Answer:
Desmosomes
Explanation:
The plates holding cells together in tissues are called desmosomes. Desmosomes are the tissue basement. They hold the cells together. So the tissues retain in a definite shape. These are the intermediate filaments and make a net-like structure. These are made up of keratins. It is a structural protein found exclusively in nails and hairs. The desmosomes are 3 types- spot desmosomes, belt desmosomes, and hemidesmosomes. Desmosomes are the connection between 2 cells.
Think of it as a zipper. The top zipper is the leading strand, the bottom is the lagging, and the actual zipper thing is the helicase unwinding the 2 parts. You need the top and bottom strands to have a replication fork
No. It is a liquid substance not a living creature that has the characteristics of life. Yes, it may have bacteria or other living creatures that thrive in water but they are their own separate form of life.
Answer: See if cell phone cases are really a thing you need!
Explanation: Why do so many people use cell phone cases? Do cell phones really need the extra protection, or is it just because cases look fancy? In this engineering science project, you will test the durability of calculators instead of cell phones, find out if cases increase the durability of the device, and build some of your own cases that do!

c, d, a, b, f, g, e
The impulse starts at the SA node that has its own contraction rhythm (but can be faster or slower depending on other impulses or hormones). That impulse travels then through the atria and is slowed down by the atrioventricular septum except for a region in the right atrium called AV node where the impulse has continuity. The impulse travels then to the ventricles through the AV bundle. The impulse continues through bundle branches to other fibers: Purkinje fibers. These Purkinje fibers cause then a contraction that goes from the apex of the heart and rapidly through the ventricles.</span>
