Q:

Point out the error, if any, in the following program.

#include "stdio.h"

main()

{

      unsigned char;

       FILE *fp;

       fp = fopen ("trail", "r");

       while (( ch = getc (fp)) ! = EOF)

               printf ("%c", ch);

       fclose (fp);

}  

Answer

EOF has been defined as #define EOF -1 n the file "stdio.h" and an unsigned char ranges from 0 to 255 hence when EOF is read from the file it cannot be accommodated in ch. Solution is to declare ch as an int.

Q:

How many chromosomes are in a human gamete?

A) 23 B) 46
C) 92 D) 102
 
Answer & Explanation Answer: A) 23

Explanation:

23 chromosomes are in a human gamete.

Human somatic cells have 46 chromosomes(23 pairs) but a gamete(germ cell) gets half the amount, i.e. 23 chromosomes, (one from each pair). There will be half the number of chromosomes an organism has in its somatic cells (all other body cells except gametes).

 

For example in humans, the somatic cells contain 46 chromosomes which are the diploid number (2n) and each sperm and egg has 23 chromosomes where one of them is the sex chromosome.
