Answer:
Organisms with variations that makes best suited to their environment are more likely to survive.
(Darwin's theory)
Answer:
As one of our most vital senses, the capacity to hear allows us to connect to the world for numerous very critical reasons. Most notably, hearing joins us to people enabling us to communicate in a manner that none of our different senses can accomplish.
Explanation:
Hearing allows us to connect with the world around us, it's beneficial to communicate with others, be able to listen for dangers, etc. Our ears can detect all sorts of noises, and all of these sounds have some sort of importance to us. Some noises can indicate danger, which is vital for survival. Hearing is also crucial for socialization; on average, a person will hear up to 70,000 words a day!
I hope this helped!! :)
Answer:
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + ATP
Explanation:
There are two types of respiration:
1. Aerobic respiration
2. Anaerobic respiration
Aerobic respiration
It is the breakdown of glucose molecule in the presence of oxygen to yield large amount of energy. Water and carbon dioxide are also produced as a byproduct.
Glucose + oxygen → carbon dioxide + water + 38ATP
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + ATP
Anaerobic Respiration
It is the breakdown of glucose molecule in the absence of oxygen and produce small amount of energy. Alcohol or lactic acid and carbon dioxide are also produced as byproducts.
Glucose→ lactic acid/alcohol + 2ATP + carbon dioxide
This process use respiratory electron transport chain as electron acceptor instead of oxygen. It is mostly occur in prokaryotes. Its main advantage is that it produce energy (ATP) very quickly as compared to aerobic respiration
