"Describe how increasing the stimulus frequency affected the force developed by the isolated whole skeletal muscle in this activ

Sonja [21]2 years ago

Answer is seen below

Explanation: Stimulus frequency refers to the rate that stimulating voltage pulses are applied to an isolated whole skeletal muscle.

When a stimulus frequency is at the lowest ( let's say 50stimuli/second) the force will be at its lowest level out of all of the experiments. As the stimulus frequency was increased to 130 stimuli/second the force increased slightly but fused tetanus( tetanus refers to a sustained muscle tension due to very frequent stimuli) developed at the higher frequency. When the stimulus frequency was increased to the amounts of 146-150 stimuli/second, a maximum tetanic tension occurred, where no further increases in force occur from additional stimulus frequency.

By increasing the stimulus frequency if it resulted in increasing the muscle tension generated by each successive force and it had limit that was eventually reached. Then the results equaled to your prediction.

Which kind of pigment reflects two primary light colors and absorbs one?1) primary pigment2) secondary pigment3) complementary p
weqwewe [10]

The primary colors of light are red, blue and green.

There are the pigments like yellow, magenta and cyan that are the mixture of two primary colors.

For example, magenta is a mixture of red and blue color. Thus, it reflects the red and blue color. Also, magneta absorbs the green color.

These type of colors that reflects two primary colors and absorb one color are known as secondary pigments.

Hence, 2nd option is the correct answer.

Observe the two scenarios involving electrically charged objects. Predict what will happen when you bring the objects close toge
Margarita [4]

Answer:

When one object is rubbed against another, static electricity can be created. This is because the rubbing creates a negative charge that is carried by electrons. The electrons can build up to produce static electricity. For example, when you shuffle your feet across a carpet, you are creating many surface contacts between your feet and the carpet, allowing electrons to transfer to you, thereby building up a static charge on your skin. When you touch another person or an object, you can suddenly discharge the static as an electrical shock.

Explanation:

Similarly, when you rub a balloon on your head it causes opposite static charges to build up both on your hair and the balloon. Consequently, when you pull the balloon slowly away from your head, you can see these two opposite static charges attracting one another and making your hair stand up.

How does inertia affect a person who is not wearing a seatbelt during a collision?
Rainbow [258]
An object in motion will stay in motion, therefore the person will still be going the same speed as the car was going before the collision

A moose runs through the woods and covers 825 m North in 118 s. What is the average velocity of the moose?
weqwewe [10]
  • Total displacement=825m
  • Total Time=118s

Average Velocity=Total Displacement/Total Time

\\ \sf\longmapsto Average\: Velocity=\dfrac{825}{118}

\\ \sf\longmapsto Average\:Velocity\approx 8m/s
