The rem dosage that most likely cause the following symptoms
mentioned above is the rem 120. It is because if this dosage has given to an
individual, the person may likely experience side effects of having to feel
nauseated, fatigue, vomiting and the white cell count is being reduced.
The genetic basis for lactose intolerance is a change in the nucleotide sequence outside of the lactase gene.
Lactose is normally hydrolyzed and broken down in the small intestine.
Lactose intolerance is due to mutations in the MCM6 gene, which regulates the expression of the lactase gene associated with the persistence of enzyme activity in adults.
The lactase enzyme is synthesized from the expression of the LCT gene.
The expression of the LCT gene is regulated by a protein complex (MCM), which is partly encoded by a specific sequence of the MCM6 gene located on chromosome 2q21.
A genetic alteration of this gene, specifically in position 13910, is responsible for the persistence or non-persistence of lactase in the adult.
The nucleotide sequence C / C (Cytosine / Cytosine) would be the one present in the non-persistence of lactase.
Therefore, we can conclude that lactose intolerance is due to a decrease or absence of the activity of the lactase enzyme and that it is due to a change in the nucleotide sequence that helps to control the expression of the LCT gene.

The correct answer for the question is B. Fossil.
Fossils are remnants, traces of animals or plants, from the past ages that have been preserved. Fossils may be classified as cast and mold fossil, insect preserved in amber, petrified wood, compression fossil of a fern and pyritized ammonite.
C. Perspiration and expiration.
Explanation – Insensible water loss is the type of loss which can't be felt like loss through perspiration or sweat and evaporation loss from the respiratory tract which is expiration. Sensible water loss is mainly urine which is released under our senses like see, feel and measure.
Insensible water loss is around 500-650ml/day according to some sources. There are certain factor that affects insensible water loss and are : temperature of the environment, humidity, altitude etc.
