Answer:
<u>Option-(True):</u> The methodology used to discover the pattern of evolution among an assemblage of species is based on the assumption of descent with modification.
Explanation:
<u>Evolution and patterns of evolution:</u>
The phenomenon of evolution is very interesting as it can any two different species back to a common origin or ancestors. While the process of evolution does not occur in few years or centuries, as it takes millions of years for any specie to evolve from a less developed form of body or any system to a more complex or advance form.
Now, evolution occurs in many forms or patterns. As it species can originate from a single ancestor or descendant, while the evolution can occur inside the organism may occur in different patterns. These patterns are as follows:
- <u>Divergent Evolution:</u>The divergent evolution occurs when the species originated from a single ancestor or descendant results in different forms of organisms. As it brings diversity among the species belonging to same ancestors or origin. For example, the humans and apes.
- <u>Convergent Evolution: </u>The convergent evolution takes place inside the number of species when they are originated from the different species but they share the same medium or region to live in and share some of the similar resources between them. For example, The whales are mammals but they too live with the fish species inside the water.
- <u>Parallel Evolution:</u>When the evolved organisms or species are related to the different ancestors or descendants, as they share they do not share the same niche(way of life), as the species are unrelated to one another.
Geological change will not cause a mass extinction, because it happens on a too big scale - on the scale of millions of years. During such long time, it is more likely that other causes will influence the survival of extinction of species, such as climate change or environmental disasters, and even if there is a small influence, it would not be significant next to other causes.
Answer:basicallly what a hypothesis is something you belive in and your trying to prove it. It deifines the relationship between two varaiables.
Explanation:
DNA, nucleosome, coils, supercoils, chromosome.
Answer:
The answer is: Receptor A because the ligand concentration is greater than the Kd.
Explanation:
Receptor A because the ligand concentration is greater than the Kd., because the conformation of a receptor protein composes the functional state. Ligands include substrates, inhibitors, activators, and neurotransmitters. So, Affinity is a measure of the strength of attraction between a receptor and its ligand.
