Why does the earth have different layers?

Biology
1 answer:
Aliun [14]3 years ago
6 0

Answer:

The earth has different layers because as it formed, the lighter parts (like continental crust) floated to the surface, and the really heavy parts (like iron and nickel in the core) sank to the middle. It is just like when you mix oil and water: the oil will float to the surface because it is lighter (or less dense) than the water.

Blood sugar levels of the body need to be maintained, along with what other internal condition?
ASHA 777 [7]

From what we know, we can confirm that the internal body temperature is another internal condition that must be maintained in the body through homeostasis.

<h3>What is homeostasis?</h3>

This is the body's ability to maintain certain internal conditions within a range of values. This is done through a series of feedback loops and other regulatory mechanisms. Temperature and blood sugar are just two of the many conditions included in the mechanisms of homeostasis.

Therefore, we can confirm that the internal body temperature is another internal condition that must be maintained in the body through homeostasis.

In the large intestine material is stored how many<br>hours prior to elimination?​
Sunny_sXe [5.5K]

Explanation:

After you eat, it takes about six to eight hours for food to pass through your stomach and small intestine. Food then enters your large intestine (colon) for further digestion, absorption of water and, finally, elimination of undigested food. It takes about 36 hours for food to move through the entire colon.

Describe the difference between the lytic cycle and lysogeny when bacteriophage infection occurs.
Shkiper50 [21]
Both are methods of viral multiplication inside the host cell.
 Lytic cycle (which is more common) includes steps like:
<span>1. Infection of the host cell-virus attaches to the receptor of the host cell, penetrates it and releases its genetic material into the host cell.</span>
<span>2. Virus Multiplication-Virus incorporated its genetic material into the host’s and uses its metabolism to multiply. Viral genetic material replicates separately from the host DNA.</span>
<span>3. Cell Destruction-  Virus releases an enzyme that breaks the cell wall from within, thus destructing the host cell.</span>  
<span>Lysogenic cycle also includes steps of infection, penetration and incorporation of the genetic material. But, after the virus integrates its genetic material it becomes dormant, letting the host multiple and continue its normal activities. Viral genetic material replicates within the host DNA during the host cell's division, so the daughter host cells are infected too.<span> At some point, the virus is triggered, it multiplies and ultimately, destroys the host cells.</span></span>
