Answer:
It's visual
Explanation:
That's the short answer it's because it visual. A pedigree has squares, circles, half colored squares and half colored circles and lines drawn to show the offspring or marriage. To me, it's like looking at a family tree except it's genetics! That's one way on how it simplifies the analysis of inheritance. Just a note to remind you about pedigrees. Squares are males and circles are female. If the box or circle is half colored with black, they are a carrier for a genetic disease (it depends on what their family has had like diabetes or sickle cell disease).
Answer:
Most of us have some familiarity with everyday magnetic objects and recognize that there can be forces between them. We understand that magnets have two poles and that depending on the orientation of two magnets there can be attraction (opposite poles) or repulsion (similar poles). We recognize that there is some region extending around a magnet where this happens. The magnetic field describes this region.
There are two different ways that a magnetic field is typically illustrated:
The magnetic field is described mathematically as a vector field. This vector field can be plotted directly as a set of many vectors drawn on a grid. Each vector points in the direction that a compass would point and has length dependent on the strength of the magnetic force. Arranging many small compasses in a grid pattern and placing the grid in a magnetic field illustrates this technique. The only difference here is that a compass doesn't indicate the strength of a field.

Global warming causes danger to human health and well-being, as well as to animals and plants. As global warming is mainly caused by anthropogenic activities, it was considered that emission of the so-called greenhouse gases should be reduced and in some cases even prohibited. Plants are more easily exposed to biological damage than any other living organisms.

So, the correct option is 'The causative HIV retrovirus reduces the number of T-helper lymphocytes'.
This describes erosion due to the mud sliding downward.
