Which of the following is a result of a limiting factor in an ecosystem? a. A pond has only produced a small amount of algae, so the fish population is also small.

b. The weather was extra humid last summer and there were more mosquitos than ever before.

c. A farmer planted new grass and months later his animals looked healthier than they’ve looked in years.

d. This year, ticks are supposed to be worse than in previous years, with a huge number of them carrying Lyme Disease.

We want to calculate the total metabolic heat generated by a singing canary taking into account heat transfer by radiation, convection and exhaling air. the air temperature is 20 oc, canary’s body internal and surface temperature is 33oc, external body surface convective heat transfer coefficient is 25.2 w/m2 .k, temperature difference between the inhaled and exhaled air is 4.3 oc, the ventilation rate is 0.74 cc of air per second, specific heat of air is 1.0066 kj/kg. k and density of air is 1.16 kg/m3 . assume the canary’s body to be a cylinder with 7 cm diameter and 9 cm length, and heat exchange is from the side as well as the top and bottom of cylinder. calculate 1) the net rate of heat lost by radiation, assuming heat gained by the bird through radiation from the surroundings is 11.5 w; 2) rate of heat transferred by convection to the surrounding air; 3) rate of heat transferred in the exhaling air without considering any internal evaporation; 4) total metabolic power.

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.

Write the function getkthdigit(n, k) that takes a possibly-negative int n and a non-negative int k, and returns the kth digit of n, starting from 0, counting from the right
