Hemophilia can result in: Bleeding within joints that can lead to chronic joint disease and pain. Bleeding in the head and sometimes in the brain which can cause long term problems, such as seizures and paralysis. Death can occur if the bleeding cannot be stopped or if it occurs in a vital organ such as the brain. Complications of hemophilia can include: Deep internal bleeding.

The vertebral column of human consists of 33 bones at birth, the lower 9 bones fuse into two separate bones and the upper 24 bones are separated and articulated by intervertebral disc during adult stage. T

The number of bones in the vertebral column is 26 where 7 are cervical vertebrae, 12 thoracic vertebrae, 5 lumbar, 1 sacral (fused) and 1 coccygeal (fused) vertebrae. T

The constant movement of particles when seen under a microscope is a very common observation known as Brownian motion.

All particles are made of atoms. Atoms are comprised of three components:

the first two comprise the core of an atom, surrounded by a cloud of electrons.

Though much too small to be seen without aid, these atoms do indeed possess mass and are capable of colliding with one another. Particles constantly collide with one another and are bounced in the opposing direction, over and over again. This is precisely what we observe under the microscope as particles bouncing around and is referred to as Brownian motion.

Answer:

The hormone erythropoietin regulates enthrocyte production, which is produced in the kidneys.

Explanation:

Bone marrow is the body organ responsible for controlling erythrocyte (red blood cell) synthesis.

The process of erythropoiesis, which occurs largely in the bone marrow, produces erythrocytes. Hematopoietic stem cells, which can differentiate and develop into several types of blood cells, including erythrocytes, are found in the bone marrow.

The hormone erythropoietin (EPO), which is produced and secreted by the kidneys in response to low oxygen levels in the body, regulates the formation and release of erythrocytes. EPO stimulates the formation of erythrocytes in the bone marrow, maintaining an adequate supply of oxygen-carrying red blood cells in the bloodstream.
