Answer:
Aerobic activity
Explanation:
Aerobic activity can be defined as a type of physical activity which involves the the circulation of oxgen through the blood.
Aerobic activity is an activity which increases the amount of blood that goes to the muscles. Oxygen is needed for the proper functioning of the muscles.
When carrying out any type of physical activity such as weight lifting the muscles need a large amount of oxygen to function well. The oxygen in the body is used to break down glucose and create the fuel which is needed by the muscles in the form of ATP. Different aerobic activities carried out also helps to strenthen the lungs.
The answer is Spiral. Spiral does not represent a type of nebula. There are only 3 types of nebula : Reflection, Emission & Dark. Reflection Nebulaedoes not emit its own light. Instead, it scatters the blue light from a nearby cool star. Emission Nebulae emits own light. Glow very brightly, and are frequently the birthplace of stars. Dark Nebulae also called "absorption nebulae", they block light from brighter objects behind them and can only be seen as an outline in front of a bright nebula or field of stars.
Answer:
A.
Explanation:
bacteria have cell membranes to mimic a normal cell. this protects the bacteria from being consumed by the body's natural defences .
Answer:
The suitable option will be - B
B) Phosphate and ADP form to make ATP which binds to the myosin head and causes cross-bridge to detach.
Explanation:
Until step 11, skeletal muscle has already done cross-bridge and power stroke. ADP is released just after the power stroke. After that phosphate and ADP form a new ATP which gets bound to the myosin head.
Then at step 11, cross-bridge is released as a new ATP is bound to myosin head.
So, we can say that option B is correct.
