No further information is available so the answer will include the common orders by which the experiment was performed.
Answer:
Mendel is known as the father of the genetics and works on the pea plant Pisum sativum to explain the genetic laws.
The pea plant was selected by the Mendel because pea plant has short life cycle and both pollination are possible in the pea plant.
The monohybrid cross explains the law of segregation and the concept of dominance in the plants.
The dihybrid cross explains the law of independent assortment to explain the segregation of the different alleles.
Answer:
B)Prophase,Metaphase,Anaphase,Telephase
Explanation:
Prophase:At this stage,the chromatin threads condense to form distinct chromosomes, long and thin at first,later become shorter and fatter. Nucleolus disappears, nuclear membrane disintegrates, series of spindle (protein) fibres are formed spanning the cell from end to end.
Metaphase:Here, Chromosomes migrate to the central plain of the cells and arrange themselves round the equator of the spindle, attached by centromeres to be 'spindle fibres' microtubule.
Chromatids of each chromosome move slightly apart at the centromere regions,the sister chromatids being oriented towards opposite poles
Anaphase: Chromatids belonging to each chromosome part company and move towards opposite poles of the spindle, probably by a pull from the spindle fibres attached to the centromere which shortens.
Telephase: Chromatids reach the polar ends of the spindle and become densely packed together. Cell divide into two. Spindle fibres break down, centrioles replicate. Nuclear membrane is re-formed. Nucleolus reappears. Chromosomes gradually uncoil and return to their original thread-like form i.e, Chromatin threads.
In the glomerulus, a tuft of capillaries in the renal cortex, blood is filtered through the porous capillary walls.

The glomerulus receives its blood supply (that need to be filtered) from an afferent arteriole of the renal arterial circulation and the glomerular capillaries exit into efferent arterioles. The glomerular filtration rate is a rate at which blood is filtered through all of the glomeruli.</span> </span>
Answer:
Two
Explanation:
In a dihybrid cross there are two traits and four alleles
