Answer:

Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.

7. Vomer

8. Mandible

9. Maxilla

18. Sternum

19. Costal cartilage

20. True ribs

21. False ribs

22. Floating ribs

Explanation:

The skull comprises the 8 cranial bones that house and protect the brain and 14 facial bones that protect the sensitive organs such as eyes, nose and mouth.
Out of the 14 facial bones, the mandible, maxilla, zygomatic and vomer along with the frontal bone are the primary bones of the skull.
The rib cage comprises of 12 pairs of ribs connected to the sternum, the main bone that anchors the rib cage, through the costal cartilage.
The ribs numbered 1 to 7 are called true ribs because costal cartilage connects these bones directly to the sternum.
The ribs 8 to 12 are classified as false ribs because they are not directly connected to the sternum.
The last two ribs 11 and 12 are called floating ribs because they do not connect to the sternum at all.

In a controlled expierment, what is the expieremntal group compared to?

Sonja [21]

In a controlled experiment, the control group is compared with an experimental group.

Explanation:

A set of variables or data is considered as the control group that remains fixed or constant in its normal usual state; while all the other variables or data are identical with this control group, except one independent variable at a time. This is to observe the changes when that one variable is allowed for variations at a time.

This independent variable which undergoes changes is in the experiment group while the remaining constant group is the control group. The dependent variable changes with changes in the independent variable.

By comparing the control group against the experimental group, uncertainty in results are avoided.
