enzymes are specific they will only fit with certain substrates explain why lactase can digest lactose but cannot digest other sugars like maltose and sucrose
Explanation:
your small your small intestines can't absorb either lactose or maltoseyou use different enzymes to digest the two sugars lactase break down lactose why an enzyme called sucrase-isomaltase breaks down maltose because enzyme are so specific with regard to function you can't break down maltose with lactose or vice versa
Lactase breaks down only lactose in food in our body can absorb it not maltose and sucrose as enzymes are specific in nature.
what are the properties of an enzyme ?Enzymes are protein which act as a catalysts and speed up the rate of biochemical reactions with out changing the structure of the final product.
Enzymes can control the speed and specificity of the chemical reaction, and the rate of biochemical reaction often influences enzymes and they can take place at a relatively low temperature; it lower the activation energy.
The enzyme activity pH specific, that is at a particular pH, each catalyst is most active for example at PH 2 for pepsin, pH 8.5 for trypsin, for example.
Both enzymes have active sites which can activate biochemical reactions. It is soluble in water, dilute glycerol, NaCl, and dilute alcohol.

what is the function of circuit breakers and fuses?
Answer:
Fuses and Circuit Breakers both serve the same purpose – which is to protect electrical circuits by preventing overloads that can cause fires. They both interrupt the flow of electricity, but in very different ways from each other. While a fuse is made of a piece of metal that melts when overheated, circuit breakers on the other hand, have internal switch mechanisms that can be tripped by an unsafe surge of electricity.
Fuses can be quicker for interrupting the flow of power, but when they melt they must be replaced; circuit breakers on the other hand just need to be reset. When comparing the two, we’ll take a look at some of the major advantages and disadvantages between fuses and circuit breakers to distinguish between them.

when the lac repressor protein binds to lactose, why does it fall off its binding site at the operator?
Answer:
English is not my native language so sry if there's any grammaticaly mistake
Explanation:
cuz it changes its shape and forme u got that?!
Lactose falls off its binding site at the operator because the allolactose binds to the repressor causing it to fall off the operator side.
What do you mean by Lac repressor?Lac repressor prevents the transcription of genes involved in lactose utilization in E. coli, such as lac genes.
When lactose becomes available a small amount of it is taken up by lactose permease and converted to allolactose by the enzyme beta-galactosidase.
Therefore, Lactose falls off its binding site at the operator because the allolactose binds to the repressor causing it to fall off the operator side.

Newly hatched birds that lack down and are nest-bound, unable to feed on their own, as with baby wrens or robins, are ALTRICIAL. These species include hummingbirds, swallows, passerine birds, woodpeckers, etc.
In altricial species, young individuals are underdeveloped at birth, thereby needing the help of parents to mature and develop into adult individuals.
Conversely, precocial species are species in which young individuals are mature and mobile from the moment of birth.
Most domestic species of birds (i.e., ducks, turkeys, chickens, etc) have a precocial type of development.

What happens when an action potential is produced with a signal that is stronger than threshold?
A)
weaker action potential generated
B)
no action potential generated
C)
action potential has same strength as threshold
D)
stronger action potential generated
Answer:
C) action potential has same strength as threshold
Explanation:
What happens when an action potential is produced with a signal that is stronger than threshold action potential has same strength as threshold
When an action potential is produced with a signal that is stronger than the threshold, the resulting action potential is typically stronger or more intense compared to a standard action potential. The answer is D) Stronger action potential generated.
The threshold is the minimum level of depolarization required to initiate an action potential in a neuron. If the signal surpasses the threshold, it means that the depolarization is greater than what is necessary to trigger the action potential.
When a stronger signal is received by the neuron, it results in a larger influx of ions (such as sodium) into the neuron, leading to a more pronounced depolarization of the cell membrane.
As a result, the action potential generated will have a higher amplitude or voltage compared to a regular action potential. Therefore, the answer is D) Stronger action potential generated.
