You are wondering if food source alone was driving the pine and oak jay groups to have
different bill lengths. Therefore, you decide to investigate if the jays choose to mate only
with other jays that have the same bill length.
Island scrub jays stay with the same mate for life. You compared the male and female bill
lengths for 42 breeding pairs.
The graph below shows data you collected about the island jays' mating behavior.

3. List three other types of evidence that plants existed in Antarctica. (besides that there were plant fossils found)
GalinKa [24]

The three evidence that support the existence of plants on Antarctica are:

- Climate;

- Pollen;

- Herbivorous animals;

Apart from the plant fossils found on Antarctica, there are few other evidence that suggest that plants existed in the past on the now frozen continent. Some of those evidence for the existence of plants on Antarctica are the pollen found in the rocks and fossils of organisms, the climate records, as well as the herbivorous animals.

The pollen is only released by the plants, thus that is a sure indicator that plants were occupying this part of the world.

The climate records on Antarctica that can be seen in the rock layers, suggest that for most of its existence, Antarctica had a warm and wet climate, which is perfect conditions for the plants to thrive.

The herbivorous animals are feeding themselves on plant material, so since there's fossils of herbivores in Antarctica, it for sure is an evidence that there were plants existing in order for them to feed and be able to live in there.

What is the location of the compact bone and the sponge bone?
Natasha2012 [34]
<span>Compact bone is the external or outer layer of a bone that gives bone tissue a "hard-like" feel, while a spongy bone is the inner bone. Spongy bone is porous and sits underneath the compact bone. If spongy bone does not receive ample calcium nutrients, it is most vulnerable to breakage.
