These unsegmented worms have a full digestive system even when parasitic.
Answer:
Autotroph
Explanation:
The definition of an autotroph is an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide.
We have the following assumptions:
The temperature of the surroundings remains constant.
The entire surface area of head emits radiation.
From the problem, we have the given values:
emissivity = 0.95
T2 = 36 degrees C
T1 = 9 degrees C
Solving for the area:
A = πD² + πDh = π(21)² + π(21)(20) = 2709.91 cm² = 0.2710 m²
Using the heat transfer equation for radiation:
q = εAσ(T₂⁴ - T₁⁴)
q = 0.95 (0.2710)(5.67 x 10<span>-8)[(36+273)</span>⁴-(9+273)⁴]
q = 3.9 x 10^9 W
