Restriction enzymes recognize specific nucleotidic sequences. The molecule with no recognition site will not be digested. Individual S2 probably had molecules with the recognition site and others with a different sequence.
--------------------------
A restriction enzyme is a degradative polymer that recognizes and cuts up specific nucleotide sequences in DNA.
Restriction enzymes can produce cohesive cuts or blunt (abrupt) cuts, depending on the recognition sites.
The frequency in which the restriction enzyme will produce the cuts depends on the recognition sequences and the number of bases that compose them.
So restriction enzymes cut DNI molecules into different short sequences of varying lengths.
These pieces are called minisatellites and exhibit the existing variation from one person to the next.
These short sequences can be separated by using gel electrophoresis and will express a pattern of differentiation.
When the nucleotidic sequence of the DNA molecule does not include the recognition site, the enzyme will not cut this fragment. The enzyme does not digest this molecule.
Since the negative control does not have a recognition site, it is not digested by the enzyme.
The positive control is digested, meaning that these molecules carry the recognition site.
Probably DNA molecules from individual S1 do not have the recognition site either.
The enzyme recognizes the sequence in DNA from individual S3 and cuts it into two fragments.
The lane of Individual S2 includes both options: digested and not digested DNA. This means that the sample taken from this individual included DNA
⇒ carrying the sequence, and
⇒ not carrying the recognition sequence.
So enzymes digest molecules carrying the recognition sequence, and the other ones remain undigested.
Probably, individuals S1 and S3 are h0m0zyg0us, while individual S2 is heter0zyg0us.

how do identify veins in our body
Answer:
Veins are blood vessels in humans, and most other animals that carry blood towards the heart. Most veins carry deoxygenated blood from the tissues back to the heart; exceptions are the pulmonary and umbilical veins, both of which carry oxygenated blood to the heart. In contrast to veins, arteries carry blood away from the heart.
Explanation:
A running back is running down the field and two people on the opposing team run towards him. One person is running east with a force of 250 N. The other person is running west with 250 N of force . They all collide at the same time. Show the forces affecting the running back.
Are the forces balanced or unbalanced?
Net force = ?
Given our understanding of the laws of physics, we can confirm that the Net force affecting the running back (ignoring gravity and its complementary force) is that of 500N and balanced.
In physics, we can say that the net forces being applied to an object are balanced when the forces are
Equal in sizeApplied in opposite directionsApplied at the same time.The question states that the running back collides with two members of the opposing team at the same time. This, coupled with the fact that the opposing team members are described to arrive on exactly opposite sides, we can say that the forces being applied to the running back are indeed balanced.
Furthermore, since the forces are 250N in size each, we can confirm that the net force applied to the running back is 500N. To this, we would normally add the force of gravity, however, in order to do this, we would need the weight of the running back, that is, data that is not provided.

As a result of higher osmotic gradient outside, ____________ moves out of the thin descending limb of Loop of Henle
Answer:
is it water?
Explanation:
As a result of higher osmotic gradient outside, water moves out of the thin descending limb of Loop of Henle.
What is osmotic potential?Osmotic potential is a component of water potential whose magnitude depends on the amount of solutes present in the solution, with osmotic pressure defined as the pressure necessary to prevent osmosis from occurring.
The loop of Henle (or nephr), in anatomy, is the segment of the nephron that comes just after the proximal convoluted tubule, being a U-shaped tubular structure, with a thick and a thin portion. That can be done with the osmotic potential.

Does “survival of the fittest apply to domesticated animals? Why or why not? *
Answer:
Yes.
Explanation:
This survival of the fittest is instinct helps domestic animals live. Just because an animal is domesticated, does not mean that instincts go away. Those instincts like hunting may get suppressed, but not taking away.
Answer:
Survival of the fittest does not apply to domesticated animals. This is because these animals don't live in the wild so they don't have to run after things and kill them. Their food comes out of a tin and is provided by human beings. They don't have any predators so their lives are seldom at risk. Thus, they don't need to be fitter or more powerful than other animals in any way.
Lets take the example of pet dogs. We keep them for our support or simply because we enjoy their company. We provide them with food, shelter etc. and protect them. Since, we basically do everything for them; they need not evolve into a stronger, more powerful species.
However, in the case of stray dogs, they have to fight for their survival. They have to fight with other dogs for food and shelter. Hence, survival of the fittest will apply here as the strongest dog gets to eat.

B. What are two ways Smoky can increase his speed? (Use Newton's 2nd Law to help you)
C. What is an example of an action and reaction at work in this picture? (Use Newton's 3rd Law to help you)
The mouse exerts a force on the ground and the ground exerts an equal and opposite reaction force on the mouse.
At point B, Alberto's distance covered increases with time, equal distance is covered in equal time interval. The speed increases uniformly. At the point C to D, the distance covered with time remains the same. At the point D, equal distance is no longer covered in equal time intervals.
According to the law of inertia, an object will remain at rest or in a state of uniform motion unless it is acted upon by an unbalanced force. This means that smokey mouse will continue moving uniformly unless a force acts on it.
From Newton's second law; F = ma and a = F/m. F = force , m= mass, a = acceleration. This implies that smokey mouse can increase its speed by;
Increasing the force acting on the mouseDecreasing the mass of the mouseAction and reaction is encountered as the mouse is walking. The mouse exerts a force on the ground and the ground exerts an equal and opposite reaction force on the mouse.

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.
