Answer:
CHICKENPOX
Explanation:
Varicella-zoster virus (VZV) causes chickenpox and herpes zoster (shingles).
CHICKENPOX follows initial exposure to the virus.
After the chickenpox runs its course, the virus retreats to nerve tissues near the spinal cord and brain, where it hides out.
Reactivation of the dormant virus results in the characteristic painful dermatomal rash of HERPES ZOSTER, which is often followed by pain in the distribution of the rash (postherpetic neuralgia).
Reactivation can be due to:-
1) A weakened immune system, which can wake the virus up
2) Cancer, HIV, or another disease that lower your body’s immunity
3) Being 50 or older
4) Being under a lot of stress
5) Past physical trauma
6) Taking long-term steroids or other medications that can weaken your immune system.
Answer:
The level of compaction in Eukaryotes from naked DNA to the most compact is:
d. nucleosome, solenoid, looped chromatin (300-nm fiber), metaphase chromosome
Explanation:
As we know that the
- Diameter of DNA is 2 nm.
- Diameter of nucleosome is 11 nm.
- Diameter of solenoid is 30 nm.
- Diameter of looped chromation is 300 nm
- Diameter of meta-phase chromosome is 1400 nm
All of these facts depict that the the least compact is DNA and most compact is meta-phase chromosome.
Answer:
Nebula, infant, young, mid life, adult, red giant, Supernova.
This is more astronomy related than biology.
