Question is incomplete i have added complete question in ask for detail section and at the end of this question.
Answer:
b. using negative feedback to decrease blood glucose levels
Explanation:
When the level of glucose increases in the blood and become higher than the normal level a negative feedback mechanism is initiated under the control of hypothalamus. which increase the metabolism of excessive glucose level present in blood and hence results in decrease or normalization of glucose level in blood.

Answer:
1. Growth on cornmeal agar
2. KOH prep
Explanation:
Cornmeal agar is a nutritional deficient media containing :
- Corn meal 8g / zein 40 g / 100ml
- Agar 4g
- Distilled water 200 ml
- Large , highly refractory, thick walled.
KOH preparation (10 - 30% ) used to destroy keratin, leaves fungal hyphae.
- Can add a chitin-specific stain
- Calcofluor white fluorescent stain increases sensitivity
Hence the organism can easily be identified by these two tests.
