Recycling light energy to be used in the process of photosynthesis
Potatoes are an example of Tubers.
Answer:
a) 
b)
c) 
d) 
Explanation:
The correct question is
Organisms with the genotypes AABbCcDd and AaBbCcDd are crossed. What are the expected proportions of the following progeny?
a. A_B_C_D_
b. AabbCcDd
c. a phenotype identical to either parent
d. A_B_ccdd
Solution
In such question the probability for each allele pair is to be determines separately
For instance,
AA * Aa will produce AA, Aa, AA, Aa this means that all the the probability of getting both AA and Aa is 
Like wise when Bb and Bb are crossed, BB, Bb, Bb, and bb are produced. So the probability of getting dominant trait i.e BB or Bb is
and recessive trait i.e bb is 
Chance to get homozygous bb only or BB only is 
and chance of getting Bb is 
Like Bb and Bb cross, the same will be the probabilities for Cc and Cc cross and Dd and Dd cross

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.
