Answer:
D. nucleus
Explanation:
this is were transcription happens
Chromatids are the daughter strands of a duplicated chromosome which are joined by a single centromere
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.
the difference between the birth rate nad the death rate is known as growth rate. the growth rate is expresse in percentage ex:the presentrate of india is 1.93% per annum . According to 2001 census, birth rate was 26.1 per thousand and death rate was 8.7 per thousand . thus growth rate was 19.3 or 1.93% per year . births and death continue to take place at all places around the world . the differnce between total birth and total birth and total deaths in a populations over a period of time decides whether the population growthof the place is positive or negative. if the birth rate is higher than the death rate in a country, it means that the population will register a growth on the other hand, birth rate less than death rate indicates a shrinking population

It's the same thing as saying, why can't I see a atom with my bare eye???
The trees and cities are just WAY too small and far away for us to see if we were in outer space.
