The testis of a grasshopper is kept in normal saline before dissection to maintain its natural shape, keep it moist, and prevent it from drying out during the dissection process. This helps preserve the structural integrity of the testis and makes it easier to observe and study under a microscope.

Fixation of the testis in place refers to the surgical procedure known as orchidopexy, which is performed to secure an undescended testis (cryptorchidism) into the scrotum. This procedure helps prevent complications such as infertility, testicular cancer, and torsion. By anchoring the testis to the scrotal wall, the operation aims to ensure normal testicular function and development.

The average heart weight of a rat typically ranges from about 1.5 to 2 grams, depending on the rat's size and age. This small size reflects their overall body weight, which is generally around 200 to 500 grams for an adult rat. Factors such as genetics, diet, and health can also influence heart weight in individual rats.
