Several incomplete statements are listed below. Correctly complete each statement by choosing the appropriate anatomical term from the key. Key:
a. anterior
b. distal
c. frontal
d. inferior
e. lateral
f. medial
g. posterior
h. proximal
i. sagittal
j. superior
k. transverse

In the anatomical position, the face and palms are on the 1 body surface; the buttocks and shoulder blades are on the 2 body surface; and the top of the head is the most 3 part of the body. The ears are 4 and 5 to the shoulders and 6 to the nose. The heart is 7 to the vertebral column (spine) and 8 to the lungs. The elbow is 9 to the fingers but 10 to the shoulder. The abdominopelvic cavity is 11 to the thoracic cavity and 12 to the spinal cavity. In humans, the dorsal surface can also be called the 13 surface; however, in quadruped animals, the dorsal surface is the 14 surface. If an incision cuts the heart into right and left parts, the section is a 15 section; but if the heart is cut so that superior
and inferior portions result, the section is a 16 section. You are told to cut a dissection animal along two planes so that both kidneys are observable in each section. The two sections that will always meet this requirement are the 17 and 18sections. A section that demonstrates the continuity between the spinal and cranial cavities is a 19 section.

15.  Sagittal

16. Transverse

17. Frontal or Transverse

18. Transverse or Frontal

19.  Sagittal

Explanation:

1. Anterior - Because the face and palms are on the front side of the body surface

2. Posterior -  Because the buttocks and shoulder blades are on the back side of the body surface

3. Superior - Because the top of the head is the most upper part of the body

4. Superior or Medial - Because ears are located upward and are very close to the mid-line of the body with respect to shoulder

5. Superior or Medial - Because ears are located upward and are very close to the mid-line of the body with respect to shoulder

6. Lateral - Because ears are at a distance from the mid-line as compared to nose.

7. Anterior - Because heart is in the front side of the vertebral column(spine)

8. Medial  - Because heart is very close to the mid-line of the body with respect to the lungs

9. Proximal - Because elbow is near to the center of the body with respect to fingers

10. Distal - Because elbow is at a distance from the center of the body with respect to shoulder

11. Inferior - Because the abdominopelvic cavity is lower to the thoracic cavity

12. Inferior - Because the abdominopelvic cavity is lower to the spinal cavity

13. Posterior - Because In humans, the dorsal surface has meaning ''in the back side''

14. Superior - Because in quadruped animals ( that has 4 legs ), the dorsal surface is the '' the upper''

15.  Sagittal - Because in sagittal section , the heart cut into right and left part

16. Transverse - Because in transverse section , the heart cut into superior and inferior part

17. Frontal or Transverse - Because in frontal and transverse plane , the dissection of animal can cut so that kidneys are observable.

18. Transverse or Frontal- Because in frontal and transverse plane , the dissection of animal can cut so that kidneys are observable.

19.  Sagittal - Because the continuity between the spinal and cranial cavities is demonstrated in sagittal section.

i would say that hybridization occurs frequently in nature, because there are many types of hybrids that have occurred naturally, such as the mule (male donkey + female horse)
