What else can I help you with?
True or False Low Km means that an enzyme binds very loosely to a substrate andd consequently results in a high velocity compared to an enzyme with a high Km?
False. Low Km actually indicates a strong binding of the enzyme to the substrate, resulting in a high affinity and low velocity at low substrate concentrations. High Km means a weak binding of the enzyme to the substrate and requires higher substrate concentrations for the enzyme to achieve maximum velocity.
Do negative feedback mechanisms decrease or end the original stimulus?
Negative feedback mechanisms work to decrease or counteract the original stimulus, rather than completely ending it. The goal is to bring the system back to its set point or normal level by regulating the stimulus within a certain range.
Why do you use a negative control in PCR?
A negative control is used in PCR to ensure that there is no contamination in the reaction, which could lead to false positive results. It contains all the PCR components except the template DNA, so any amplification detected in the negative control would indicate contamination.
Why is timing so critical when decolourizing in Gram staining?
Timing is critical when decolorizing in Gram staining because if the decolorizer is left on for too long, it can wash away the crystal violet stain from Gram-positive cells, leading to a false negative result. Conversely, if the decolorizer is not left on long enough, the crystal violet stain may not be fully removed from Gram-negative cells, leading to a false positive result. Timing ensures accurate differentiation between Gram-positive and Gram-negative bacteria.
What is a negative consequence in using DNA technology in forensics?
A negative consequence of using DNA technology in forensics is the potential for misinterpretation or mishandling of evidence, leading to false incrimination or exoneration of individuals. Additionally, concerns about privacy and the potential for misuse of genetic information are valid considerations.
True or false a negative slope on the velocity vs. time graph indicates that the object is not accelerating?
False. A negative slope on a velocity vs. time graph indicates that the object is decelerating, not that it is not accelerating. Acceleration and deceleration are both forms of acceleration, but in opposite directions.
A negative slope on the velocity vs time graph indicates that the object is not accelerating true or false?
False. A negative slope on the velocity vs time graph indicates that the object is decelerating or slowing down, but it is still accelerating in the opposite direction.
A negative slope on the velocity vs time graph indicates that the object is not accelerating?
false
When an IDS fails to detect an attack this is considered to be a false positive true or false?
False; it's a False Negative
The continental slope drops downward dramatically and is considered a boundary line true or false?
TRUE
Is the force of gravity on a projectile in motion is considered positive.?
false
Are negative numbers considered true or false in c?
zero= false, non-zero=true
Are negative number considered true or false in C programming?
zero= false, non-zero=true
A negative slope on the velocity vs. time graph indicates that the object is not moving.?
False. It means it is slowing Down!
True or false a velocity of 50 rad per min is a linear velocity?
False.
A negative slope on the velocity vs. time graph indicates that the object is not moving?
False. It means it is slowing Down!
Is Acceleration is the magnitude of average velocity true or false?
False
