1/4 recessive can be expected for the recessive trait of mono hybrids from the F2 generation.
Option D
<h3><u>
Explanation:</u></h3>
Mono hybrid cross is defined as the crossing between two plants considering the two different alleles of a particular character. It was 1st performed by Father of Genetics, Sir Gregor Mendel. The mono hybrid cross done by him considered the character tallness of garden pea plants, of which one was tall and other was short.
He crossed them to get all tall plants in 
Filial generation. Now as he self bred those plants, he got the tall and short plants in ratio of 3:1. Thus he proved that the recessive trait of mono hybrids is 
of the total population of F2 generation.
Answer:
the average annual rainfall.
Explanation:
It is defined as the annual amount of precipitation for a location over a year.
Fresh water community obtained its storage as precipitation from the atmosphere of rain, mist and snow..
The amount of rainfall of a community depends on the location.A typical rain forest receives average of 50,- 260 inches of rain per year.
The correct answer is C. This part is called the epithelium.
It is the muscular coat which consists of inner circular and outer longitudinal smooth muscle. Its main work is peristalsis.
To propel urine. The outer layer is the mucosa which has transitional epithelium that continuos with the lining of the renal pelvis and also the urinary bladder.
This layer of its work is to secrete mucus which protects and coats the surface of the cells.
The most common way to test
A hypothesis is to create an experiment a good experiment uses test subjects or creates conditions where you can see if your hypothesis seems to be true by evaluating a broad range of data
