Which system controls the rate at which you blink?
Iris muscles! The circular muscles contract to reduce the size of the pupil in bright light. Radial muscle fibres contract to widen the pupil in places of low light intensity. The contraction and relaxation of circular and radial muscle fibres in the iris are antagonistic, and an example of cerebral reflex.
Which factor affects most in transpiration-humidity or light intensity?
Light intensity
How does light intensity affect the voltage?
Light intensity affects voltage because the higher the intensity of light, the more volts are produced. It works exactly the same way in the case of: the lower the light intensity the less volts that are produced.
How does the rate of photosynthesis respond to changes in light intensity?
It directly increases along with the growth in intensity of the light
Why does coherent light have a relatively constant intensity?
Coherence relates to the physics of waves. Specifically, it refers to a property that allows constant interference. Because interference varies the intensity of light, coherent light has a relatively stable intensity.
Do smooth muscle have alternating dark and and light bands on them?
Yes, smooth muscle has alternating dark and light bands known as the A and I bands, respectively.
What is the muscle that makes the pupil smaller in bright light?
Smooth Muscles.
The iris is composed primarily of two smooth muscle layers?
the radial fibers contract,enlarging the pupil and allowing more light to enter the eye
What do striations muscles look like?
Striations are light and dark bands on skeletal and caridac muscle fibers. Smooth muscle lacks striations

What is the light intensity in the arctic?
The light intensity is poop!
What part of the eye that controls the passage of the light into the eye?
Pupil controlled by iris which is in turn is controlled by cilliary muscle
What is the function of the diaphragm on a microscope?
It has different sized holes and is used to vary the intensity and size of the cone of light that is projected into the slide
Refer to your graph of productivity and light intensity At what light intensity do you expect there to be?
0% light and 25% light
Which factor affects most in transpiration-humidity or light intensity?
Light intensity
At what light intensity do you expect there to be no net productivity?
100% light intensity ?
What is the function of pupil in human eye?
. The pupil is an adjustable opening that controls the intensity of light permitted to strike the lens. The lens focuses light through the vitreous humor, a clear gel-like substance that fills the back of the eye and supports the retina
