A human has a total of 46 chromosomes (23 from daddy and 23 from mommy). :)
A sperm cell has 23 chromosomes and an egg cell that has 23 chromosomes. 23 + 23 equals 46. Sometimes (due to mutations), a person
may have less chromosomes than they need. This may cause some problems like Turner syndrome(treatment can help aid the situation but, it can't be cured).
Hope this helps you :)
DNA double helix is made of 2 complementary DNA strands . These strands are held together by hydrogen bonding between the complementary bases on each strand.
Nucleotides are the building units of nucleic acids. Bases are components of the nucleotides.
Bases on one DNA strands pairs with bases on the complementary DNA strand through hydrogen bonds.
bases can pair with the complementary base.
Complementary base of thymine is adenine .
Therefore thymine pairs with adenine.

Answer:
30, 000 plaques.
Explanation:
Plaques may be defined as the clear zones or spots that indicates the lysis of the bacteriophages. These plaques are useful to count the number of progeny phages.
The formula used to calculate the phage is as follows;
Plaques progeny = [Number of plaques observe/(Dilution factor x Volume of diluted virus)]
Since, in the given question the dilution factor and volume is not given and it can be taken as unity.
Plaques progeny = 30, 000 / ( 1 x 1)
Plaques progeny = 30, 000.
Thus, the answer is 30, 000.
