In the Hardy-Weinberg formula, 2pq represents the frequency of the Aa genotype (heterozygous).
<h2>c.is the correct option</h2>
Explanation:
Fungi might assist in seed germination by providing the embryos with some of the organic nutrients the fungi have absorbed
- Fungi is an eukaryote which digests food externally and absorbs nutrients directly through its cell walls
- Fungi absorb nutrients through following three ways:
- By decomposing dead organic matter: obtains its nutrients from non-living organic matter, usually dead and decaying plant or animal matter, by absorbing soluble organic compounds
- By feeding on living hosts:fungi live in or on other organisms and get their nutrients from their host
- Living mutualistically with other organisms: mutualistic fungi live harmlessly with other living organisms;fungal component absorb water and minerals and provide them to algal component which uses them to make food
In dark,moist environment nutrient availability is less hence fungi helps in providing orchid seeds the nutrients which it has absorbed
Answer:
<em>The evidence that suggests RNA appeared before DNA is the fact that RNA can act as an enzyme to self-edit their own genetic code. </em>Moreover, it has the ability to store genetic information, while transfer and ribosomal RNA have the ability to translate genetic information into proteins.
Explanation:
RNA has a great capability as a genetic molecule, it once had to carry on hereditary process on its own. It is absolutely sure that RNA was the first molecule of heredity. However, a single stranded RNA is rather unstable and easily damaged by enzymes. By essentially multiplying the existing RNA molecule, and using deoxyribose sugar instead of ribose.
<em>The DNA evolved as a much more stable form to pass genetic information with accuracy. It shows a biological evolutionary purpose .</em>
