Answer:
Sensation.
Explanation:
The sensory receptors are responsible for the detection of stimuli. The bottom up and top down control are the two important processing that helps in the introductions of sensory information in the body.
Sensation is the process by which the organisms detect the internal as well as external stimuli. The three main process that are involved in sensation are detection of stimuli from the environment, the change of stimuli in electrical signal and then received by the brain for further processing.
Thus, the correct answer is sensation.
Answer:
B. Biological Evolution
Explanation:
The biological evolution or evolution is a process by which organisms changes over time and the heritable traits are passed on to the successive generations.
The traits which increase the survival rate or reproductive fitness become permanent in the population when they are passed on to the generations.
In the given question, all the organisms possess DNA, use energy and perform metabolic functions is the result of the transfer of the traits as these characteristic feature allows the cells to survive and thus allows the organism to survive in the different conditions.
Thus, Option-B is the correct answer.
Both the process takes place in cell organelle which was considered as endosymbiotic organism. They are chloroplast and Mitochondria, Photosynthesis takes place in Chloroplast where as respiration takes place in mitochondria.
It was believed that a asteroid hit the Earth (specifically Mexico) when the asteroid hit it caused a freezing darkness due to dust and debris being kicked up by the asteroid . The dust and debris blocked the sunlight causing a temperature drop.
The keyword here is "area per volume" which is available in both cases. Besides capillaries are smaller than arteries they have in total more area as there are many vessels of then. The More the area/volum, the less the velocity
