A. off a surface at the same angle it strikes the surface
This finding indicates the damage of the mid-brain
This is evident due to the Decerebrate posturing, which is characterized by abnormal extension in response to painful stimuli, that indicates damage of the midbrain. On the other hand, damage to the diencephalon or cortex, abnormal flexion, occurs when a painful stimulus is applied. While medulla damage results in flaccidity.
What is the choices for the blank?
Answer:
Physical Weathering
Explanation:
As per the given conditions in the question, the primary effect is <u>mechanical action</u> which is also known as a <u>physical weathering</u>. During mechanical action, a rock is disintegrated into the smaller pieces. In the given statement, <u>the root of tree would grow in the crack and try to develop a strong network to get nutrients necessary for tha tree growth</u>. Thus, the <u>root would exert a pressure</u> in the crack to make more space for its growth and development (root network). This is primarily a mechanical action and an example of physical weathering.
Species selection. Species selection is the process by which intrinsic biological characteristics in organisms change depending on the type of environment they're interacting with. In this case, the subsequent generations of the fly lost the ability to fly because their environment didn't require them to use wings for survival, hence they stopped growing them and subsequently lost the ability to fly.
