Answer:
A myosin head bound to actin
Explanation:
Cross bridge cycling explains the sliding filament theory according to which thin and thick filament slide against each other for muscle contraction. The two myosin heads extend form the thick filament. One myosin head has binding site for ATP and other head has binding site for actin from thin filament.
When myosin head binds to actin a cross bridge is formed. When ATP binds to the other head the bridge dissociates. Actin binding site is free and myosin tries to bind with other actin during which ATP is hydrolysed into ADP and Pi. Myosin along with the ADP and free Pi successfully binds to another actin molecule. The cross bridge formed generates a powerful force and ADP and Pi are displaced from it. The cross bridge is now free again for binding of next ATP molecule and the cycle continues.
<u>Answer:</u>
Gravitational redshift, changes in a planet’s orbital path, gravitational lensing provides the concrete evidence for the general theory of relativity.
<u>Explanation:</u>
- Due to the slowing of time in very 'strong gravitational field' the gravitational redshift occurs.
- The low frequency of the light occurs in the red part when we observe the electromagnetic spectrum.
- The appearance of light is seen slightly shifted to the 'red wavelength'.
- The matter in the galaxies that bends the light from a source at a distance reaching the observer is also a evidence which is termed as gravitational lensing.
Answer:
The correct answer will be- Option-4
Explanation:
Carl Woese is well known for dividing the five-kingdom system into three domains: Archaebacteria (ancient bacteria), Eubacteria and the Eukaryotes on the basis of the studies of the ribosomal RNA.
Since the three-domain system does not include the cyanobacteria group which includes the photosynthetic bacteria therefore, the Cyanobacteria is the correct answer.
Thus, Option-4 is the correct answer.
