Answer:
Option-4
Explanation:
Cow milk allergy or the cow milk protein allergy occurs when the allergy is caused by the proteins of the cow' milk when provided to the infant baby during the first 6 months.
The allergy is caused when the immune system of the infants consider the proteins of the cow milk as a foreign substance or antigens. These antigens activate the immune response which releases the chemicals and infant develop the symptoms of allergy.
Thus, option-4 is the correct answer.

Answer:
The small intestine is ___ to the liver. (Superior)
So, all the continents can combine into a supercontinent we call Pangea. We believe Pangea was formed a long time ago. Because of different world events (earthquakes, fissures,ice melting, the meteor that hit the dinosaurs, etc)this supercontinent split and the continents drifted away eventually forming the modern day topography we know today. We have evidence that Pangea was formed a long time ago because of similar species on different continents that would be too far away to share a common ancestor otherwise. (think about birds being on every continent, they can't have flown all the way across the Atlantic/Pacific)
Answer:
Non-coding DNA regions play important roles in regulating transcriptional activity by encoding different types of non-coding RNAs (ncRNAs), acting as scaffold attachment regions, acting as enhancer specific regions, etc.
Explanation:
Historically, it had been believed that non-coding DNA sequences were 'junk DNA' since they don't encode for proteins (beyond the sequences that are transcribed into functional non-coding RNAs, i.e., transfer RNA and ribosomal RNA). However, in the last years, it has been shown that non-coding DNA sequences play critical roles in regulating gene expression and genome function. For example, evolutionary conserved non-coding RNAs (ncRNAs) with regulatory roles on gene expression such as, for example, long non-coding RNAs (lncRNAs) and microRNAs (miRNAs) have been mapped in non-coding DNA sequences, thereby evidencing the functional significance of these regions. In consequence, the conservative nature of certain non-coding DNA sequences evidence that mutations in such regions may have significant deleterious effects, and thereby they could have a negative impact on the fitness of the individual.
