HETEROTROPHS
Explanation:
Autotrophs are any organisms that are capable of producing their own food. For most, this is achieved by using light energy, water and carbon dioxide. Heterotrophs cannot produce they have to absorb.
One reason why a species may go extinct is due to environmental changes. For example, if a environment undergoes deforestation / wild fires it’s environment will no longer be grassy green and would not allow for an animal like the Japanese rat snake to use its green coloring to camouflage from predators
DNA- Deoxyribonucleic Acid is a molecule composed of two chains or double strands that coil around each other forming a double helix to carry the genetic information for the development of an organism.
<u>Explanation:</u>
- DNA contains the information that instructs a living organism to develop, grow, survive and reproduce.
- The information instructed is found inside every cell and is passed down from parents to their children.
- DNA is made of nucleotide molecules which in turn contains a phosphate group, a sugar group, and a nitrogen base.
- Deoxyribose in DNA is another form modified from ribose sugar.
Answer:
The mentioned parental types are c+m- and c-m+. Thus, the recombinants will be c+m+ and c-m-.
Now, the given distance between c and m is 8 map units. Thus, the recombinant frequency is 8% or 0.08.
The total recombinants from 1000 plaques will come out to be 80,
Thus, the recombinants of each type will be 40.
Total parental type will be 920, and therefore, each parental type count will be 460.
Thus, expected c+m- = 460, expected c-m+ = 460, expected c+m+ = 40 and expected c-m- = 40.
