The question is incomplete as it does not have the options-
a. superfluous organ
b. extra appendage
c. vestigial structure
d. living fossil
e. chromosomal aberration.
Answer:
The correct answer will be option-vestigial structure
Explanation:
Vestigial structure are the structures which do not play any role in the organisms but still are inherited from the ancestors to maintain the fitness of the organisms.
Vestigial organs are found in many organisms including humans in which the presence of vermiform appendix do not play any role but it used to play roles in the ancestors of humans as they carried the cellulose-degrading bacteria.
Thus, a vestigial structure is the correct answer.
Answer:
C) dwarf mistletoes, which parasitize particular species of forest tree
Explanation:
Uniform dispersion is observed in plant species that inhibit the growth of nearby individuals. For example, the sage plant, salvia leucophylla, secretes toxins, a phenomenon called negative allelopathy. Animals that maintain defined territories, such as nesting penguins, also exhibit uniform dispersion.
In lodgepole pine stands, spread of dwarf mistletoe into young trees is more extensive from single, isolated residual trees than from relatively uniform, dense, even-aged stands of residual trees.
Answer:
B.They hadn't turned the telescope toward the night sky.
The four principles of natural selection are variability among members of a species, heritability of the variable features, differences in population members' ability to reproduce and survival of the fittest in terms of variability, heritability and reproduction. Natural selection is one of evolution's four mechanisms.
