Answer:
T3 (tri-iodothyronine) and T4 (thyroxine).
Explanation:
Plant (producer), grasshopper (herbivore) rodent (omnivore), python/snake (carnivore), eagle (carnivore) mushrooms (decomposer) These lines represent the “Animal food chain” and basically represents how one organism eats another organism while showing what they have to eat to survive which is all one ecosystem
Answer:
Option (2).
Explanation:
The cell potential or membrane potential may be defined as the difference in the electric potential between inside and outside of the cell. The membrane potential of the cell changes during the propagation of action potential.
The resting membrane potential is -70mV. The influx of sodium ions causes the depolarization of the cell membrane. The cell potential changes from -70mV to + 30mV. The membrane potential becomes more positive during the depolarization phase.
Thus, the correct answer is option (2).
The correct answer is C. Endemic
Explanation:
In biology, diseases can be classified into different types this includes pandemic, epidemic, and endemic diseases. In the case of pandemics, these are diseases that spread worldwide or in all the population of a species and because of this affects many individuals. On the other hand, epidemics are diseases that spread in many individuals of a species or population and at the same time. Finally, the endemic disease is a type of disease that is common in one species or population and that is constantly present, although only a few individuals are affected by it. Considering this, it can be concluded a disease that is constantly present is endemic.
