Answer:
Neil Shubin bases his argument that the anatomy of Tiktaalik is relevant to that of humans by discussing specific features of the anatomy of Tiktaalik that vary from typical fish anatomy and correspond to features of the human body. For example, he points out that Tiktaalik has a neck that is able to bend independently of the rest of the body, unlike fish, and like all terrestrial vertebrates, including humans. Therefore, the evolutionary history of humans can be traced to an organism similar to Tiktaalik, resulting in the concept of the "inner fish."
Explanation:
The seismic waves that travel through Earth’s interior are
known as the P waves and the S waves, these seismic waves have differences,
first the P waves compress and enlarge the foundations(rocks) as they move
through it, while the S waves, shakes the particles of their medium up and down
and side-by-side. P waves can travel through solid granite, magma, water or
even air, while S waves can only travel through solids, they are unable to
travel through fluids. The P waves are the fastest of all known seismic waves,
it is the first seismic wave to register on the seismograph, while the S wave
is the second one.
According to the gate control theory of pain, the structure that is the likely location of the gate is the substantia gelatinous.
<h3>
What is substantia gelatinous?</h3>
- A group of cells called the substance gelatinosa can be found in the spinal cord's gray matter (dorsal horns).
- It receives direct input from the dorsal (sensory) nerve roots, particularly those fibers from pain and thermoreceptors, and is present at all levels of the cord.
- The spinal cord has a system that permits pain signals to be amplified in the brain before being processed at the spinal cord itself, or attenuated there, in accordance with the Gate Control Theory of Pain.
- The "gate" is the device that either permits or forbids the transmission of pain signals.
- To feel intense pain if the gates are more open since many more pain signals will flow through to the brain.
- The likelihood that you will feel less discomfort increases as the gates are more tightly shut.

Answer:
VIDA means: Variation, Inheritance, Differential Survival and Reproduction, Adaptation. These principles apply not matter what organism you are studying

D, because if white cattle are rr and red cows are RR, then roan cattle
are Rr. Therefore, a cross of Rr x RR would result in half RR and half
Rr.</span>
