The tissue to have cells with the greatest number of gap junctions is the cardiac tissue.
Cardiac tissue refers to the involuntary, striated tissue present in the heart. It is made up of individual heart muscle cells called the cardiomyocytes. They are joined together by intercalated discs which contain the gap junctions. Gap junctions are the specialized intercellular connections which link the cytoplasm of two cells. Gap junctions play a crucial role in regulating the velocity and safe impulse propagation in the heart. They are abundantly found in the cardiac tissue helping in direct transmission of the deplolarizing current from cell to cell across the chambers of the heart. The signals for contraction of the cardiac muscle is passed through these gap junctions.
This is because twenty-four latitude lines were chosen so that 24 hours represents a 360 revolution around the planet. As earth spins on its axis, different places receive sunlight at different times. Each day goes from morning to night as earth turns because the earth spins from west to east therefore the day moves from east to west. Lines of longitude help us keep track of time differences from place to place. Mapmakers divided earths 360 degrees of longitude by 24 hours which results to 15, the time changes by one hour every 15 degrees. It is one hour earlier every 15 degrees of longitude to the west and it is one hour later every 15 degrees of longitude to the east.
The two point discrimination test
is used to determine sensitivity to touch. This test is performed to evaluate the
ability of an individual to identify two close points on a small area of skin
and how well the individual can discriminate the points. The test can be done by
using calipers.
Based on my research Diffusion is the answer here because it is part of osmosis and it happens when molecules can pass through a permeable membrane through a smaller space then spreads out to a larger space.
active transport is the movement of atomic substances across a cell membrane with the help of energy and enzymes.
Passive transport is the movement of atomic substances across cell membranes without the help of any force or energy.
Selectively permeable membrane is a type of membrane that allows selected molecules or atomic substances to enter the membrane from where osmosis can happen.
