Tissues
Cells when grouped form tissues, when group of tissues are formed together they make organs, some organisms skip from organs to organs systems to form an existing organism as a whole<span>. Describing how is the cells group </span>is the process of multiplication of cell or the so-called cell division, mitosis.<span> This mechanism of each cell produces another cell that binds together and produces again, repeatedly, to be a larger system called now the tissue as explained earlier. </span>
The three structures that are most likely found in all fish are: blood, fins, and gills.
1. it <span>supports muscles and tissue
2.it also </span><span>protects the vital organs
3. </span>The skeleton gives the body its shape, which changes with growth. In
addition to determining characteristics such as height and the size of
the hands and feet, stable body shape enables essential functions. For
example, a stable rib cage and spine enable the lungs to fully inflate
when breathing. Conditions such as osteoporosis of the spine and broken
ribs can alter the shape of the chest and impair this vital body
function.

5.Larger bones contain bone marrow, a spongy tissue inside the bones.
There are two main types of marrow, red and yellow. Red marrow is
responsible for production of all of the body's red blood cells and many
of its white blood cells. Red blood cells are produced at an average
rate of approximately 200 million per day. These cells carry
life-sustaining oxygen to the body tissues.
In adults, red marrow is found primarily in the breastbone, hips, ribs,
skull, spinal bones and at the end of long bones of the arms and legs.
Several types of white blood cells, which protect the body from
infections, are also produced in red bone marrow. Yellow bone marrow
contains primary fat cells but can transform into red marrow if the body
needs to increase blood cell production, such as if anemia develops
