zysi [14]

The structure of the cell is very much linked with the functions of the cell.The cardiac muscle is made of myocardium which serves the body by providing the blood, nutrients and oxygen.The cardiac muscles appears stripped when seen under microscope.

The skin consists of the tissues and cells which are close enough to create a boundary which does not allows the entry  of materials and pathogens inside the body.

8. Two rabbits are bred together. One is heterozygous for agouti coat
dusya [7]

Answer:

- Parental cross = Cch  x chch  

- F1 = 1/2 Cch (agouti coat); 1/2 chch (albino coat) >> 1:1 phenotypic ratio

Punnett  square:  

          ch         ch

C       Cch       Cch

ch    chch      chch

 

Explanation:

A heterozygous individual is an individual who has two different gene variants (i.e., alleles) at a particular <em>locus</em>. In this case, individuals having the "agouti coat" trait are heterozygous carrying both 'C' and 'ch' alleles. On the other hand, a homo-zygous individual has the same allele at a given <em>locus</em> (here, the 'chch' genotype associated with the albino phenotype). Therefore, as observed in the Punnett Square above, when a heterozygous parent is crossed with a homo-zygous recessive parent for a single gene, alleles segregate in the gametes of both parents so an expected 1:1 phenotypic ratio will be observed.
