which of the following is a basic building block of galaxies?

a. stars

b. gas

c. dust

d. all of the above

Stars are the basic building blocks of galaxies.

Explanation:

Stars are the dense embedded structures formed in compact in clusters. They range from  a dozen to million of stars.These are he observational indicators  of the gas expulsion from clusters  which may occur even quicker or late than  a stellar crossing time scale or within. They are classified into two main groups: OCs and globular clusters

OCs: They are ranging from few tens of millions of years old.They are generally young objects. They are  less tightly bounded by the gravity. & less densely populated.

Globular Clusters: These are a tight compositions/ formation of old stars which are distributed roughly in the galactic halo spherically  i.e.around the galactic center. Around the galactic centers they are having a  high elliptical orbits.

interphase   is the cell cycle stage in which the cell acquires nutrients, creates and uses proteins and other molecules and starts the process of cell division by replicating the dna. it is the longest stage in the eukaryote cell cycle.

the following   can go wrong during interphase:   a base pair could be mismatched during the duplication process causing a mutation.   correct answer: c

explanation:

surface modification is a versatile tool and has been widely used in material science and engineering that has significantly facilitated the study and characterization of complex materials. at  matexcel, experienced experts in surface science can offer tailored efforts to meet the specific needs from our clients.
