Answer:
Transcription factors
Explanation:
They are part of the cell's core transcription toolkit, needed for the transcription of any gene. RNA polymerase binds to a promoter with help from a set of proteins called general transcription factors.
Taxonomy is the branch of science that concerns labeling and classifying living things into more manageable groups. This helps scientists better understand certain species and their connections to other species.
Answer: color, cleavage, clarity, durability, and crystal system
Explanation: color - distinctly green color that ranges between bluish green and slightly yellowish green.
cleavage - one direction of imperfect cleavage
clarity - almost every natural emerald has eye-visible characteristics that can be inclusions, surface-reaching fractures, or healed fractures. Treatments to fill the fractures with oils, waxes, polymers, flux and other materials to reduce their visibility has been common practice for hundreds of years.
durability - emerald is very hard, but almost all specimens have inclusions and surface-reaching fractures that compromise their durability
crystal system - hexagonal
Answer:
how many pores or holes in a rock let more things in depending on how many pores/holes it has. think of it like skin. the bigger your pores the more dirt seeps through
