Answer:
Option A , Genome
Explanation:
Microarrays that contains array of single stranded DNA are used to study thousands of gene expression for all the genes of a genome and are usually termed as DNA miscroarrays. These microarrays being single stranded allows attachment of complementary DNA strand to bind to their surface. The mRNA from the cell is extracted and converted into cDNA which is further used for DNA cloning.
Hence, option A is correct
 
        
             
        
        
        
Answer:
Explanation:
DescriptionA biological system is a complex network of biologically relevant entities. Biological organization spans several scales and are determined based different structures depending on what the system is. Examples of biological systems at the macro scale are populations of organisms.

Answer:
The correct answer is option D) six dominant and two recessive.
Explanation:
The most common genetic inheritance pattern involves cross between heterozygous recessive parents which means it has one allele of each character in every parent (suppose Tt).
Cross between these parents provide these offspring; TT, Tt, Tt, and tt which exhibit 3:1 ration which can also be mention as 6:2 which means 6 out of the 8 has dominant (homozygous or heterozygous) and 2 out of 8 offsprings are recessive alleles.
Thus, the correct answer is option D) six dominant and two recessive.
 
        
             
        
        
        
Answer: No 
Explanation:
The electrician just cannot replace any piece of wire to fuse because the ceramic that is used in case of fuse has a wire attached in it.
This wire is of  low resistance so that when there is higher voltage the wire just cannot tolerate the high voltage and wire breaks down.
Any wire just cannot be replace by the fuse because the there are some calculations which has to be made.
The wire if used should be of low resistance and more properties then only it is eligible to be replaced by fuse.
