Answer:
The correct aswer is crystal size.
Explanation:
Cooling rate affects to the size of the crystal formed by cooling a molten material. A fast cooling produces small crystals whereas slow cooling produces large crystals. At a slow cooling rate, crystals have more time to grow and therefore they are larger than those are formed at a fast cooling rate.
The buoyant force is equal to the weight of the fluid displaced by an object when the object is submerged into a liquid. Gravitational force is the force of gravity, and friction is the force created when two objects rub up against one another when at least one of the objects is in motion.
Answer: Meteorology
Explanation:
Meteorology could be described as the study of the atmosphere which basis it's emphasis on weather processing and forecasting. Meteorology draws a combination or conclusion between the rains coming down on the earth surface which is being predicted based on how the cloud appears. This brand extends from the atmosphere to the surface of the ocean.
Answer:
B -the absence of the inducer, but not in its presence
Explanation:
In positive repressible regulalor mechanisms transcription of the structural gene(s) occurs in the absence of the inducer because proteins are normally bound to the pertinent DNA segment. when an inhibitor is bound by the inducer, it is prevented from binding the DNA. which will the stops the activation and transcription of the structural genes.
Example of positive repressible regulator is Activator .
Regulating the rate of transcription is a mechanism of gene regulation leading to the productionn of more than one protein product from a single gene.
