The question is incomplete as it does not have the options which are:
A. The threefold change happened in one concentrated burst.
B. The change was not consistent in direction, but happened in multiple bursts concentrated at each speciation event.
C. There was consistent directional selection toward a larger brain all along the lineage between the two species.
D. None of the above.
Answer:
Option-B
Explanation:
The hominids evolved with time and the known hominid in modern time is the Homo sapiens or modern human.
The Homo sapiens like other species could have evolved from the older species through speciation and studies suggest that one of the major factors of human evolution is the size of the brain.
Two possibilities could explain the size of the brain that it could have evolved slowly with time called the gradual equilibrium or in bursts concentrated at each speciation event.
Since the punctuated equilibrium takes place in bursts until the species reach stasis is the most applicable condition for punctuated equilibrium to happen therefore Option-B is the correct answer.
Answer: d. reverted to washing the coins instead, in accordance with its natural approach to food.
Explanation:
Timulus discrimination is the tendency to lack a conditioned response to a new stimulus that is similar to the original conditioned stimulus. A higher order conditioning occurs when a neutral stimulus comes to act as a conditioned stimulus when combined with another stimulus that already evokes a conditioned response.
Answer:
<em>The water will diffuse into the air.</em>
Explanation:
Diffusion can be described as a process through which molecules travel from an area of higher concentration to an area of lower concentration along the concentration gradient. Such processes do not require energy. As the concentration of water is less in the air surrounding the cell as compared to the inside of the cell hence, the water molecules will move out of the vacuole and into the air by the process of diffusion.
