The ischium bone forms the superior part of the pelvic girdle.
<h3>What is the structure of the pelvic girdle?</h3>
In the bottom region of the trunk, there is a bony structure known as the pelvic girdle that resembles a ring. It joins the lower limbs to the axial skeleton. There are two types of pelvises: the bigger pelvic and the lesser pelvis.
The pelvis is made up of two paired hipbones that are joined at the pubic symphysis in front and by the sacrum in back. Each hipbone is composed of three bones: the blade-shaped ilium above and to either side, which determines the hips' width; the ischium below, on which the weight is placed when sitting; and the pubis in front. Early in maturity, all three come together at a triangle suture in the acetabulum, the cup-shaped socket that connects to the head of the femur to create the hip joint.

Some man-made fibres, too, are derived from naturally occurring polymers. For instance, rayon and acetate, two of the first man-made fibres ever to be produced, are made of the same cellulose polymers that make up cotton, hemp, flax, and the structural fibres of wood.

Answer:
The primary function of the photosystem I is in NADPH synthesis, where it receives the electrons from PS II. The primary function of the photosystem II is in the hydrolysis of water and ATP synthesis. The PSI is made up of two subunits which are psaA and psaB.
<u>Here are the basic steps:</u>
Light absorption in PSII. When light is absorbed by one of the many pigments in photosystem II, energy is passed inward from pigment to pigment until it reaches the reaction center. ...
ATP synthesis. ...
Light absorption in PSI. ...
