Answer;
Internal layer of spongy bone in flat bones.
The term diploe refers to the internal layer of spongy bone in flat bones.
Explanation;
Diploe is the soft material that is between the hard and the outer walls of the bones of the cranium.
It is the endosteum (delicate connective tissue that covers the trabeculae and canal of the spongy bone) covered trabeculae of a spony bone.
Diploe is found in short, irregular, and flat bones.
Fossil fuels are found in the outer-layer of the Earth called the crust.
<h2>Kinase cascade </h2>
Explanation:
Normally, PK2 activates PK1
- PK1 and PK2 normally work sequentially in an intracellular signaling pathway
- If PK1 is permanently activated, a response is seen independently of whether or not PK2 is present
- If PK1 activated PK2, no response should be seen if PK1 were activated in the absence of PK2
- PK2 normally needs to activate PK1 for the cells to respond to the signal
- When PK2 is permanently activated in the absence of PK1, PK1 is not there to relay the signal
