Shtirlitz [24]

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:

  1. <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.
  2. <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.
  3. <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.

Using data from the table above, select the best explanation for why that cell will be able to eliminate waste most efficiently?
fomenos
The correct option is this: CELL 2 WILL THE ONE THAT WILL BE ABLE TO ELIMINATE WASTES MOST EFFICIENTLY. This is because it has the highest surface area to volume ratio which facilitates the exchange of materials between a cell and its environment.
The rate of diffusion of materials into and out of the cell depends on the surface area to volume ratio of the cell. The higher this ratio, the higher the rate of diffusion.

The failure of the attempt to reintroduce clapper rails in California was an example of the _____.
Lemur [1.5K]

The correct answer is option D, difficulty of redesigning workable ecosystems

Reason -

The area that was redesigned into an ecosystem actually failed to attract the endangered species of clapper rails in California because of the following two reasons –

a) Failed attempt of restoration of Cord grass ( a tree which is a dominant tree in the nesting habitat of clapper rail) . Even if few such trees were there they could not grow to their full height and thus were incapable of providing adequate nesting cover

b) Due to the lack of predatory insect, some herbivore insect in the ecosystem attacked the green grasses thereby making the nesting inadequate.
