spongy bone is found in the bones of the skull, sternum, vertebrae, the pelvis, the lining of the marrow cavity and the epiphysis.
A vacuole
is responsible for temporary storage for water, waste products, food, and other cellular material.
Explanation:
Vacuoles are storage bubbles found in cells. They are found in each animal and plant cells however are a lot of larger in plant cells. Vacuoles may store food or any form of nutrients a cell may got to survive. they'll even store waste merchandise that the remainder of the cell is shielded from contamination.
Answer:
Something that can be tested, or rationalized.
Explanation:
You didn't give any statements to choose from, so I'll give you a rule of thumb. When finding a scientific statement, make sure it's something like "The tide is higher at noon than it was at 3 am." and not "Your dog is itchy, so that means a bad storm will arrive."
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.
