The process of cells producing energy is metabolism.
This happens from respiration in organisms (animals to plants to bacteria).
Can be written as:
Respiration = Oxygen(O2) + Glucose(C6H12O6) = Water(H2O) + Carbon dioxide(CO2)
Hippos likely evolved from a group of anthracotheres about 15 million years ago, the first whales evolved over 50 million years ago, and the ancestor of both these groups was terrestrial. These first whales, such as Pakicetus, were typical land animals. They had long skulls and large carnivorous teeth. Hope I’ve helped ;)
The scheme of modern taxonomy goes:
Life > Domain > Kingdom > Phylum > Class > Order > Family > Genus > Species
So, a PHYLUM is made of several classes.
A pulse with unpredictable pattern is termed as an <em />irregularly irregular pulse. This kind of pulse coincides with an irregularly irregular heart rhythm seen in those with severe arrhythmias such as 3rd degree AV block. In contrast, there is a pulse that is irregular but has a predictable pattern termed as regularly irregular.
