Answer:

B)speciation

Explanation:

Speciation is the term used to refer to the division of a lineage that produces two or more different species. In a nutshell, we can say that this is the process of the emergence of a new species, and the crucial event for this to happen is reproductive isolation. This reproductive isolation impedes the gene flow, therefore, obeying the biological concept of species, we say that a new species has emerged.

An example of speciation is shown in the question above, where a volcano separated two species and left them in reproductive isolation. The result of this was that two populations became so different from one another that they became unable to breed, creating new species.

gogolik [260]

Answer:A,B,D,E,F

Explanation:

Stock can be transfer depending on the organization.

The movement of stock is divide into three broad categories

Stock transfer from Plant to plant- movement of stock from a plant to another plant

Stock transfer from Company code to company code- movement from ome company code to another

Stock transfer from Storage location to storage location

Between different plants within the same storage - stock can be moved from one plant to another within the same storage this will lead to a change in quantity in both plant and it should be noted

Between storage locations within one plant- stock location can be change in a plant but it doesn't affect the quantity.

Between plants in different company code- stock can also be moved from one company code to another this requires adequate documentation when the stocked are moved.

What Earth science concept explains the process of the cooling of magma into porous rock? Explain your answer. plz answer correc
Zolol [24]
The concept would be crystallization. As magma cools inside or outside of the earth it crystallizes into an igneous rock. Intrusive (formed inside crust) igneous rocks are typically more course grained and contain many different noticeable minerals (for example, granite). Extrusive (formed outside) igneous rocks are typically more porous and are more fine grained then intrusive rocks (example, obsidian).

A signaling pathway that stimulates cellular growth and division is positively regulated by a GTPase encoded by an autosomally l
Romashka-Z-Leto [24]

Answer:

The correct answer is: a.

Explanation:

  • A Diploid organism possess two copies ( also called alleles) of each  autosomal gene, of which one copy of the gene is obtained from one of its parents and the other copy from its other parent.
  • During the process of replication, one of the alleles of the GTPase encoding gene undergoes a mis-sense mutation.
  • A Mis-sense mutation can be defined as a non-synonymous mutation in which one of the nucleotide in the sequence of the gene gets altered such that it causes a change in the amino acid encoded by the codon (triplet nucleotide message encoding for a single amino acid)  formed by the mutated nucleotide. A single amino acid change in the protein, if occurs in the functional site of the protein, can render a protein non-functional.
  • Hence, the mis-sense mutation in one of the alleles encoding for the GTPase gene causes the resulting protein produced from the mutated allele to have drastically reduced function (1%).
  • A heterozygous cell is one which has one copy of the normal allele and the other copy of the mutated allele of the GTPase encoding gene.
  • As one copy of the normal GTPase allele is present in such an individual, it can produce the normal GTPase protein that can assist in the process of cell growth and division.
  • Hence, the phenotype(expressed character) of  the heterozygous cell will not be affected due to the mutation and it will be able to grow and divide normally.
