Answer:
B) ecological succession
Explanation:
The analogy given in this question describes ECOLOGICAL SUCCESSION, which is the series of changes that an ecosystem undergoes over a period of time. Ecological succession is of two types viz: Primary succession and Secondary succession.
Primary succession involves the series of changes that occurs on a new habitat that has never been previously colonized. This is the case of the colonization of bare rocks with no plant life by LICHENS. The action of the lichen, which involves secretion of acids that disintegrates the rocks into soil, paves way for the colonization of that area by new species.
Lichens, via the role they play in primary succession by helping alter a barren area into a fertile one that accommodates other organisms, makes them be regarded as PIONEERS of primary succession.
1. Structure such as the human tailbone or appendix that evolution has reduced in size because it is no longer used = d. vestigial structure
2. study of the similarities and differences in the structures of different species:
= g. comparative anatomy
3. structure that is similar in related organisms because it was inherited from a common ancestor: = c. homologous structure
4. study of the similarities and differences in the embryos of different species: study of the similarities and differences in the embryos of different species = j. comparative embryology
5. scientist who finds and studies fossils to learn about evolution and understand the past:
= i. paleontologist
6. mistaken idea of jean baptiste lamarck that evolution occurs through the inheritance of traits that an organism develops in its own lifetime: = h. inheritance of acquired characteristics
7. process by which a single species evolves into many new species to fill available niches:
= e. adaptive radiation
8. relative ability of an organism to survive and produce fertile offspring: = k. fitness
9. structure that is similar in unrelated organisms because it evolved to do the same job, not because it was inherited from a common ancestor: = f. analogous structure
10. study of how and why plants and animals live where they do: = a. biogeography
11. process in which organisms evolve traits useful to humans because people select which individuals are allowed to reproduce and pass on their genes to successive generations:
= b. artificial selection
The answer is A
Because that would be the correct angle at the degree point which is pointing toward the top right
Answer:
The correct option is B <em>Pressure-sensitive baroreceptors uses tonic receptors which adapt slowly to the stimulus</em>
Explanation:
a. The thalamus receives stimulus from all of the five senses (sight, smell, taste, hear, touch). FALSE. Olfactory information is not sent to the thalamus for its process. The rest is.
b. Pressure-sensitive baroreceptors uses tonic receptors which adapt slowly to the stimulus. TRUE. Among the different types of tonic receptors, we may find baroreceptors, irritation receptors, tactile receptors, and proprioceptors. Tonic receptors characterize by their slow adaptation to the stimulus. The first discharge is maximal when the stimulus is received and then it progressively decreases. They send a continuous signal to the CNS.
c. The three layers that the retina is made of: photoreceptors, bipolar cells, rod cells. FALSE. There are in fact three layers in the retina: photoreceptors, bipolar cells, and ganglion cell layers. NOT rod cells.
d. The sense of smell uses phasic receptors which continuously fire as long as the stimulus is present. FALSE. Olfactive sense uses phasic receptors, but not continuously. These receptors shoot when they receive the stimulus, and then cease if the stimulus keeps constant.
