Bingel [31]3 years ago
6 0

Answer:

Try this.

Explanation:

       I'm not too sure because the teacher never gave me enough information (Need Bigger Graph). Get bigger graph paper as it says "The X-axis should be years and the Y-axis should be coal production." On the X-axis (Horizontal Line) write "Years" and on the Y-Axis (Vertical Line) write "Coal Production."

Now, your gonna start listing all the years on the X-Axis 1996 through 2011, And on the Y-Axis list all the coal productions 145 and all the numbers through 634. Make sure you have the regions, Appalachian, Interior and Western.

     I'm sorry if this didn't help, this is what I did and it helped me, I thought it might help you too.

A species of fly lives in a canyon. Some of the flies prefer the side that gets sunlight during the day, while others prefer the
Dvinal [7]

Answer:

D. habitat preference

Explanation:

Habitat preference is one of the driving forces for ecological speciation that does not allow interbreeding between the members of a species. In habitat preference, some members of a species have a different preference for habitat than the others. They live in different habitats and do not interbreed. Over generations, these two populations of a species living in different habitats develop genetic variations and interbreed with the members of their own populations only. Gradually, these two populations would develop reproductive isolation and would evolve as two different species.

ValentinkaMS [17]
 1.The nucleus is often considered to be the cell's control center.
(because it contains the DNA)

2.The cytoplasm consists of everything inside the plasma membrane of the cell.
(actually it excludes the nucleus)

 3.The plasma membrane forms a boundary between the inside and outside of the cell. - it controls what can enter and what can't!


4.The cytoskeleton is essentially a "skeleton" inside the cell..
it maintains the form of the cell

5.The rough endoplasmic reticulum is covered with
Ribosomes -they make the proteins!


6.Lysosomes use enzymes to break down foreign matter and dead cells.

 7.plant cells cells specifically have a cell wall, a large central vacuole, and chloroplasts.-choloplasts are only found in plants!

Which of the following clades is most likely to survive a series of catastrophic events over time? (1 point)
marishachu [46]
The correct options are as follows:
1. D.
<span>A clade refers to a group of organisms that are made up of evolutionary descendants that originated from a common ancestor. A clade that will survive a series of catastrophic events must be one that is made up of distantly related and diverse species. This is because, those species will have different type of adaptability capacity and will be able to adapt in different ways to the catastrophic events. Due to the differences in their ability to adapt, some of the specie will survive the catastrophic events even if others are wipe out.

2. B.
The mass extinction of one specie usually creates space for another new specie to survive. The new specie that survive the old one may possess the ability to adapt to the event that wipe out the former set of living organisms and thus, the new specie will be able to occupy and reproduce in their new space. Mass extinction is said to occur when the whole population of living organism living in an ecosystem are wipe out as a result of unfavorable conditions.

3. B.
Convergent evolution refers to the independent evolution of similar features in species that arise from different lineages. The species involved usually evolve these traits as a result of having to adapt to similar environments. Convergent evolution usually result in evolution of analogous structures, that is, structures that have similar forms or functions but which are not present in the last common ancestors of the species.

4. C.
 In evolution, gradualism refers to theory that states that evolution occurs slowly and gradually, thus, large changes in evolution are actually product of small changes that occur over a long period of time. The theory of gradualism was originally proposed by James Hutton in 1795.

 5. C.
Mass extinction refers to the wiping out of a a large number of species within a very short time. Mass extinction can occur as a result of severe unfavorable conditions that all the species in an ecosystem can not adapt to. An instance of this is a drastic decrease in global temperature after several massive volcanic eruptions.</span>
