Describe how detrital sedimentary rocks are classified.

1 answer:

3 0

Detrital sedimentary rocks are mainly classified by the size of their grain. The largest grain is a boulder, followed by a cobble, a pebble, sand, silt and finally the finest grain, which is clay. These grains of sediments are what get cemented together to form sedimentary rocks.

Answer:

The correct option is: A) sympatric speciation

Explanation:

Sympatric speciation is a type of geographic mode of speciation. It refers to the evolution of two or more than two new or descendant species from the existing common descent. The new species and the ancestral species all live in the same geographic area or location.

The common example of this speciation is insects like moths that become dependent on different plants belonging to the same geographical area.

DNA replication occurs prior to meiosis and _________.

Evgesh-ka [11]

A. Mitosis is the correct answer.

DNA replication occurs in the two major types of cell division: mitosis and meiosis.

Mitosis is the splitting of a normal cell into two daughter cells and involves complete replication of the cells DNA to produce two identical copies. Meiosis is a specialised and more complex two-stage form of cellular division related to sex cells and involves DNA replication followed by an exchange of DNA material within/between the chromosomes to mix genes from both parents and produce daughter cells with half the number of chromosomes as the original parent cell. Animal sperms and eggs are examples of cells produced by meiosis and contain half the number of chromosomes as normal cells. When combined during fertilization the egg and sperm produce a cell with the full compliment of chromosomes.

Cytokinesis is a part of the cellular life cycle that is related specifically to the division of the cytoplasm (basically the "soup" of material inside the cell). It is part of the cellular division process but not specifically related to nuclear division (i.e. DNA replication).

Transcription relates to the production of RNA from DNA which is then used for protein synthesis. DNA is not replicated during the transcription process, rather, this is a separate process critical for the production of proteins by the cell.

White raven [17]

Answer:

1. The chi-square statistic is 0. The p-value is 1. Not significant at p < .05.

The chi-square statistic with Yates correction is 0.0642. The p-value is .800028. Not significant at p < .05.

Explanation:

2. By generating large sets of data the ratio will remain same (F1 = 3:1, F2 = 9:3:3:1) according to the Chi-Square analysis. In actual reality, it fails to justify by giving a probability value of 1 that is impossible due to the exceptions of Co-Dominance and Incomplete Dominance...
