Answer:
0%
Explanation:
This question involves a gene coding for height in pea plants. The allele for tallness (T) is dominant over the allele for shortness (t). This means that allele T will be expressed over allele t in an heterozygous state. 
A purebred tall plant will possess genotype: TT while a heterozygous tall plant will possess genotype: Tt. The two parents will produce the following gametes:
TT- T and T
Tt- T and t
Using these gametes in a punnet square (see attached image), the following offsprings with genotypes: TT and Tt in a ratio 1:1 will be produced. 
TT offsprings are purebreed tall while Tt offsprings are heterozygous tall. Hence, based on the question, no offsprings of this cross will possess the recessive genotype (tt). This means that 0% of the offsprings of this cross will be short.
 
        
             
        
        
        
Answer:
A
Explanation:
Mendel didn't care about growing the best pea plants or producing more peas. The remaining an.swers are to do with traits which could be confusing. He had green and yellow pea plants to see what their offspring's traits would be

Multi cellular organisms are made up of billions of cells each specialized to a unique role and these cells are organized into structural and functional units such as tissues and organs.
For each cell and organ to function optimally, it requires oxygen and nutrients and needs carbon dioxide and  metabolic waste taken away  in a  continuous, never ending  process.
<span>A mechanism  is needed to accomplish the important function of transporting the relevant materials to and from the cell. The circulatory system fits this  bill splendidly. It is a specialized organ system which allows blood  and lymph to flow through the entire body carrying nutrients such as glucose, amino acids and electrolytes as well as oxygen to each cell, at the same time carting away carbon dioxide and all sorts of metabolic waste over to excretory organs  to be expelled from the body.
