Answer: This is as a result of it covering more on the center part of the cell unlike when it is perpendicular.
Explanation: This is as a result of it covering more on the center part of the cell unlike when it is perpendicular. Cells in the primary visual cortex tends to responds to a particular direction of light. There are distinct inhibitory and excitatory regions and when the bar of light is moved over the cell you hear the firing rate (noise) which depends on the direction the light moves in. When the bar of light is set at an angle or perpendicular, the inhibitory receptive field is illuminated which slows the firing rate. when the bar of light is perpendicular, it leads to both the inhibitory and excitatory regions being illuminated which can sometimes result in their firing potentials canceling out each other, which can lead to no response in firing.

By studying the fossil record we can tell how long life has existed on Earth, and how different plants and animals are related to each other. Often we can work out how and where they lived, and use this information to find out about ancient environments.
<h2>Muscle contraction in cytoplasm </h2>
Explanation:
- Calcium stays in the sarcoplasmic reticulum until discharged by an improvement. Calcium at that point ties to troponin, causing the troponin to change shape and expel the tropomyosin from the coupling destinations. Cross-connect stick proceeds until the calcium particles and ATP are never again accessible.
- ATP is basic to get ready myosin for official and to "revive" the myosin.
- When the actin-restricting destinations are revealed, the high-vitality myosin head overcomes any issues, framing a cross-connect. When myosin ties to the actin, the Pi is discharged, and the myosin experiences a conformational change to a lower vitality state. As myosin consumes the vitality, it travels through the "power stroke," pulling the actin fiber toward the M-line.
