Folds are bends in rocks whereas faults are displacements of rocks that were once connected to a fault line.
Answer:
Intrusive rocks are coarse-grained in texture and crystallise slowly from magma deep in the earth's crust. Extrusive rocks are fine-grained in texture and crystallise quickly from lava on or near the earth's surface. The mineralogy determines the type of rock.
Answer:
The correct answer for the question: This is the strongest intercellular connection between the functional units of life and it is important in cardiac muscle:____, would be: intercalated discs.
Explanation:
Just like skeletal muscle fibers depend on T-Tubules to be able to propagate an electrical impulse between the sarcomeres that form it, so that all respond in syncronization, myocardial fibers also require to do this; otherwise the heart would simply not function. In the case of myocardium, the muscle of the heart, synchronization is vital in order for it to be able to pump blood and meet the needs of the body. Also, like skeletal muscle, these fibers count with a structure that will permit such a thing; intercalated discs. These discs are formed by the ends of myocardiocytes and extensions of plasma membrane, just like in T-Tubules and they play a vital role not just in unifying the entire muscle fiber, but also adjoining muscle fibers. They also play a vital role in action potential propagation.
Answer: No, because the lysosome and the cell, membrane are needed.
If cells didn't have a membrane, the cell would just melt everywhere. If we didn't have lysosomes, there would be a lot of toxins in the cells.
Hope this helps :)
