Answer:
orensically valuable DNA can be found on evidence that is decades old. However, several factors can affect the DNA left at a crime scene, including environmental factors (e.g., heat, sunlight, moisture, bacteria, and mold). Therefore, not all DNA evidence will result in a usable DNA profile.
Explanation:
Answer: (I hope you can understand this)
Type of operon: Trp
It’s a repressible operon
Lac
It’s an inducible operon.
Environment:
Trp
It’s deactivated when tryptophan is present in the environment.
Lac
It’s activated when lactose is present in the environment.
Repressor protein:
Trp
It’s activated by tryptophan.
Lac
It’s inactivated by lactose.
Transcription:
Trp
Tryptophan binds to the repressor protein, activating it.
Lac
Lactose binds to the repressor protein, deactivating it.
Explanation:
Plato
Ans:
This is through the movement of fluid particles from one place to another
Explanation:
when particles are heated they tend to absorb energy increasing there kinetic energy causing them to move hence there is transfer in energy from one place to another
It is also the reason for the up and down movement of fluids by heat transfer
Starch is broken down by enzymes or Nutrients are absorbed into the bloodstream.
