Answer:
Option B
Explanation:
In biology, fitness refers to the ability of an organism to survive, reproduce, mate and support evolution through gene transfer. A fitness of 0.28 signifies that only 28 percent of a given population are fit physically and able to reproduce while the remaining 72 % are unable to mate and hence cannot reproduce and contribute towards gene flow and evolution.
Hence, option B is correct

Fungi are eukaryotic organisms .they are feed on dead, decaying matter because they lack chloroplast. Most fungi are parasitic or symbiotic.
Fungi lacks root, stem and leaves. They however posses threadlike filaments called hyphae, which forms a larger mass called mycellium. Fungi reproduce asexually by spores. The classification of fungi are;
#zygomycetes, also called conjugation fungi .eg bread mold
#ascomycetes, also called sac fungi eg baker's yeast
#deuteromycota, also called imperfect fungi eg penicillium
#basidiomycetes .they are the commonly known mushrooms. They grow on wood and trees. Most of their species are edible. They are also called club fungi
Answer:
The correct answer is "9 cycles".
Explanation:
The minimum number of cycles necessary to replicate a fragment of DNA over 500 times is 9 cycles. In Polymerase Chain Reaction (PCR) method, the fragments of DNA are doubled in each cycle. This means that after "n" cycles, the total number of fragments is given by the equation 2^n. In this case, after 9 cycles a total of 512 DNA fragments will be obtained, because 2^9 is equal to 512.
