Answer:
Tissues in organs are precisely arranged so that they can work in harmony in performing organ functions. This is similar to an orchestra that contains various musical instruments, each of which is located in a precise place and contributes exactly at the right time to create harmony. Like musical instruments that are mixed and matched in various types of musical groups, tissues and cells also are present in several different organs and contribute their part to the function of the organ and the maintenance of homeostasis.
Answer:
1. Fossil record
2. Comparative anatomy
3. Embryology
4. Biogeography
Explanation:
Evolution is descent with modification. The organic evolution theory states that present complex life forms have evolved from the earlier (simpler) forms of life over time. Some of the most important pieces of evidence in support of the theory of organic evolution are:
1. Fossil record: fossils are dead remains of past living organisms preserved in the rocks of the remote past. These fossils demonstrate the existence of past living organisms that are related to present-day organisms.
2. Comparative anatomy refers to the study of similarities in the anatomy of different species, which provides direct evidence for identifying common ancestry between related species.
3. Embryology: the more recent the ancestor is that two species share, the greatest similarities in embryo structures and the more closely related the species are. In this regard, it is important to highlight that often homologous organs/structures (i.e., organs/structures descended from a common ancestor) can be observed only in embryos.
4. Biogeography refers to the spatial distribution of organisms and species. Species distribution reflects the evolutionary process when it is combined with geological change. For example, taxa that had already appeared before the separation of the continents are often distributed worldwide.
Answer:
Explanation:
The Brothers Karamazov by Fyodor Dostoyevsky.
Distinction: A Social Critique of the Judgement of Taste by Pierre Bourdieu. ...
Ulysses by James Joyce. ...
Atlas Shrugged by Ayn Rand.
Answer:
The correct answer would be behavioral.
Behavioral reproductive isolation is one of the methods that lead to speciation.
It is a type of prezygotic isolation in which species are isolated through differences in the mating signals and rituals.
For example, a particular pattern of dance, songs et cetera.
Similarly, jumping of a male bird in the opposite direction would not be recognized by the female bird due to which they would not be able to interbreed.
