A fossil will most likely be found in a sedimentary rock.
It is likely that the light blue colonies have a mutation in GENE I (lacI gene). LacI (lactose inhibitor) is a DNA-binding factor that represses transcription of the lac operon.
The lacI gene (regulatory gene for lac operon) is a gene located upstream of the three genes of the lac operon (i.e., lacZ, lacY, and lacA), which are transcribed as a unit.
The inducer of the lac operon is allolactose. When lactose is present, a small amount of this molecule is converted to allolactose.
The lac repressor, which is encoded by the lacI gene, binds to the operator upstream of the lac operon, thereby preventing its transcription unless the inducer is present.
Finally, the lacZ gene produces an enzyme called β-galactosidase, while X-gal is a blue-colored product precipitated when a bacterial colony expresses a functional β-galactosidase.

Answer:
Do you mean the definition?
I think it is "population density". Population density is the number of individuals per unit area or volume.
Explanation:
Retine is something seen in animal cells that restricts growth and cell division.
<h3>What is retina for eyes?</h3>
The retina contains millions of light-sensitive cells (rods and cones) and other nerve cells that accept and organize visual information. Your retina sends this information to your brain via your optic nerve, enabling you to see.
<h3>What causes retina injury?</h3>
Retinal damage is one of most common ailments of the eyes. The most common causes of retina injury are those related to old age, light damage or trauma. Retinal conditions can damage this vital tissue. They can affect your vision, and some can be severe enough to cause blindness

B - sponges.
Sponges can regenerate but can’t reproduce through regeneration
