Answer:
380
Explanation:
The mentioned double-stranded DNA has 80 thymine nucleotides. This means that this DNA duplex has a total of 80 adenine bases. Since thymine pairs with adenine, the number of thymine and adenine is equal in a double-stranded DNA. Similarly, the presence of a total of 110 guanine nucleotides in the DNA indicates the fact that it has a total of 110 cytosine nucleotides. So, total number of nucleotides in this DNA double helix would be= 80 A + 80 T + 110 G + 110 C= 80 + 80 + 110 + 110 = 380.
Answer: Fungi are microscopic heterotrophic living organisms that grow as long threads called hyphae. In terms of their function, they can be divided into-
Parasitic fungus that obtains nutrients from living host while harming it, mutualistic fungus that obtains nutrients and inturn provides benefit provides to the host, and saprophytic fungus that are mainly classified as decomposers.
Thus, correct match is as-
A) Parasitic fungus- 4) lives within the blood of another organism and causes disease
B) Mutualistic fungus - 5) lives around the roots of a tree and provides nutrients to the tree
C) Saprophytic fungus- 2) lives in a marsh environment and aids in biodegradation.
