The beginning of the Cambrian Period is marked by the evolution of hard body parts such as calcium carbonate shells. ... These body parts fossilize more easily than soft tissues, and thus the fossil record becomes much more complete after their appearance.
Answer:
Variation. Organisms (within populations) exhibit individual variation in appearance and behavior.
Inheritance. Some traits are consistently passed on from parent to offspring.
High rate of population growth.
Differential survival and reproduction.
Explanation:
Answer:
0 meters
Explanation:
When we talk about displacement, think that the think of it as the measure of the distance between the starting point of the object, from its end point.
Since we are talking about a lap around a track, it would mean that the starting point is also the end point. So if you started and end at the same point, the distance between it would be 0.
Answer:
d. occipital
Explanation:
If most of us are able to sense every visual stimulus around us, it is essentially due to the occipital lobe, the area of our brain located at the nape of the neck.
Our understanding of the world is based almost exclusively on the sense of sight. The occipital lobe processes visual stimuli permanently, analyzing distances, shapes, colors, movements and etc.
Everything that arrives through the retina passes through this analysis and processing center (occipital lobe) which then sends the information to the cerebral cortex. However, this transfer of information must first go through a series of areas, but it is correct to say that the occipital lobe is the part of the cerebral cortex that contains the airs associated with vision.
