The independent variable should stay constant because each group should be completely different to do an experiment while it is being conducted.
What are variables?
The variables are defined as any characteristics, number or quantity which can be measured . They can also be called as a data item . They are called as variables because they can vary and can have variety of values.
There are three types of variables 1) manipulated variable where in a condition is specified, 2) responding variable which is dependent on manipulated variable 3)controlled variables which does not change
Example of manipulated variables are number of hours spent by a student studying , that of responding variable is result of a student and temperature is an example of controlled variable.

Question 2
Answer the question below about Smokey The Mouse.
A. Use inertia to explain how a balanced force will affect his motion. (Newton's 1st Law)
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.

suggest a reason why termites have no eyes
Answer:
the pests have antennae covered with moisture-sensing receptors
Explanation:
Answer:
Many species of termites need to find areas of vegetation with plenty of moisture to survive. To get around their lack of vision, the pests have antennae covered with moisture-sensing receptors.They also have eyes but their wings do not develop further. These develop into the neotenics (see below), which are one of the reproductive types and have the ability to produce eggs in the colony in certain situations

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.

which antioxidant plays an important role in cell differentiation, the process by which stem cells mature into highly specialized cells?
Vitamin A is regarded as the antioxidant that plays an important role in cell
differentiation.
Cell differentiation is the process by which cells become specialized by
changing from one form to another to achieve a common structure and
function.
Vitamin A has a strong metabolite known as retinoic acid which is involved
in this process which supports it and also helps to eliminate the free radicals
which may be present.

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.
