With each contraction cycle, actin moves relative to myosin. ... ATP can then attach to myosin, which allows the cross-bridge cycle to start again; further muscle contraction can occur. Therefore, without ATP, muscles would remain in their contracted state, rather than their relaxed state.
Answer:
The correct answer is: None of the above. The accurate answer is: Problem or inability in detecting the sensory information.
Explanation:
- Sensory receptor cells form the part of the sensory epithelial layer that are present in the form of a lining in all sensory organs.
- These sensory cells possess some specialised receptor molecules, usually on the surface of the cells, that can sense different types of sensory signals like light, in case of eyes, smell is case of nose, taste in case of tongue and sound in case of ears.
- Any damage caused to these cells will adversely affect their capability to perceive or receive or detect the sensory signals.
- Option I is incorrect because sensory cells are not only present in the eyes and ears but also in nose, tongue, skin. The activity of the sensory cells of one organ is independent of the activity of sensory cells of other organs hence, damage to the sensory cells of one organ will not create any confusion in different sensory inputs.
- Option II is incorrect because integration of all the sensory impulses occur in the brain after the impulse has been received and detected by multiple sensory receptor cells and send to the brain through the sensory neurons.
Answer:
Explanation:
1. Topoisomerase is an enzyme helps in over winding Or underwinding of DNA during replication. Helps in the topological correction. So non-functional topoisomerase leads to tangled DNA and prevents replication..
2. Primases are the enzymes helps in the synthesis of short RNA sequences used as primers in replication. Non functional primase leads to no primer synthesis.
3. DNA Polymerase is an enzyme helps in the addition of new nucleotide to the growing strand in replication. Non functional DNA polymerase prevents the strand growing as no new nucleotides were added.
4. Helicases are the enzymes helps in the separation of double strands into single and helps in each strand to be copied. Non functional helicase leads to prevention of unwinding of strands and replication inhibition.
5. ligase is an enzyme that joins nicks(small gaps) in the DNA strand by creating ester bond. Non functional ligase leads to unjointed gaps of lagging strand.
6. Single strand binding proteins(SSB's) are the small proteins that binds to the single strands of DNA and holds them in a place not to get together while replicating. Non functional SSB's leads to parental strands come back together and prevents replication.
Answer: Birds pick up oil on their beaks, by rubbing against the uropygial or preen gland near the tail, and then rub it over their feathers. This makes the water unable to break through the oil.
Explanation: Hope this helps have a great day :)
Every cell in the body goes through a life cycle. Cells grow and divide to replace cells that are lost because of normal wear and tear or injury. Different cells grow and die at different rates. Some cells, such as epithelial<span>epithelialA thin layer of epithelial cells that makes up the outer surfaces of the body (the skin) and lines hollow organs, glands and all passages of the respiratory, digestive, reproductive and urinary systems.</span> cells, reproduce quickly. Other cells, like nerve cells, grow slowly. Both normal cells and cancer cells go through a sequence of steps, or phases, when they form new cells. This is called the cell cycle.
