Suppose you buy some stock in the Alpha Corporation at a price of $45.95 per share. 410 days later you sell the stock for $48.27. During this period you received a per share dividend of $1.20. What is your annualized return on this investment

6.79%

Explanation:

The holding period return is:

= (Current price - Cost price + Dividend) / Cost price

= (48.27 - 45.95 + 1.20) / 45.95

= 7.66%

The annualized return is:

= ( ( 1 + holding period return) ^ number of days in a year/ number of days stock was held - 1)

= ( ( 1 + 7.66%) ³⁶⁵ / ⁴¹⁰ - 1)

= 6.79%

ans.

heterothermic organisms include those organisms that can switch between homeothermic (having body temperature higher than environment) and poikilothermic (having variation in internal body temperature) strategies.

some migratory birds show heterothermy as they decrease their metabolic rate during cold nights to keep their body temperature low. drop in metabolic rate allows increase in production efficiency of birds that reduces the internal body temperature to make it equal to external cold temperature during cold nights.

thus, the correct answer is 'birds allow their temperature drop in order to increase their production efficiency.'
