Answer:
Primary succession.
Explanation:
Ecological succession refers to the changes involved in the species structure of a community that is established in a particular habitat over time. The succession is of two types: the primary succession and secondary succession.
When the succession takes place on the barren land then succession is considered primary succession.
In the given question, the moss invades and colonizes the rocks and breaks them into the soil. Here the moss species is known as the pioneer species and since the moss grows on the barren rock, therefore, is considered the primary succession.
Thus, primary succession is correct.
Answer:
centromere.
explanation:
the contromere is the structure that joins the two chromatids to make a chromosome.
The morphological trait that shows the most variation among organisms exhibiting protostome development is the type of body cavity.
<h3>What are protostomes?</h3>
Protostomes are animals having bilateral symmetry in which the mouth is developed before the anus.
The organisms (protostomes) represent the main classification feature of animals according to the type of embryo development.
The genetic analysis of molecular sequences has shown that protostomes emerged first in the evolution in the animal kingdom.
Protostomes include diverse groups of animals such as annelids, nematodes, arthropods, mollusks, flatworms, etc.
In conclusion, the morphological trait that shows the most variation among protostomes is the type of body cavity.

<span>Meiosis I
Meiosis is the process of cell division by which involving gametes. Cell division is just the same for sperm and egg cells, but they have distinguishable descriptions and labels in the process. Spermatogenesis is for the males’ sperm cells and oogenesis is the process for females’ egg cells. The cell division of meiosis involves the two phases, respectively meiosis I and meiosis II. </span>Meiosis I like mitosis is the cell division that produces diploid cells<span>. These diploid cells are cells that contain a complete pair of chromosomes which is 46. The result is two diploid cells after the first meiosis. To provide clear explanation, in contrast haploid cells only contain 23 chromosomes and are created after meiosis II which is 4 in number.<span>
