Explanation:
How do I make my soil drain better for plants?
Adding lots of organic matter such as compost, farm manure, or shredded leaves to clayey soil will allow it to drain more easily and hold the right amounts of water and air for better plant growth and increased biological activity.

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.
 
        
                    
             
        
        
        
Answer:
G-banding or Giemsa banding is a technique used to study the chromosomes by staining then at condensed stage. The visible karyotype can be used by this technique. The genetic diseases can be easily identified by this G banding technique.
The base composition of the genes (nucleotide) are stained by the dye known as Giemsa stain. The nitrogenous base adenine and thymine of the heterochromatic region of chromosome stained darkly in this technique. The darkly stained area is generally gene poor area.
