c) ribosome because that is the site of protein synthesis
Answer:
Perhaps the most amazing thing about mitosis is its precision, a feature that has intrigued biologists since Walther Flemming first described chromosomes in the late 1800s (Paweletz, 2001). Although Flemming was able to correctly deduce the sequence of events in mitosis, this sequence could not be experimentally verified for several decades, until advances in light microscopy made it possible to observe chromosome movements in living cells. Researchers now know that mitosis is a highly regulated process involving hundreds of different cellular proteins. The dynamic nature of mitosis is best appreciated when this process is viewed in living cells.
Explanation:
Answer:
Yes, a fire takes food for energy.
No, a fire doesn't reproduce.
Yes, a fire produces waste.
Explanation:
For fire, the food that it requires is the objects that help in the process of burning. The objects can be wood, paper, coal, fuel, etc. Oxygen is required for the process of burning to take place.
The process of reproduction undergoes in living beings. Fire produces heat and light but this cannot be termed to be a process of reproduction.
Burning produces wastes in the form of ash and burned products. Therefore, it can be said that fire produces wastes.
Answer: D
Explanation: THE PRODUCTS FOR cellular respiration are water CO2 AND energy
Answer:
Option (B), (D) and (E).
Explanation:
Allosteric enzymes may be defined as the enzymes that an change their conformation ensemble after binding to an effector molecule. They play important role in cell signalling and metabolic pathways.
Allosteric enzymes do not obey Michaelis- Menten kinetics. They have two binding sites regulatory site and active site. They contain multiple subunit and exist in more active and less active form depending on the type of substrate and regulatory molecule.
Thus, the correct answer is option (B), (D) and (E).
