I need help with this work sheet please
Answer: 1. I would choose BbEe(black) and bbEe(chocolate) because when they crossover each other, one of the possibilities is bbEe which would be a yellow dog.
2. Yes, because when you cross the two, you will get at least 1 of each color as a result.
3. BE, Be, bE, be
4. When crossing BBee and bbee, the result was Bbee which is also a yellow dog.
5. I would not want BbEe.
6. When you cross bbEe and BBEE, the probability for a black dog would be 16/16. The other colors would be 0/16.

When a molecule other than substrate binds to the active site of an enzyme and
slows its activity
Definition
Answer:
Competitive inhibition
Explanation:
Competitive inhibition is a type of enzyme inhibition where one molecule inhibits the effect of another molecule (called the substrate) by competing with it for binding at the active site of the target enzyme, thereby preventing the substrate from binding. The active site refers to the specific region of an enzyme that binds with a particular substrate. This mechanism is well-known in pharmaceutics, where specific drugs are designed to show structural resemblance to a particular substrate, preventing its normal function.

Please help... This is middle school stuff. It'll be easy for you.
Answer:
Volcano eruptions-when one plate is submerged below another, it melts and goes back to the surface as magma and creates a volcano
Earthquakes- when 2 plates slide against or hit each other
Seafloor spreading- where divergent plates move away from esch other, magma goes up to the surface and solidifies
Mountain formation- When two convergent continental plates hit each other. Continental plates are light so instead of submerging, they both rise higher to the surface and creates high land(mountains)
