Answer:
The correct option is : c. travels through the conjunctiva
Explanation:
Loa loa worm is a roundworm that is responsible for causing the eye and skin disease called Loa loa filariasis. This worm is commonly known as the eye worm, as it is localized in the conjunctiva of the eye.
Loa loa does not normally affect the vision of an individual but when the worm moves across the bridge of nose or around the eyeball, it can cause severe pain.
Answer:
Option (A) and (C).
Explanation:
Gene regulatory mechanism are important for the regulation of the transcription and proper expression of genes. Different regulatory mechanisms are present in prokaryotes and eukaryotes.
The prokaryotes do not require the multiple general transcription factors where as the eukaryotes have different transcription factors like TFIID, TFIIH and TFIIA. The DNA is packed around the histone protein that form chromatin in eukaryotes. The chromatin packaging includes methylation, ribosylation with the help of enhancers and silencors. The chromatin is absent in case of prokaryotes.
Thus, the correct answer is Option (A) and (C).
Answer:
hydrogen and helium couldn't form until the universe had cooled enough to allow their nuclei to capture electrons, about 380,000 years after the Big Bang. Within about 3 minutes after the Big Bang, conditions cooled enough for these protons and neutrons to form hydrogen nuclei.
Explanation:
Biologists who work in the fields of genomics and molecular biology study DNA genome content and analyze genetics on a molecular level. They do it to map DNA and use it to prevent diseases or anything similar.
