In each stage only 10% is passed !!

As we know not a single animal even human is capable of absorbing whole energy present in glucose !! only 45% of energy present in glucose is used by humans in oxidation !!

so now you can understand the whole food web is not as much efficient !! Thus every time 90% energy is lost as a waste , i am not saying it is lost , it is there but organism is not capable of using that !!

Monica [59]

Answer:

West Nile virus (WNV) causes epidemics of febrile illness, meningitis, encephalitis, and flaccid paralysis. Since it was first detected in New York City in 1999, and through 2004, 16,000 WNV disease cases have been reported in the United States. Over the past 5 years, research on WNV disease has expanded rapidly. This review highlights new information regarding the virology, clinical manifestations, and pathology of WNV disease, which will provide a new platform for further research into diagnosis, treatment, and possible prevention of WNV through vaccination.

Delicious77 [7]

Answer:

The correct answer is explained below:

Explanation:

  • According to the question, heterozygous tall, heterozygous axillary plant has the following genotype, TtAa.
  • It produces the following gametes: TA, Ta, tA, ta.
  • The heterozygous tall, terminal plant has the following genotype: Ttaa
  • It produces the following gametes: Ta, ta.
  • Crossing them,

           TA                       Ta                     tA                        ta

Ta      TTAa                   TTaa                 TtAa                   Ttaa

     (Tall, Axillary)    (Tall, Terminal)    (Tall, Axillary)    (Tall, Terminal)

ta       TtAa                    Ttaa                  ttAa                   ttaa

     (Tall, Axillary)     (Tall, Terminal)   (Short, Axillary)  (Short, Terminal)

  • The genotypes of the offspring obtained are: TTAa, TTaa, TtAa, Ttaa, ttAa and ttaa respectively.
  • The phenotypes obtained are:
  1. Tall, Axillary = 3.
  2. Tall, Terminal = 3.
  3. Short, Axillary = 1.
  4. Short, Terminal = 1.
