The humerus-
A long bone of the upper forelimb. It articulates proximally with the scapula to form the soulder joint and distally with the radius and ulna to form the elbow joint.
<span>Proximally the humerus has a rounded projection known as the head. </span>
Cranially at the lateral aspect of the head is a large prominence- the greater tubercle. The lesser tubercle lies medially. Both tubercles act as a sight for muscle attachment. At the distal end of the humerus is a condyle which articulates with the radius & ulna & forms part of the elbow.
The diaphysis of the humerus is twisted.
<span>In the dog a supra condylar foramen is present- a large hole in the condyle.

The Femur-This is the thigh bone and is the largest bone in the body, it is a long bone and is similar in structure to the humerus in that it has a head, neck, shaft & lateral & medial condyles. The femoral head articulates with the acetabulum proximally to form the hip joint, lateral to the head is the greater trochanter and on the medialTh side is a lesser trochanter (for muscle attachment). At the distal end of the femur are 2 condyles that articulate with the tibia to form the stifle joint. Between the 2 condyles is the trochlear groove along which the patella can move.
Here is some information. Hope this helps ☺
D. Polar regions receive less solar energy and heat per unit area than tropical regions
Less direct sunlight means that there is less concentration of direct solar rays. This would influence temperature and would ultimately create weather, and since this pattern continues of switching direct ray latitudes, this would create climate zones all over the Earth, and similar ones with similar latitude and terrain.
The Answer to this question is b
<span>A person who has rh- blood can develop rh agglutins through;
1. Pregnancy.
2. Transfusion.
3. Exposure to blood.
Agglutination is termed as clumping of particles. It is the process which occurs when an antigen is mixed with its corresponding antibody known as isoagglutinin.
When people are being given blood transfusion of wrong blood group then the antibodies will react incorrectly with the transfused blood group, then the erythrocytes clump up and stick together which causes them to agglutinate.</span>
A desert would be a good example because there is no exact source of water there unless you are in a specific one.
