Answer:
c) thin filaments slide past thick filaments towards the M line
Explanation:
Each muscle fiber has many myofibrils composed of many sarcomeres which have thick and thin filaments. Thick filaments are made of myosin protein whereas thin filaments have actin protein. There are various bands and zones in a sarcomere like A band, I band etc. H zone consists of only thick filaments. It has a central vertical line called as M line where the accessory proteins hold together the thick filaments.
According to sliding filament mechanism, sarcomere must shorten for muscle to contract. However sarcomere shortening is not caused due to shortening of thick and thin filaments. Instead they slide over each other towards the M line which leads to shortening of sarcomere without changing the length of filaments. The sliding is caused by forming of cross bridges between actin and myosin proteins.
Answer:
-The size of sheep olfactory bulb is two to three time larger than humans olfactory bulb.
-Sheep has strong sense of smell that helps the sheep to acquire food.
Explanation:
- The size of the sheep brain is much smaller than humans but sheep has well developed olfactory bulb than humans. The human brain is more circular in shape whereas sheep brain is more extended.
- The well developed olfactory bulb in sheep helps the sheep to find the food. Sheep has strong sense of smell due to large olfactory bulb. Sheep can easily find the location of food located farway from it as the sheep has strong sense of smell.
