Answer:
One type of control that occurs at the DNA level is the regulator genes. The regulator genes synthesize a repressor molecule that binds to the operator and stops transcription of the structural genes. Whenever there is enough amount of structural genes made, a repressor molecule will bind to the operator region and stop further transcription.
One type of control that occurs at the RNA level is RNA splicing. By this method, different proteins can be made by a single RNA transcript.
<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
