In both species repeated pairing of a CS and US eventually produces a CR in response to the CS alone. In the sea-slug this is a very direct process, in the species we have been discussing in these lectures - rats, dogs, humans and so on - I hope you have seen that it is far from being so simple.
Answer:
Telomeres, the ends of chromosomes, shorten as we age, but this process can be slowed through exercise
Explanation:
The following that demonstrates how aging can be influenced by heredity is "Telomeres, the ends of chromosomes, shorten as we age, but this process can be slowed through exercise"
Telomeres are known to be pieces of junk DNA which are usually found at the end of end of chromosomes. The length of telomeres shorten with age.They become shorter and shorter and gets to a point when the cells cannot divide without losing some pieces of DNA. When it shortens, it affects lifespan and health of an individual.
According to the genetic theory of aging, it is seen that genes determine lifespan.
Studies has revealed that exercises helps to lengthen telomeres and also helps the heart and lungs to function well.
Sexual reproduction results in genetic variation in offspring.
Answer:
School is better than virtual learning because you have better one on one connection. With virtual learning, you have to email your teacher and pray she emails you back in time. Though with brick and mortar school, you can walk right up to your teacher and ask for help as you are working. Also, normal school is better because you won't have to worry about internet connection and if your computer is 'compatible'. With virtual learning, you may have to wait a while as your computer loads, but in real school, you have immediate help to all your needs.
