The spread of roots around a plant is usually greater than the depth of the roots.
valina [46]
The spread of roots around a plant is usually greater than the depth of the roots is a completely false statement. It totally depends on the type of plant in regards to the type of root it will have. Normally there are two kinds of roots and they are taproot and fibrous roots. In case of taproots the main root goes downwards and smaller roots branches out of it. In case of taproots, it is true that the spread of roots is smaller than the depth of the roots. In case of fibrous roots, the spread of roots is greater than that of the depth of the roots. A wig tree is an example of a plant having taproot. in the wig tree the root can go to a depth of around 120 meters.

For an organism to function properly all the physiological factors should be favorable. These physiological factors include water level, pH, temperature etc. To perform the basic function of the life, it is important to maintain the physiological parameter in a particular range.  

In case, these physiological parameters are not balanced, then the body of the organism does not perform well and causes illness.  

So, the first blank can be filled with temperature and the second blank can be filled with range.

I hope you meant, a cross between BbPp and BbPp, else for bbpp x bbpp, all the progeny will be bbpp.

We need to work out a Punnett square to determine the genotypes resulting from the cross between BbPp and BbPp. The dyhybrid cross results in 16 different genotypes, of which a few have the same phenotypes.

It can be seen that there are 4 different kinds of phenotypes present, in the ratio 9:3:3:1.
