndrome frequently appears. The thalamus and hypothalamus, two lower regions of the brain, are damaged as a result of Wernicke encephalopathy. Memory-related brain regions suffer permanent harm in people with Korsakoff syndrome.

Examples of allele types are HH. That is option 2.
<h3>Gene Allele </h3>
An allele in genetic studies is an alternative gene form that is located at a particular point of the chromosome. It is usually represented with capital and small letter of the same alphabet.
There are two types of a allele which include:
- Dominant allele: This is when the variation seen in a gene produces a noticeable phenotype. This is seen in the gene combination of HH.
- Recessive allele: This type of allele does not produce any visible noticeable phenotype. This is seen in hh.
Therefore, examples of allele types are HH
