Answer:
The time it takes for light from stars to reach us is the distance to the star divided by this speed
Explanation:
light travels at 300,000 kilometers per second or 186,000 per second. The nearest star to us is the sun and it takes about 8.3 minutes for its light to reach us here on Earth
Answer:
A
Explanation:
because bacteria grows small till it dies
Answer:
atom formation → big bang → star and galaxy formation → expansion and cooling → continuation of expansion and cooling
Explanation:
Hope its help
Answer:
b. orientation dependent
e. located upstream of the gene it controls
Explanation:
Promoter sequences:
These are the sequences present within the DNA on which RNA polymerase binds and start transcription of a gene. These sequences are present directly upstream of transcription initiation site at the 5' end.
Prokaryotes and Eukaryotes both have specific promoter location site which is fixed. So first (a) and Last (f) options of this question are wrong.
This sequence have specific orientation Like TATA box so these are orientation dependent.
These sequences are present directly upstream of transcription initiation site at the 5' end.
