p = m / V (Density = Mass / Volume)
p = m / (w * l * h) (Density = Mass / [Width * length * height]) (V = w * l * h)
p = 120 / (5 * 4 * 3) (Mass = 120g [Given] w=5 l=4 h=3 [Given])
p = 120 / 60
p = 2 g/cm^3
Answer is B (2)
<span>The correct option for the question which asks for the difference between terrestrial and aquatic pyramids is option D.

The only eukaryotic organism known to lack mitochondria is the oxymonad Monocercomonoides species.
The answer is; D.
This can be called a secondary ecological succession because it includes the disruption of the former ecology, rather than the ecological succession from a new environment-primary succession. The invasive species outcompete the native species in their environment. In addition, the invasive species lack a natural predator hence spread unregulated in the environment.
Anemia is a medical condition in which there is a decrease int the total amount of red blood cells in the blood and it always results in lowered ability of the blood to carry oxygen. Vitamin B12 is needed to make red blood cells and lack of Vitamin B12 can lead to aneamia. So, the vitamin that is most associated with aneamia condition is VITAMIN B12.
