Answer:
variable
Explanation:
Globular clusters is defined as collection of numerous star that revolve around the galaxy core. they are so bound to each other that they formed spherical shape. This boundness among the star is due to gravity. The main characteristics of globular cluster is that they contain high density of star at center.

Answer:
thymine
Explanation:
The nitrogen base found only in DNA is known as thymine which is also called 5-methyl uracil as thymine is a derivative of uracil.
Solution :
Energy of photon, E = 6.7 eV
E = 
joule
Kinetic energy, 
Kinetic energy at high speeds
r - 1 = 7130
r = 7130 + 1
r = 7131
![$v^2=C^2\left[1-\left(\frac{1}{7131}\right)^2\right]$](https://tex.z-dn.net/?f=%24v%5E2%3DC%5E2%5Cleft%5B1-%5Cleft%28%5Cfrac%7B1%7D%7B7131%7D%5Cright%29%5E2%5Cright%5D%24)
Δ = 1 - 0.99999999017
= 0.00000000933
Relative mass, 
kg
Scientists can tell this by looking at seismic waves released by earthquakes. ( if you need me to elaborate more ask)
