Answer:

Female salmons create the hole where eggs are laid and fertilized by male sperm cells.

Explanation:

Salmon are fishes which live in salt water oceans and fresh water streams. They return to their home stream and lay their eggs at the bottom of the stream by digging it. This is usually done by The female salmon turning on her side and beating the river bed with powerful sweeps of her tail. She does this until the hole is a foot and a half deep. She then lays the egg there which is then fertilized with speed by the male.

She then dies in the same place in which she was born about 5 years earlier.

Drag each label into the proper position to identify whether the indicated structure is located on the femur, humerus, or both.

Evgen [1.6K]

Femur: Greater trochanter-Gluteal tuberosity. Humerus: Coronoid fossa-Intertubercular sulcus-Trochlea-Lesser tubercle-Deltoid tuberosity-Olecranon fossa. Both, femur and humerus: Medial epicondyle-Capitulum-Intercondylar fossa-Lateral epicondyle-Head.

Further Explanation:

Femurs:

femurs or femora, or thigh bone, is the proximal bone of the hindlimb in tetrapod vertebrates. The head of thefemur explains with the hip bone socket in the pelvic bone framing the hip joint, while the distal piece of the femurarticulates with the tibia and kneecap shaping the knee joint.

Humerus:

The humerus is the long bone in the upper arm. It is situated between the elbow joint and the shoulder. At the elbow, it associates essentially to the ulna, as the lower arm's outspread bone interfaces with the wrist. At the shoulder, the humerus associates with the edge of the body by means of the glenoid fossa of the scapula.

Femur or humerus:

Humerus is situated in the upper arm, while femur is found in the upper leg. The length and the normal breadth of the femur are higher than that of humerus.Femur is the biggest bone in the body while humerus is the second biggest. Femur is more grounded than humerus.

humerus and the femur comparative:

The humerus and the femur are relating bones of the arms and legs, separately. While their parts are comparable by and large, their structure has been adjusted to contrasting capacities. The leader of the humerus is practically hemispherical, while that of the femur shapes around 66% of a circle.
