<span>False. E.coli is generally about 2 micrometers in size compared to white blood cells which are around 13 micrometers in size. Also, white blood cells have a characteristic segmented nucleus with two to five lobes joined by fine strands of chromatin.</span>
Answer:
Digestion is the process of breakdown of the large food particles into the small substances and absorbed by the body. The digestive enzymes and digestive juices are required for the digestion.
The Marisol digestive system is not working although she swallow her food. This may affect her exercise as the cells are not able to get work. The food particles are not broken down and absorbed by the cells, This causes the energy deficiency in her cells and she is not able to do normal physical work properly.
Structure A is used for (4) cell communication. The cell membrance has receptros for cell communcation.
Structure B is used to (1) extract energy from nutrients. The mitochondria is the power house of the cell.
Structure C is used for (1) protein synthesis. The golgi apparatus is where protein is created.
As our all basic needs is fulfilled by aerobic respiration but when it comes to vigorous exercise when there is a shortage of oxygen , muscles starts using anaerobic respiration to full fill the need !
another example of anaerobic respiration in our body is in RBC ! Here there is no mitochondria so it has to do anaerobic respiration !
<u>Change in thermal energy and particle arrangement of molten steel after becoming completely solid:</u>
Due to the rise in the temperature, the particles start moving speedily. Because of the achieving the kinetic energy, which helps in the higher collision rate and makes the diffusion rate high. In case of the solids the particles are strongly bound in sequential order. Even though we can’t see it, but the vibrations can be felt. During heating the internal energy increases and helps the particle to move faster.
