Because the chromatin condenses into compacted chromosomes.
<span>During mitosis, chromatin condenses starting from the prophase to the end of cell division. Condensation of chromatin protects the DNA during cell division and facilitate its mobility and transport. </span>
Answer and Explanation:
The steps of the sliding filament theory are:
Muscle activation: breakdown of energy (ATP) by myosin.
Before contraction begins, myosin is only associated with a molecule of energy (ATP), which myosin breaks down into its component molecules (ADP + P) causing myosin to change shape.
Muscle contraction: cross-bridge formation
The shape change allows myosin to bind an adjacent actin, creating a cross-bridge.
Recharging: power (pulling) stroke
The cross-bridge formation causes myosin to release ADP+P, change shape, and to pull (slide) actin closer to the center of the myosin molecule.
Relaxaction: cross-bridge detachment
The completion of the pulling stroke further changes the shape of myosin. This allows myosin and ATP to bind, which causes myosin to release actin, destroying the cross-bridge. The cycle is now ready to begin again.
The repeated cycling through these steps generates force (i.e., step 2: cross-bridge formation) and changes in muscle length (i.e., step 3: power stroke), which are necessary to muscle contraction.
<span>When the lid for a vat
of wine is slightly open, the yeast inside can continue to perform alcoholic
fermentation because the carbon dioxide produced by the yeast during
fermentation will act as a blanket over the wine. Nevertheless, the air around the fermenter
must be still and enough carbon dioxide should be produced to continue
alcoholic fermentation. However, at some point, carbon dioxide will fall and
can no longer protect the wine. This is the right time to get your wine covered
before it will be vulnerable to undesirable microorganisms. </span>
Therefore, open fermentation
is good in the early stages of fermentation because yeast need oxygen to synthesize sterols and assimilate
fatty acids to ensure the nutrients it needs to multiply and ferment the 70% of the sugar from the fruit. Furthermore,
the yeast is responsible in decomposing sugar from the grapes into alcohol and
carbon dioxide.
Answer: The term volcanic mountains suggest that they are formed by volcanoes. When a tectonic plate subducts beneath another, magma is pushed to the surface.
