Primary succession

Answers

The process, primary succession, would best describe the series of photographs when all of the topsoils were destroyed after the eruption. There is just one thing to remember about this, that the primary succession occurs on the land that has nothing and is the soil building process.  

Primary succession describes the process of the series of photographs. thus, option D is correct.

What is primary succession?

Primary succession, type of ecological succession (the evolution of a biological community’s ecological structure) in which plants and animals first colonize a barren, lifeless habitat. Species that arrive first in the newly created environment are called pioneer species, and through their interactions they build a simple initial biological community.

A biologist is in the process of classifying a newly discovered fungus. The observed characteristics include chitin in the cell walls and flagellated spores. To which group does the organism most likely belong?

Answers

Fungilike protocists.


The writer could assert Taxonomy. Which is responsible for many scientific classifications and influences in various field of life sciences or biology.  Evidences that Taxonomy uses to group or categorizes species range from 
1.       "Fossil Records 
2.       Comparative anatomy 
3.       Comparative embryology 
4.       Biochemical information 
5.       Cellular structure 
6.       Behavior" 
We also suggest that taxonomy has played various roles mainly in many aspects in Zoology, Botany, Anatomy and Physiology –aspects that include animal and human structures and functions. As the biotic community is so diverse it is classified to Biodiversity and the existence of properly assorting by set standard.

Where are most photosynthetic cells in plants found?

Answers

The correct answer is leaves. Leaves are the most photosynthetic cells in plants found. That is mainly because the sunlight goes through the leaves. The photosynthesis simply takes place first in leaves. They are the one responsible for the entrance of the carbon dioxide and the release of the oxygen.
Leaves are definitely where most of the photosynthetic cells are in plants. Since leaves are mostly flat and broad, they provide an ample surface for absorbing light.

Explanation:

Which of the following BEST describes a reason a trait exhibited by an organism will be passed on to its offspring?The trait results from isolation of the organism from the rest of the population.
The trait causes a change in the environment surrounding the organism.
The trait decreases the number of genes in the body cells of the organism.
The trait is due to the genetic code present in the organism’s gametes.

Answers

The correct answer for the question that is being presented above is this one: "The trait is due to the genetic code present in the organism’s gametes." The statement that BEST describes a reason a trait exhibited by an organism will be passed on to its offspring is that the trait is due to the genetic code present in the organism’s gametes.
