Did the T. Rex have an amniotic egg?

Question 15 options:

Probably not because there is no history of closely related animals having an amniotic egg.


It is quite likely because lots of animals in the past have had amniotic eggs, so the T. Rex probably did too.


It is quite likely because both the caiman and parrot have an amniotic egg and they share a recent common ancestor with the T. Rex


Probably not because the T. Rex is no longer living.

Read the excerpt from How Hurricanes Form.

Hurricanes are often compared to engines. Just like engines, they need a type of fuel. Hurricanes form over warm ocean waters near the equator. For hurricanes, their fuel is warm, moist air. When hurricanes form, the warm, moist air above the ocean rises upward from close to the surface of the water. Because the warm air rises, it results in less air under the surface of the water. This area with less air is known as an area with low pressure.

Air from areas surrounding this low pressure space pushes in to the area. This fills the low pressure area. The new air in this space becomes warm and moist and also rises. As the air continues to rise, the air surrounding the space swirls in to take its place. This process of air swirling in to replace air that has risen continues. Eventually, the moisture in the air forms clouds.

The wind and the clouds that form create a system. A system is a pattern of weather. The system of clouds and winds continues to spin and grow. The water evaporating from the ocean's warm surface acts as the fuel, which is what helps this spinning and growing. The system rotates faster and faster until the eye of the storm forms in the center area. Ironically, the eye of the storm is the calmest part, and it has very low air pressure. The higher pressure above the hurricane continually flows down into the eye.

A science class is doing an experiment on how light affects the growth of plants. One set of plants is placed under a special light, a second set
of plants is placed in the dark. A third set of plants is left under normal room lights. The class measures and charts each plant's growth for a
week.
In this experiment, the third set of plants that was placed under normal room lights would be identified as the

A can of antifreeze spills near a clump of Dryopteris dilatata, a type of fern. The chemical seeps into the ground, endangering the plant's roots. The plant roots grow as far away from the chemical as possible to absorb only fresh water and minerals.
During this process, the roots primarily work in conjunction with which system? a) The immune system to defend against the toxic chemicals
b) The vascular system to reduce the absorption and transport of toxic chemicals
c) The reproductive system to make more root cells
d) The digestive system to create enzymes that break down the toxic chemicals​
